Posterior segment involvements including but not limited to peripheral vasculitis, optic disc inflammation, and macula edema documented based on medical records and various imaging modalities including wide field fluorescein angiography and optical coherence tomography, were noted. Demographic characteristics, accompanied with systemic diseases as well as duration and chronicity of uveitis, were also evaluated. Patients with significant systemic and ocular comorbidities were excluded. Statistical analyses including chi-squared tests and paired t-tests were employed.Results: Of the 44 patients with HLA-B27 associated uveitis, 22 patients (50%) were noted to demonstrate posterior segment involvement. Disc leakage and peripheral vasculitis were the most common findings of posterior involvement. Those with anterior chamber inflammation were found to have a significantly increased risk of posterior involvement. Those with posterior involvement were also noted to have a statistically significant decreased visual acuity. No significant association was found between documented duration of disease and posterior segment involvement.Conclusion: The prevalence of posterior segment involvement in HLA-B27 associated uveitis is higher compared to previous reports when evaluated with wide angle imaging modalities. Careful examination of the posterior segment is required in patients with HLA-B27 associated uveitis.Keywords: HLA-B27, uveitis, retinal vasculitis, vitreous haze, vitreous cells, macular edema, anterior chamber cells, anterior chamber flare

Magnitude of measured electrical response is known to vary with pupil size in conventional ffERG testing. The index study characterizes the relationship between magnitude of measured electrical activity and pupil size, both pupil diameter and pupil area, for this device.Methods: Seventeen patients (34 eyes) with no known ocular diseases were enrolled in the study. Electrophysiologic function of cone cells was evaluated using fixed-luminance flicker ffERG before and after dilation. Linear regression models, with inter-eye correlations controlled as fixed-effects, were used to characterize the effect of pupil dilation on the magnitude of the measured responses.Results: Mean age of study patients was 33.5 (standard deviation 7.4 years), and 35.3% of the subjects were female. Mean value of electrical response magnitude was 10.07± 2.79μV before dilation and 15.30± 4.08μV after dilation. The correlations of ERG magnitude with pupil diameter and with pupil area were not significant for either dilated or undilated eyes considered separately but were highly significant (p< 0.001) for dilated and undilated eyes considered in aggregate. ERG magnitude tended to increase by 1.08 μV for every 1 mm increase in pupillary diameter.Conclusion: An increase in pupil size, both pupil diameter and pupil area, is significantly associated with an increase in flicker ffERG magnitude recorded by the Diopsys device, suggesting that pupil size should be measured and considered when making clinical judgments based on the flicker ffERGs recorded by the device, and that pupil size-specific reference ranges could improve the clinical utility of the device.Keywords: electroretinogram, ERG, flicker ERG, pupil, magnitude, Diopsys

Following vitrectomy (PPV), we performed modified ILM surgical technique (IFT) in which ILM peel was stopped at the edges of the hole forming a floating ILM flap. Primary outcome measures were pattern of TMH closure and recovery of EZ. Student’s T-test and Pearson’s correlation coefficient were used for statistical analysis.Results: The study had 16 eyes of 16 patients. Mean baseline minimum linear diameter (MLD) was 562μ. Mean baseline best-corrected visual acuity (BCVA) was 1.4 logMAR. U-pattern closure occurred in 50% of eyes, V-pattern closure occurred in 31.2% of eyes, whereas W-pattern closure occurred in 18.7% of eyes. Mean BCVA improvement was 5 lines (p 0.02). Failure of recovery of EZ was detected in 75% of eyes. In the present series, neither pre-operative MLD nor time lapse prior to surgery were significant factors in determining the closure pattern of TMH, the grade of EZ recovery or final BCVA.Conclusion: Modified IFT is effective in promoting macular hole closure and improving visual acuity in patients with TMH. The technique does not promote recovery of EZ.Keywords: modified ILM surgical technique, traumatic FTMH, ILM peel adjuvants, ILM blue-assisted ILM peel, ellipsoid zone recovery

His vision was 20/20 in the right eye (OD) and 20/40 OS. Ophthalmic examination revealed left relative afferent pupillary defect, blurred optic nerve margin, creamy chorioretinal infiltration around the optic disc, and mild macular edema. OD examination was non-revealing. Chest CT scan with contrast showed calcified mediastinal lymph nodes, but biopsy of the lymph nodes was normal. Brain and orbit MRI demonstrated soft tissue abnormality with enhancement in left orbital apex with involvement of the extraocular muscles. CSF culture was negative, but complement fixation had positive titer of 1:2 for CI. The patient was diagnosed with CI meningitis, and antifungal therapy was initiated. Slight visual and symptomatic improvement was observed, which was not completely satisfactory. Biopsy of extraocular orbital muscle five months later revealed non-caseating granulomatous inflammation, leading to initiation of prednisone trial therapy. Nine months later, the patient was referred to a tertiary center owing to persistence of optic disc edema OS. PET CT was consistent with a diagnosis of sarcoidosis. Antifungal treatment was discontinued, and oral prednisone with methotrexate was initiated. Subsequently, methotrexate was replaced by infliximab to further manage ocular inflammation and neurologic symptoms which was effective. Vision was 20/20 OD and 20/30 OS at the most recent visit.Conclusion and Importance: Signs and symptoms of neurosarcoidosis and coccidioidomycosis can be similar and deceiving. The index case underscores importance of considering appropriate differential diagnoses in patients with similar symptoms and signs who may respond to preliminary designated treatment but not to the optimal extent. Considering such possibility could assist clinicians in managing the patients timely and efficiently.Keywords: neurosarcoidosis, coccidioidomycosis, sarcoidosis, ocular involvement

Both patients had vitrectomy and silicone oil injection. Preoperative imaging and intraoperative findings confirmed the perforating nature of the projectile.Results: In both patients, we detected eyelashes that were concealed either in the pars plana region or within vitreous exudates. Silicone oil was not removed in both patients to prevent phthisis bulbi and because there was no potential for visual improvement. The postoperative course in both cases was uneventful.Conclusion: Gunshot injuries can inoculate eyelashes impregnated with infectious microorganisms into the eye. In cases presenting with endophthalmitis associated with a gunshot injury, we recommend meticulous examination of the posterior segment and the pars plana region during vitrectomy to exclude the presence of occult lashes.Keywords: gunshot injury, endophthalmitis associated with perforating IOFB, post-traumatic endophthalmitis, case report

The eye in particular is one of few organs of the body for which gene therapy has received Food and Drug Administration approval, and it remains a field of great interest for gene therapy development. However, its associated immune and inflammatory reactions may render the treatment ineffective or harmful, which are of particular concern for the eyes due to their susceptibility to inflammation. The severity of immune and inflammatory reactions depends on the choice of vector and its route of administration. Furthermore, most preclinical and clinical studies have shown that the dose of vectors is correlated with the degree of humoral response and ocular inflammation. The route of administration directly impacts the degree of immune and inflammatory reaction. Subretinal delivery produces a weaker humoral response than the intravitreal route. However, some studies have demonstrated that the subretinal delivery induces a stronger inflammatory reaction. On the other hand, several instances of vision loss due to severe late onset intraocular inflammation were reported in a clinical trial involving intravitreal delivery of viral vectors. When compared with the intravitreal route, suprachoroidal gene delivery has been shown to produce weaker humoral response. However, unlike the subretinal space, the suprachoroidal space is not known to have immune privilege status. Inflammatory reactions following ocular gene therapy are typically mild and most clinical and preclinical studies have shown that they can be controlled with topical, local or systemic steroids. However, severe inflammatory responses may occur and require aggressive management to avoid permanent vision loss. Further investigations are required to elucidate and expand our knowledge of inflammatory reactions, and their optimal management, following ocular gene therapy.Keywords: ocular gene therapy, gene therapy, viral vectors, ocular inflammation, review

Six patients received IVHDM either once, as a preoperative medication, or at a lower dose than 500 mg, and were excluded. The remaining 14 patients received IVHDM for at least 4 months. Age (mean±SD) was 11.9± 2.4 years and 50% were female. Duration of treatment was 14.2± 7.5 months. Thirteen patients received IVHDM in combination with other immunomodulatory therapy (IMT). Except for two outliers, IVHDM was given at a dose of 8– 25 mg/kg per infusion. Three major adverse events (AEs) occurred in two patients: a single episode of bradycardia, compression fracture following minor trauma and adrenal insufficiency. The number of AEs (major and minor) strongly correlated with duration of treatment (p=0.004) and moderately correlated with the cumulative dose/weight (p=0.051). Weight gain was associated with the use of concomitant oral steroids and not with duration of treatment or cumulative dose.Conclusion: IVHDM may be a valid therapeutic option for aggressive/refractory pediatric uveitis. The reported AEs in this series can also be attributed to the concurrent IMT or the underlying disease itself.Keywords: pediatric uveitis, intravenous methylprednisolone, adverse events

Main outcome measures were final best-corrected visual acuity (BCVA), long-term globe survival and detection of complications. Spearman correlation analyzed relationships between numerical data. Kruskal–Wallis test compared differences in initial BCVA and final BCVA across variables. Categorical variables were tested using Chi square or Fisher’s exact test. P value is significant at 0.05.Results: The study included 103 eyes of 103 patients. Mean baseline BCVA was 0.01 decimal unit (2 logMAR). Mean duration from primary repair to PPV was 3 weeks. Mean duration of post-operative follow-up was 60 months. Mean final BCVA was 0.04 decimal unit (1.3 logMAR), p 0.001. Post-operatively, BCVA improved in 58.2% of patients. Nineteen patients (18%) gained ≥ 2 lines of vision, and 15 patients (14.5%) achieved final BCVA of 0.4 decimal unit (logMAR 0.4). All complications were related to the original injury. These included macular scar (19%), macular pucker (6%), recurrent retinal detachment (4%), subretinal fibrosis (3%), consecutive optic atrophy (3%), and PVR (3%). Phthisis bulbi or sympathetic ophthalmia did not develop in any case.Conclusion: PPV for removal of IOFB caused by gunshot injury yielded long-term favorable functional outcome with excellent globe survival. Poor initial BCVA, location of IOFB in the posterior pole, associated lens injury and retinal detachment are significant adverse prognostic factors for final BCVA but not for globe survival.Keywords: Intraocular foreign body; IOFB, ocular gunshot injury, penetrating ocular trauma, IOFB-associated endophthalmitis, pars plana vitrectomy for intraocular foreign body, PPV for IOFB

All patients had an axial length ≥ 26 mm. Main outcome measures were retinal re-attachment and macular hole closure after silicone oil removal, improvement of best-corrected visual acuity (BCVA), and complications secondary to surgery. Chi square/Fisher’s exact test was used to analyze categorical variables, while One-way ANOVA/Kruskal–Wallis test was used to compare variables across the closure type and complications. Correlations between numerical variables were tested using Spearman correlation. Kaplan–Meier method was used to estimate the event-free survival. P value is significant at 0.05.Results: The study included 26 eyes of 26 patients. Retinal re-attachment rate after primary and secondary surgeries was 88.4% and 100%, respectively. W-type macular hole closure occurred in 58% of eyes. Vision improved in 58% of eyes. Mean final BCVA was 0.05 decimal units, p = 0.004. Cataract and glaucoma developed in 42% and 15% of eyes, respectively. Initial BCVA, axial length and duration of silicone oil tamponade did not correlate significantly with either the type of macular hole closure or the final BCVA.Conclusion: PPV and silicone oil tamponade technique promotes successful anatomical and functional outcome in MRDMH. Long-term success is maintained after silicone oil removal. High incidence of silicone oil-induced complications mandate its removal from eyes with successful retinal re-attachment.Keywords: retinal detachment in high myopia, myopic macular hole, retinal detachment secondary to myopic macular hole, PPV for myopic retinal detachment associated with macular hole

The eyes were classified according to the etiology of macular hole into four groups: 79 eyes with idiopathic macular hole (IMH), 51 eyes with traumatic macular hole (TMH), 16 eyes with macular hole in diabetic patients (DMH) and 11 eyes with myopic macular hole (MMH). We classified the IMH group based on the International Vitreomacular Traction Study Classification according to size into 3 subgroups; subgroup 1: ≤ 250μ, subgroup 2: > 250 to 400μ and subgroup 3: ≥ 400 μ. All types of macular hole showed statistically significant postoperative improvement in BCVA compared to the baseline except cases with MMH. Anatomic postoperative hole closure was achieved in 86.1%, 60.7%, 43.65%, an 45.46% of eyes with IMH, TMH, DMH and MMH, respectively. In eyes with IMH, closure rate in subgroup 1 was significantly higher than in subgroups 2, and 3.Conclusion: PPV, ILM peel and C2F6 technique yielded variable anatomic and functional outcomes in different types of macular holes. Anatomic results were most favorable in IMH and least favorable in MMH. The smaller the diameter of the hole the better the results. The underlying pathogenetic mechanisms that lead to different types of macular holes are pivotal in determining the final outcome.Keywords: ILM peeling, macular holes, pars plana vitrectomy

Surgeries were performed between May 2011 and November 2016. Patients were followed up for at least 18 months after last intervention. The included eyes were categorized into two groups. Group A (vitrectomy with additional encircling band) included 72 eyes of 72 children; 58 boys and 14 girls. Group B (vitrectomy without encircling band) included 67 eyes of 67 children; 58 boys and 9 girls. In group A, the mean age was 9.21± 3.24. Attached retina was achieved in 61% (44 out of 72 eyes), of which 34 eyes remained attached after silicon oil removal, and 10 eyes remained attached under silicon oil tamponade. Recurrent RD under oil was present in 28 eyes (38.9%). In group B, the mean age was 11.06± 3.64. Attached retina was present in 61.2% (41 out of 67 eyes), of which 30 eyes remained attached after oil removal, and 11 eyes remained attached under silicon oil tamponade. Recurrent RD was present in 26 eyes (38.8%). In group A, the final visual acuity (VA) ranged from NLP to 0.5; 58.7% of patients achieved VA more than counting fingers at 1 meter, and 34.6% of patients achieved VA of 0.05 or more. In group B, the final postoperative VA ranged from NLP to 0.9; 16% of patients achieved VA from counting fingers at 1 meter to 0.05, and 29.2% achieved VA of 0.05 or more.Conclusion: Although no statistically significant difference between the two groups (combined vitrectomy and encircling band versus vitrectomy alone in pediatric traumatic retinal detachment), it is wise to consider adding encircling band in severe trauma cases.Keywords: trauma, pediatric retinal detachment, encircling band, pars plana vitrectomy, silicon oil

The study recruited patients who received 20 mg IVTA for treating various retinal and optic nerve diseases over the past 5 years. Main outcome measure was assessment of complications secondary to high-dose IVTA. The crosstabs procedure was used to display the interaction between the variables tested. The ANOVA test was used to analyze the differences among group means.Results: The study included 207 eyes of 168 patients. The main indication for high-dose IVTA were diabetic macular edema 64%, and macular edema secondary to retinal vein occlusion 19%. The mean follow-up period post-injection was 22 months. Mean number of injections was 1.3. Cataract developed in 54% of eyes. Glaucoma developed in 18.5% of eyes. Glaucoma surgery for intractable glaucoma attributed to high-dose IVTA was needed in 1% of eyes. Endophthalmitis and retinal detachment developed in one patient each.Conclusion: High-dose IVTA is a safe and cost-effective alternative to anti-VEGF agents. Cataract formation and intraocular pressure rise do not pose major adverse effects when weighed against the risk of vision loss due to inability to afford anti-VEGF treatment.

Hamouda Hamdy Ghoraba,1,2 Adel Galal Zaky,3 Amin Faisal Ellakwa31Ophthalmology Department, Faculty of Medicine, Tanta University, Tanta, 2Opthalmology Department, El Magrabi Eye Hospital, Tanta, 3Ophthalmology Department, Faculty of Medicine, Menoufia University, Cairo, EgyptObjective: The aim of this study was to report and compare the anatomic and functional results of primary vitrectomy with and without 360° encircling scleral buckle (SB) for the treatment of rhegmatogenous retinal detachment (RRD) due to inferior retinal break(s).Background: A variety of options, including SB, pars plana vitrectomy (PPV) with or without SB, and pneumatic retinopexy have been described as methods to repair RRDs. The use of additional SB with vitrectomy for RRD associated with inferior breaks has been a recent controversy after the introduction of transconjunctival cannula systems.Patients and methods: A retrospective, interventional, comparative case study was performed. In this study, we reviewed 105 consecutive patients who underwent vitrectomy for primary RRD with inferior retinal break(s) at the vitreoretinal center, performed by a single surgeon. Ninety four patients (94 eyes) were followed up for at least 4 months after silicon oil removal (SOR), and were analyzed. They were divided into two groups: group I included 50 patients who underwent PPV alone + silicon oil (SO); and group II included 44 patients who underwent PPV with 360° SB + SO. The essential parameters were single-operation success rate (SOSR) before SOR, incidence of retinal redetachment after SOR, and final visual acuity.Results: SOSR was obtained in 89 eyes (47 [94%] in group I and 42 [95.5%] in group II). From overall 59 phakic retinal detachments (RDs), SOSR was obtained in 56 eyes (30 in group I [93.8%] and 26 in group II [96.3%]) while from overall 35 aphakic or pseudophakic RDs, SOSR was obtained in 33 eyes (17 in group I [94.4%] and 16 in group II [94.1%]). Retinal redetachments after SOR occurred in three patients in group I and two patients in group II. Visual acuity improvement was greater in group I than in group II before SOR.Conclusion: Both surgical procedures had similar reattachment rates. The addition of 360° SB to PPV + SO might not have additional benefits in patients with RD due to inferior retinal break.Keywords: pars plana vitrectomy, scleral buckle, rhegmatogenous retinal detachment

Hammouda H Ghoraba,1,2 Ali Ahmed Ghali,3 Hosam Othman Mansour2,3 1Tanta University, Tanta, Egypt; 2Magrabi Eye Hospital, Cairo, Egypt; 3Al-Azhar University, Cairo, Egypt Purpose: To report a retrospective series of seven phakic eyes of seven patients suffering from a malignant glaucoma-like syndrome following pars plana vitrectomy and silicone oil (SO) injection.Materials and methods: Seven eyes with retinal detachment treated with pars plana vitrectomy with or without scleral buckling with SO tamponade. This was followed by cataract extraction to manage the elevated intraocular pressure (IOP).Results: This was a retrospective review of seven cases that received pars plana vitrectomy and SO with or without scleral buckling for different causes of retinal detachment (three were rhegmatogenous and four were tractional). After a period ranging from 1 week to 1 month, they presented with malignant glaucoma-like manifestations; high IOP, shallow axial anterior chamber, and remarkable decrease of visual acuity. Atropine eye drops and anti-glaucoma medical treatment (topical and systemic) had been tried but failed to improve the condition. Dramatic decrease of IOP and deepening of the axial anterior chamber was observed in all cases in the first postoperative day after phacoemulsification and posterior chamber foldable intraocular lens implantation with posterior capsulotomy.Conclusion: Aqueous misdirection syndrome may be observed following pars plana vitrectomy and SO tamponade. This must be differentiated from other causes of post vitrectomy glaucoma. Cataract extraction with posterior capsulotomy controls the condition. Keywords: malignant glaucoma, pars plana vitrectomy, silicone oil

Background: Repository corticotropin injection (RCI) has been suggested to exert immunomodulatory and anti-inflammatory effects in ocular inflammation. The index retrospective study aimed to evaluate the efficacy and tolerability of subcutaneous RCI in patients with active scleritis or uveitis., Main Body: Medical records of patients who were diagnosed with different types of active scleritis or uveitis and received RCI for more than six months at a tertiary eye center were reviewed. Patient characteristics including age, sex, comorbidities, clinical findings, treatment details, and adverse events were recorded. A total of 17 eyes of 17 patients were included. Median age was 43 years old and 53% of patients were male. Mean treatment duration was 25.4 ± 15.5 months. Indications for RCI therapy were scleritis (7 anterior and 1 posterior) (47.8%), panuveitis (17.4%), retinal vasculitis (17.4%), chronic/recurrent anterior uveitis (13%), and posterior uveitis (4.35%). RCI was initiated at a dose of 40 to 80 units 3 times weekly. Given the adequate control of inflammation, RCI was successfully discontinued in four patients (23.5%). Prior to RCI therapy, 14 (82.3%) patients were on oral prednisone at an average of 10 mg daily (range 2.5-40 mg), and two (11.7%) patients discontinued prednisone immediately before initiating RCI due to side effects. After six months of therapy, the prednisone dose was reduced in four (23.5%) patients to an average of 3 mg daily (range 1-5 mg) and was stopped in eight (53%) patients. Concomitant immunomodulatory therapies (IMTs) included mycophenolate mofetil (23.5%) and methotrexate (23.5%), and adalimumab (23.5%). Ten patients were on IMTs prior to using RCI, and during the course of treatment, IMT was stopped in two patients and reduced in one. Side effects included insomnia (23%), hypertension (11.7%), lower extremity edema (11.7%), hyperglycemia (11.7%), weight gain (11.7%), and infection (5.8%)., Conclusion: RCI may be considered as a potential therapy with acceptable tolerability for patients with non-infectious scleritis or uveitis., (© 2024.

Purpose: To report a case of neovascular glaucoma in an 8-year-old male, secondary to a racemose hemangioma without associated intracranial arteriovenous malformation, highlighting the challenges in management and novel findings on optical coherence tomography angiography (OCTA)., Observations: An 8-year-old male initially presented with pain, redness, and blurred vision in the right eye. The patient was diagnosed with secondary neovascular glaucoma due to a racemose hemangioma. Urgent interventions included intravitreal bevacizumab injection and tube shunt surgery for persistently high intraocular pressure. Pars plana vitrectomy and scatter laser photocoagulation were eventually performed to manage a tractional retinal detachment and peripheral ischemia, respectively. OCTA imaging revealed a racemose hemangioma with a unique chorioretinal anastomosis., Conclusions and Importance: We present a rare pediatric case of neovascular glaucoma secondary to a racemose hemangioma with significant peripheral ischemia and an unusual chorioretinal anastomosis. The discovery of a chorioretinal anastomosis on OCTA suggests a potentially severe variant of racemose hemangioma., Competing Interests: The authors have no conflict of interest., (© 2024 The Authors.

Purpose: The index review aims to provide an update on the role of corticosteroids and steroid-sparing immunomodulatory therapy (IMT) in managing patients with infectious uveitis., Method: Narrative literature review., Results: Corticosteroids and immunomodulatory therapy (IMT) focus on the host defense system instead of the pathogen, adjusting exaggerated inflammatory reactions to reduce potential harm to ocular tissues. Systemic or local corticosteroids are primarily selected as adjunctive medication for infectious uveitis. Concomitant corticosteroids have also been used in cases of paradoxical worsening in ocular tuberculosis and immune recovery uveitis in cytomegalovirus (CMV) retinitis. While there is no well-established evidence to support the use of IMT in infectious uveitis, it is occasionally used in clinical settings to treat persistent inflammation following resolution of infection such as cases of ocular tuberculosis and ocular syphilis where an insufficient response is observed with corticosteroids., Conclusion: There is no consensus on the position of immunomodulatory therapy in the management of infectious uveitis with different etiologies. The index review provides an overview of available adjunctive corticosteroids and IMT options to assist clinicians in managing such disease entities more efficiently.

Purpose: To ascertain whether the use of ultra-wide-field fluorescein angiography (UWFFA) at baseline visit alters the assessment of disease activity and localization, as well as the management of patients presenting to a tertiary uveitis clinic., Design: Retrospective comparison of diagnostic approaches., Methods: Baseline visits of 158 patients who presented to the Uveitis Clinic at the Byers Eye Institute at Stanford between 2017 and 2022 were evaluated by 3 uveitis-trained ophthalmologists (I.K., A.B., and H.G.). Each eye had undergone clinical examination along with ultra-wide-field fundus photography (UWFFP) (Optos Plc), spectral-domain optical coherence tomography (SD-OCT, Spectralis Heidelberg, Heidelberg Engineering) and UWFFA (Optos Plc) at the baseline visit. Investigators were asked to successively determine disease activity, localization of disease (anterior, posterior or both), and management decisions based on clinical examination and UWFFP and SD-OCT (Set 1) and Set 1 plus UWFFA (Set 2). The primary outcome was the percentage of eyes whose management changed based on the availability of UWFFA compared with Set 1., Results: The mean age of the patients was 46.9 ± 22.4 years (range, 7-96), and 91 (57.6%) were female. With Set 1 alone, 138 eyes (55.2%) were found to have active disease; localization was anterior in 58 eyes (42.0%), posterior in 53 eyes (38.4%), and anterior + posterior in 27 eyes (19.6%). With Set 2, 169 eyes of 107 patients had active anterior, posterior, or panuveitis. In comparison with Set 1, assessment with Set 2 identified additional 31 eyes (18.3%) with active disease (P = .006) and an additional 31 eyes (18.3%) having disease in both anterior + posterior segments (P < .001). Regarding the primary outcome, management was changed in 68 eyes (27.4%) in Set 2 compared with Set 1., Conclusions: Baseline UWFFA may alter assessment of disease activity, localization, and management decisions compared with clinical examination with only UWFFP and SD-OCT for eyes with uveitis. Thus, UWFFA may be considered as an essential tool in the evaluation of patients with uveitis at the baseline visit., (Copyright © 2024. Published by Elsevier Inc.)

Introduction: The objective of this study was to determine the sensitivity of brain magnetic resonance imaging (MRI) in the detection of choroidal metastasis (CM) from systemic primary cancers., Methods: A retrospective chart review identified patients with clinically confirmed CM seen on the Oncology Service (Byers Eye Institute) between January 2018 and March 2022. Patients had an MRI brain and/or orbits performed within 3 months of CM diagnosis. Evaluation of CM detection by MRI was then divided into two parts: an initial "standard read," where determination of CM detection was based solely on the original radiology report, to reflect real-world performance, and a subsequent "dedicated read," for which a board-certified neuroradiologist, blinded to the laterality and location of the CM, reevaluated the studies to provide an objective "gold standard" interpretation regarding the radiographic detection of CM., Results: The study included 42 eyes of 40 patients with confirmed CM. On standard read, MRI detection of CM occurred in 21 of 42 eyes (50%), with no significant difference between MRI brain and orbit protocols ( p = 0.249). Features associated with improved detection were increased tumor basal diameter ( p < 0.001) and ultrasonographic tumor thickness ( p = 0.003). On dedicated read, MRI detection of CM improved to 26 of 33 eyes (76%; limited to eyes with full complement of pre- and post-gadolinium sequences). Post-gadolinium 3D fluid-attenuated inversion recovery (FLAIR) sequence with fat suppression was the most sensitive (88%) for CM detection. 42% and 58% of lesions were visualized using conventional pre-gadolinium T1- and T2-weighted imaging, respectively., Conclusions: MRI sensitivity to detect CM improved from 50% to 76% with focused reinterpretation. Increased utilization of the post-gadolinium 3D FLAIR sequence and increased ocular scrutiny in cancer patients undergoing brain imaging may facilitate earlier diagnosis of CM., Competing Interests: The authors report no conflicts of interest.

Background: Ocular inflammatory diseases, including scleritis and uveitis, have been widely treated with immunomodulatory therapies (IMTs) as a steroid-sparing approach. Such strategy includes conventional therapies (antimetabolites, alkylating agents, and calcineurin inhibitors) as well as biologic agents like adalimumab, infliximab, rituximab, and tocilizumab. Cyclophosphamide (CP) is an alkylating agent and mainly inhibits the functioning of both T and B cells. Though known to have potential adverse events, including bone marrow suppression, hemorrhagic cystitis, and sterility, CP has been shown to be efficacious, especially in recalcitrant cases and when used intravenous (IV) for a limited period., Main Findings: We conducted a retrospective case-series to assess the safety and efficacy of CP therapy for patients with severe ocular inflammatory diseases who failed other IMTs. Medical records of 1295 patients who presented to the Uveitis Clinic at the Byers Eye Institute at Stanford between 2017 and 2022 were reviewed. Seven patients (10 eyes) who received CP therapy for ocular inflammatory diseases with at least one year of follow-up were included. The mean age of the patients (4 males, 3 females) was 61.6 ± 14.9 (43.0-89.0) years. Clinical diagnoses included necrotizing scleritis (5 eyes), peripheral ulcerative keratitis (2 eyes), orbital pseudotumor (1 eye), HLA-B27 associated panuveitis and retinal vasculitis (2 eyes). Ocular disease was idiopathic in 3 patients, and was associated with rheumatoid arthritis, IgG-4 sclerosing disease, dermatomyositis, and ankylosing spondylitis in 1 patient each. All the patients had history of previous IMT use including methotrexate (5), mycophenolate mofetil (3), azathioprine (1), tacrolimus (1), adalimumab (2), infliximab (4), and rituximab (1). The mean follow-up time was 34.4 ± 11.0 (13-45) months, and mean duration of CP therapy was 11.9 ± 8.8 (5-28) months. Remission was achieved in 5 patients (71.4%). Four patients (57.1%) experienced transient leukopenia (white blood cell count < 4000/mL)., Short Conclusion: CP therapy can be considered a potentially effective and relatively safe therapeutic option for patients with severe ocular inflammatory diseases who failed other IMTs including biologics (TNFa and CD20 inhibitors)., (© 2024.

Participants: This article includes 7293 infants (14 586 eyes) screened for ROP across 5 centers in the United States (Austin Retina Associates, Austin, TX; Bascom Palmer Eye Institute, Miami, FL; Beaumont Eye Institute, Royal Oak, MI; Massachusetts Eye and Ear, Boston, MA; and Stanford Byers Eye Institute, Stanford, CA)., Purpose: To analyze the incidence and timing of treatment requiring retinopathy of prematurity (ROP) in extremely small premature infants. We hypothesize that the smaller the infant by gestational age and birthweight, the higher their likelihood of requiring treatment for ROP., Design: Premature infants screened for Retinopathy of Prematurity from 2002-2022 were divided into cohorts based on the following criteria based on gestational age (GA) and birth weight (BW). "Micropremature infants" are infants born between 24-26 weeks GA and between 600-799 g BW. "Nanopremature infants" are born ≤ 24 weeks GA and ≤ 600 g BW., Methods: Retrospective chart review., Main Outcome Measures: The incidence and timing of treatment-requiring ROP., Results: We found that infants defined as nanopremature had a ∼63% chance of requiring treatment at an average postmenstrual age (PMA) of 36.6 weeks, whereas those defined as micropremature had a 30% chance of requiring treatment at an average PMA of 36.3 weeks. This significantly contrasts with the risk of all screened babies for ROP where the risk of requiring treatment was 8.5%., Conclusion: Micropremature and nanopremature infants are significantly more likely to require treatment for ROP. With demographic data matched to all 5 major US regions spanning the last decade, these results have the potential to inform neonatologists, pediatricians, and ophthalmologists of an important shift in the landscape of prematurity in the United States., Financial Disclosure(s): Proprietary or commercial disclosure may be found in the Footnotes and Disclosures at the end of this article., (Copyright © 2023 American Academy of Ophthalmology.

Purpose: To describe the various ocular clinical features and visual outcomes in Tubulointerstitial Nephritis and Uveitis Syndrome (TINU)., Methods: The medical records of 13 patients (26 eyes) diagnosed with TINU were reviewed., Results: Twenty-six (26) eyes of 13 patients with TINU were reviewed in this study. The median age at onset of uveitis was 14 (range, 9-45). Eight (61.5%) subjects were female. The median follow-up of patients was 30 months (range, 6-89 months). Posterior segment findings were seen in 18 eyes of 9 patients (69.2%). The most common posterior findings were optic nerve head inflammation (16 eyes, 88.8%) and retinal vasculitis (13 eyes, 72.2%). Other posterior findings included vitritis (8 eyes, 44.4%), macular edema (6 eyes, 33.3%), snowball (4 eyes, 22.2%), and chorioretinal lesions (2 eye, 11.1%). Eight patients had fluorescein angiography (FA) data available and most eyes had retinal capillary leakage (13 eyes, 81.2%) followed by optic disc staining/leakage (12 eyes, 75%). Twelve (12) patients (92.3%) were treated with immunomodulatory treatment (IMT) and/or biologics. Five patients (%38.4) required biologics to control intraocular inflammation., Conclusion: Posterior segment involvement may be common in patients with TINU syndrome. FA provides significant information for detecting posterior segment involvement and disease activity in TINU. The majority of patients required systemic treatment in order to control intraocular inflammation and prevent relapses., (© 2023.

Objective: To evaluate the functional implications of angiographic macular leakage without the presence of intraretinal fluid on optical coherence tomography (OCT) in eyes with intermediate, posterior, or panuveitis., Methods: Retrospective study on patients with a diagnosis of intermediate, posterior, or panuveitis. Patients who had fluorescein angiography, OCT, and multifocal electroretinography (mfERG) within a predetermined time frame were included. Demographic and clinical data including types of ocular inflammation and best-corrected visual acuity (BCVA), in addition to OCT, fluorescein angiography, and mfERG data were collected. The study cohort was divided into 2 groups based on the presence of angiographic macular leakage and macular edema (ME): group 1 (no ME and no macular leakage) and group 2 (presence of macular leakage without ME)., Results: A total of 29 patients (43 eyes) were included in the study, with 13 patients (17 eyes) in group 1 and 16 patients (26 eyes) in group 2. No statistically significant differences in age, sex, anterior-chamber cells, lens status, vitreous cells, vitreous haze, BCVA, or mean central subfoveal thickness were found between groups 1 and 2. All mfERG values, including N 1 and P 1 response densities and timings for rings 1-5, did not show any statistically significant difference between group 1 and 2. No correlation was found between either BCVA or central subfoveal thickness and any of mfERG values for rings 1-3., Conclusions: In absence of ME, angiographic macular leakage in eyes with uveitis might not be associated with worse macular function when compared with eyes without angiographic macular leakage., (Copyright © 2022 Canadian Ophthalmological Society.

Background: To describe longitudinal changes in patients with non-paraneoplastic autoimmune retinopathy (npAIR) by utilizing different diagnostic modalities/tests., Methods: The index study is a retrospective longitudinal review of sixteen eyes of eight patients from a tertiary care eye hospital diagnosed with npAIR. Multiple diagnostic modalities such as wide-angle fundus photography (WAFP), WA fundus autofluorescence (WAFAF), spectral-domain optical coherence tomography (SD-OCT), Goldmann visual field (GVF) perimetry, microperimetry (MP), electrophysiologic testing, and adaptive optics scanning laser ophthalmoscopy (AOSLO) were reviewed and analyzed., Results: At the baseline visits, anomalies were detected by multimodal diagnostic tests on all patients. Subjects were followed up for a median duration of 11.5 [3.0-18.7] months. Structural changes at the baseline were detected in 14 of 16 (87.5%) eyes on WAFP and WAFAF and 13 of 16 (81.2%) eyes on SD-OCT. Eight of the ten (80%) eyes that underwent AOSLO imaging depicted structural changes. Functional changes were detected in 14 of 16 (87.5%) eyes on GVF, 15 of 16 (93.7%) eyes on MP, and 11 of 16 (68.7%) eyes on full-field electroretinogram (ff-ERG). Multifocal electroretinogram (mf-ERG) and visual evoked potential (VEP) tests were performed in 14 eyes, of which 12 (85.7%) and 14 (100%) of the eyes demonstrated functional abnormalities, respectively, at baseline. Compared to all the other structural diagnostic tools, AOSLO had a better ability to demonstrate deterioration in retinal microstructures occurring at follow-ups. Functional deterioration at follow-up was detected on GVF in 8 of 10 (80%) eyes, mf-ERG in 4 of 8 (50%) eyes, and MP in 7 of 16 (43.7%) eyes. The ff-ERG and VEP were stable in the majority of cases at follow-up., Conclusions: The utilization of multimodal imaging/tests in the diagnosing and monitoring of npAIR patients can aid in identifying anomalous changes over time. Analysis of both the anatomical and functional aspects by these devices can be supportive of detecting the changes early in such patients. AOSLO shows promise as it enables the capture of high-resolution images demonstrating quantifiable changes to retinal microstructure.

Purpose: This study was conducted to evaluate the association of oral montelukast, selective antagonism for cysteinyl leukotriene receptor 1, with reduced odds of exudative age-related macular degeneration (exAMD) development., Methods: This case-control study was conducted using institutional cohort finder tool, and included 1913 patients with exAMD (ICD: H35.32 and 362.52) and 1913 age- and gender-matched control subjects without exAMD. Subanalysis among 1913 exAMD and 324 nonexudative AMD was also conducted., Results: A total of 47 (2.5%) exAMD cases were identified to have a history of oral montelukast use before exAMD diagnosis, compared with 84 (4.4%) controls. Montelukast usage was significantly associated with reduced odds of exAMD in the multivariable analysis (adjusted odds ratio [OR]: 0.50, 95% confidence interval: 0.31-0.80) and nonsteroidal anti-inflammatory drug usage (adjusted OR: 0.69). Caucasian race, history of smoking, and nonexudative macular degeneration in either eye were also found to have a significant relationship with increased odds of exAMD. In the subanalysis, montelukast usage showed significant association with reduced odds of developing exAMD from nonexudative AMD (adjusted OR: 0.53, 95% confidence interval: 0.29-0.97) and the presence of atopic disease (adjusted OR: 0.60)., Conclusion: The study results suggested that oral montelukast is linked to reduced odds of exAMD development.

Identifying and planning treatment for retinopathy of prematurity (ROP) using telemedicine is becoming increasingly ubiquitous, necessitating a grading system to help caretakers of at-risk infants gauge disease severity. The modified ROP Activity Scale (mROP-ActS) factors zone, stage, and plus disease into its scoring system, addressing the need for assessing ROP's totality of binocular burden via indirect ophthalmoscopy. However, there is an unmet need for an alternative score which could facilitate ROP identification and gauge disease improvement or deterioration specifically on photographic telemedicine exams. Here, we propose such a system (Telemedicine ROP Severity Score [TeleROP-SS]), which we have compared against the mROP-ActS. In our statistical analysis of 1568 exams, we saw that TeleROP-SS was able to return a score in all instances based on the gradings available from the retrospective SUNDROP cohort, while mROP-ActS obtained a score of 80.8% in right eyes and 81.1% in left eyes. For treatment-warranted ROP (TW-ROP), TeleROP-SS obtained a score of 100% and 95% in the right and left eyes respectively, while mROP-ActS obtained a score of 70% and 63% respectively. The TeleROP-SS score can identify disease improvement or deterioration on telemedicine exams, distinguish timepoints at which treatments can be given, and it has the adaptability to be modified as needed., (© 2023.

Background: Macular hole (MH) is a full-thickness defect in the central portion of the retina that causes loss of central vision. According to the usual definition, a large MH has a diameter greater than 400 µm at the narrowest point. For closure of MH, there is evidence that pars plana vitrectomy (PPV) with internal limiting membrane (ILM) peeling achieves better anatomical outcomes than standard PPV. PPV with ILM peeling is currently the standard of care for MH management; however, the failure rate of this technique is higher for large MHs than for smaller MHs. Some studies have shown that the inverted ILM flap technique is superior to conventional ILM peeling for the management of large MHs., Objectives: To evaluate the clinical effectiveness and safety of pars plana vitrectomy with the inverted internal limiting membrane flap technique versus pars plana vitrectomy with conventional internal limiting membrane peeling for treating large macular holes, including idiopathic, traumatic, and myopic macular holes., Search Methods: The Cochrane Eyes and Vision Information Specialist searched CENTRAL, MEDLINE, Embase, two other databases, and two trials registries on 12 December 2022., Selection Criteria: We included randomized controlled trials (RCTs) that evaluated PPV with ILM peeling versus PPV with inverted ILM flap for treatment of large MHs (with a basal diameter greater than 400 µm at the narrowest point measured by optical coherence tomography) of any type (idiopathic, traumatic, or myopic)., Data Collection and Analysis: We used standard methodological procedures expected by Cochrane and assessed the certainty of the body of evidence using GRADE., Main Results: We included four RCTs (285 eyes of 275 participants; range per study 24 to 91 eyes). Most participants were women (63%), and of older age (range of means 59.4 to 66 years). Three RCTs were single-center trials, and the same surgeon performed all surgeries in two RCTs (the third single-center RCT did not report the number of surgeons). One RCT was a multicenter trial (three sites), and four surgeons performed all surgeries. Two RCTs took place in India, one in Poland, and one in Mexico. Maximum follow-up ranged from three months (2 RCTs) to 12 months (1 RCT). No RCTs reported conflicts of interest or disclosed financial support. All four RCTs enrolled people with large idiopathic MHs and compared conventional PPV with ILM peeling versus PPV with inverted ILM flap techniques. Variations in technique across the four RCTs were minimal. There was some heterogeneity in interventions: in two RCTs, all participants underwent combined cataract-PPV surgery, whereas in one RCT, some participants underwent cataract surgery after PPV (the fourth RCT did not mention cataract surgery). The critical outcomes for this review were mean best-corrected visual acuity (BCVA) and MH closure rates. All four RCTs provided data for meta-analyses of both critical outcomes. We assessed the risk of bias for both outcomes using the Cochrane risk of bias tool (RoB 2); there were some concerns for risk of bias associated with lack of masking of outcome assessors and selective reporting of outcomes in all RCTs. All RCTs reported postoperative BCVA values; only one RCT reported the change in BCVA from baseline. Based on evidence from the four RCTs, it is unclear if the inverted ILM flap technique compared with ILM peeling reduces (improves) postoperative BCVA measured on a logarithm of the minimum angle of resolution (logMAR) chart at one month (mean difference [MD] -0.08 logMAR, 95% confidence interval [CI] -0.20 to 0.05; P = 0.23, I 2 = 65%; 4 studies, 254 eyes; very low-certainty evidence), but it may improve BCVA at three months or more (MD -0.17 logMAR, 95% CI -0.23 to -0.10; P < 0.001, I 2 = 0%; 4 studies, 276 eyes; low-certainty evidence). PPV with an inverted ILM flap compared to PPV with ILM peeling probably increases the proportion of eyes achieving MH closure (risk ratio [RR] 1.10, 95% CI 1.02 to 1.18; P = 0.01, I 2 = 0%; 4 studies, 276 eyes; moderate-certainty evidence) and type 1 MH closure (RR 1.31, 95% CI 1.03 to 1.66; P = 0.03, I² = 69%; 4 studies, 276 eyes; moderate-certainty evidence). One study reported that none of the 38 participants experienced postoperative retinal detachment., Authors' Conclusions: We found low-certainty evidence from four small RCTs that PPV with the inverted ILM flap technique is superior to PPV with ILM peeling with respect to BCVA gains at three or more months after surgery. We also found moderate-certainty evidence that the inverted ILM flap technique achieves more overall and type 1 MH closures. There is a need for high-quality multicenter RCTs to ascertain whether the inverted ILM flap technique is superior to ILM peeling with regard to anatomical and functional outcomes. Investigators should use the standard logMAR charts when measuring BCVA to facilitate comparison across trials., (Copyright © 2023 The Cochrane Collaboration. Published by John Wiley & Sons, Ltd.)

Purpose: To evaluate the efficacy of infliximab (IFX, 5-10 mg/kg) (Group 1) and tocilizumab (TCZ, 4-8 mg/kg) (Group 2) infusions in non-infectious retinal vasculitis (RV) using Angiographic Scoring for the Uveitis Working Group fluorescein angiography (FA) scoring system., Methods: Records of 14 patients (24 eyes) in Group 1 and 8 patients (11 eyes) in Group 2 were retrospectively evaluated to assess visual acuity (VA), anterior chamber cell and flare, vitreous haze, central subfield thickness (CST), and FA scoring at baseline and 6 months of follow-up. The measurements were employed to grade in each group., Results: In Group 1 and 2, respectively, there was no underlying disease in 9 (60%) and 3 (42.9%) patients. Three (42.9%) patients in Group 2 had juvenile idiopathic arthritis (JIA) as the most common identified cause. Mean improvement in VA (log MAR) and CST were 0.04 ± 0.14 and 40.3 ± 78.5 µm in Group 1; 0.04 ± 0.09 and 47.3 ± 82.3 µm in Group 2, respectively. Mean FA scores were significantly reduced from 12.4 ± 5.2 and 11.6 ± 4.4 at baseline to 6.4 ± 5.0 and 5.8 ± 3.9 at 6-month in Group 1 and 2, respectively. In Group 2, 9 eyes of 6 patients (75%) had the history of IFX use prior to TCZ initiation. There was no significant safety concern requiring treatment discontinuation during the follow-up in either group., Conclusion: IFX and TCZ infusions showed statistically significant improvement of non-infectious RV as shown by ASUWOG FA Scoring System. TCZ, as well as IFX, appeared to be effective treatment options for non-infectious RV., (© 2022. The Author(s), under exclusive licence to The Royal College of Ophthalmologists.)

Purpose: Diopsys® NOVA™ is a novel full-field electroretinography (ffERG) device that can make rapid measurements of retinal electrophysiologic function. Diagnosys® Espion 2™ is a clinical gold-standard ERG device. This study aimed to investigate whether light-adapted Diopsys® NOVA™ fixed-luminance flicker ffERG magnitude and implicit time (converted from phase) measurements correlate with light-adapted Diagnosys® Espion 2™ flicker ffERG amplitude and implicit time measurements, respectively., Methods: Twelve patients (22 eyes) with various retinal and uveitic diseases underwent light-adapted Diagnosys® Espion 2™ and Diopsys® NOVA™ fixed-luminance flicker testing. Diopsys® magnitude and implicit time (converted from phase) measurements were compared to Diagnosys® amplitude and implicit time measurements, and a Pearson correlation was used to evaluate any existing correlation. Groups were also compared using generalized estimating equations. Bland-Altman plots were utilized to determine agreement between the comparison groups., Results: Age of patients ranged from 14 to 87 years. 58% (n = 7/12) of patients were female. A significant, positive correlation (r = 0.880, P < 0.001) was observed between magnitude (Diopsys®) and amplitude (Diagnosys®) measurements. Amplitude increases by 6.69 µV for each 1 µV increase in Magnitude (p-value < 0.001). A statistically significant, strong positive correlation was observed between Diopsys® implicit time measurements (converted from phase) and Diagnosys® implicit time measurements (r = 0.814, p-value < 0.001). For each 1 ms increase in Diopsys® implicit time, Diagnosys® implicit time increases by 1.13 ms (p-value < 0.001)., Conclusions: There is a statistically significant positive correlation between light-adapted Diopsys® NOVA™ fixed-luminance flicker amplitude and Diagnosys® flicker magnitude values. Additionally, there is a statistically significant positive correlation between Diopsys® NOVA™ fixed-luminance flicker implicit time (converted from phase) and Diagnosys® flicker implicit time values. These results imply that the Diopsys® NOVA™ module, which utilizes the nonstandard shortened International Society for Clinical Electrophysiology of Vision (ISCEV) ERG protocol, can produce reliable light-adapted flicker ffERG measurements., (© 2023.

Retinitis pigmentosa (RP) is an inherited bilateral retinal degenerative disease with an incidence of 1 in 4000 people. RP affects more than 1 million individuals worldwide. Although night blindness and restricted visual field are the most typical symptoms of these individuals, generalized vision loss due to cataracts can be expected in the latter stages of the disease. It has been demonstrated that posterior subcapsular cataract is the most prevalent cataract in younger individuals with RP, as opposed to age-related cataracts. Although most ophthalmologists may have a negative view of cataract surgery in patients with RP, it appears that it can play an important role in the visual restoration of patients with RP. However, there are concerns about performing cataract surgery for patients with RP. Herein, a systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses on databases of MEDLINE and Scopus., (Copyright © 2022 The Author(s).

Purpose: This index study highlights the efficacy and safety of a combined surgical and medical therapy (with intraocular and systemic methotrexate) of pediatric rhegmatogenous retinal detachments (RRD) complicated by proliferative vitreoretinopathy (PVR)., Methods: Three pediatric patients with RRD complicated by PVR in the setting of underlying atopic dermatitis and/or uveitis who were treated with a combination of vitreoretinal surgery and intraoperative intravitreal methotrexate (MTX) (40mg) infusion, followed by at least one injection of 200 μg of MTX into the silicone oil-filled vitreous cavity, are reported. In addition, the patients received short-term systemic immunosuppression with systemic (oral or subcutaneous 20 mg weekly MTX for 12 weeks) and/or steroids., Results: Retinal reattachment with improvement in visual acuity was achieved in all eyes following a single surgery and remained to the final follow-up examination after oil removal. There were no observed side effects of intraocular or systemic MTX., Conclusions: The safety and efficacy of this combination therapy suggests that it could be a successful strategy for treating pediatric patients with RRD with or without PVR in the presence or absence of underlying inflammatory diseases., Competing Interests: Declaration of Conflicting Interests The authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Purpose: To compare the efficacy of PPV and ILM peel versus PPV and IFT in patients with traumatic FTMH., Methods: Retrospective interventional comparative case series including two groups of patients with traumatic FTMH. Patients were divided into group I (ILM peel) and group II (IFT). The main outcome measure was closure of the macular hole and restoration of the foveal microstructure. The independent-samples T -test and ANOVA test were used to study the mean between 2 groups and calculate the P value, whereas the bivariate correlation procedure studied the interaction between the variables tested., Results: Group I included 28 patients. Mean preoperative MLD was 757 µ m. Mean preoperative BCVA was approximately 20/320. Group II included 12 patients. Mean preoperative MLD was 529.5 µ m. Mean preoperative BCVA was 20/320. Group I had a macular hole closure rate of 75% versus 92% in group II P =0.05. Mean BCVA improvement was 2.5 lines in group I versus 5 lines in group II P =0.02. Disrupted ELM and IS/OS was the most salient finding in both groups., Conclusion: IFT has a significantly superior anatomic and functional outcome compared to ILM peel in traumatic FTMH.

One new cardenolide, 3-O-β-D-allopyranosylcoroglaucigenin (salsotetragonin) (1), was isolated from the aerial parts of Salsola tetragona Delile with four known cardenolides (2-5); two known flavonoids (6-7), three known phenolic compounds (8-10) and two known fatty acids (11-12). Their structures were identified by spectroscopic analyses and by comparison of their spectral data with those reported in the literature. Compounds 1-5, 7, 10 and 12 were isolated from the genus Salsola for the first time. This is the first report on cardenolides identified in the Amaranthaceae family.
