Terminal deletions of chromosome 3q are associated with a heterogenous clinical phenotype, which includes growth restriction, developmental delay, and intellectual disability. However, little has been published on the ophthalmic impacts of chromosome 3q deletions. We report a 9-year-old boy with a 1.4 megabase deletion of 3q27.1q27.2 whose ocular morbidities included retinal detachment in one eye, vitreous hemorrhage in the other eye, and foveal hypoplasia in both eyes that required acute care and continuous ophthalmologic follow-up., (Published by Elsevier Inc.)

A 60-year-old female with known seropositive rheumatoid arthritis and other co-morbids, presented with right eye hypertensive retinopathy and exudative macroaneurysms. Over the years, she developed vitreous haemorrhage, macula oedema and full thickness macula hole. Fluorescein angiography showed macroaneurysms and ischaemic retinal vasculitis. Initial diagnosis was thought to be hypertensive retinopathy with macroaneurysms and retinal vasculitis secondary to rheumatoid arthritis. Laboratory investigations did not support other causes for macroaneurysms and vasculitis. Hence, delayed diagnosis of IRVAN syndrome was made after detailed review of clinical findings, investigations, and angiographic evidence. Our understanding of IRVAN continues to evolve in the face of challenging presentations. To our knowledge, this is the first reported case of IRVAN associated with rheumatoid arthritis.

Introduction: We present two cases of vitreous hemorrhage after micropulse cyclophotocoagulation one of which had concurrent hyphema. To the best of our knowledge, these are the first cases of vitreous hemorrhage due to micropulse CPC in the United States., Case Description: The first case is an 82-year-old woman with bilateral severe primary open angle glaucoma. BCVA in the right eye was 20/25, and 10-2 Humphrey visual field showed severe peripheral defects. The patient underwent MPCPC of the right eye and at one week, a settled 2 mm hyphema and vitreous hemorrhage confirmed by B-scan were noted. At three months, the patient had a BCVA of 20/80 with an IOP of 12 and retina consultation deferred a PPV. The second case is of a patient with bilateral moderate stage POAG who underwent MPCPC in both eyes. His original VA was 20/200 bilaterally. At 2 weeks, RE VA was count fingers at one foot and LE was 20/150-1. At two months, a RE B scan revealed dense vitreous opacities. Retina consultation revealed vitreous hemorrhage but a PPV was deferred., Conclusion: Clinicians should be aware of the risks of bleeding and the potential need for additional surgical interventions after MPCPC., Competing Interests: Declaration of conflicting interestsThe authors declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: I Albert Khouri, am reporting that I am a consultant to Glaukos, Alcon, and Bausch & Lomb, companies that may be affected by the research reported in the enclosed paper.

Purpose: We describe a case of vitreous haemorrhage and retinal neovascularization secondary to peripheral retinal ischemia associated with disseminated melanoma., Methods: A retrospective case report., Results: A 48-year-old man presented with vitreous haemorrhage in the right eye, peripheral retinal ischemia, and retinal neovascularization in both eyes. CT and MRI scans were suggestive of disseminated malignancy and an ultrasound-guided biopsy of the abdominal mass confirmed metastatic melanoma. Immune checkpoint inhibitor therapy with ipilimumab/nivolumab was initiated. Regarding his ocular status, the vitreous haemorrhage cleared spontaneously, visual acuity improved to 6/7.5 and the patient underwent bilateral peripheral scatter laser photocoagulation to stabilize the retinopathy. The patient passed away 1 year after the initial presentation., Conclusion:  Our patient presented with melanoma and peripheral retinal ischaemia, leading to retinal neovascularization and vitreous haemorrhage. Therefore, melanoma should be considered as a differential diagnosis when investigating the aetiology of peripheral retinal ischaemia.

Purpose: To evaluate the outcomes and prognostic factors of pars plana vitrectomy combined with subretinal injection of recombinant tissue plasminogen activator for submacular hemorrhage (SMH) patients with or without vitreous hemorrhage (VH)., Methods: Sixty-four eyes of 64 patients with SMH underwent pars plana vitrectomy with subretinal injection of recombinant tissue plasminogen activator. Best-corrected visual acuity, SMH displacement, and postoperative complications were analyzed. Predictive factors of the final best-corrected visual acuity were determined using multivariant linear regression., Results: There were 26 eyes with VH and 38 eyes without VH best-corrected visual acuity significantly improved in both VH group (from 2.27 ± 0.40 to 1.25 ± 0.70 logarithm of the minimum angle of resolution) and non-VH group (from 1.76 ± 0.55 to 0.85 ± 0.65 logarithm of the minimum angle of resolution). Complete displacement of SMHs was observed in 47 (73.43%) eyes. Postoperative complications included recurrent SMH (4.69%), recurrent VH (10.94%), rhegmatogenous retinal detachment (3.13%), and epiretinal membrane (4.68%). Treatment-naive condition, early surgery, and younger age were significantly associated with better final best-corrected visual acuity ( B = 0.502, 0.303, and 0.021, respectively, with all P < 0.05)., Conclusion: Pars plana vitrectomy combined with subretinal recombinant tissue plasminogen activator injection is an effective treatment for SMH patients with and without VH.

Purpose: Dense vitreous hemorrhage is a vision-threatening disease with varied clinical manifestations. Herein, we aimed to evaluate its causes and outcomes in patients without diabetes., Methods: A retrospective cohort including 60 eyes from 60 patients with an initial diagnosis of nontraumatic fundus-obscuring dense vitreous hemorrhages and without diabetes was recruited. The relevant medical records from January 2013 to December 2019 were reviewed and analyzed. We classified patients into the following four groups, depending on the underlying cause of dense vitreous hemorrhage: eight cases in the age-related macular degeneration group, four cases in the posterior vitreous detachment group, 20 cases in the tear group, and 28 cases in the vascular group., Results: The most common cause of dense vitreous hemorrhage was retinal vascular obstructive disease (46.7%); the age-related macular degeneration group showed the worst prognosis. The extent of best-corrected visual acuity change was significantly better in patients who underwent vitrectomy compared to those receiving conservative treatment; best-corrected visual acuity change (logarithm of the minimum angle of resolution) was 1.62 ± 0.57 in the surgical group and 1.06 ± 0.88 in the nonsurgical group (Student t-test, p = 0.007)., Conclusions: Retinal vascular disease is the most common cause of vitreous hemorrhages, and surgical treatments have a better visual outcome than nonsurgical treatments.

Purpose: To explore whether varying degrees of vitreous haemorrhage (VH) and calcification act as risk factors for enucleation in patients with advanced retinoblastoma (RB)., Methods: Advanced RB was defined by the international classification of RB (Philadelphia version). Basic information for retinoblastoma patients diagnosed as groups D and E in our hospital between January 2017 and June 2022 was reviewed by logistics regression models. Additionally, a correlation analysis was performed, excluding variables with a VIF (variance inflation factor) >10 from the multivariate analysis., Results: A total of 223 eyes diagnosed with RB were included in assessing VH and calcification; of these, 101 (45.3%) eyes experienced VH, and 182 (76.2%) eyes were found to have calcification within the tumour through computed tomography (CT) or B-scan ultrasonography. Ninety-two eyes (41.3%) were enucleated, of which 67 (72.8%) had VH and 68 (73.9%) calcification, both of which were significantly relevant to enucleation (p < 0.001*). Other clinical risk factors, such as corneal edema, anterior chamber haemorrhage, high intraocular pressure during treatment and iris neovascularization, correlated significantly with enucleation (p < 0.001*). Multivariate analysis included IIRC (intraocular international retinoblastoma classification), VH, calcification and high intraocular pressure during treatment as independent risk factors for enucleation., Conclusions: Despite identifying different potential risk factors for RB, there remains significant controversy concerning which patients require enucleation, and the degree of VH varies. Such eyes need to be evaluated carefully, and management with appropriate adjuvant therapy may improve the outcome of these patients., (© 2023 Acta Ophthalmologica Scandinavica Foundation.

Introduction: Congenital arterial peripapillary loops are rare entities and very few cases are described in literature., Case Description: A 25-year-old Asian man presented a diffuse vitreous hemorrhage in his Left Eye (LE). OCT-A revealed the presence of bilateral vascular loops at the optic nerve head. Fluorescein angiography (FA) confirmed the vascular abnormality in both eyes, with arterial filling in early phases and no dye leakage. At twenty days of follow up, the vitreous hemorrhage in the LE completely reabsorbed and BCVA improved from 20/63 to 20/20., Conclusion: Congenital peripapillary loops should be considered in the differential diagnosis of vitreous hemorrhage, especially in young patients with no history of ocular/head trauma. Multimodal imaging is highly recommended to properly manage the patients, avoiding unnecessary therapeutic choices., Competing Interests: Declaration of conflicting interestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: To report a case with bilateral Terson syndrome presented with a unique mushroom-like mass lesion on the optic disc along with proliferative vitreoretinopathy and tractional retinal detachment., Case Presentation: A 33-year-old man was injured during a traffic accident and had diffuse brain swelling and intraocular hemorrhage. Poor vision in both eyes was noted after the patient regained consciousness. B-scan ultrasonography showed extensive vitreous opacity with a posterior vitreous detachment and without obvious retinal detachment. Vitrectomy was performed in both eyes five months after the accident. After clearing up the vitreous opacity, a peculiar pigmented mushroom-like mass lesion was noted in the posterior pole and had severe adhesion to the underneath optic disc. Extensive multilayered peripapillary epiretinal membrane was found covering the posterior pole and led to tractional retinal detachment around the macula. The mass was presumed to be an organized vitreous hemorrhage originated from the optic disc. The extensive and adherent epiretinal membrane together with the mass lesion were removed as much as possible and silicon oil was injected for tamponade. However, in the right eye, the retina redetached under silicon oil, whereas in the left eye, his vision improved to 20/100., Conclusions: Terson syndrome usually has a favorable prognosis but may be complicated by proliferative vitreoretinopathy and tractional retinal detachment. Careful monitoring is warranted and early vitrectomy should be considered in cases suspecting additional pathologies., (© 2024. The Author(s).)

Acute bilateral vision loss (ABVL) is a rare and challenging diagnostic issue that is most often caused by a neurological disorder. Since it can be the presenting symptom of potentially life-threatening diseases, priority should be given to excluding such diagnoses. Special caution is required if ABVL symptoms result after an intracranial intervention. This article reports on a diagnostic approach for a patient suffering from ABVL due to vitreous hemorrhage related to a subarachnoid hemorrhage (SAH) after endovascular intracranial aneurysm treatment. This case study highlights the importance of imaging interpretation and its consequences., (© 2023.

To investigate the sensitivity and potential application of steady-state flash visual evoked potentials (SSFVEP) in assessing the visual function of fundus diseases with vitreous hemorrhage. 18 patients diagnosed with monocular vitreous hemorrhages in the fundus were examined the flash visual evoked potentials (FVEP) and SSFVEP in both eyes. The difference in the P2-wave amplitude of FVEP and the average amplitude of SSFVEP waveform between the diseased eyes and those without vitreous hemorrhage were statistically compared. There was no significant difference in the waveform of FVEP between both eyes. The amplitude of P2-wave from FVEP of the diseased eye was slightly lower than that without vitreous hemorrhage. However, the difference was not statistically significant (P = 0.111). The waveform of SSFVEP in the eye without vitreous hemorrhage showed a towering shape, while that of the diseased eye was flat. The average amplitude of SSFVEP in the diseased eye was statistically lower than that without vitreous hemorrhage (P = 0.036). The difference ratio of SSFVEP amplitude between both eyes was significantly greater than that of FVEP amplitude (P = 0.028). In some fundus diseases with vitreous hemorrhage, SSFVEP had a higher sensitivity than FVEP, providing a novel potential application for visual function assessment., (© 2024. The Author(s).)

The article presents a clinical case of bilateral Terson syndrome caused by the manifestation of acute myeloid leukemia. A 32-year-old man complained of a sharp decrease in vision in both eyes. Spontaneous subarachnoid hemorrhage occurred secondary to acute myeloid leukemia. Uncorrected visual acuity (UCVA) amounted to OD=0.01, OS=0.005. The anterior segment was normal in both eyes, voluminous immobile white-gray mass measuring 7-9 DD that completely covered the macula (intense hyperechoic cell suspension with a volume of about 1 / 2 of the vitreous cavity, ultrasound B-scan) were visualized in the posterior pole of the vitreous body of both eyes under conditions of maximum drug-induced mydriasis. Diagnosis: vitreous hemorrhage due to subarachnoid hemorrhage in both eyes secondary to acute myeloid leukemia. Vitrectomy was performed in both eyes. UCVA increased to 0.05 in both eyes. Vitrectomy contributed to improvement of visual functions and patient quality of life.

Objective: To establish if the BElfast Retinal Tear and detachment Score (BERT Score) can be used in triaging patients presenting with vitreous haemorrhage to allow safe differentiation between those with retinal tears and detachments, versus haemorrhagic posterior vitreous detachments., Methods: Retrospective audit of 122 patients presenting to eye casualty with vitreous haemorrhage excluding trauma and vascular causes. Twenty-two patients were excluded from the study as they had no follow-up. The BERT Score was applied to the remaining 100 patients., Results: Vitreous haemorrhages with a BERT score ≥4 points were more likely to have a retinal tear or detachment (P = 0.0056). The sensitivity was 84.6% (confidence interval (CI) 65.0-100.0%), specificity 34.5% (CI 24.5-44.5%), positive predictive value 16.2% (CI 7.4-24.9%) and negative predictive value 94% (CI 85.4-100.0%)., Conclusions: The BERT is a reliable scoring system to risk stratify patients with vitreous haemorrhage. Its high sensitivity and negative predictive value can help clinicians to detect high-risk patients., (© 2023. The Author(s), under exclusive licence to The Royal College of Ophthalmologists.)

Purpose: To analyze the outcome of intervention versus observation for vitreous cavity hemorrhage occurring after a 2-month period of blood-free cavity (late postoperative vitreous cavity hemorrhage-POVCH) in eyes operated by vitrectomy for complications of proliferative diabetic retinopathy (PDR)., Methods: This study was a 10-year retrospective, observational, multi-center study involving eight major vitreoretinal surgical centers across India from January 2010 to December 2019. The primary objective of the study was to assess the visual and clinical outcomes of various management approaches for late POVCH. The key secondary objective was to determine the best management option that prevented recurrence. Patients with follow-up of less than 6 months of POVCH management were excluded., Results: The occurrence of late POVCH was studied in 261 eyes. The median time to occurrence was 7 months (range: 2-87) postvitrectomy/silicone oil removal. The majority (58%) experienced a single, nonrecurring POVCH event. Visual acuity outcome was independent of all management approaches (P = 0.179; mean follow-up 20.7 ± 14.1 months). With watchful observation, spontaneous resolution was noted in 83% (60/72 eyes) of eyes in 81.5 days (interquartile range, 169.75). Silicone oil injection was most effective in preventing recurrence (P < 0.001)., Conclusion: The current treatment practice of late POVCH management in PDR suggests that watchful observation for at least 3 months could be as efficacious as any surgical intervention., (Copyright © 2023 Copyright: © 2023 Indian Journal of Ophthalmology.)

Purpose: To evaluate the role of performing photocoagulation up to ora serrata during vitrectomy in preventing recurrent vitreous hemorrhage (VH) in patients undergoing pars plana vitrectomy (PPV) for proliferative diabetic retinopathy (PDR)., Methods: This retrospective, nonrandomized study included 60 eyes from 60 patients who had undergone PPV for VH due to PDR. These patients were divided into two groups: group 1, those who underwent photocoagulation up to ora serrata using the scleral indentation technique during surgery; and group 2, those who did not undergo scleral indentation when photocoagulation and underwent photocoagulation up to vortex veins. Their hospital records were analyzed to investigate the recurrence rate of VH, the time until recurrence of VH after surgery, logarithm of the minimal angle of resolution (logMAR) best-corrected visual acuity (BCVA) measured before surgery and at 1, 2, and 3 years after surgery, and the occurrence of complications such as neovascular glaucoma (NVG) during follow-up., Results: Group 1 exhibited lower recurrence rate of VH (2 of 30 [6.7%] vs. 10 of 30 [33.3%], p = 0.01) and lower occurrence of postoperative NVG (2 of 30 [6.7%] vs. 8 of 30 [26.7%], p = 0.038) compared with group 2. There were no statistically significant differences in logMAR BCVA measured at 1, 2, and 3 years between the two groups (at 1 year: 0.54 ± 0.43 vs. 0.54 ± 0.44, p = 0.954; at 2 years: 0.48 ± 0.47 vs. 0.55 ± 0.64, p = 0.235; at 3 years: 0.51 ± 0.50 vs. 0.61 ± 0.77, p = 0.200). Logistic regression analysis showed that among several factors that could affect recurrence rate of VH, only range of photocoagulation performed was a statistically significant factor (odds ratio, 0.119; 95% confidence interval, 0.022-0.659; p = 0.015)., Conclusions: Photocoagulation treatment over a wider range with scleral indentation could be a beneficial adjunct procedure for preventing postoperative recurrent VH following diabetic vitrectomy.

Purpose: To report a case of mixed cryoglobulinemia manifesting retinopathy with bilateral vitreous hemorrhage (VH) resembling diabetic retinopathy., Case Report: A 60-year-old Japanese man with renal dysfunction of unknown origin was hospitalized for investigation of underlying disease. Laboratory examinations were positive for cryoglobulins composed of IgG and IgM in serum, and hepatitis C virus (HCV) infection. He was diagnosed with HCV-related mixed cryoglobulinemia. During hospitalization, he developed sudden loss of vision and was referred to the department of ophthalmology. Ophthalmic examination revealed VH in both eyes, and vitrectomy was performed on the right eye. Fundus examination after vitrectomy revealed sheathing vessels, mottled hemorrhages in the entire retina, and avascular areas with neovascularization. Disrupted outer retinal layers in the macula were confirmed. Vitreous fluid level of VEGF-A in the right eye was 166.6 pg/mL., Conclusion: Retinal ischemia resembling diabetic retinopathy may cause VH in patients with mixed cryoglobulinemia.

Purpose: To report the outcomes of pars plana vitrectomy for vitreous hemorrhage (VH) associated with retinal vein occlusion and to identify prognostic indicators., Methods: Interventional, retrospective consecutive case series between 2015 and 2021., Results: The study included 138 eyes of 138 patients (64 female and 74 male); 81 patients had branch retinal vein occlusion and 57 had central retinal vein occlusion. The mean age was 69.8 years. The mean duration between the diagnosis of VH and surgery was 79.6 ± 115.3 (range, 1-572) days. The mean follow-up was 27.2 months. The logarithm of the minimum angle of resolution visual acuity significantly improved from 1.95 ± 0.72 (Snellen equivalent, 20/1782) to 0.99 ± 0.87 (20/195) at 6 months and to 1.06 ± 0.96 (20/230) at the final visit (both P < 0.001). The visual acuity at 6 months improved by three or more lines in 103 eyes (75%). Postoperative complications during follow-up included recurrent VH in 16 eyes (12%) (of which 8 eyes underwent reoperations), rhegmatogenous retinal detachment in six eyes (4%), and new neovascular glaucoma in three eyes (2%). Worse final visual acuity was significantly associated with older age ( P = 0.007), concurrent neovascular glaucoma ( P < 0.001), central retinal vein occlusion ( P < 0.001), worse preoperative visual acuity ( P < 0.001), postoperative new neovascular glaucoma ( P = 0.021), and postoperative retinal detachment ( P < 0.001). The duration of VH was not associated with visual outcomes ( P = 0.684). Preoperative antivascular endothelial growth factor injections and tamponade did not prevent postoperative recurrent VH., Conclusion: Pars plana vitrectomy is effective for VH associated with retinal vein occlusion, regardless of the duration of hemorrhage. However, pre-existing risk factors and postoperative sequelae may limit visual recovery.

Background/purpose: To describe diagnostic characteristics and management of exudative macular detachment, a rare complication of pars plana vitrectomy and endolaser for diabetic vitreous hemorrhage., Methods: Case report including multimodal imaging., Results: Forty-seven-year-old man with diabetes mellitus Type 2 and proliferative diabetic retinopathy underwent uncomplicated 23-gauge pars plana vitrectomy, Triesence-assisted hyaloid peeling, fill-in endolaser, and intravitreal bevacizumab injection in the left eye for nonclearing visually significant vitreous hemorrhage. On the first postoperative day, patient developed significant macular subretinal fluid. Multimodal imaging revealed numerous pigment epithelial detachments around optic nerve, and subretinal fluid throughout the macula on optical coherence tomography in the absence of retinal breaks on widefield raster, late deep leakage on fluorescein angiography, and corresponding hyperautofluorescence in the same region. Diagnosed with macular exudative retinal detachment, patient was treated with topical and systemic corticosteroids, with gradual resolution of subretinal fluid and visual acuity improvement., Discussion: Exudative retinal detachment following diabetic pars plana vitrectomy with endolaser has been described in as many as 8.78% of cases, however may be missed in the early postoperative period. Multimodal imaging including multiple pigment epithelial detachments on optical coherence tomography, hyperautofluorescence, and late deep leakage on fluorescein angiography can help differentiate this condition from rhegmatogenous retinal detachment and central serous chorioretinopathy, and guide management to include corticosteroids.

Objective: To report the management and outcomes of vitreous hemorrhage in pediatric patients with X-linked retinoschisis (XLRS)., Materials and Methods: Retrospective case series of pediatric patients with XLRS with vitreous hemorrhage between January 2000 and January 2022 at the Bascom Palmer Eye Institute., Results: Nine patients (12 eyes) met inclusion criteria. The average age at presentation was 5.75 years and mean follow-up time was 6 years. All eyes (58.3%) that underwent fluorescein angiography exhibited peripheral capillary dropout. Six of 12 eyes (50%) were observed without intervention. Four of 12 eyes (33.3%) underwent intravitreal injection of bevacizumab and 2 (16.6%) underwent vitreoretinal surgery. Seven of 12 eyes (58.3%) had documented recurrence of vitreous hemorrhage during follow-up. All retinas were attached and had clear media at final follow-up., Conclusion: Fluorescein angiography is a helpful tool to evaluate the vascular phenotype in XLRS. Favorable anatomic outcomes were noted in this cohort, but recurrence of vitreous hemorrhage was common. [ Ophthalmic Surg Lasers Imaging Retina 2023;54:513-518.] .

Background: Terson syndrome (TS), an intraocular hemorrhage associated with aneurysmal subarachnoid hemorrhage (aSAH), occurs in up to 46% of all patients with subarachnoid hemorrhage. Despite its high incidence, TS is underrepresented in the literature, and patients with aSAH are sometimes not systematically evaluated for the presence of TS in clinical practice. This work aims to raise awareness of TS, reevaluate previous scientific findings, describe risk factors associated with the occurrence of TS, and present our local diagnostic and treatment concept., Methods: All patients with aSAH treated at our institution between October 2010 and May 2020 were included in this retrospective study. The frequency of ophthalmological screening by indirect funduscopy, as well as the results, was investigated. In addition, the collection and statistical analysis of epidemiological and clinical data was performed using χ 2 , Kruskal-Wallis, and analysis of variance testing; multivariate regression; and receiver operating characteristic analysis. The significance level was set at p < 0.05., Results: A total of 617 patients were treated for aSAH in our institution. Of these, 367 patients (59.5%) were ophthalmologically examined for the presence of TS. The rate of TS in the examined patients was 21.3% (n = 78). Patients with TS had significantly higher Fisher and World Federation of Neurosurgical Societies (WFNS) scores (p < 0.0001). Regression analyses showed WFNS grade (p = 0.003) and the occurrence of seizures (p = 0.002) as independent predictors of TS, as did receiver operating characteristic analyses, which had a significant area under the curve of 0.66 for the combination of WFNS grade and seizures. For 12 (15.4%) patients, the TS had to be surgically treated by pars plana vitrectomy in a total of 14 eyes, which resulted in significant improvement of visual function in all patients: mean preoperative best-corrected visual acuity was 0.03 (± 0.08) versus 0.76 (± 0.21) postoperatively (p < 0.001)., Conclusions: TS is a common complication in patients with aSAH, affecting approximately one in five patients. A higher WFNS grade and the occurrence of seizures are associated with TS; therefore, screening for TS should be performed in these patients., (© 2023. The Author(s).)

Objective: To determine the timing of delayed retinal pathology in eyes presenting with acute posterior vitreous detachment (PVD)., Design: Retrospective database study., Subjects: Patients in the Intelligent Research in Sight (IRIS) registry found to have acute PVD based on the International Classification of Diseases, Ninth and Tenth Revision, codes were followed., Methods: Patients coded to have a PVD from 2013 to 2018 along with common procedural technology coding of extended ophthalmoscopy were included. Ocular baseline characteristics included visual acuity, lens status, presence or absence of vitreous hemorrhage, myopia, lattice degeneration, and subspecialty training of the treating physician., Main Outcome Measures: Timing (days) to delayed retinal break or detachment RESULTS: A total of 434 046 eyes met inclusion/exclusion criteria, and 10 518 eyes (2.42%) presented with a delayed retinal break or detachment after initial PVD. The median time to retinal break and detachment after initial PVD was 42 (range, 1-365) days and 51 (range, 1-365) days, respectively. Eyes with vitreous hemorrhage (hazard ratio [HR], 9.30; 95% confidence interval [CI], 8.50-10.2), history of retinal break/retinal detachment in the fellow eye (HR, 3.91; 95% CI, 3.64-4.20), lattice degeneration (HR, 2.61; 95% CI, 2.35-2.90), and myopia (HR, 1.42; 95% CI, 1.33-1.53) were found to be at a higher risk of developing delayed break or detachment., Conclusions: Follow-up examination after initial PVD is necessary to diagnose delayed or missed retinal pathology. In eyes with no initial pathology, providers should consider repeat examination at least once within 6 weeks, and sooner for eyes with higher-risk features., Financial Disclosure(s): Proprietary or commercial disclosure may be found after the references., (Copyright © 2023 American Academy of Ophthalmology.

Purpose: To predict the presence of tractional retinal detachment (TRD) in eyes with dense vitreous hemorrhage (VH) and proliferative diabetic retinopathy (PDR) by evaluating the status of posterior vitreous detachment (PVD) in fellow eyes using optical coherence tomography (OCT)., Methods: A total of 44 eyes from 22 patients who underwent vitrectomy due to dense VH with PDR were enrolled. Using OCT, the PVD status in the fellow eye was divided into two groups (incomplete and complete PVD). The incomplete PVD group included eyes without PVD and eyes with partial PVD. B-scan ultrasonography was performed on eyes with dense VH to evaluate the presence of TRD. Both OCT and B-scan images were reviewed by four ophthalmologists (two novices and two experienced), and the interobserver agreement was evaluated., Results: There was a difference in the interobserver agreement regarding the presence of TRD in eyes with dense VH evaluated by B scan between novice and experienced ophthalmologists (novice, κ = 0.421 vs. experienced, κ = 0.814), although there was no difference between novice and experienced ophthalmologists in the interobserver agreement regarding the status of PVD in the fellow eye evaluated by OCT (novice, κ = 1.000 vs. experienced, κ = 1.000). All observed TRD during vitrectomy occurred in eyes with incomplete PVD in the fellow eye. Logistic regression analysis revealed a statistically significant relation between TRD and the age of the patient (odds ratio [OR], 0.874; p = 0.047), and between TRD and incomplete PVD in the fellow eye evaluated by OCT (OR, 13.904; p = 0.042)., Conclusions: Evaluation of the PVD status in the fellow eye using OCT may be a useful predictor for detecting the presence of TRD in eyes with dense VH and PDR.

Background: Spontaneous hyphema is the rare occurrence of hemorrhage within the anterior chamber of the eye without a predisposing traumatic event. Hyphema can be associated with acute elevations in intraocular pressure in up to 30% of cases, which poses a significant risk for permanent vision loss if not quickly recognized and treated in the emergency department (ED). Anticoagulant and antiplatelet medications have been previously associated with cases of spontaneous hyphema; however, there are limited reports of hyphema with associated acute glaucoma in a patient taking a direct oral anticoagulant. Due to the limited data of reversal therapies for direct oral anticoagulants in intraocular hemorrhage, these patients pose a challenge in deciding whether to reverse anticoagulation in the ED., Case Report: We present a case of a 79-year-old man on apixaban anticoagulation therapy who presented to the ED with spontaneous painful vision loss in the right eye with associated hyphema. Point-of-care ultrasound revealed an associated vitreous hemorrhage, and tonometry was significant for acute glaucoma. As a result, the decision was made to reverse the patient's anticoagulation with four-factor activated prothrombin complex concentrate. Why Should an Emergency Physician Be Aware of This? This case is an example of acute secondary glaucoma due to a hyphema and vitreous hemorrhage. There is limited evidence regarding anticoagulation reversal in this setting. A second site of bleeding was identified by utilization of point-of-care ultrasound, which led to the diagnosis of a vitreous hemorrhage. This allowed for shared decision-making between the emergency physician, ophthalmologist, and patient regarding the risks and potential benefits of the reversal of anticoagulation. Ultimately, the patient decided to have his anticoagulation reversed to try and preserve vision., (Copyright © 2022 Elsevier Inc. All rights reserved.)

Background and Objective: To report the 3-year outcomes for endolaserless vitrectomy with intravitreal aflibercept injection (IAI) monotherapy for proliferative diabetic retinopathy (PDR)-related vitreous hemorrhage (VH)., Materials and Method: Eyes underwent endolaserless vitrectomy and received one preoperative and intraoperative IAI followed by randomization to a q8week or q16week IAI group. Additional IAI was administered as needed., Results: 31/40 eyes were randomized (14 q8week eyes, 17 q16week eyes). Through 152 weeks, q8week and q16week eyes received 18.6 and 12.1 IAI, respectively. Q8week eyes observed a 34 letter visual acuity (VA) increase ( P = 0.003) compared to a 27 letter increase in the q16week group ( P = 0.013)., Conclusions: Endolaserless vitrectomy with aflibercept monotherapy for PDR-related VH provides significant long-term visual gains. Frequent IAI is required for fewer proliferative consequences. [ Ophthalmic Surg Lasers Imaging Retina 2023;54:89-96.] .

Purpose: To investigate late vitreoretinal complications and visual outcomes in patients with regressed retinopathy of prematurity (ROP) with or without prior treatment., Design: International, multicenter, noncomparative retrospective case series., Participants: We analyzed 264 eyes of 238 patients from 13 centers worldwide who developed vitreoretinal complications (retinal detachment [RD], vitreous hemorrhage [VH], or retinal break) ≥ 2 years after resolution of acute ROP., Methods: Each participant was assigned to 1 of 3 groups (the RD, VH, and retinal break groups) according to their primary diagnosis. The average age at presentation, visual acuities, refractive error, axial length, gestational age, birth weight, acute ROP classification, prior treatments for acute ROP, postoperative visual acuity (VA), and concomitant eye conditions in the 3 groups were documented and compared., Main Outcome Measures: Clinical features and visual outcomes of late vitreoretinal complications in patients with regressed ROP., Results: A total of 264 eyes of 238 patients were included. The prior acute ROP status was comparable among the 3 groups, except that the VH group had a higher proportion of patients with type 1 ROP (P = 0.03) and prior treatment (P < 0.001) than the other groups. The average age at presentation was earlier in the RD (20.3 ± 15.5 years) and VH (21.4 ± 18.9 years) groups than in the retinal break group (31.9 ± 18.2 years; P < 0.001). The retinal break group had the best presenting best-corrected VA, followed by the RD and VH groups (P < 0.001). Surgical intervention improved VA in both the RD and VH groups (both P < 0.05). The overall trend of VA was the most favorable in the retinal break group, followed by that in the VH and RD groups. Cicatricial changes in the fellow retina were observed in > 90% of patients with unilateral involvement., Conclusions: Infants with acute ROP remain at a high risk of vision-threatening complications throughout childhood and adulthood. Continual follow-up of patients with ROP is important. When severe complications, such as RD or VH, are detected, timely surgical intervention is necessary to ensure favorable visual outcomes in these patients., (Copyright © 2022 American Academy of Ophthalmology.

Vitreous hemorrhage is associated with a myriad of conditions such as proliferative diabetic retinopathy, proliferative retinopathy following vascular occlusion and vasculitis, trauma, retinal breaks, and posterior vitreous detachment without retinal break. Multiple pathological mechanisms are associated with development of vitreous hemorrhage such as disruption of abnormal vessels, normal vessels, and extension of blood from an adjacent source. The diagnosis of vitreous hemorrhage requires a thorough history taking and clinical examination including investigations such as ultra-sonography, which help decide the appropriate time for intervention. The prognosis of vitreous hemorrhage depends on the underlying cause. Treatment options include observation, laser photo-coagulation, cryotherapy, intravitreal injections of anti-vascular endothelial growth factor, and surgery. Pars plana vitrectomy remains the cornerstone of management. Complications of vitreous hemorrhage include glaucoma (ghost cell glaucoma, hemosiderotic glaucoma), proliferative vitreoretinopathy, and hemosiderosis bulbi.

Purpose: To evaluate clinical features and manifestations of Eales disease and the efficacy of different interventions., Methods: The databases PubMed, EMBASE, and Ovid from inception until February 2021 were searched. Pooled analyses included 1) presenting features, 2) symptoms and signs, and 3) postoperative vision outcomes and complications. Statistical analyses were conducted with R software version 3.6.3., Results: Forty-seven studies involving 3,557 patients and 4,959 eyes were included. The pooling results showed that Eales disease was male dominated (94%), bilateral involvement (64%), and mainly occurred in adolescents. Approximately 83% of patients were positive in Mantoux test, and 31% of patients have vitreous tap polymerase chain reaction positive for tuberculosis genome. More than half of the patients had decreased vision at the first clinic visit. The common signs of Eales disease included sclerotic vessels (83%), neovascularization of retina elsewhere (64%) and periphlebitis (51%). Macular changes could be detected in 24% of patients. The most common complication was vitreous hemorrhage, followed by cataracts and retinal detachment. Photocoagulation was directed at nonperfusion or neovascularization areas, with a decrease in the incidence of later pars plana vitrectomy (19%). Anti-vascular endothelial growth factor treatment was suggested for vitreous hemorrhage, which could achieve high visual acuity improvement rate (82%) while increasing the possibility of retinal detachment (18%). Pars plana vitrectomy was indicated in cases with persistent vitreous hemorrhage or retinal detachment, with 56% of patients obtaining visual improvement. Still, 17% of patients needed a second pars plana vitrectomy, mainly because of recurrent vitreous hemorrhage or retinal detachment., Conclusion: Eales disease most commonly affects young men. It has diverse clinical features, and management should be based on the progression of the disease.

Background and Objective: The purpose of this article is to determine if outcomes in patients presenting with retinal tears with bridging vessels (BVs) differ from those without BVs., Patients and Methods: A case control study of all patients presenting with retinal tears during a 3-year period was completed. Comparisons were made between patients with and without BVs. Variables included vitreous hemorrhage (VH) at presentation, delayed VH, initial and final visual acuity, need for surgery, and retinal detachment., Results: There was a significant increase in the number of patients with a VH at presentation (75% vs 28%; P < .0001), delayed VH (31% vs 7.5%; P = .001), and incidence of pars plana vitrectomy (16% vs 1.3%; P = .002) in the BV cohort. There was no significant difference in time to VH (9.4 vs 38.8 days; P = .32) or final visual acuity (20/25 vs 20/25; P = .45) between the two groups., Conclusions: The presence of a BV is an important prognostic indicator for risk of delayed VH. Documenting the presence of a BV allows for appropriate patient counseling. [ Ophthalmic Surg Lasers Imaging Retina 2022;53:502-505.] .

Purpose: To describe the case of a 12-year-old woman with vitreoretinal manifestations of Type 3 Gaucher disease., Methods: A retrospective case report including multimodal imaging and histologic examination of the vitreous., Results: A 12-year-old woman with a history of Gaucher disease Type 3 was referred to the ophthalmology service for evaluation of vitreous deposits in both eyes. Funduscopic examination was notable for white vitreous opacities in both eyes. Ultra-widefield fluorescein angiography demonstrated areas of blockage associated with the deposits and focal areas of leakage. Optical coherence tomography angiography showed shadow artifact without intrinsic flow at these sites. Three years after presentation, she developed a right hemorrhagic posterior vitreous detachment, requiring pars plana vitrectomy with scleral buckle. A vitreous sample was sent to pathology, which demonstrated Gaucher cells., Conclusion: Gaucher disease is a rare metabolic condition caused by an autosomal recessive deficiency of glucocerebrosidase. To the best of our knowledge, this is the first report of hemorrhagic posterior vitreous detachment in Type 3 Gaucher disease, including ultra-widefield imaging, optical coherence tomography angiography, and histopathology.

Objective: To observe the clinical features, intervention and outcomes of anatomic and visual functions of Terson syndrome in infants, and to explore the appropriate timing for surgery. Methods: This retrospective study included 23 eyes of 14 infants diagnosed with vitreous hemorrhage related to Terson syndrome between May 2008 and March 2021 in Department of Ophthalmology, Peking University People's Hospital. There were 7 males (11 eyes) and 7 females (12 eyes). The age at the initial visit was (4.59±3.96) months. No obvious abnormality was observed in the anterior segment of both eyes of each patient. Data were collected, including demographics, causes of intracranial hemorrhage, characteristics of intraocular hemorrhage, intervention, outcomes of anatomic and visual functions. Results: The causes were craniocerebral trauma in 3 patients, idiopathic cysts in 8 patients, ependymal cyst rupture in 1 patient and respiratory distress in 2 patients. The chief complaint was behavior change in 9 patients, and hemorrhage was found in 5 patients on fundus examination. The rate of complications related to intraocular bleeding was 12/16 when the duration was less than 3 months and 6/7 when the duration was more than 3 months. Twenty eyes (86.96%) were treated by vitrectomy. The follow-up ranged from 6 to 160 months. Three eyes were atrophied, anatomical success was recorded in 18 eyes, and retinal detachment developed in 2 eyes. The visual acuity was improved in 12 eyes (60%), unchanged in 5 eyes (25%), and deteriorated in 3 eyes (15%), except 3 eyes that did not comply with visual acuity examination. Ten eyes showed an obvious myopic shift. Conclusions: The vitreous hemorrhage related to Terson syndrome can occlude the macula and cause severe structural and functional impairments in infants. Vitrectomy is an effective intervention technique, which can quickly remove blood accumulation and restore the anatomical structure, providing better conditions for the visual development of infants.

A 65-year-old male with proliferative diabetic retinopathy (PDR) and non-clearing vitreous hemorrhage underwent 25G pars plana vitrectomy (PPV). A large disk of thick organized blood of 5 disk diameter (DD) size was encountered in subhyaloid space. All attempts including lower cut rates to remove this disk using a 25G cutter turned futile. We used a 20G fragmatome to safely remove this hard clot from vitreous cavity in 50 s. Surgical time for removal of similar clot of 3 DD by 25G cutter in another eye was 5 min. Removal of thick clotted subhyaloid blood by ultrasonic fragmentation during diabetic vitrectomy is a safe, faster, and useful maneuver., Competing Interests: None

Purpose: The purpose of this study was to evaluate the prognostic utility of the degree of vitreous attachment for predicting outcomes of vitrectomy for nonclearing vitreous hemorrhage associated with proliferative diabetic retinopathy., Methods: Medical records of patients who underwent primary vitrectomy for dense nonclearing vitreous hemorrhage secondary to proliferative diabetic retinopathy were examined retrospectively. Eyes were divided into four groups based on the intraoperatively assessed stage of posterior vitreous detachment (PVD), ranging from Stage 0/1 (complete or near-complete vitreoretinal adhesion) to Stage 4 (complete PVD)., Results: Overall, 136 eyes (117 patients) were included. In comparison with eyes with a partial or complete PVD (Stages 2-4), eyes with no PVD (Stage 0/1) had a higher incidence of postoperative hypotony (8%, P = 0.03) and traction retinal detachment (27%, P = 0.002), an increased rate of repeat vitrectomy (49%, P = 0.04), and poorer best-corrected visual acuity at 6 months and 1 year postoperatively (P = 0.04 and P = 0.01, respectively). Presence of a complete PVD at baseline was independently associated with improved postoperative vision at 6 months (P = 0.04)., Conclusion: More extensive vitreoretinal adhesion is associated with higher rates of reoperation and poorer visual outcomes after vitrectomy for dense nonclearing vitreous hemorrhage associated with proliferative diabetic retinopathy. Preoperative determination of PVD status using B-scan ultrasonography may be useful for predicting anatomical and functional outcomes after vitrectomy in these patients.

We present a case of bilateral myelin oligodendrocyte glycoprotein antibody optic neuritis (MOG-ON) with unilateral vitreous hemorrhage in a 6-year-old boy. Multidisciplinary team care, including extensive investigations and prolonged follow-up, excluded alternative causes of vitreous hemorrhage. Early suspicion and diagnosis of MOG-ON led to timely intravenous methylprednisolone treatment, with protracted oral steroid taper, resulting in complete resolution of optic nerve swelling, vitreous hemorrhage, and visual function., (Copyright © 2022 American Association for Pediatric Ophthalmology and Strabismus.

Purpose: This is the first case series of two instances of retinal tears due to an injury sustained while playing pickleball., Methods: Case series., Results: A 66-year old white man presented with a symptomatic retinal tear, localized retinal detachment, and mild vitreous hemorrhage nine days after he was hit in his left eye while playing pickleball. The patient was not wearing eye protection while playing. The patient was treated with cryotherapy, and after three weeks, the vitreous hemorrhage and retinal detachment resolved. In addition, a 60-year-old woman presented with a posterior vitreous detachment and a symptomatic retinal tear 1 month after blunt trauma to her left eye from a pickleball injury. She underwent successful laser retinopexy treatment., Conclusion: Proper eye protection should be strongly considered while playing pickleball, especially in the elderly population or in individuals who are at higher risk for retinal detachment.

Purpose: To compare pars plana vitrectomy (PPV) with combined PPV and scleral buckle (PPV/SB) for repair of primary rhegmatogenous retinal detachment (RRD) with associated vitreous hemorrhage (VH)., Design: Retrospective, observational study., Participants: Patients with RRD and associated VH who underwent PPV or PPV/SB from January 1, 2010, through August 31, 2020, were analyzed., Method: We performed a single-institution, retrospective, observational study of 224 eyes with RRD and VH at the time of detachment. We excluded eyes with <6 months of follow-up, a prior history of retinal detachment (RD) repair with vitrectomy or SB, VH that resolved before surgical intervention, and tractional or combined tractional and rhegmatogenous detachments., Main Outcome Measures: Single-surgery anatomic success (SSAS) at 6 months, defined as no recurrent RD requiring surgical intervention., Results: Pars plana vitrectomy and PPV/SB were performed on 138 eyes (62%) and 85 eyes (38%), respectively. The mean age of the PPV and PPV/SB patients was 61.9 and 60.2 years, respectively. Single-surgery anatomic success was achieved in 107 of 138 eyes (77.5%) that underwent PPV and 78 of 85 eyes (91.7%) that underwent PPV/SB. The difference in SSAS between types of treatment was significant (P = 0.006). Mean visual acuity improvement in the PPV/SB group was 0.54 logMAR units greater than that in the PPV group (P = 0.126). The incidence of postoperative proliferative vitreoretinopathy in the PPV/SB group (11.7%) was lower than that in the PPV group (19.5%; P = 0.128). The rate of repeat PPV for non-RD reasons was similar for both the groups (P = 0.437). Final reattachment status was achieved in 137 of the 138 and 84 of the 85 eyes in the PPV and PPV/SB groups, respectively. Final visual acuity improvement was significantly better in eyes with PPV/SB than in eyes with PPV alone (logMAR 2.12 vs. 1.26, respectively; P = 0.011)., Conclusions: In patients with RRD and VH, SSAS was superior in patients treated with PPV/SB compared with those treated with PPV alone. Although not significantly different, the PPV/SB group had better visual outcomes and a lower postoperative proliferative vitreoretinopathy rate., (Copyright © 2021 American Academy of Ophthalmology.

A 25-year-old man consulted us with a severe exacerbation of pustular psoriasis for 10 days (Figure 1). The patient had pustular psoriasis for the last 12 years. During his hospital stay, he suffered sudden painless and profound loss of vision in both eyes. Subsequently, he was referred to an ophthalmologist. Slit lamp examination of both eyes revealed the presence of a clot in anterior chamber with neovascularization of the iris and the fibrovascular membrane covering the pupil and iris bombe formation nasally and inferiorly (Figure 2a). B-scan ultrasonography showed bilateral vitreous hemorrhage with normal optic nerve head in the right eye and an optic nerve cyst in the left eye (Figure 3). His erythrocyte sedimentation rate was 32.0 mm/hour, while blood and urine screening tests along with review of other systems were found to be normal. The fundi were not visualized due to dense hemorrhage. There was no history of trauma, recent ocular surgery, diabetes, hypertension, hematologic abnormalities, and drug intake known to cause vitreous hemorrhage. Topical medication (eye drop atropine 1%, timolol 0.5%, moxifloxacin and dexamethasone combination) and oral prednisolone (60 mg per day for 2 weeks) were prescribed but were later withdrawn in view of no response and worsening of skin condition. In the past, he had received various treatments, including phototherapy, acitretin, methotrexate, apremilast, cyclosporine, and mycophenolate mofetil; however, his condition was recalcitrant.

Purpose: To evaluate the risk factors for retinal tear (RT) or rhegmatogenous retinal detachment (RRD) associated with acute, symptomatic posterior vitreous detachment (PVD) in a large comprehensive eye care setting., Design: Retrospective cohort study., Participants: A total of 8305 adult patients in the Kaiser Permanente Northern California Healthcare System (KPNC) during calendar year 2018 who met inclusion criteria., Methods: The KPNC electronic medical record was queried to capture acute, symptomatic PVD events. Each chart was reviewed to confirm diagnoses and capture specific data elements from the patient history and ophthalmic examination., Main Outcome Measures: Presence of RT or RRD at initial presentation or within 1 year thereafter., Results: Of 8305 patients who presented with acute PVD symptoms, 448 (5.4%) were diagnosed with RT and 335 (4.0%) were diagnosed with RRD. When considering variables available before examination, blurred vision (odds ratio [OR], 2.7; confidence interval [CI], 2.2-3.3), male sex (OR, 2.1; CI, 1.8-2.5), age < 60 years (OR, 1.8; CI, 1.5-2.1), prior keratorefractive surgery (OR, 1.6; CI, 1.3-2.0), and prior cataract surgery (OR, 1.4; CI, 1.2-1.8) were associated with higher risk of RT or RRD, whereas symptoms of flashes were mildly protective (OR, 0.8; CI, 0.7-0.9). Examination variables associated with a high risk of RT or RRD included vitreous pigment (OR, 57.0; CI, 39.7-81.7), vitreous hemorrhage (OR, 5.9; CI, 4.6-7.5), lattice degeneration (OR, 6.0; CI, 4.7-7.7), and visual acuity worse than 20/40 (OR, 3.0; CI, 2.5-3.7). Late RTs or RRDs occurred in 12.4% of patients who had vitreous hemorrhage, lattice degeneration, or a history of RT or RRD in the fellow eye at initial presentation but only 0.7% of patients without any of these 3 risk factors. Refractive error had an approximately linear relationship with age at presentation of PVD, with myopic patients presenting at a younger age (r = 0.4)., Conclusions: This study, based in a comprehensive eye care setting, found the rate of RT and RRD associated with acute PVD to be lower than rates previously reported by retina subspecialty practices. Several patient features strongly predicted the presence of initial and late complications of acute PVD., (Copyright © 2021 American Academy of Ophthalmology. Published by Elsevier Inc.

Purpose: To determine whether the RETeval electroretinography (ERG) system can be used to evaluate eyes with dense vitreous hemorrhage (VH)., Methods: This retrospective case series study included 69 eyes of 69 patients with acute dense VH. Flicker ERGs were recorded by the RETeval system, an ERG device with adhesive skin electrodes. We evaluated the flicker ERG amplitudes in eyes with VH and the ratio of the VH eye amplitudes compared with the fellow eye amplitudes for each VH cause., Results: In patients with rhegmatogenous retinal detachment, the amplitude ratios were extremely low (0.08 ± 0.03). To detect rhegmatogenous retinal detachment, the area under the receiver operating characteristic curve was 0.977 (95% confidence interval, 0.943-1.000) (best rhegmatogenous retinal detachment cutoff value, 0.14; sensitivity, 100.0%; and specificity, 95.4%). The flicker ERG amplitude was not significantly correlated with the initial visual acuity (ρ = -0.189, P = 0.120) but was positively correlated with the postoperative visual acuity in eyes with VH (ρ = -0.328, P = 0.006)., Conclusion: The RETeval ERG system was found to be a useful diagnostic option in situations where dense VH precluded fundus examination or posterior vitreous detachment was indistinguishable from rhegmatogenous retinal detachment.

Purpose: To report a case of choroideremia characterized by peripheral retinoschisis with vascular abnormalities and vitreous hemorrhage., Observations: A 58-year-old man affected by advanced-stage choroideremia was diagnosed with peripheral retinoschisis in both eyes. Vitreous hemorrhage was present in the right eye with a peculiar clot-like lesion at the periphery. At the 1-year follow-up, the vitreous hemorrhage had reabsorbed and the vascular clot-like lesion in the periphery had almost completely disappeared., Conclusion and Importance: We have reported fundoscopic and OCT features of peripheral-acquired retinoschisis with vascular abnormalities in a patient with choroideremia. OCT examination is extremely useful in clinical evaluation of the peripheral retinal alterations in these cases, where the absence of the retinal pigment epithelium and the choriocapillaris pose many diagnostic difficulties.
