Purpose: This study is to investigate the impact of the coexistence of basic intermittent exotropia and vertical incomitance in the form of the V and sub-V pattern on the results of surgical correction of intermittent exotropia. Methods: The records of 81 pediatric patients who had surgery for intermittent exotropia and a follow-up of more than 1 year were reviewed retrospectively. They were divided into groups: a concomitant group which underwent only horizontal muscle surgery of bilateral lateral rectus recession and a V pattern group which had additional inferior oblique recession, further separated into two subgroups: ≥ 15 prism diopters (classic V pattern group) and ≥ 10 < 15 prism diopters (sub-V pattern group). The surgical outcome, deviation control, stereoacuity, and postoperative drift were assessed after 3 months and 1 year postoperatively. Results: Patients with sub-V and classic V pattern intermittent exotropia showed significantly better surgical success rate (p = 0.025) and less postoperative drift (p = 0.042) than patients without vertical incomitance. One year after surgery, successful surgical outcome was achieved in 83.72% of the vertically incomitant group: 80.76% for the classic V pattern and 88.24% for the sub-V pattern group, while only in 60.53% of nonpattern patients. Conclusions: Patients operated for intermittent exotropia with a coexistent V pattern have consistently better surgical long-term results than those with only horizontal deviation. Additional inferior oblique recessions in the sub V pattern group provided excellent outcomes with no overcorrections; therefore, surgeons should consider addressing vertical incomitance even when the typical criteria for the V pattern are not met.

Introduction: Exotropia-hypotropia complex is an uncommon phenomenon associated with high myopia. However, some literature reports cases of the exotropia-hypotropia complex where residual hypotropia is managed through a secondary surgery following the conventional recession-resection of the lateral rectus (LR) and medial rectus (MR). Nasal Loop myopexy as a primary surgical procedure for the management of exotropia-hypotropia complex has been rarely reported in the literature. Methods: A 24-year-old male with unilateral high myopia presented with a large angle exotropia-hypotropia complex with limitation of elevation in abduction in his left eye. His ocular deviation was successfully managed through a nasal loop myopexy of the superior rectus (SR) and MR using a non-absorbable suture, combined with large LR recession and MR resection. Results: Postoperatively, the patient had satisfactory ocular alignment with improved hypotropia and normal elevation in abduction, contributing to enhanced binocular vision and better cosmesis. Discussion: Managing the exotropia-hypotropia complex in the context of high myopia demands a comprehensive approach that addresses both vertical and horizontal deviations. The surgical strategy employed in this case, which included loop myopexy of SR and MR along with LR recession and MR resection, achieved positive outcomes regarding alignment, elevation, and binocular vision. The case supports variations in muscle path and the potential benefits of tailored surgical strategies for complex strabismus cases associated with high myopia. [ABSTRACT FROM AUTHOR]

Introduction: We previously reported a case of a patient with bilateral congenital cataract identified in the Ogasawara village, Bonin Islands, Japan, on a visit by an ophthalmologist and describe its course over 17 years from initial surgery. Here, we report on a secondary intraocular lens (IOL) implantation that was subsequently performed at 22 years and 5 months of age. Methods: After cataract surgery at 7 months, the aphakic patient began amblyopia treatment using extended-wear soft contact lenses (SCLs). After 10 years of age, SCLs were chosen to achieve crossed monovision considering the cosmetic appearance when facing other people. At 22 years of age, a secondary IOL implantation was performed. Secondary implant in the patient considered appearance and postoperative vision without glasses, we selected the crossed monovision method using a monofocal IOL. The postoperative targeted refraction for the right (non-dominant eye) and left eyes (dominant eye) planed − 0.33D and − 2.25D, respectively. Results: At 3 months after surgery, the corrected distance visual acuity (CDVA) with IOLs for the right and left eyes was 20/16 and 20/60, respectively, and the binocular visual acuity was 20/16 for distant vision and 20/25 for near vision. The CDVA for the right eye was: 20/13 × IOL = sph−0.25D and that for the left eye was: 20/13 × IOL = sph −1.75D D/cyl −0.50D/Ax170°. Although the exotropia was complicated by dissociated horizontal deviation and dissociated vertical deviation, there were no significant changes in ocular position before and after surgery. The patient was satisfied with achieving independence from spectacles and SCLs. Conclusion: The use of the crossed monovision method with monofocal IOLs in this patient and defective binocular function created a visual environment with no inconvenience in everyday life after secondary IOL implantation. In terms of secondary implant after amblyopia treatment, the IOL type or postoperative targeted refraction must be chosen to maintain or improve the visual environment obtained with the amblyopia treatment.

Introduction: Currently, there is no consensus regarding the management of intermittent exotropia (IXT), which includes both surgical and non-surgical treatment options. Nonsurgical management of IXT has been suggested and includes watchful observation, patching, overminus lenses, prism, and vision therapy/orthoptics. While a significant portion of IXT patients are treated by surgery, it is reported that there is a substantial tendency for reoperation or recurrence of IXT. This paper provides a comprehensive review of non-surgical and surgical treatment options for the IXT. Methods: Search strategies involving combination of keywords including intermittent exotropia, divergence excess, basic exotropia, refractive error, glasses, spectacles, natural history, untreated, observe, occlusion, patch, overminus, overcorrecting minus, prism, vision therapy, orthoptic, anti-suppression, fusion exercise, and surgery were used in Medline. All English articles from 01/01/1900 to 01/09/2020 were reviewed. The reference list of the identified articles was also checked for additional relevant articles. Studies focused on animal models or strabismus associated with neurologic disorders or injury were excluded. The following filters were used for surgical management due to the abundance of reports: full text, randomized controlled trial, review, in the last 5 years. Results: Appropriate optical correction of refractive error is generally the starting point for all management approaches, but there is a lack of randomized clinical trial data regarding this treatment modality. Randomized clinical trial data indicate that both observation and occlusion are reasonable management options for children 3–10 years old, and there were insufficient data to recommend occlusion for children 12–35 months old. While overminus lenses were found to improve the control of IXT when assessed wearing overminus spectacles, this improvement did not persist after the treatment ended. The result of the only randomized clinical trial on the effectiveness of base-in prism indicated that this treatment is no more effective than nonprism spectacles for improving control. A recent randomized clinical trial showed that vision therapy/orthoptics is effective in improving the control of IXT when compared to observation alone. Surgery was found to alter a number of clinical characteristics of IXT, including reducing the distance and near angle of deviation, reducing photophobia, improving health-related quality of life, stereopsis, and the Newcastle Control Score. However, there are no randomized clinical trial data comparing surgery with a control group such as placebo or a no treatment observation group. Discussion: Rigorously designed clinical trials to investigate the effectiveness of non-surgical and surgical treatments for intermittent exotropia are needed. [ABSTRACT FROM AUTHOR]

Purpose: To assess the correlation between the contribution rates of fusional convergence from the dominant and non-dominant eye and suppression depth and exotropia control. Study design: Cross-sectional prospective study. Methods: The fusional convergence of 25 participants with intermittent exotropia (mean age 10.8 ± 3.4; range 6–18 years) was measured with an eye-tracking system. The contribution rate was defined based on the amplitude of fusional convergence during refusion relative to the exo-deviation angle. The suppression depth was assessed, and exotropia control was evaluated using the intermittent exotropia Office Control Score. We analyzed the correlations between the contribution rate from the dominant and non-dominant eyes and the suppression depth or control score. Results: There was a negative correlation between the dominant eye's contribution rate and the suppression depth in both eyes (r = −0.85, 95% confidence interval [CI]: −0.97 to − 0.20 in the fixated dominant eye and r = −0.91, 95%CI: −0.95 to − 0.40 in the fixated non-dominant eye). There was a negative correlation between the dominant eye's contribution rate and the control score at a 4-meter distance (r = −0.53, 95%CI: −0.76 to − 0.17). Conclusion: Suppression in intermittent exotropia patients could affect the fusional convergence in the dominant eye. [ABSTRACT FROM AUTHOR]

Background: Microcephaly with or without chorioretinopathy, lymphedema, or mental retardation is a rare autosomal dominant disease caused by mutations in KIF11 which disrupt EG5 protein function, impacting the development and maintenance of retinal and lymphatic structures due to its expression in the retinal photoreceptor cilia. The primary ocular finding in MCLMR is chorioretinopathy. Additional features can include microphthalmia, angle-closure glaucoma, persistent hyperplastic primary vitreous, cataract, pseudo-coloboma, persistent hyaloid artery, and myopic or hypermetropic astigmatism. The appearance of the chorioretinal lesions as white to pinkish, round, non-elevated atrophic areas devoid of blood vessels resembles the lacunae in Aicardy syndrome. Due to the lack of systematic description of the lesions and significant phenotypical variability, there is an impending need for a detailed report of each case. Case presentation: A child with microcephaly detected in the third trimester of gestation began her following in the ophthalmology department due to a non-visually significant cataract. Shortly after, she developed nystagmus and large-angle alternating esotropia with cross-fixation. Her fundus initially showed a pallid optic disc and pigmentary changes, developing thereafter retinal lacunae and a retinal fold. Her differential diagnosis accompanied the dynamic changes in her fundus, which included congenital infections, Leber´s Congenital Amaurosis and Aicardy syndrome. At 19 months old, genetic testing identified a heterozygous mutation (c.1159 C > T, p.Arg387*) in the KIF11 gene. The patient underwent bilateral medial rectus muscle recession surgery at 2 years old for persistent esotropia, with significant improvement. Refraction revealed a hyperopic astigmatism in both eyes (+ 0.25 -2.50 × 180 OD and + 0.75 -2.00 × 170 OS). She continues to require right eye patching for 2 hours daily. Conclusions: This case report expands the phenotypic spectrum of MCLMR by demonstrating a unique combination of retinal features which sheds new light on differential diagnosis from Aicardy syndrome. Our findings emphasize the significant phenotypic variability associated with MCLMR, particularly regarding ocular involvement. This underscores the importance of detailed clinical evaluation and comprehensive reporting of cases to improve our understanding of the disease spectrum and genotype-phenotype correlations.

Introduction : Intermittent exotropia (IXT) is commonly seen in areas with more sunlight, females and Asians. Surgical alignment is recommended to improve binocular function, but a high recurrence rate has been reported. This study aimed to assess the stability of ocular alignment and factors contributing to exodrift post-surgery for IXT over 6-month follow-up.Methods : We retrospectively reviewed the medical records of patients with IXT who underwent unilateral recess resect procedures and attended follow-up examinations for at least six months post-surgery. A significant exodrift was defined as exodrift of more than 10PD at distance and near. Ocular deviation, binocularity, and stereopsis at one and six-month post-operative visits were studied to assess the incidence of exodrift post-surgery and the probable factors causing such drift.Results : Of the 50 patients studied, 26 (52%) were males, 42 (84%) were <20 years. The median age at surgery was 10 years (range 6–14), and the median preoperative angle of deviation was 37 PD. Majority of patients (62%) had exodrift within six months of surgery, and about a quarter of the study population had significant exodrift >10 PD. No clinical factors were found to contribute significantly to exodrift in this study.16 (61.5%) patients attained near and distance BSV post-surgery (p -value: <0.001). Six (12%) and 10 (20%) patients with subnormal near and distance stereopsis, respectively, attained normal stereopsis post-surgery.Conclusion : Over half of the patients operated for IXT had some Exodrift, and one-fourth had significant exodrift within six months post-surgery. Despite improved BSV, many patients failed to attain normal stereopsis with just motor alignment. [ABSTRACT FROM AUTHOR]- Published

Introduction: Dichoptic training has emerged as a promising rehabilitation approach for improving binocular visual function in patients with strabismus. A prospective observational study design was employed to assess the effectiveness of online video game-based dichoptic training in rehabilitating binocular visual function in patients who had undergone an operation for intermittent exotropia. Methods: A total of 64 patients who had undergone an operation for intermittent exotropia were recruited and divided into the training group and the control group based on whether they would receive the dichoptic training. The dichoptic training was conducted for 3 months in the training group and the control group would not accept any form of orthoptic therapy. Assessments of binocular visual functions and deviation were conducted at baseline, 3-month and 6-month follow-up. Results: Twenty-nine participants in the training group (mean 9.69 ± 2.66 years old) and 26 participants in the control group (mean 8.41 ± 2.64 years old) completed follow-up. At both 3- and 6-month follow-ups, the training group showed superior distance stereopsis compared to the control group, with near stereopsis only showing significant difference at the 6-month follow-up. Additionally, the training group exhibited significantly less distance exo-deviation drift than the control group at these times, and no significant difference was observed in near exo-deviation drift between the groups. The control group had a significantly higher rate of suboptimal surgical outcomes at both the 3- and 6-month follow-up. However, no significant differences were observed in simultaneous perception and fusion functions between the two groups. Conclusions: Online video game-based dichoptic training has the potential to become a novel postoperative rehabilitation strategy for patients with intermittent exotropia. [ABSTRACT FROM AUTHOR]

Objective : The aim is to report a very rare case of a fibroblastic tumour in the medial rectus muscle of the right eye in a young adult.Methods : A 28-year-old patient presented to the strabismus clinic with large-angle exotropia in the right eye. The patient had previously undergone strabismus surgery in both eyes, and the old photos showed increasing exotropia from childhood to adulthood. On examination, the patient had a best corrected visual acuity of 20/20, 85 PD of exotropia with a −4 limitation of adduction, and retinal evaluation was unremarkable. In view of the chronicity of the deviation, increasing exotropia over time, and limitation of the ocular motility in adduction, a magnetic resonance imaging was performed.Results : Orbital magnetic resonance imaging (MRI) undertaken to identify the extraocular muscle position revealed a bulky and thickened right medial rectus muscle with post-contrast enhancement and without fat stranding and orbital extension. A muscle biopsy was performed, and a series of histopathological stains revealed that the tumour cells were positive for CD34 and vimentin. Immuno histochemistry and histopathology suggested a benign fibroblastic tumour (superficial CD34+ fibroblastic tumour) with low malignant potential.Conclusion : This report describes a fibroblastic tumour of the eye muscle identified on neuroimaging and confirmed on histopathology. Such a presentation is very rare and to the best of our knowledge has not been previously reported in ophthalmic literature. [ABSTRACT FROM AUTHOR]- Published

Introduction : For decades, the saccadic system has been a favorite target of neurophysiologists seeking to elucidate the neural control of eye movements, partly because saccades are characterized by a set of highly stereotyped relationships between amplitude, duration, and peak velocity. There is a large literature describing the dynamics and trajectories of these movements in normal primates, but there are no similarly detailed analyses for subjects with infantile strabismus syndrome. Previous studies have shown the amplitudes and directions of saccades often differ for the two eyes in this disorder, but it is unknown whether a similar disconjugacy exists for duration. The present study was designed to determine whether or not saccade duration differs for the two eyes in strabismus, and whether there are abnormalities involving the trajectories of these movements.Methods : Dynamic analyses of saccade trajectories and durations were performed for two normal monkeys, two with esotropia and two with exotropia. The amount of curvature was compared for the two eyes. For each monkey with strabismus, the amount of curvature was compared to normal controls. Saccades were placed into 12 bins, based on direction; for each bin, the mean saccade duration was compared for the two eyes (duration disconjugacy). The duration disconjugacy for each bin was then compared for monkeys with strabismus, versus normal control animals.Results : Surprisingly, the amount of curvature was not consistently greater in subjects with pattern strabismus. However, saccade curvature differed for the two eyes by a significantly greater amount for all monkeys with strabismus, compared to normal controls. In addition, for a subset of saccades in subjects with strabismus, saccade duration differed for the two eyes by more than 10 ms, even when the animal was fully alert.Discussion : To the best of the author’s knowledge, this is the first study to show that, in strabismus, saccade durations can differ for the two eyes by an abnormally large amount. These data also suggest that, in monkeys with pattern strabismus, abnormal horizontal-vertical crosstalk in brainstem can lead to directional disconjugacy without significantly impairing component stretching. These results place important constraints on future attempts to model the neural mechanisms that contribute to directional disconjugacy in pattern strabismus. [ABSTRACT FROM AUTHOR]- Published

Background: Four criteria have been proposed for the diagnosis of palindromic rheumatism (PR), including those of Hannonen et al., Passero and Barbieri, Guerne and Weisman, and Gonzalez-López. But none of these criteria has been validated. In this research, we investigated the performance of these diagnostic criteria for diagnosing PR. Methods: In this study, PR and control groups were consecutively recruited from a prospective cohort of intermittent arthritis. Inclusion criteria for PR group were diagnosing PR by an expert rheumatologist, age ≥ 18, having at least 6 months follow-up, and ruling out of other causes of intermittent arthritis. These criteria were applied to both groups. Sensitivity, specificity, positive predictive value, negative predictive value, diagnostic odds ratio (DOR), and Youden's index were calculated for each criteria. Results: This study included 197 consecutive subjects diagnosed with PR and 208 subjects with a diagnosis other than PR. The sensitivity of Hannonen et al. criteria was higher than the Gonzalez-Lopez, Guerne and Weisman, and Pasero and Barbieri criteria (96.4% versus 95.4%, 79.2%, and 35.5%, respectively). The specificity of the Pasero and Barbieri criteria was higher than the other criteria. Hannonen al. criteria with a DOR of 325.7, had the highest DOR. In descending order, the best accuracy belonged to Hannonen et al., Gonzalez-Lopez, Guerne and Weisman, and Pasero and Barbieri criteria (94.3%, 94.1%, 86.4%, and 66.9% respectively). Conclusion: This study showed that the Hannonen et al. and Gonzalez-Lopez criteria have a better performance in diagnosing PR. Key Points • The sensitivity of Hannonen et al. criteria and the specifity of Passero and Barbieri criteria are higher than other proposed criteria for diagnosis of palindromic rheumatism. • Hannonen et al. criteria with a sensitivity of 96.4%, specifity of 92.3% and accuracy of 94.3% has the best performance in diagnosis of palindromic rheumatism between existing diagnostic criteria for palindromic rheumatism.

Background A study to acquire knowledge about the causes, clinical manifestations and management of concomitant exo deviation. Methods This prospective study was conducted in 35 patients at Squint and Neuro ophthalmology department, Institute of Ophthalmology, Government Ophthalmic Hospital, Chennai for a period of 1 year October 2017 to September 2018. Results Maximum number of patients were of age less than 10 years in this study group and majority of patients had exotropia since birth. Constant exotropia was more compared to intermittent exotropia and it was alternating exotropia in majority. Majority of patients presented with an angle of deviation of 20-40 PDs in this study. 80% of patients in this study group required surgery and most among them underwent bilateral lateral rectus recession. Binocular single vision and mean angle of deviation improved after treatment. Conclusions Exodeviations occur less frequently than esodeviations. Majority of exodeviations are present from birth and require surgery . Patients who presented early in age and with less angle of deviation have better chance for restoration of binocular single vision. [ABSTRACT FROM AUTHOR]

Purpose: To compare a single surgeon's surgical outcomes for treating intermittent exotropia using bilateral lateral rectus recession (BLR), unilateral lateral rectus recession and medial rectus resection (RR), and unilateral lateral rectus recession and medial rectus plication (RP). Methods: A retrospective review of all surgeries for basic intermittent exotropia between 2015 and 2023 was performed. Only patients with initial correction using BLR, RR, or RP were included. Exclusion criteria included age older than 18 years, vertical deviation, any nonrefractive ocular diagnoses, prior ocular surgery, and inadequate follow-up. Results: There were 460 patients identified; 123 met inclusion criteria with 54 in the BLR group, 41 in the RR group, and 28 in the RP group. The average pre-operative distance alignment (and standard error) values for the BLR, RR, and RP groups were 25.07 (7.35), 22.44 (5.95), and 23.84 (6.42) prism diopters (PD), respectively. At 1 year, the postoperative distance alignment values for the BLR, RR, and RP groups were 8.72 (7.89), 7.46 (6.31), and 12.83 (6.82) PD, respectively (P =.03). A subanalysis found a significant difference between the BLR and RP (P =.02) and RR and RP (P =.02) groups. There was no difference between the BLR and RR groups (P =.57). Conclusions: This study of three surgical approaches for intermittent exotropia found RP had a significantly larger angle of exodeviation compared to BLR and RR at 1 year of follow-up. Both BLR and RR were equally effective approaches for treating intermittent exotropia. [J Pediatr Ophthalmol Strabismus. 2024;61(4):287–290.] [ABSTRACT FROM AUTHOR]

agmus, optic neuritis, and visual field defects, in patients with MS. They found that these ocular manifestations were associated with specific clinical and demographic characteristics, such as younger age at MS onset and longer disease duration. The study highlights the importance of regular ophthalmic evaluations in patients with MS to detect and manage these ocular complications.The fifth study explored the association between retinal nerve fiber layer (RNFL) thickness and cognitive function in patients with MS. The authors found that thinner RNFL was associated with worse cognitive performance, particularly in processing speed and executive function. The study suggests that RNFL thickness could serve as a potential biomarker for cognitive impairment in MS.Overall, these articles provide valuable insights into various aspects of neuro-ophthalmology, including the diagnosis and treatment of retinal artery occlusion, the shortage of neuro-ophthalmologists, the use of atropine eye drops for myopia progression, the role of S-cones in blue cone monochromacy, the differentiation of sagging eye syndrome and trochlear nerve palsy, the non-specific nature of optic nerve T2-hyperintensity and atrophy in glaucomatous optic neuropathy, the surgical management of spheno-orbital meningiomas, and the risk factors and outcomes of ocular manifestations in MS. These findings can inform clinicians and researchers in their understanding and management of neuro-ophthalmological conditions. [Extracted from the article]

Pyomyositis is a bacterial infection of skeletal muscle leading to abscess formation. Younger males are predominantly involved, but pyomyositis may occur in all ages and sexes. Underlying systemic disease or accompanying immunocompromised states may increase the risk of pyomyositis. This is a report of a 72-year-old, male, with uncontrolled diabetes mellitus, presenting initially as a case of orbital cellulitis. Magnetic resonance imaging confirmed the presence of an abscess in the left lateral rectus. Antibiotic therapy was promptly initiated, and drainage of the abscess was performed via a transconjunctival approach. Pyomyositis resolved post-surgery and medical therapy. Residual exotropia was noted at the eighth month of follow-up necessitating subsequent strabismus surgery. Nine months post-treatment, left lateral rectus pyomyositis did not recur.

Purpose: To assess various aspects of visual function in school children prenatally exposed to opioid maintenance therapy (OMT) and to explore possible outcome differences between prenatal methadone and buprenorphine exposure. Methods: In a cross‐sectional case–control study, 63 children aged 5–13 years with prenatal OMT exposure were compared with 63 age‐ and gender‐matched, non‐exposed controls regarding important visual parameters, such as visual acuity, orthoptic status, refractive state, colour vision, and visual field. Results: The OMT‐exposed children had significantly poorer visual acuity, both for the best eye, the worst eye and binocularly. Two children had mild visual impairment. Manifest strabismus was more frequent in the OMT group, 30%, vs. 4.8% in the control group. The most frequent types of strabismus were accommodative esotropia and intermittent exotropia. Manifest nystagmus was present in 10 (16%) of the exposed children compared to one among the non‐exposed children. The accommodative amplitude was decreased in the OMT group compared to the controls. After adjusting for polydrug exposure and SGA (small‐for‐gestational‐age), the between‐group differences in visual acuity, strabismus, and nystagmus remained. The methadone‐exposed children had poorer visual acuity, increased frequency of strabismus and a higher percentage of nystagmus, hypermetropia and astigmatism compared to the buprenorphine‐exposed children. Conclusions: School‐age children exposed to methadone or buprenorphine in utero had a higher prevalence of strabismus and nystagmus, and a lower visual acuity and accommodation amplitude. Buprenorphine exposure was associated with more favourable results than methadone exposure on most visual outcome measures and should be the preferred substance in OMT. [ABSTRACT FROM AUTHOR]

While horizontal strabismus surgery is generally considered to have favorable outcomes, success rates can vary by type of procedure. Our purpose is to compare the long-term outcomes of patients who underwent one-muscle vs. two-muscle horizontal strabismus surgery. This is a retrospective study comparing one-muscle to two-muscle strabismus surgery for small to moderate angle horizontal strabismus. Demographic data and eye exam parameters were compared at baseline and postoperatively (6 months up to 6 years). Surgical success was defined as a post-operative angle of 10 PD or less. We also compared outcomes by strabismus type: esotropia vs exotropia and adjusted the analysis for previous strabismus surgery. Out of 89 patients with moderate angle horizontal strabismus (25 PD or less), 17 patients had a one-muscle operation, and 72 patients had two-muscle surgery. The mean age was 14.12 ± 9.30 years and 11.70 ± 11.30 years for the one-muscle and two-muscle groups, respectively (p =.74). The baseline characteristics of both groups were comparable. Follow-up time was 32.82 ± 26.93 months in one-muscle and 37.67 ± 23.81 in two-muscle groups (p =.29). Success rate was 70.6% for the one-muscle group and 68.10% for the two-muscle group (p =.69). Outcomes were similar when divided into esotropia and exotropia. The success rate was not affected by previous strabismus surgeries nor by the initial angle of deviation. One-muscle and two-muscle horizontal strabismus surgery had similar long-term outcomes and did not differ by strabismus type nor by angle of deviation. [ABSTRACT FROM AUTHOR]

Purpose: This study aimed to compare the periods for exodrift stabilization and the long‐term surgical outcomes among different surgical methods in intermittent exotropia. Methods: The medical records of 350 patients who had undergone intermittent exotropia correcting surgery [unilateral lateral rectus recession–medial rectus resection (R&R, n = 221), bilateral lateral rectus recession (BLR, n = 51) and unilateral lateral rectus recession (ULR, n = 78)] with a postoperative follow‐up period of 1.5 years or more were retrospectively reviewed. The deviation angles every 6 months after surgery, periods of exodrift stabilization and surgical outcomes were analysed. The period of postoperative exodrift stabilization was defined as when exodrift was no longer significantly different from that at the next visit (p > 0.05). An alignment of 5 PD (prism diopters) esotropia to 10 PD exotropia at a distance and near fixation was considered surgical success. Results: The mean angle of exodeviation was significantly different among surgical procedures at postoperative 1 month (BLR > ULR > R&R, p < 0.001); however, there were no differences among the procedures at 6 months (p = 0.088). The periods of exodrift stabilization were 6 months after ULR, 1 year after BLR and 4.5 years after R&R. The surgical success and reoperation rates did not show significant differences among procedures at the final follow‐up. Conclusion: Patients undergoing R&R showed smaller exodeviation shortly after surgery but required a longer period to stabilize the exodrift. Following ULR, exodeviation was larger in the early postoperative period, but the exodrift was stabilized earlier. Therefore, the long‐term surgical outcomes were similar among ULR, BLR and R&R.

A 63-year-old man with diabetes presented with unilateral ptosis and an exotropia. A diagnosis of isolated diabetic III nerve palsy was made. Subsequent neuro-ophthalmologic evaluation showed multiple cranial nerves involvement consistent with a diagnosis of orbital apex syndrome. Review of past medical history was significant for a previous nasopharyngeal carcinoma, and biopsy of the involved site was consistent with tumor recurrence. This case highlights the importance of correct medical history taking and anatomo-clinical correlation in neuro-ophthalmology. [ABSTRACT FROM AUTHOR]

Purpose: To report a relatively new surgical treatment for near exotropia called medial rectus inferior half plication. Methods: This was a retrospective analysis of the outcomes from a single surgeon performing a plication of the inferior half of the medial rectus muscle in 17 consecutive patients with near exotropia unresponsive to medial rectus bupivacaine injection. Results: Thirteen of 17 (76%) patients were asymptomatic after surgery with no diplopia for near fixation and with either a normal or slightly reduced prism fusion range enabling them to have comfortable binocular single vision. There was one minor surgical overcorrection with distance diplopia that disappeared within 2 weeks of surgery. Of the 4 of 17 (24%) patients who required further intervention, 3 required one further surgical procedure and 1 required an injection of bupivacaine into the contralateral medial rectus muscle to obtain a satisfactory alignment and control of symptoms. No patient needed more than two total operations. Conclusions: The data show medial rectus inferior plication can produce excellent outcomes with minimal risk of overcorrection.

Background: Metastatic colorectal cancer is one of the most common causes of cancer death worldwide, and its incidence increases with age. Treating an older RAS and BRAF wild-type patient represents a challenge for the medical oncologist, even more so for those patients defined as "vulnerable" and undergoing at least two lines of therapy. In this context, recent evidence supports the role of retreatment with anti-EGFR inhibitors and the use of liquid biopsy. However, frequent skin toxicity constitutes a limitation of therapy, especially in older people. Since it has been described that continuous administration of these monoclonal antibodies leads to acquired resistance to anti-EGFRs, with consequent therapeutic failure, an intermittent strategy with chemotherapy plus an anti-EGFR could help maintain the efficacy of the treatment over time, delaying the resistance and improving patients' quality of life. Case presentation: In this case report, we describe the case of an older RAS and BRAF wild-type patient reporting a clinical response after first-line chemotherapy with FOLFOX + panitumumab, subsequently interrupted in the absence of disease progression. After radiological worsening and two additional lines of therapy, the reintroduction of panitumumab plus 5-fluorouracil, administered with a stop-and-go strategy, allowed the patient to benefit from the same drugs for 2 years from diagnosis, to achieve a clinical response during fourth-line treatment lasting more than 3 years, to delay resistance and to avoid unacceptable anti-EGFR skin toxicity. This patient, who died from a myocardial infarction more than 5 years after diagnosis, represents the case of a good synergy between molecular profile of disease and reintroduction of an anti-EGFR with intermittent strategy.

- Abstract
PurposeMethodsResultsConclusionStrabismus is more frequent in cerebral palsy (CP) than in the normal population, but reports differ how much it is increased. We here examined the global prevalence and types of strabismus in CP, whether esotropia or exotropia is more frequent, and whether the prevalence differs between ethnicities and/or country income levels, and between generations.We compiled in a systematic review and meta-analysis the results of 147 CP studies that report the prevalence of strabismus or the ratio of esotropia to exotropia, and we conducted subgroup analyses for region (income level) and ethnicity. We performed a pooled analysis for the CP strabismus prevalence, and estimated the global number of CP cases with strabismus.The pooled prevalence of strabismus in CP is 49.8% in high-income countries and 39.8% in lower-income countries. We estimate the global number of strabismus cases in CP as 12.2 million, with 7.6 million males and 4.6 million females, based on current estimates of 29.6 million global CP cases. Esotropia is more frequent than exotropia in Caucasians, while exotropia is more frequent than esotropia in Hispanic and in some Asian and African populations. The strabismus prevalence in CP increases with increasing country income levels.Generational changes in strabismus prevalence appear to reflect a transition of CP types and an increase in prevalence as countries attain higher income and more effective maternal health care. The distribution of esotropia and exotropia in CP patients largely reflects the horizontal strabismus type that is predominant in the subject’s ethnicity. [ABSTRACT FROM AUTHOR]

MENTAL depression , *HAMILTON Depression Inventory , *EXOTROPIA - Abstract
Theta burst stimulation (TBS) is approved and widely used in the treatment of treatment resistant-major depression. More recently, accelerated protocols delivering multiple treatments per day have been shown to be efficacious and potentially enhance outcomes compared to once daily protocols. Meanwhile, bilateral treatment protocols have also been increasingly tested to enhance outcomes. Here, we examined the efficacy and safety of accelerated bilateral TBS in major depressive disorder (MDD). In this open label pilot study, 25 patients with MDD (60%: women; mean age (SD): 45.24 (12.22)) resistant to at least one antidepressant, received bilateral TBS, consisting of 5 sequential bilateral intermittent TBS (iTBS) (600 pulses) and continuous TBS (cTBS) (600 pulses) treatments delivered to the left and right dorsolateral prefrontal cortex (DLPFC), respectively, daily for 5 days at 120% resting motor threshold. Outcome measures were post-treat treatment changes at day 5 and 2-weeks in Hamilton Depression Rating Scale (HDRS-17) scores and response (≥ 50% reduction from the baseline scores) and remission (≤ 7) rates. There was a significant reduction in HDRS scores at day 5 (p < 0.001) and 2-weeks post treatment (p < 0.001). The response rates increased from 20% at day 5 to 32% at 2-weeks post treatment suggesting delayed clinical effects. However, reduction in symptom scores between two post treatment endpoints was non-significant. 60% of patients could not tolerate the high intensity stimulation. No major adverse events occurred. Open label uncontrolled study with small sample size. These preliminary findings suggest that accelerated bilateral TBS may be clinically effective and safe for treatment resistant depression. Randomized sham-controlled trials are needed to establish the therapeutic role of accelerated bilateral TBS in depression. Trial registration: ClinicalTrials.gov, NCT10001858. [ABSTRACT FROM AUTHOR]

Purpose To compare the efficacy of unilateral recession-resection (RR) versus unilateral recession-plication (RP) in basic-type intermittent exotropia (X (T)). Patients and methods A prospective study included 27 patients, aged 10–45 years with a diagnosis of basic type of X (T), divided into two groups: group I (14 patients) underwent RR and group II (13 patients) underwent RP, follow-up period was 3 months following surgery. Successful outcome defined as postoperative exophoria/exotropia less than 10 Prism diopters (PD) to esophoria/esotropia less than 5 Prism diopters. Results Postoperative, the success rate was 71.43% in group I and 76.92% in group II, without significant difference (P=0.683). Patients with fair and good control of deviation preoperatively had more chances of success than patients with preoperative poor control (OR=12.0, 95% CI=1.482–97.179, P=0.020), other factors including the age, preoperative angle, surgical procedure, errors of refraction had no significant association with successful surgical outcome. Conclusion Both the RR and RP procedures exhibit comparable effectiveness in treating basictype X (T). Plication may be chosen as a substitute tightening technique due to its additional benefits over resection. Poor Preoperative control of deviation decreased the chances of a successful outcome.

Abstract Background Previous studies have shown that children with intermittent exotropia (IXT) have a higher rate of psychiatric abnormalities as they grow up, such as attention deficit. This study explored visual and hearing attention among children with IXT, and evaluated its association with clinical characteristics and cognitive development. Methods Forty-nine children with a diagnosis of IXT and 29 children with traditional development were recruited. The Integrated Visual and Auditory Continuous Performance Test (IVA-CPT) was used to measure the subjects’ full-scale response control quotient (FSRCQ), full-scale attention quotient (FSAQ), auditory response control quotient (ARCQ), auditory attention quotient (AAQ), visual response control quotient (VRCQ), and visual attention quotient (VAQ). The Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV) was used to assess their cognitive function. The differences between the scores of children with IXT and normal controls were analyzed. Results The results showed that the FSRCQ, FSAQ, ARCQ, AAQ, VRCQ, and VAQ of children with IXT were all lower than those of normal controls with the same age (P

Purpose: To report the result of strabismus surgery in eye-salvaged retinoblastoma (Rb) patients. Methods: A retrospective case series including 18 patients with Rb and strabismus who underwent strabismus surgery after completing tumor treatment by a single pediatric ophthalmologist. Results: A total of 18 patients (10 females and 8 males) were included with a mean age of 13.3 ± 3.0 (range, 2–39) months at the time tumor presentation and 6.0 ± 1.5 (range, 4–9) years at the time of strabismus surgery. Ten (56%) patients had unilateral and 8(44%) had bilateral involvement and the most common worse eye tumor's group was D (n = 11), C (n = 4), B (n = 2) and E (n = 1). Macula was involved by the tumors in 12 (67%) patients. The tumors were managed by intravenous chemotherapy (n = 8, 47%), intra-arterial chemotherapy (n = 7, 41%) and both (n = 3, 17%). After complete treatment, the average time to strabismus surgery was 29.9 ± 20.5 (range, 12–84) months. Except for one, visual acuity was equal or less than 1.0 logMAR (≤ 20/200) in the affected eye. Seven (39%) patients had exotropia, 11(61%) had esotropia (P = 0.346) and vertical deviation was found in 8 (48%) cases. The angle of deviation was 42.0 ± 10.4 (range, 30–60) prism diopter (PD) for esotropic and 35.7 ± 7.9 (range, 25–50) PD for exotropic patients (P = 0.32) that after surgery significantly decreased to 8.5 ± 5.3 PD in esotropic cases and 5.9 ± 6.7 PD in exotropic cases (P < 0.001). The mean follow-up after surgery was 15.2 ± 2.0 (range, 10–24) months, in which, 3 (17%) patients needed a second surgery. Conclusion: Strabismus surgery in treated Rb is safe and results of the surgeries are acceptable and close to the general population. There was not associated with tumor recurrence or metastasis.

Background: Pseudo-Brown syndrome is characterized by dysfunction of the superior oblique tendon-trochlear complex. Canine tooth syndrome, which involves superior oblique palsy with pseudo-Brown syndrome, results from damage to the trochlear and superior oblique tendon from dog bites around the eye. This report describes a variant of canine tooth syndrome without pseudo-Brown syndrome following a dog bite around the left upper eyelid. In this case, magnetic resonance imaging (MRI) facilitated early diagnosis and therapeutic intervention. Case Report: A 19-year-old man presented with torsional diplopia following a dog bite around the left upper eyelid and forehead. Five days after the injury, an alternate prism cover test revealed 6 prism diopters (D) exotropia and 5D left hypertropia. Ocular motility showed no significant limitation in elevation or depression during adduction. MRI performed on the same day showed a high-signal area extending from the superior oblique tendon to the trochlear region and the superior oblique muscle belly of the left eye. A diagnosis of canine tooth syndrome without pseudo-Brown syndrome was made and oral steroids were administered. Ocular alignment did not improve, so left inferior oblique myotomy was performed 7 months after the injury. The patient's cyclovertical diplopia resolved postoperatively. Conclusions: Dog bites around the eye can result in abnormalities of the extraocular muscles. Early MRI may be useful for diagnosis and determining treatment strategies. This report has highlighted the importance of rapid assessment and management of patients with dog bites involving the eye. [ABSTRACT FROM AUTHOR]

Background The existing literature does not provide adequate guidance on the diagnosis and management of patients with nonspecific terminal ileitis, while data regarding the percentage of patients who ultimately develop Crohn's disease (CD) are scarce. We evaluated the prevalence and natural course of nonspecific terminal ileitis in patients who underwent colonoscopy during a 11-year period. Methods All patients with endoscopic findings of terminal ileitis and nonspecific histological findings were included. Exclusion criteria were a clinical history of CD or any other disease that can cause terminal ileitis, or a recent history of using drugs implicated in lesions of the terminal ileum. Results From 5353 colonoscopies, 92 patients with nonspecific terminal ileitis were identified (prevalence: 1.7%). Among these patients, 56 (61%) had available follow up for =6 months after the initial endoscopy. Main indications for endoscopy were chronic diarrhea (37.5%), screening endoscopy (23%), and abdominal pain (20%). Sixteen (29%) patients received medical treatment, while recession of symptoms was recorded in 19 of 43 symptomatic patients (44.1%). Twenty-three (41%) of the 56 patients underwent a second endoscopy and 15 (65.2%) cases had persistent endoscopic findings. Eleven (19.6%) of the 56 patients were eventually diagnosed with CD. The probability of CD diagnosis was significantly higher in patients with persistent symptoms (P=0.002) and endoscopic findings at follow up (P=0.038). Conclusions Nonspecific terminal ileitis generally has a benign clinical course. However, patients with persistent symptoms and endoscopic lesions are at increased risk for subsequent development of CD. [ABSTRACT FROM AUTHOR]

- Abstract
Purpose: To evaluate the short‐term (1 week after completion of treatment) effect of office‐based vergence and anti‐suppression therapy (OBVAT) on the Office Control Score when compared to observation alone in children with small‐to‐moderate angle intermittent exotropia (IXT). Methods: In this single‐masked (examiner masked), two‐arm, single‐centre randomised clinical trial, 40 participants, 6 to <18 years of age with untreated IXT, were randomly assigned to OBVAT or observation alone. Participants assigned to therapy received 60 min of OBVAT with home reinforcement once per week for 16 weeks. Therapy included vergence, accommodation and anti‐suppression techniques. The primary outcome measure was the comparison of the distance Office Control Score between the two groups at the primary outcome visit (i.e., 17‐week follow‐up visit). Results: At the primary outcome visit, the OBVAT group (n = 20) had a significantly better distance Office Control Score (adjusted mean difference: −0.9; 95% CI: −0.2 to −1.5; p = 0.008; partial eta squared: 0.19) than the observation group (n = 16). Participants from the OBVAT group were more likely than those from the observation group to have ≥1 point of improvement at the 17‐week visit (OBVAT group: 75%; Observation group: 25%; p = 0.006). Conclusions: In this randomised clinical trial of participants aged 6 to <18 years with IXT, we found that the OBVAT group had a significantly better distance Office Control Score than the observation group at the 17‐week visit. This study provides the first data from a randomised clinical trial demonstrating the effectiveness of OBVAT for improving the control of IXT. Eye care practitioners should consider OBVAT as a viable, non‐surgical treatment option for IXT. A full‐scale randomised clinical trial investigating the long‐term effectiveness of OBVAT in treating IXT is warranted. [ABSTRACT FROM AUTHOR]

Strabismus and Pediatrics Ophthalmology surgeries are pivotal in addressing early-onset visual disorders. An 11-year retrospective study at a tertiary hospital center aimed to elucidate evolving surgical trends, focusing on esotropia cases. The surgical records from January 2009 to January 2020 were analyzed according to the baseline diagnosis. Esotropia cases were evaluated based on the patients' deviation types, surgical techniques, and pre-operative characteristics. A total of 2050 surgeries were performed over the study period. Strabismus surgery accounts for 70% of the department's surgical activity. A trend toward a decrease in esotropia surgeries and a proportional increase in exotropia surgeries was noticeable. Esotropia cases, with a median surgical age of 6 years (p25-p75, 4–10) and uniform gender distribution (females, 54.8%), predominantly involved high angular deviations. Posterior fixation sutures emerged as the preferred surgical technique for esotropia. The study's insights, while aligning with prior European research, introduce new dimensions to the understanding of strabismus surgeries, emphasizing the significance of early interventions, evolving surgical preferences, and the challenges posed by severe deviations.

To evaluate the clinical profile of myopic strabismus fixus (MSF) in children and surgical outcomes of silicone band loop myopexy. We retrospectively reviewed records of children presenting with MSF who underwent silicone band loop myopexy between January 2008 and December 2020 at a tertiary eye care center. Data concerning demographics, refractive error, axial length, extra-ocular motility, and ocular alignment pre-operatively and post-operatively, intra- and post-operative complications, ocular and systemic associations, were evaluated. The long-term effects of band loop myopexy on ocular alignment stability, motility improvement, and myopia progression were analyzed. Surgical outcome was defined as post-operative orthotropia or heterotropia less than or equal to 20 PD. A total of0 eyes of 7 patients (median age: 5 years; 5 boys and 2 girls) who underwent band loop myopexy were included in the study. Among them, three children underwent bilateral and four children underwent unilateral band loop myopexy. Medial rectus recession was performed only in two patients as a part of initial procedure. The median follow-up duration was 7 years. Most of the children, i.e. six of them presented with esotropia-hypotropia and only one patient presented with exotropia-hypotropia complex. The median pre-operative measurements were esotropia of 62.5 PD, hypotropia of5 PD, and exotropia of4 PD. Postoperative average primary position deviation measured was close to 9–10 PD of esotropia. The overall motility improved to −1 from −3. The clinical profile of MSF in children is almost similar to adults. This condition is a rare entity among adults as well as children. Majority of children with MSF presented with esotropia-hypotropia complex. Silicone band loop myopexy with or without medial rectus recession proves to be a reliable surgical procedure as it provides stable outcomes in terms of ocular alignment and motility among children.

This study is to describe the special clinical and genotypic features of a Chinese family with variant types of Duane retraction syndrome and to present our experience on managing these cases. Four individuals from one family were reviewed by ophthalmologic examinations, in which two affected and two unaffected individuals were revealed. MRI scans were performed on the two patients. Relevant gene mutations were screened by the next-generation sequencing technology and confirmed by Sanger sequencing technology. The six-year-old proband presented with special clinical features of severe horizontal gaze dysfunction, exotropia and mild scoliosis. His mother showed significantly limited binocular abductions, with retraction of eyeballs in adduction. From MRI scans, abducens nerves were not observed in both patients and the oculomotor nerve was slightly thin in the proband. The proband and his mother shared the same CHN1 gene mutation site (c. 62A>G; p.Y21C). Strabismus surgery was performed on the proband to correct the primary gaze exotropia. (NM_001822: exon3 or NM_001025201: exon4: c. 62A>G; p.Y21C) A novel CHN1 gene mutation was revealed from a Chinese family with Duane retraction syndrome. Remarkably, the proband and his mother presented different clinical features of ocular motility disorder. Strabismus correction surgery and amblyopia training helped to improve the appearance and visual function of the proband. [ABSTRACT FROM AUTHOR]
