RESUMEN
PURPOSE: This study aimed to evaluate and compare surgical outcomes among neovascular glaucoma patients undergoing trabeculectomy (Trab), glaucoma drainage device (GDD) implantation, or trans-scleral cyclophotocoagulation (TSCPC). METHODS: This study analyzed the records of 176 neovascular glaucoma cases treated surgically between January 2017 and December 2021 at four Indian centers. Procedures included trabeculectomy with MMC in 80 eyes, GDD implantation in 25 eyes, and TSCPC in 71 eyes. Outcome measures comprised intraocular pressure (IOP) reduction, antiglaucoma medication (AGM) usage, complications, and best-corrected visual acuity (BCVA). RESULTS: Following surgery, all groups exhibited a significant reduction in IOP. One year postoperatively, complete success rates were 42.9% for the implant group, 54.3% for the Trab group, and 33.3% for the TSCPC group, with corresponding qualified success rates of 57.1%, 36.7%, and 58.9%, respectively. Improvement in postoperative vision was noted, with an increase of 0.24 LogMAR in the Trab group, 0.11 in the GDD group, and a decrease of 0.35 in the TSCPC group. Complications occurred in 27% of Trab and 14% of TSCPC cases, while the GDD group experienced a hypertensive phase in 40% of eyes. CONCLUSION: In managing neovascular glaucoma, trabeculectomy, GDD, and TSCPC provide comparable IOP control, with GDD showing a higher medication dependency. Trabeculectomy yields superior vision outcomes but carries a higher risk of postoperative complications, emphasizing the importance of individualized treatment selection and vigilant postoperative care.
RESUMEN
PURPOSE: The purpose of the study was to evaluate the intermediate-term outcomes of Aurolab aqueous drainage implant (AADI) in terms of intraocular pressure (IOP) lowering from baseline levels, the number antiglaucoma medications (AGMs) in the postoperative phase, and the rate of complications. METHODS: It was a retrospective interventional case series. All patients who underwent AADI surgeries with sulcus fixation from March 2018 to September 2018 at a tertiary eye care hospital in North India with a minimum follow-up of 1 year were recruited for the study. A standard AADI technique was employed. The primary outcome measures were the postoperative IOP, the requirement of AGMs, and early and late postoperative complications. RESULTS: A total of 20 patients were recruited in the study. The mean follow-up period was 25.25 ± 3.76 months. The mean IOP reduced from 33.20 ± 7.95 mmHg to 19.45 ± 9.19 mmHg at day 1, 13.62 ± 3.92 mmHg at 6 months, 12.78 ± 3.36 mmHg at 1 year, and 13.0 ± 2.53 mmHg at 2 years postoperatively (P < 0.001). The mean number of AGMs also reduced from 3.7 ± 0.97 to 0.35 ± 0.81 at 6 months, 0.42 ± 0.83 at 1 year, and 0.26 ± 0.73 at 2 years postoperatively (P < 0.001). Early postoperative complications, such as hypotony and hyphema, were seen in 5 (25%) patients, although none of them was sight-threatening. Late postoperative complications, such as hypertensive phase and persistent fibrinous membrane, were also seen in five eyes. CONCLUSION: The study assessed the clinical outcomes, safety profile, and long-term AGM requirement with AADI and found it to be a good viable surgical option in refractory glaucoma.

Purpose: To ascertain the prevalence and clinical features of the various types of childhood glaucoma at a tertiary eye care hospital in Northern India. Materials and methods: Retrospective chart review of all children less than 16 years of age with childhood glaucoma who presented from 1st April 2014 to 31st March 2019, who was diagnosed to have any subtype of childhood glaucoma as per Childhood Glaucoma Research Network (CGRN) classification and advised appropriate management. Results: Out of 405 children with childhood glaucoma, 36% had primary glaucoma, whereas the rest had secondary glaucoma. Primary congenital glaucoma (PCG) was the most common form of primary glaucoma. Glaucoma associated with acquired conditions was the most common cause of secondary glaucoma. Primary glaucoma was mostly bilateral in contrast to secondary glaucoma. The most common age of presentation with primary glaucoma was <1 year of age, and in children with secondary glaucoma was 11-16 years. On presentation, 80% of eyes had intraocular pressure (IOP) of >20 mm Hg and 70% had cupping of >0.7. Eyes with PCG were primarily managed surgically. Conclusion: In our cohort, PCG was the most common primary childhood glaucoma. Traumatic glaucoma was the most common secondary glaucoma. Since childhood glaucoma is an important cause of visual morbidity in children, its timely diagnosis and prompt management are essential to prevent irreversible visual loss. Clinical significance: Understanding the disease pattern, their presenting features, and the proportion of different types of childhood glaucoma can help in planning appropriate eye care services, create awareness and better allocate resources to plan appropriate management strategies. Screening programs and counseling of parents should also be strengthened. How to cite this article: Dubey S, Jain K, Pegu J, et al.

RESUMEN
Purpose: Consensual eye intra-ocular pressure (IOP) increase has been reported following ipsilateral glaucoma surgery. The study evaluated the need for increase in anti-glaucoma medications (AGM) ± glaucoma surgery to control the IOP in consensual eye following unilateral glaucoma surgery. Methods: Data of 187 consecutive patients who underwent either trabeculectomy or AGV implant were collected. Index (IE) and fellow eye (FE) IOP (baseline, follow-up day 1, week 1, months 1 and 3), acetazolamide and AGM use, FE surgery, glaucoma status, and relevant ophthalmological data were collected. Results: A significant increase from a baseline IOP of 14.4 mmHg was noted at week 1 (15.8 mmHg, p-0.005) and month 1 (15.62 mmHg, p-0.007) in FE (n-187). Among the 61 patients (33%, n-187) who needed additional intervention to reduce FE IOP, 27 (14.4%) underwent FE trabeculectomy. In the IE trabeculectomy group (n-164), significant increase in FE IOP was noted in week 1 (15.87 mmHg, p-0.014) and month 1 (15.61 mmHg, p-0.02), and in the IE AGV group (n-23) at day 1 (15.91 mmHg, p-0.06). Pre-operative acetazolamide resulted in significant increase in FE IOP at week 1 and month 1. Maximum increase in FE IOP of nearly 3.5 mm Hg was noted when IE IOP was persistently <5 mmHg at one month following surgery. Mean FE IOP remained elevated at all visits. Conclusion: An increase in fellow eye IOP needing any additional intervention in a third and surgical intervention in nearly a sixth meant that FE IOP be strictly monitored and addressed following unilateral glaucoma surgery.

Purpose: To determine the incidence of vitreous loss and visual outcome after a vitreous loss during cataract surgery performed by surgeons with various levels of experience in adults >40 years of age at a tertiary eye care center in North India. Methods: The study was conducted at a tertiary eye care center in North India. This was an observational, retrospective, cross-sectional study of patients who underwent cataract surgery from August 1, 2011 to July 31, 2014. All adult cataract cases who were operated on from August 1, 2011 to July 31, 2014 and who experienced vitreous loss during their surgery were included in the study. The visual outcomes of these patients who experienced vitreous loss during cataract surgery in uncomplicated cataract and were managed using standard automated vitrectomy techniques were assessed for different cataract surgical techniques (extracapsular, small-incision, and phacoemulsification) as well as at different levels of skill of the operative surgeon (consultant, short term fellow, and long-term fellow). Details of the postoperative period and best-corrected visual acuity (BCVA) were collected from patient records by the principal investigator on day 1, 1 week, 4 weeks, 6 weeks, and 3 months post cataract surgery. Results: Vitreous loss occurred in 374 out of 18,430 patients who underwent cataract surgery from August 1, 2011 to July 31, 2014. The overall incidence of vitreous loss in our study was found to be 2.03% with consultants having a rate of 1.66%, short-term fellows at 5.19%, and long-term fellows at 2.02%. Two hundred eighty-eight patients of the 374 cases followed up for 3 months at the hospital and 75.69% of these patients had a final visual acuity of ≥6/18. Conclusion: In an institute with a structured training program for residents/trainees, the vitreous loss rate is low during cataract surgery. Early intervention and proper management with the standard microsurgical technique by experienced hands can improve the final visual outcome in eyes with vitreous loss. Cystoid macular edema and corneal edema were the most common causes of poor postoperative vision.

Purpose: To determine the association of primary angle-closure disease (PACD) in patients with retinal vein occlusion (RVO) at a tertiary eye care center in North India. Methods: It is a cross-sectional, observational study. Sixty consecutive patients with retinal vein occlusion within a period of one year from a single tertiary eye care center were enrolled. Detailed history, slit-lamp examination of the anterior segment, intraocular pressure measurement by applanation tonometry, gonioscopy and fundus examination were done. Anterior chamber depth and axial length were also measured. Results: Among the 60 patients, 29 were males (48.3%) and 31 females (51.6%). Twenty-seven (45%) of them had central retinal vein occlusion (CRVO) and 33 (55%) had branch retinal vein occlusion (BRVO). Forty percent of patients with RVO had PACD. Relative risk of PACD was 1.71 times in patients with CRVO as compared to BRVO. Risk of glaucoma was 49% more in CRVO than BRVO. Probability of PACD was more in patients of RVO who had diabetes and CAD as comorbidity. Conclusion: The association between PACD and RVO is less known. PACD can be one of the risk factors for the development of RVO. A comprehensive examination and detailed angle evaluation of both of the eyes should be done in all cases of RVO, in addition to investigating for systemic risk factors. However, larger population-based studies would be required to prove it as an independent risk factor.

PURPOSE: To study the correlation between choroidal thickness (CT) and IOP control in primary angle-closure glaucoma (PACG). METHODS: In total, 61 patients (102 eyes) with PACG underwent subfoveal CT (SFCT) scanning using enhanced depth imaging-optical coherence tomography. The subjects with PACG were further grouped as controlled IOP (≤21 mm Hg on maximal medical therapy) and uncontrolled IOP (>21 mm Hg on maximal medical therapy). The average CT of the PACG eyes was calculated and compared between both groups. A correlation analysis was done between CT and intereye difference in CT with the disease parameters. RESULTS: The mean CT was 274.38 ± 42.10 µm in 102 PACG eyes. SFCT was significantly increased in the uncontrolled IOP group as compared with the controlled IOP group. The mean SFCT was 245.57 ± 62.10 µm in the controlled group and 294.46 ± 51.05 µm in the uncontrolled group (P < 0.01). Factors associated with a thicker choroid were younger age, high IOP, and higher optic nerve head cupping (P < 0.001). Neither the visual field-mean deviation (VF-MD) nor pattern standard deviation (PSD) was found to be associated with overall CT. The intereye asymmetry between CT was significantly associated with poor VF-MD and PSD. CONCLUSION: PACG eyes with thicker choroid may be a risk factor for poor IOP control on medical anti-glaucoma therapy. Thicker choroid as compared to the fellow eye is a poor prognostic sign and these eyes should be monitored closely.

PRECIS: The vessel density (VD) and perfusion density (PD) generated by optical microangiography (OMAG) is significantly affected by the signal strength (SS). Sex, hypertension, diabetes, and axial length did not have any statistically significant effect on these measurements. PURPOSE: The aim was to assess the effect of subject-related factors (age, sex, systemic hypertension, diabetes, and axial length) and machine-related factor (SS) on VD and PD generated by OMAG in peripapillary and macular regions. METHODS: In an observational, cross-sectional study of 200 eyes of 100 healthy individuals (age: 18 to 80 y), mean and sectoral VD and PD were calculated on disc and macular scans. Effect of subject-related and machine-related factors on VD and PD parameters were evaluated using multivariate mixed effect models. RESULTS: Mean±SD peripapillary and macular VD of the study population was 18.56±1.11 and 20.59±1.85 mm-1, respectively. Mean peripapillary and macular PD was 46.43±3.22% and 37.61±3.26%, respectively. Sex, hypertension, diabetes, and axial length did not have any statistically significant effect on the OMAG measurements (P>0.05 for all associations). However, the SS had significant effect on the OMAG measurements. Mean peripapillary and macular VD on scans with SS of 10 was 1.4 and 3.79 mm-1 greater, respectively, than that on scans with SS of 7. Mean peripapillary and macular PD on scans with SS of 10 was 4.43% and 7.85% greater, respectively, than that on scans with SS of 7. CONCLUSION: Significant association exists between SS of the scan and the optical coherence tomography angiography measurements generated by OMAG even when the scans have acceptable SS as recommended by the manufacturer (≥7). This needs to be considered while interpreting optical coherence tomography angiography measurements.

Purpose: The purpose of this study is to assess the effect of dexmedetomidine on intraocular pressure (IOP) as an additive in peribulbar injections in glaucoma surgeries. Methods: A prospective, randomized, double-blind, parallel assignment interventional study was conducted for patients undergoing glaucoma surgeries at a tertiary eye care hospital in North India. Patients were randomized to two groups, Dexmed group and Placebo group. In the Dexmed group, dexmedetomidine (0.4 µg/kg body weight) was given as an additive along with peribulbar block. The primary outcome was change in IOP pre- and postperibulbar injections (IOP before the block, and after 5 and 15 min of the block). Secondary outcome measures were onset of block, adverse effects (bradycardia, hypotension, respiratory depression, and level 4 sedation), and surgeon satisfaction. Results: A total of 104 patients were randomized, 52 each in the Dexmed group and Placebo group. The percentage decrease in IOP was significantly more in the Dexmed group than in the Placebo group both at 5 and 15 min' post block (P < 0.05). At 5 min, the mean percent decrease in IOP in Dexmed group was -10.48, whereas it was 2.85 in the Placebo group. At 15 min, the mean percent decrease in IOP was -22.59 and -9.42 in the Dexmed and Placebo group, respectively. There was no significant difference between the two groups in the onset of block and adverse effects. Surgeon satisfaction was significantly greater in the Dexmed group than the Placebo group (P < 0.05). Conclusion: Dexmedetomidine lowers IOP significantly in patients undergoing glaucoma surgeries with safe hemodynamic changes and sedative effect.

An iris cyst is a nonkeratinized squamous epithelial-lined space involving a layer of iris. The presentation of iris cyst can be variable-innocuous or presenting with secondary complications. The identification of whether the cyst is primary or secondary is important. The prognosis of primary iris cysts is good, as the majority does not require treatment and that of secondary iris cysts is much more capricious depending on their presentation. Their optimal management often poses a challenge for ophthalmologists. Here, we will present two cases of iris cysts with diverse presentation along with a review of the literature of this rare clinical entity.
RESUMEN
PURPOSE: The purpose of the study was to report a small case series of patients with iridoschisis seen at our hospital over a period of 5 years. METHODS: Retrospective review of all those files over the past 5 years whereby the diagnosis of iridoschisis/iris atrophy/iris fibrils in anterior chamber (AC) was made. RESULTS: In our case series, the average age at presentation was 49 years (range: 23-85 years). The pathology was bilateral in 57% of patients in our series. Our most common presentations were angle closure glaucoma and cataract. Younger individuals can also manifest iridoschisis. CONCLUSION: The iridoschisis can be an incidental finding, and gonioscopy should be performed in all the cases, as occludable or synechiael angle closure may be present in these cases.

Ocular amylodosis, although a rare entity, is known to affect the conjunctiva, extraocular muscles, orbit, lacrimal gland, and skin around the eyes. Intraocular deposition of amyloid mainly confines to the vitreous and cornea. In this report, we describe two cases of intraocular amyloidosis presenting as multiple iris and anterior chamber cysts. Histopathological examination with special stain like Congo Red and Transmission Electron Microscopy confirmed the diagnosis of amyloidosis. Systemic investigations ruled out systemic association confirming the diagnosis of primary ocular amyloidosis.
