Predicting visual outcomes following anti-vascular endothelial growth factor treatment for diabetic macular edema. Indian J Ophthalmol 2024; 72:S16-S21. [PMID: 38131536 PMCID: PMC10833155 DOI: 10.4103/ijo.ijo_893_23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2023] [Revised: 07/27/2023] [Accepted: 08/01/2023] [Indexed: 12/23/2023] Open
Abstract
PURPOSE To assess the utility of pre-defined imaging biomarkers on optical coherence tomography (OCT) and OCT angiography (OCTA) in patients with diabetic macular edema (DME) following anti-vascular endothelial growth factor (anti-VEGF) therapy in determining visual and anatomical outcomes. METHODS In this prospective, non-randomized, and interventional study, 17 patients with treatment-naive DME were included. OCT biomarkers [size/reflectivity of cysts, disorganization of retinal inner layers, integrity of ellipsoid zone or external limiting membrane, subfoveal serous retinal detachment, hyper-reflective foci (HRF)] and OCTA [vascular density (VD), foveal avascular zone (FAZ), and total micro-aneurysms in superficial capillary plexus and deep capillary plexus (DCP)] were analyzed at baseline and after three monthly intravitreal anti-VEGF injections. Response was defined as a decrease of 10% or more in central macular thickness from the baseline after three injections. RESULTS 13/17 (76.47%) patients were categorized as responders to anti-VEGF therapy. Non-responders had significantly greater hyper-reflectivity of cysts (P = 0.015), larger cystic spaces (P = 0.023), and an increased number of HRF (P = 0.04) at baseline. On OCTA, non-responders showed larger FAZ in DCP (1.35 ± 0.21 versus 1.14 ± 0.28 mm2) (P = 0.042) and lower VD (61.17 ± 0.45 versus 62.73 ± 3.32) in DCP at baseline. At 3 months, the VD increased in responders (63.10 ± 3.42) compared to a decrease in non-responders (60.82 ± 1.13) (P = 0.032). CONCLUSIONS Non-responders show a higher number of micro-aneurysms, larger FAZ, and lower VD in the DCP on OCTA and higher cyst hyper-reflectivity and HRF and larger cystic spaces on OCT imaging.

Abstract
The coronavirus disease 2019 (COVID-19) pandemic caused by the severe acute respiratory syndrome coronavirus 2 was one of the most devastating public health issues in recent decades. The ophthalmology community is as concerned about the COVID-19 pandemic as the global public health community is, as COVID-19 was recognized to affect multiple organs in the human body, including the eyes, early in the course of the outbreak. Ophthalmic manifestations of COVID-19 are highly variable and could range from mild ocular surface abnormalities to potentially sight and life-threatening orbital and neuro-ophthalmic diseases. Furthermore, ophthalmic manifestations may also be the presenting or the only findings in COVID-19 infections. Meanwhile, global vaccination campaigns to attain herd immunity in different populations are the major strategy to mitigate the pandemic. As novel vaccinations against COVID-19 emerged, so were reports on adverse ophthalmic reactions potentially related to such. As the world enters a post-pandemic state where COVID-19 continues to exist and evolve as an endemic globally, the ophthalmology community ought to be aware of and keep abreast of the latest knowledge of ophthalmic associations with COVID-19 and its vaccinations. This review is a summary of the latest literature on the ophthalmic manifestations of COVID-19 and the adverse ophthalmic reactions related to its vaccinations.

Abstract
PURPOSE Clinical registries are increasingly important in research and clinical advancement. This review explores and compares current uveitis registries and recommends future directions on how uveitis registries can complement one another for synergistic effect and benefit. METHODS From a systematic search, 861 citations were screened for longitudinal, non-interventional, and multicenter uveitis-specific registries. Additional registries were identified via consultations with uveitis experts. Characteristics of all registries were analyzed and compared. RESULTS Four registries were identified: Treatment Exit Options for Non-infectious Uveitis, AutoInflammatory Disease Alliance International Registry, Ocular Autoimmune Systemic Inflammatory Infectious Study, and Fight Uveitis Blindness!. Despite certain differences, these registries have the overarching goal of collecting large quantities of real-world, high-quality patient data to improve the understanding of uveitis. CONCLUSION The four uveitis registries share similar goals and collect clinical data from overlapping geographical regions. There is vast potential for collaboration, including data sharing to further augment datasets for analysis.

Abstract
PURPOSE/OBJECTIVE(S) Health-related Quality of life (HRQOL) may be decisive when different treatments yield comparable survival outcomes. We compared QOL in patients undergoing radical cystectomy with ileal conduit (RCIC) or bladder preservation (BP) with (chemo)radiotherapy for bladder cancer. MATERIALS/METHODS Patients with histological diagnosis of bladder cancer, stage T1-T4, N0-N1, M0 with a minimum follow-up of 6 months from the last treatment intervention (RCIC or BP) and alive without disease at the time of QOL assessment were eligible for inclusion. After ethics committee approval, two HRQOL instruments were translated, validated and administered: Bladder cancer index (BCI) for bladder cancer-specific HRQOL, which includes 36 items under three domains - bladder, bowel and sexual function and the EORTC QLQ C30 which includes 30 items under three domains - functional, symptom and global health. The mean QOL scores across various domains and specific questions were compared between the two treatment groups using the independent t-test. RESULTS Of the 104 patients enrolled, 56 had RCIC, and 48 received BP, and included 95 (91.3%) males. The median time from treatment completion to QOL assessment was 22 months (IQR 10-56). The median age for the entire cohort was 62 years (IQR 55-68), 65.5 years (IQR 55-71) in BP and 59.5 years (IQR 55-66) in RCIC. Overall, mean BCI urinary scores and bowel scores were high in both groups, with no significant difference in function or bother subdomains between the two groups (Table 1). Overall, BCI sexual scores were low in both the groups but significantly better after BP (BPmean 56.9, RCICmean 41.5, p = 0.01). Mean scores for sexual function BPmean 38.4 and RCIC mean 25 p (0.07) and sexual bother BPmean 81 RCICmean 62 (p 0.02) subdomains. There was no significant difference in EORTC QOL outcomes in functional (BPmean 91.4, RCICmean 88.7 p 0.23), symptom (BPmean 89.8, RCICmean 89, p = 0.68) and global health scale (BPmean 76.8, RCICmean 78.5, p = 0.69) in both groups. On question-wise assessment, the ability to perform an exercise (BPmean 94.2, RCICmean 85, p = 0.06) and urinary leakage at night time (BPmean 91.7, RCICmean 77.6, p = 0.01) were better in the BP group, while scores for blood in the urine (BPmean 89.1, RCICmean 97, p = 0.05) were better in the RCIC group compared to BP. CONCLUSION Overall, QOL was good in both groups in the urinary and bowel domains while it was low in the sexual domain. However, bladder preservation performed significantly better in the sexual domain than RCIC.

Abstract
INTRODUCTION Ocular toxoplasmosis is the leading cause of posterior uveitis worldwide, affecting individuals acrossdifferent age groups. The key to reducing vision loss includes prompt diagnosis and treatment. However, despite the prevalence of ocular toxoplasmosis, there has been little consensus regarding its pathophysiology,clinical features, diagnosis, and especially management. METHODS The data sources were literature reviews, including Pub Med and Medline databases. Search terms included toxoplasmosis, retinitis, vasculitis, vitritis, uveitis alone or in combination with, serum, aqueous, vitreous eye, ocular and review. RESULTS In this review paper, we have sought to provide an overview of the pathophysiology, epidemiology, and clinical features of the disease, both based on current literature and our own clinical experience. We have also discussed the use of serology, ocular fluid, and ophthalmic investigations that could further facilitate the diagnosis of ocular toxoplasmosis.Different management strategies have been reported worldwide, including newer approaches such as local therapy. CONCLUSION A better understanding of critical aspects of ocular toxoplasmosis will hopefully lead to reduced morbidity, including blindness associated with this condition.

Clin Oncol (R Coll Radiol) 2023; 35:e506-e515. [PMID: 37208232 DOI: 10.1016/j.clon.2023.04.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2023] [Revised: 04/10/2023] [Accepted: 04/28/2023] [Indexed: 05/21/2023]
Abstract
AIMS To assess the efficacy and safety of adjuvant radiotherapy in patients with high-risk muscle-invasive bladder cancer (MIBC) following radical cystectomy (RC) and chemotherapy. MATERIALS AND METHODS The BART (Bladder Adjuvant RadioTherapy) trial is an ongoing multicentric, randomised, phase III trial comparing the efficacy and safety of adjuvant radiotherapy versus observation in patients with high-risk MIBC. The key eligibility criteria include ≥pT3, node-positive (pN+), positive margins and/or nodal yield <10, or, neoadjuvant chemotherapy for cT3/T4/N+ disease. In total, 153 patients will be accrued and randomised, in a 1:1 ratio, to either observation (standard arm) or adjuvant radiotherapy (test arm) following surgery and chemotherapy. Stratification parameters include nodal status (N+ versus N0) and chemotherapy (neoadjuvant chemotherapy versus adjuvant chemotherapy versus no chemotherapy). For patients in the test arm, adjuvant radiotherapy to cystectomy bed and pelvic nodes is planned with intensity-modulated radiotherapy to a dose of 50.4 Gy in 28 fractions using daily image guidance. All patients will follow-up with 3-monthly clinical review and urine cytology for 2 years and subsequently 6 monthly until 5 years, with contrast-enhanced computed tomography abdomen pelvis 6 monthly for 2 years and annually until 5 years. Physician-scored toxicity using Common Terminology Criteria for Adverse Events version 5.0 and patient-reported quality of life using the Functional Assessment of Cancer Therapy - Colorectal questionnaire is recorded pre-treatment and at follow-up. ENDPOINTS AND STATISTICS The primary endpoint is 2-year locoregional recurrence-free survival. The sample size calculation was based on the estimated improvement in 2-year locoregional recurrence-free survival from 70% in the standard arm to 85% in the test arm (hazard ratio 0.45) using 80% statistical power and a two-sided alpha error of 0.05. Secondary endpoints include disease-free survival, overall survival, acute and late toxicity, patterns of failure and quality of life. CONCLUSION The BART trial aims to evaluate whether contemporary radiotherapy after standard-of-care surgery and chemotherapy reduces pelvic recurrences safely and also potentially affects survival in high-risk MIBC.

Abstract
Endogenous endophthalmitis (EE) is an uncommon but potentially devastating ocular infection involving the inner layers of the eye. The global incidence of EE is on the rise. Common ocular signs and symptoms associated with EE include conjunctival injection, ocular pain, and reduced visual acuity. On clinical examination, a history of prior or coexisting systemic infections, symptoms (e.g., fever, malaise), and localizing features may be noted. Clinical diagnosis is often challenging, resulting in critical delays that contribute to a poor prognosis. Blood cultures and ocular fluid samples can aid in conforming causative pathogen(s), after which empirical antibiotic therapy, both systemic and intravitreal, should be instated. The use of steroids to suppress inflammation remains controversial. Surgical options include pars plana vitrectomy. Overall prognosis varies depending on host and pathogen factors, and early diagnosis and initiation of appropriate treatment are crucial.

Prolonged voluntary wheel running reveals unique adaptations in mdx mice treated with microdystrophin constructs ± the nNOS-binding site. Front Physiol 2023; 14:1166206. [PMID: 37435312 PMCID: PMC10330712 DOI: 10.3389/fphys.2023.1166206] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2023] [Accepted: 05/10/2023] [Indexed: 07/13/2023] Open
Abstract
We tested the effects of prolonged voluntary wheel running on the muscle function of mdx mice treated with one of two different microdystrophin constructs. At 7 weeks of age mdx mice were injected with a single dose of AAV9-CK8-microdystrophin with (gene therapy 1, GT1) or without (gene therapy 2, GT2) the nNOS-binding domain and were assigned to one of four gene therapy treated groups: mdxRGT1 (run, GT1), mdxGT1 (no run, GT1), or mdxRGT2 (run,GT2), mdxGT2 (no run, GT2). There were two mdx untreated groups injected with excipient: mdxR (run, no gene therapy) and mdx (no run, no gene therapy). A third no treatment group, Wildtype (WT) received no injection and did not run. mdxRGT1, mdxRGT2 and mdxR performed voluntary wheel running for 52 weeks; WT and remaining mdx groups were cage active. Robust expression of microdystrophin occurred in diaphragm, quadriceps, and heart muscles of all treated mice. Dystrophic muscle pathology was high in diaphragms of non-treated mdx and mdxR mice and improved in all treated groups. Endurance capacity was rescued by both voluntary wheel running and gene therapy alone, but their combination was most beneficial. All treated groups increased in vivo plantarflexor torque over both mdx and mdxR mice. mdx and mdxR mice displayed ∼3-fold lower diaphragm force and power compared to WT values. Treated groups demonstrated partial improvements in diaphragm force and power, with mdxRGT2 mice experiencing the greatest improvement at ∼60% of WT values. Evaluation of oxidative red quadriceps fibers revealed the greatest improvements in mitochondrial respiration in mdxRGT1 mice, reaching WT levels. Interestingly, mdxGT2 mice displayed diaphragm mitochondrial respiration values similar to WT but mdxRGT2 animals showed relative decreases compared to the no run group. Collectively, these data demonstrate that either microdystrophin construct combined with voluntary wheel running increased in vivo maximal muscle strength, power, and endurance. However, these data also highlighted important differences between the two microdystrophin constructs. GT1, with the nNOS-binding site, improved more markers of exercise-driven adaptations in metabolic enzyme activity of limb muscles, while GT2, without the nNOS-binding site, demonstrated greater protection of diaphragm strength after chronic voluntary endurance exercise but decreased mitochondrial respiration in the context of running.

Genotypic capacity of post-anthesis stem reserve mobilization in wheat for yield sustainability under drought and heat stress in the subtropical region. Front Genet 2023; 14:1180941. [PMID: 37408776 PMCID: PMC10318140 DOI: 10.3389/fgene.2023.1180941] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2023] [Accepted: 05/23/2023] [Indexed: 07/07/2023] Open
Abstract
Wheat productivity is severely affected by drought and heat stress conditions worldwide. Currently, stem reserve mobilization (SRM) is receiving increased attention as a trait that can sustain wheat yields under adverse environments. However, the significance of SRM in sustaining wheat yields under drought and heat stress conditions remains uncertain in the tropical climate of Indo-Gangetic Plain region. Therefore, this study aimed to investigate genotypic variations in SRM in wheat and their influence on yield sustainability under drought and heat stress environments. The experiment was designed in an alpha-lattice layout, accommodating 43 genotypes under four simulated environments [timely sown and well irrigated (non-stress); timely sown and water-deficit/drought stress; late-sown and well-irrigated crop facing terminally high temperature; and late-sown and water-deficit stress (both water-deficit and heat stress)]. The water-deficit stress significantly increased SRM (16%-68%, p < 0.01) compared to the non-stress environment, while the heat stress conditions reduced SRM (12%-18%). Both SRM and stem reserve mobilization efficiency exhibited positive correlations with grain weight (grain weight spike-1) under all three different stress treatments (p < 0.05). Strong positive correlations between stem weight (at 12 days after anthesis) and grain weight were observed across the environments (p < 0.001); however, a significant positive correlation between stem weight and SRM was observed only with stress treatments. Results revealed that the SRM trait could effectively alleviate the impacts of water-deficit stress on yields. However, the SRM-mediated yield protection was uncertain under heat stress and combined water-deficit and heat stress treatments, possibly due to sink inefficiencies caused by high temperature during the reproductive period. Defoliated plants exhibited higher SRM than non-defoliated plants, with the highest increment observed in the non-stress treatment compared to all the stress treatments. Results revealed that wider genetic variability exists for the SRM trait, which could be used to improve wheat yield under drought stress conditions.

Abstract
PURPOSE To describe clinical and imaging findings in a young boy presenting with bilateral rapidly progressive necrotizing macular retinitis. METHODS A 12-year-old Asian Indian boy developed bilateral progressive macular retinitis. He had generalized tonic-clonic seizures for the past 3 months and gave a history of poor scholastic performance with dementia of recent onset. Multimodal imaging comprising and detailed systemic and laboratory work-up was performed. RESULTS Both eyes showed rapidly progressive full-thickness retinitis lesions observed as disruption of retinal architecture in both eyes. Left eye optical coherence tomography shows full-thickness retinal involvement with sparing of the internal limiting membrane. Electroencephalogram and magnetic resonance imaging (brain) were suggestive of subacute sclerosing panencephalitis and the diagnosis was confirmed by elevated cerebrospinal fluid and serum IgG measles. The patient did not survive despite treatment with systemic interferon therapy. CONCLUSION It is important to look for the measles virus as a probable cause of necrotizing retinitis and neurologic symptoms in immunocompetent unvaccinated young patients. Early referral to a neurologist may assist in the early diagnosis of subacute sclerosing panencephalitis and targeted therapy.

Characterizing the metabolomic signature of attention-deficit hyperactivity disorder in twins. Neuropharmacology 2023; 234:109562.

Abstract
Emerging evidence implicate the gut microbiota as a potential susceptibility factor in attention-deficit hyperactivity disorder (ADHD), a common multifactorial neurodevelopmental condition. However, little is known about the biochemical signature of ADHD, including the metabolic contribution of the microbiota via the gut-brain axis, and the relative contribution of genetics and environmental factors. Here, we perform unbiased metabolomic profiling of urine and fecal samples collected from a well-characterized Swedish twin cohort enriched for ADHD (33 ADHD, 79 non-ADHD), using 1H nuclear magnetic resonance spectroscopy and liquid chromatography-mass spectrometry. Our results highlight sex-specific patterns in the metabolic phenotype of individuals with ADHD. Specifically, the urine profile of males, but not females, with ADHD was characterized by greater excretion of hippurate, a product of microbial-host co-metabolism that can cross the blood-brain-barrier with bioactivity of potential relevance to ADHD. This trans-genomic metabolite was also negatively correlated with IQ in males and was significantly correlated with fecal metabolites associated with gut microbial metabolism. The fecal profile of ADHD individuals was characterized by increased excretion of stearoyl-linoleoyl-glycerol, 3,7-dimethylurate, and FAD and lower amounts of glycerol 3-phosphate, thymine, 2(1H)-quinolinone, aspartate, xanthine, hypoxanthine, and orotate. These changes were independent of ADHD medication, age, and BMI. Furthermore, our specific twins' models revealed that many of these gut metabolites had a stronger genetic influence than environmental. These findings suggest that metabolic disturbances in ADHD, involving combined gut microbial and host metabolic processes, may largely derive from gene variants previously linked to behavioral symptoms in this disorder.

Abstract
INTRODUCTION Proton beam therapy has been utilised for the treatment of uveal melanoma in the UK for over 30 years, undertaken under a single centre. In the UK, all ocular tumours are treated at one of four centres. We aimed to understand the variation in referral patterns to the UK proton service, capturing all uveal melanoma patients treated with this modality. METHODS Retrospective analysis of data regarding all patients treated at the Clatterbridge Proton service between January 2004 and December 2014. RESULTS A total of 1084 patients with uveal melanoma were treated. The mean age was 57 years (range 9-90 years), basal diameter of 11.5 mm (range 2.0-23.4 mm) and tumour thickness of 3.9 mm (range 0.1-15.4 mm). The majority were TNM stage I (39%) or II (36%). The distance to the optic nerve varied from 0 to 24.5 mm with 148 (14%) of patients having ciliary body involvement. There were variations in the phenotypic characteristic of the tumours treated with protons from different centres, with London referring predominantly small tumours at the posterior pole, Glasgow referring large tumours often at the ciliary body and Liverpool sending a mix of these groups. DISCUSSION In the UK, common indications for the use of proton treatment in uveal melanoma include small tumours in the posterior pole poorly accessible for plaque treatment (adjacent to the disc), tumours at the posterior pole affecting the fovea and large anterior tumours traditionally too large for brachytherapy. This is the first UK-wide audit enabling the capture of all patients treated at the single proton centre.

Abstract
Immunoglobulin A nephropathy (IgAN) is a rare but important systemic disease with or without ocular manifestations. We describe 4 cases of IgAN presenting with scleritis and review the various ocular manifestations in patients with IgAN. We found 55 cases with ocular manifestations in patients with prior or newly-diagnosed IgAN described in 38 publications. The most common ocular manifestations of IgAN were episcleritis (23.6%), scleritis (16.4%), hypertensive retinopathy or retinal vasculopathy (20.0%), and uveitis (14.5%). The median age at presentation was 36.5 years, with 54.5% female patients. 61.8% had history of IgAN prior to ocular involvement, while 29.1% had ocular presentations as the first manifestation of IgAN. The majority received systemic corticosteroids and/or immunosuppressants. Additionally, we report 4 women with anterior scleritis and previous diagnosis of IgAN. All 4 were treated with topical and systemic corticosteroids. Three out of 4 patients had no recurrence for at least 1 year since the first presentation. IgAN is a rare but important systemic association to be considered in ocular inflammatory conditions. Timely recognition and comanagement of the disease with nephrologist could reduce disease morbidity.

Abstract
AIM To analyze the structural features and therapeutic response in clinical and subclinical inflammatory choroidal neovascularization (i-CNV) detected inside subretinal hyperreflective material (SHRM) using swept-source optical coherence tomography (SS-OCT) and SS-OCT angiography (SS-OCTA). METHODS In this prospective interventional study, subjects with quiescent posterior uveitis presenting with SHRM on SS-OCT and CNV network on SS-OCTA were included. Subjects with intraretinal fluid/subretinal fluid (IRF/SRF) received intravitreal antivascular endothelial growth factor (anti-VEGF) injections, while those with no IRF/SRF either received treatment or observation for 6 months until they developed IRF/SRF or decrease in best-corrected visual acuity (BCVA)/metamorphopsia. Serial comparisons included SHRM width and height and intrinsic flow signal on OCTA. RESULTS 28 eyes of 22 subjects (12 males; mean age: 29.52 ± 12.56 years) were evaluated. Subjects with IRF/SRF at baseline (n = 6 eyes; termed as exudative iCNVs) receiving treatment showed significant improvement in BCVA (p = .017), SHRM width/height and flow signal (p < .05). Among eyes with no IRF/SRF (n = 22; termed as non-exudative iCNVs), 7 received treatment and showed significant improvement in SHRM parameters and BCVA (p < .05). 4/15(26.67%) eyes that received no treatment developed IRF/SRF upon 6-month follow-up. CONCLUSION SHRM may act as a useful biomarker to monitor activity and response to therapy in eyes with iCNV.

Abstract
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.

Abstract
Till today, ocular tuberculosis (OTB) presents clinicians with significant challenges in diagnosis and management. There is no one-size-fits-all approach to a heterogeneous disease like OTB, and clinicians often have to consider a multitude of factors when initiating treatment, such as tuberculosis endemicity, the probability of a true OTB diagnosis in the setting of nonspecific ocular features, the effective duration of treatment, and the likelihood of vision-threatening complications in the patient. It is no wonder that treatment protocols are widely varied globally. There have been recent developments in the standardization of nomenclature and therapeutic strategies for OTB, as established by the Collaborative OTB Study Working Group. In this review, we referred to findings in retrospective studies, international clinical guidelines, and OTB consortiums, to explore the clinical presentations, investigations, and updated management principles for patients with presumed tubercular uveitis.

Abstract
Abstract
Introduction
Incisional Hernia has an incidence ranging from 2–20%. Large and complex incisional hernias are difficult to treat with standard procedures. PCS-TAR is a relatively novel procedure. There persists a gap in knowledge regarding its outcomes, especially in the Indian population.
Aims & Objective
To identify the pre-operative clinical and radiological factors that predict the risk of re-herniation and wound and mesh-related complications after CVH (Complex Ventral Hernia)
Methodology
In a prospective observational study, patients undergoing open PCS-TAR with retro rectus mesh for Complex Ventral Hernia repair included in the study. The patient demographics, hernia characteristics, radiological details, operative data, post- operative outcomes, and follow-up data were entered in a pre-designed proforma. Data were analyzed with SPSS softwere.
Results
35 patients with CVH were included, of which 30 (85%) women and 5 men. The mean age was 51.8 years and the mean BMI was 29.7 kg/m2. The mean size of defect was 12 cm. 83% hernia were midline primary and 255 were recurrent hernias. We observed zero recurrences at six months of follow-up, but a high wound morbidity rate of up to 49%, of which most common was seroma formation. 23% of patients developed SSI.
Conclusion
In conclusion, PCS-TAR is a promising novel procedure for complex ventral hernias not amenable to primary closure using the traditional retro rectus approach, with excellent short term outcomes. Wound morbidity is a significant concern with this procedure, which can be prevented or reduced by thorough pre-operative optimization on a case-to-case basis.

Abstract
Purpose To analyze the structural features of subretinal hyper-reflective material (SHRM) in posterior uveitis using swept-source optical coherence tomography (SS-OCT) and optical coherence tomography angiography (SS-OCTA). Methods In this observational study, subjects with quiescent posterior uveitis and the presence of SHRM on SS-OCT were subjected to SS-OCTA to identify the presence of an intrinsic choroidal neovascular (CNV) network. OCT features were compared for SHRM harboring CNV (vascular SHRM) with those without CNV network (avascular SHRM) to identify clinical signs pointing toward the presence of CNVM inside SHRM. Results Forty-two eyes of 33 subjects (18 males; mean age: 29.52 ± 12.56 years) were evaluated. Two-thirds (28/42) of eyes having SHRM on SS-OCT harbored intrinsic neovascular network (vascular SHRM). Increased reflectivity of SHRM (P < 0.001) and increased transmission of OCT signal underlying SHRM (P = 0.03) were suggestive of the absence of CNVM. The presence of intra/subretinal fluid (P = 0.08) and pitchfork sign (P = 0.017) were important markers of vascular SHRM. Conclusion SHRM is an important OCT finding in eyes with posterior uveitis. Meticulous assessment of SHRM characteristics on SS-OCT can aid in identifying the underlying intrinsic neovascular network.

Abstract
Abstract
Introduction
Pancreatic cancer and cholangiocarcinoma including, cancer of ampulla of Vater, are very aggressive and have a dismal prognosis; hence improved methods of patient stratification are required.
Methods
We assessed the expression of CD10 in stromal and epithelial cells of two patient cohorts using immunohistochemistry on tissue microarrays. The first cohort was composed of 68 pancreatic adenocarcinomas and the second cohort was composed of 120 cancers of the bile duct and ampulla.
Results
In bile duct and ampullary carcinomas an association was observed between CD10 stromal expression and patient age (p =0.009). The CD10 stromal expression was associated with poor disease specific survival (DSS) (p =0.05). In multivariate Cox model for DSS, stromal CD10 expression (p = 0.037) was independently associated with poor outcome. In multivariate Cox model for disease free survival (DFS), CD10 stromal expression (p = 0.012), and nodal status (p = 0.025) were independently associated with poor outcome. In pancreatic cancer, no statistically significant association was observed between CD 10 stromal expression and clinicopathological variables such as tumour size (p = 0.099), T stage (p = 0.393), N stage (p = 0.860), Vascular invasion (p = 0.904), perineural invasion (p = 0.532) and grade (0.168). In multivariate Cox model for DSS, T stage (p = 0.042) was independently associated with poor outcome.
Conclusion
The results suggest that CD10 stromal expression may have prognostic significance in cholangiocarcinoma. The findings of this study warrant a larger follow-up study.
Take-home message
The results suggest that CD10 stromal expression may have prognostic significance in cholangiocarcinoma. The findings of this study warrant a larger follow-up study.

Abstract
PURPOSE To describe a novel clinical and imaging finding in patients with tubercular posterior uveitis. METHODS A retrospective review of 3 cases presented at a tertiary referral eye centre in North India was performed between June 2016 and March 2019. All the patients had received an initial diagnosis of noninfective etiologies (sympathetic ophthalmia, necrotizing scleritis, and lymphoma). Fundus photography, fluorescein angiography, fundus autofluorescence, and enhanced-depth imaging optical coherence tomography were reviewed. RESULTS Three patients (all Asian Indian women: aged 18, 49, and 52 years) diagnosed with panuveitis were investigated for various etiologies based on the initial clinical suspicion. During the course of therapy, all the patients developed peripheral yellow subretinal pigment epithelium deposits (YSRPE) which appeared hypoautofluorescent on fundus autofluorescence and initially hypofluorescent with late hyperfluorescence on fluorescein angiography. The patients were subjected to detailed systemic evaluation and laboratory tests. All the patients showed acid-fast bacilli on invasive tissue biopsies. After initiation of antitubercular therapy, the lesions resolved in all eyes. CONCLUSION Yellow subretinal pigment epithelium deposits represent a novel and important diagnostic sign of tubercular posterior uveitis.

Abstract
Purpose: The COVID-19 pandemic has brought medical and surgical training to a standstill across the medical sub-specialties. Closure of outpatient services and postponement of elective surgical procedures have dried up opportunities for training vitreoretinal trainees across the country. This “loss” has adversely impacted trainees’ morale and mental health, leading to feelings of uncertainty and anxiety. Therefore, there is an urgent need to redraw the surgical training program. We aimed to describe a systematic stepwise approach to vitreoretinal surgical training. Methods: We introduced a three-pronged approach to vitreoretinal surgical training comprising learn from home, wet lab and simulator training, and hands-on transfer of surgical skills in the operating room in our institute. Results: Encouraging results were obtained as evaluated by feedback from the trainees about the usefulness of this three-pronged approach in developing surgical skills and building their confidence. Conclusion: The disruption caused by the COVID-19 global pandemic should be used as an opportunity to evolve and reformulate surgical training programs to produce competent vitreoretinal surgeons of the future.

Abstract
Purpose To report recurrence of tubercular choroiditis following anti-SARS-CoV-2 vaccination in two patients with quiescent disease activity for more than a year. Methods Retrospective observational case reports. Results Two patients (one female and one male) under follow-up for posterior uveitis having stable course with absence of ocular inflammation for more than a year presented with recurrence of choroiditis lesions 2–6 weeks following anti-SARS-CoV-2 vaccination. Both the patients were managed with intravitreal dexamethasone implant (Ozurdex®, Allergan, Inc., Irvine, CA, USA) and showed resolution of choroiditis lesions upon follow-up. Conclusions Acute onset recurrence of inflammation, in absence of any change in health status or treatment suggests the potential role of vaccination being the trigger of this reactivation. Given large-scale vaccination against novel coronavirus- SARS-CoV-2, careful vigilance is warranted to pick up the disease recurrence in patients with posterior uveitis.

Abstract
PURPOSE To describe a young male with bilateral sequential Cytomegalovirus retinitis (CMVR) as the presenting feature of Dyskeratosis Congenita. CASE REPORT A 25-year-old human immunodeficiency virus (HIV) negative male developed CMVR in his left eye, while on a three week course of oral valganciclovir therapy for CMV retinitis in his right eye. Systemic examination revealed reticular hypopigmentation of the forearms, dystrophic nails, oral leukoplakia and complete blood counts showed pancytopenia. A diagnosis of Dyskeratosis Congenita was confirmed with genetic testing. CONCLUSION CMVR in non-HIV individuals should be considered as a harbinger of systemic immunosuppressive conditions. Ophthalmologists may be the first ones to suspect and diagnose congenital immunosuppressive disorders like Dyskeratosis Congenita in these patients.

Abstract
Abstract
Introduction
Oesophageal gastro-intestinal stromal tumours (GISTs) are rare, accounting for less than five percent of all GIST, with the majority of these occurring at the oesophago-gastric junction (OGJ). Due to the anatomical location and size of these tumours at presentation, surgical resection is often a major undertaking.
Neoadjuvant treatment with tyrosine kinase inhibitors, such as Imatinib mesylate, have the potential to downstage such tumours, thereby limiting the extent of subsequent surgical resection. This may therefore reduce any potentially associated morbidity and mortality.
Case Description
We report the case of a 75-year-old gentleman who presented with a large OGJ GIST, which presented with dysphagia. The tumour was deemed too large for local excision due to the risk of compromising the lumen at the OGJ in attempting to obtain a clear resection margin. Given the patient’s co-morbidity, oesophagectomy or total gastrectomy was deemed too major an undertaking. Therefore, endoscopic biopsies were obtained with a view to possible neoadjuvant therapy. These confirmed DOG-1 and Exon-11 mutations, suggesting sensitivity to Imatinib mesylate. A standard dose regime of 400mg daily for a planned 36-month course was commenced. Subsequent imaging showed a substantial decrease in tumour bulk and the decision was made to perform a local excision. A local enucleation procedure was performed, and the patient made a sound recovery.
Post-operative histology of resected tumour showed almost complete tumour regression.
Discussion
This significant response to neoadjuvant Imatinib mesylate therapy demonstrates clear potential for its use in similar cases, where radical resection would cause significant morbidity and risk mortality.

Abstract
PURPOSE To study the frequency of intrauterine rubella infection in a cohort of neonatal-onset glaucoma and its effect on the treatment outcomes. MATERIAL AND METHODS Infants with neonatal-onset glaucoma presenting to the pediatric glaucoma service at a tertiary care centre in northern India at Chandigarh between 1st January and 30th September 2018 with a minimum postoperative follow-up of one year were included in this study. Rubella-IgM antibodies were tested in all patients. Surgery for intraocular pressure (IOP) control comprised combined trabeculotomy-with-trabeculectomy or goniotomy. Presenting features and treatment outcomes at one year were compared among babies with and without rubella-IgM antibodies. RESULTS Of twenty-seven eligible infants, 7(25.9%) were rubella-IgM positive, and all had bilateral glaucoma. One eye in a rubella-positive baby was an unsightly blind eye and required a prosthesis. 13 eyes of 7 patients were compared to thirty-four eyes of 20 rubella-negative patients. There was no significant difference in mean age and IOP at presentation. Rubella-positive babies had significantly more opaque corneas (p< 0.001), shorter eyes (p<0.001) and smaller corneal diameters (p=0.007) at presentation. Two patients in the rubella group had bilateral cataracts, 3 had heart disease, and 1 had sensorineural deafness. Salt-and-pepper-retinopathy was noted in both rubella positive babies where fundus evaluation was possible. Despite comparable IOP control (p=0.51), the corneal clarity remained significantly worse in the rubella-positive patients (p=0.02). CONCLUSION Twenty-five percent of newborn glaucoma had underlying intrauterine rubella infection thus making them susceptible for development of congenital rubella syndrome. Neonatal-onset glaucoma is an important component of congenital rubella syndrome, which may present without buphthalmos and persistent corneal clouding despite good IOP control.

Abstract
Background The COVID-19 pandemic and the associated economic recession has increased parental psychosocial stress and mental health challenges. This has adversely impacted child development and wellbeing, particularly for children from priority populations (culturally and linguistically diverse (CALD) and rural/regional communities) who are at an already increased risk of health inequality. The increased mental health and psychosocial needs were compounded by the closure of in-person preventive and health promotion programs resulting in health organisations embracing technology and online services. Watch Me Grow- Electronic (WMG-E) – developmental surveillance platform- exemplifies one such service. WMG-E was developed to monitor child development and guide parents towards more detailed assessments when risk is identified. This Randomised Controlled Trial (RCT) aims to expand WMG-E as a digital navigation tool by also incorporating parents’ mental health and psychosocial needs. Children and families needing additional assessments and supports will be electronically directed to relevant resources in the ‘care-as-usual’ group. In contrast, the intervention group will receive continuity of care, with additional in-person assessment and ‘warm hand over’ by a ‘service navigator’ to ensure their needs are met. Methods Using an RCT we will determine: (1) parental engagement with developmental surveillance; (2) access to services for those with mental health and social care needs; and (3) uptake of service recommendations. Three hundred parents/carers of children aged 6 months to 3 years (recruited from a culturally diverse, or rural/regional site) will be randomly allocated to the ‘care-as-usual’ or ‘intervention’ group. A mixed methods implementation evaluation will be completed, with semi-structured interviews to ascertain the acceptability, feasibility and impact of the WMG-E platform and service navigator. Conclusions Using WMG-E is expected to: normalise and de-stigmatise mental health and psychosocial screening; increase parental engagement and service use; and result in the early identification and management of child developmental needs, parental mental health, and family psychosocial needs. If effective, digital solutions such as WMG-E to engage and empower parents alongside a service navigator for vulnerable families needing additional support, will have significant practice and policy implications in the pandemic/post pandemic period. Trial registration The trial (Protocol No. 1.0, Version 3.1) was registered with ANZCTR (registration number: ACTRN12621000766819) on July 21st, 2021 and reporting of the trial results will be according to recommendations in the CONSORT Statement.

Abstract
BACKGROUND The obstetric quality of recovery scoring tool (ObsQoR-11) was developed and validated in the United Kingdom for use after elective and emergency caesarean delivery. Quality of recovery scoring tools validated in one country may not be valid in other countries with significant cultural, socio-economic and linguistic variations. The aim of the current study was to validate a Hindi version of the ObsQoR-11. METHODS In this prospective observational study, 100 parturients who underwent elective caesarean delivery in a tertiary care obstetric referral university hospital in North India were asked to complete a Hindi version of the ObsQoR-11 scoring tool 24 h after surgery. The performance of the Hindi version of ObsQoR-11 was assessed using measures of validity, reliability, and feasibility. RESULTS The Hindi version of ObsQoR-11 correlated moderately with the global health visual analogue scale (r=0.45, 95% CI 0.27 to 0.59; P <0.0001) and discriminated well between good and poor recovery (mean (SD) score 84.6 (9.4) vs 75.0 (11.2); P <0.0001). The reliability and internal consistency were moderate (Cronbach's alpha=0.66; Spearman-Brown Prophesy Reliability estimate=0.57) with good repeatability (intraclass correlation coefficient 0.85, 95% CI 0.69 to 0.93; P <0.0001) and no floor or ceiling effects. All parturients completed the questionnaire (median (IQR) time of completion of 3 (1.5 - 5.5) min). CONCLUSION The Hindi version of the ObsQoR-11 questionnaire is a promising scoring tool to evaluate quality of recovery after elective caesarean delivery. Further research is needed to evaluate the Hindi tool in other institutions in India, as well as in other languages.

Abstract
Abstract
Aim
This systematic review aims to understand the relationship between version abnormalities of the femur and acetabulum in patients with primary and secondary femoroacetabular impingement (FAI).
Method
A systematic review was conducted according to PRISMA guidelines. A computer-based search was performed using the EMBASE, MEDLINE, PubMed and Cochrane databases for articles relating to version and torsional abnormalities in FAI, Legg-Calve-Perthes disease (LCPD) and slipped capital femoral epiphysis (SCFE). The study was registered in the Open Science Framework. Two authors independently performed title/abstract and full text screening according to predetermined inclusion criteria.
Results
A total of 1206 articles were identified 55 articles, involving 10, 091 hips, met the inclusion criteria. All studies evaluating femoral/acetabular version in FAI reported ‘normal’ mean version values (10o to 25o). However, distribution analysis revealed that an estimated 31.4% and 51.3% of patients with FAI displayed abnormal acetabular and femoral version, respectively. Abnormal femoral version was reported in an estimated 74.5% of hips with LCPD, and abnormal acetabular version in an estimated 20%. Acetabular version was significantly lower in hips with SCFE compared to controls (Z=-3.26, P < 0.01).
Conclusions
Patients presenting with hip pain attributed to FAI are likely to display an abnormality in femoral or acetabular version. This highlights the importance of evaluating these parameters during assessment of these patients, in order to guide clinical decision making.

Abstract
Abstract
Aim
Salvage Robot-Assisted Radical Prostatectomy (sRARP) is a potential treatment option for locally recurrent Prostate Cancer after non-surgical primary treatment. There are minimal data comparing outcomes between propensity-matched salvage and primary Robot-Assisted Radical Prostatectomy (RARP). We compare perioperative, oncological, and functional outcomes of sRARP with primary RARP and between sRARP post-whole and focal gland therapy.
Method
1:1 propensity-matched comparison of 146 sRARP with primary RARP from a cohort of 3,852 consecutive patients from a high-volume tertiary centre.
Results
There were no significant differences in patient characteristics between the salvage and primary RARP groups. Grade III-V Clavien-Dindo complication rates were 1.3% and 0% in the salvage and primary groups, respectively (p = 0.310). Median (IQR) follow-up was 16 (10,30) and 21 (13,33) months in the salvage and primary groups, respectively. BCR rates were 30.8% and 13.7% in the salvage and primary groups, respectively (p < 0.001). Pad-free continence rates were 79.1% and 85.4% at two years in the salvage and primary groups, respectively (p = 0.160). ED rates were 95.2% and 77.4% in the salvage and primary groups, respectively (p < 0.001). Comparing the whole gland and focal gland groups, BCR rates were 33.3% and 29.1%, respectively (p = 0.687), pad-free continence rates were 66% and 89.3%, respectively (p = 0.001), and ED rates were 98.3% and 93%, respectively (p = 0.145).
Conclusions
SRARP has similar perioperative but inferior oncological outcomes to primary RARP. Continence rates are similar to primary RARP, but potency is worse. Perioperative and oncological outcomes of sRARP after focal gland therapy are similar but continence outcomes are superior compared to sRARP after whole gland therapy.

Abstract
Abstract
Background
The aim is to evaluate if different social reality could represent a prognostic factor as associated anomalies affecting survival of neonates with esophageal atresia (EA).
Method
Retrospective analysis of records of neonates with EA with or without Tracheoesophageal Fistula (TEF) from January 2011 to September 2018 at Policlinico San Matteo Pavia, Italy(SMAT) and the All India Institute of Medical Sciences New Delhi, India (AIIMS).Survival was correlated with the presence of anomalies, different types and the number of organ systems involved.Age at presentation and birth weight were considered to find an association with mortality.
Results
Out of 180 patients,162 were from AIIMS and 18 from SMAT.The overall mortality was 28.85%, which occurred at AIIMS, being 0% at SMAT.83.33% at SMAT and 72.84% at AIIMS had associated anomalies.The mortality was 25% for neonates without an anomaly, being 26.15% for those with one (p > 0.05).No statistically significant correlation between outcome and associated anomalies was found.Instead, survival declines gradually as the age at presentation increases.
Conclusions
The presence of associated anomalies paradoxically does not affect the outcome because incidence of delayed presentation has a stronger effect than the presence of associated anomalies. Sensibilization is necessary to improve survival in EA neonates in developing countries, such as India.

Abstract
Abstract
Introduction
OPSCC often (80%) presents with ipsilateral neck metastasis. Presentation may be as carcinoma of unknown primary (CUP). Sampling via ultrasound guided Fine Needle Aspiration Cytology (FNAC) and/or Core Biopsy (CB) from nodal metastases is required for diagnosis, comparison with primary tumour and to assess human papilloma virus (HPV) status. HPV positive biopsy from CUP may indicate oropharynx primary. HPV positive OPSCC has better prognosis. HPV association is ascertained by p16 immunocytochemistry (p16- IHC) and HPV DNA in situ hybridization (HPV-ISH). In a cohort of OPSCC patients from a single referral centre 68% had metastatic disease. Core biopsy was optimal for HPV testing.
Method
Retrospective review of records from Transoral Robotic Surgery (TORS) patients treated for OPSCC between December 2017-2019 was conducted. Cohort included patients undergoing TORS for diagnostic purposes and with curative intent.
Results
Data was available from 23 patients who had TORS for OPSCC. 47.8% (n = 11) presented with lymphadenopathy. 82.6% (n = 19) underwent FNAC. 68.4% (n = 13) were diagnosed with metastatic OPSCC and 56.5% (n = 13) underwent neck dissections. 52.2% (n = 12) had confirmed HPV positive metastases, 75% (n = 9) had 1 node positive, 25% (n = 3) had >1 node positive. FNAC yielded enough tissue for p16 IHC and HPV-ISH in 10.5% (n = 2). CB yielded sufficient tissue for analysis in all cases 39.1% (n = 9).
Conclusions
The study confirms high incidence of neck metastases in HPV associated OPSCC patients. Needle core biopsy appears superior to FNAC for tissue sampling to assess HPV status in tumours metastatic to neck.

Abstract
Abstract
Aim
The use of transoral robotic surgery (TORS), transoral laser microsurgery (TLM) and more recently reported transoral endoscopic electrocautery (TOEC) in the identification of the primary cancer in CUP patients has gained popularity. This systematic review aims to assess the effectiveness of TORS, TLM and TOEC.
Method
A systematic review and meta-analysis using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) reporting methodology was carried out to assess the effectiveness of the three trans-oral surgical techniques. EMBASE, MEDLINE and CINAHL databases were searched from inception to September 2020. Primary outcome measure was detection rates of primary cancer of the different techniques. Secondary outcome measures were complications and length of hospital stay.
Results
289 studies were identified of which 30 met the inclusion criteria (28 case series and 2 case reports). The overall combined primary identification rate was 72.3% (567 /777 patients). The primary identification rates were 49.7% and 34.2% in lingual (n = 273) and palatine tonsillectomy (n = 118) respectively. The primary cancer identification rates by surgical techniques are: TORS was 60% (CI 0.49, 0.70), TLM was 80% (CI 0.58, 1.01), TOEC was 41% (CI 0.05, 0.76). The commonest complication was haemorrhage (5.3%).
Conclusions
This is the largest systematic review in the subject and incorporates the more recently published surgical technique of TOEC. Lingual tonsillectomy is an effective procedure in CUP work up. Further larger, multi-centre, prospective studies of PET CT negative CUP patients is needed to draw conclusive results

Abstract
Bilateral sagittal split osteotomy (BSSO) is the most common orthognathic surgical procedure for the correction of facial deformities. Like any other surgical procedure, it is also associated with a risk of complications. One of these is described in the literature as notching at the lower inferior border of the mandible. Such discontinuity in the contour of the lower border is often a concern for patients. To overcome this complication, we recommend a modified vertical osteotomy cut while performing BSSO.

Abstract
Purpose: The purpose of this study is to evaluate the anatomical and functional outcomes of 25-gauge (G) pars plana vitrectomy (PPV) in patients with cytomegalovirus retinitis (CMVR)-related rhegmatogenous retinal detachment (RRD). Methods: Single-center retrospective consecutive case series of patients who underwent 25-G PPV for CMVR-related RRD repair with a minimum follow-up of 3 months. Complete anatomic success was defined as the complete attachment of retina including the periphery. Best-corrected visual acuity (BCVA) of ≥20/400 was defined as functional success. Results: Sixteen eyes of 15 patients were included in the study. Eleven patients were human immunodeficiency virus positive, three patients had hematological malignancies, and one patient suffered from dyskeratosis congenita. The mean follow-up was 20.5 ± 17.4 months (range 3–60 months). Complete anatomical success was seen in 15 eyes (93.75%). One eye had a residual inferior detachment with attached macula. Silicone oil was used as tamponade in 15 eyes and C3F8 gas in one eye. The mean change in BCVA was statistically significant, preoperative LogMAR BCVA was 2.05 ± 0.94 while the final follow-up postoperative LogMAR BCVA was 1.03 ± 0.61 (P < 0.001). Thirteen eyes (81.25%) had final BCVA ≥20/400. Conclusion: Microincision vitrectomy surgery can achieve excellent retinal reattachment rates in post-CMVR RRDs without significant intraoperative and postoperative complications. The visual outcome varies depending on the status of the optic disc and macula. Majority of the patients maintained functional vision.

Abstract
Purpose The aim of this study was to describe the effectiveness of goniotomy for childhood glaucoma in Indian eyes. Methods Consecutive patients with pediatric glaucoma who underwent goniotomy between July 2017 and June 2020, in a single center in Northwest India were prospectively analyzed. Goniotomy was done as a primary procedure or a re-do surgery of the untreated angle in failed filtering surgery. Success was defined as intraocular pressure (IOP) ≦18 mm Hg with or without 2 topical medications. Results A total of 172 eyes of 126 children underwent goniotomy during this period (37.9% of all pediatric glaucoma surgeries). Goniotomy comprised 132 of 211 (62.5%) primary pediatric glaucoma surgeries and 40 of 243 (16.5%) re-do surgeries. 145, 112, and 54 eyes had a six months, 1-year and 2-year follow-up, respectively. At 1 year, success rates in Primary Congenital Glaucoma (PCG) were 79.7% for primary surgery and 68.4% for re-do surgery. For non-PCG eyes, the success rate was 62% at 1 year. Among PCG subgroups, infantile and newborn glaucoma had 87.5% and 57.1% success rates, respectively. On logistic regression analysis, lower baseline IOP and lesser axial length at presentation were significantly predictive of successful outcomes (P = 0.03 and P = 0.02, respectively). At 1 year, in the primary surgery group, 50% had good vision (better than logMAR 0.5), 28.9% had moderate (better than LOGMAR 1.0) and 20% had severe visual impairment. There were no significant intraoperative or post-operative complications. Conclusion Goniotomy appears to be an effective surgery for childhood glaucoma in Indian eyes. Being minimally invasive, it obviates the need for conjunctival and scleral dissection and antifibrotic agents.
