- Abstract
Glaucoma drainage devices are invaluable in the management of secondary/ refractory glaucomas. This study aimed to compare the efficacy and safety of Aurolab Aqueous Drainage Implant (AADI) and the Ahmed Glaucoma Valve (AGV) in filtration-surgery-naïve secondary glaucoma eyes. For this purpose, a retrospective, comparative review was conducted on patients with secondary glaucoma (open and closed) who underwent primary tube procedures, either AADI or AGV. The primary outcome measure was intraocular pressure (IOP), and secondary measures included best-corrected visual acuity (BCVA), number of antiglaucoma medications (AGMs), and complications. This study included 59 eyes in the AADI group with a mean follow-up of 20.3 ± 12.9 months and 61 eyes in the AGV group with a mean follow-up of 19.8 ± 11.8 months. Preoperative IOP, AGM use, and BCVA did not significantly differ between the groups. However, at the last visit, both IOP and AGM use were significantly lower in the AADI group (12.9 ± 3.7 mmHg and 0.6 ± 0.9 vs. 15.7 ± 2.7 and 1.8 ± 1.0 respectively, all p < .001). Moreover, the AADI group exhibited a significantly higher rate of complete success (57.6%) compared to the AGV group (14.7%, p < .001); corresponding qualified success was 91.5% and 80.3%. Serious complication rates were comparable between the two groups. In conclusion, toth AADI and AGV procedures effectively reduced IOP and the need for AGMs. However, the reductions were significantly greater in the AADI group, which also showed a higher rate of complete success. Considering its affordability, AADI could have a substantial positive impact, particularly in resource-constrained settings., (Copyright © 2024 Indian Journal of Ophthalmology.)

- Abstract
Purpose: This present prospective, cross-sectional study aims to comprehensively evaluate the ocular surface in asymptomatic patients with diffuse blebs after trabeculectomy versus chronic anti-glaucoma medication use and compare it with the age-matched normal population., Methods: Objective clinical evaluation was done by tear film break-up time (TBUT) and Schirmer's test (ST) in the three groups-trabeculectomy >6 months with a diffuse bleb (Wurzburg bleb classification score ≧10), chronic anti-glaucoma medication (AGM >6 months) group, and normal population. In all groups, tear film osmolarity was checked with the TearLab
® device (TearLab Corp., CA, USA), and subjective evaluation was performed by administering Ocular Surface Disease Index (OSDI) questionnaire. Patients already on chronic lubricants or any other drug for the treatment of dry eyes (viz. steroids, cyclosporin) or having symptoms suggestive of an abnormal ocular surface, who had undergone refractive or intraocular surgery, and contact lens users were excluded., Results: In total, 104 subjects/eyes were recruited over 6 weeks. Thirty-six eyes recruited in the trab group were compared with 33 eyes studied in the AGM group, and both these groups were compared to 35 normal eyes. When compared to normals, TBUT and ST were significantly lower (P = 0.003 and 0.014) and osmolarity and OSDI were statistically significantly higher (P = 0.007 and 0.003) in the AGM group, whereas only TBUT was statistically significantly different (P = 0.009) when the trab group was compared to normals. Also, when the trab group was compared to the AGM group, ST was found to be higher (P = 0.003) and osmolarity was lower (P = 0.034)., Conclusion: To conclude, ocular surface is affected even in asymptomatic patients on AGM but near normalcy is possible following trabeculectomy when blebs are diffuse., Competing Interests: None- Published

- Abstract
Purpose: To report the initial clinical outcomes of combining glaucoma surgery with flanged intrascleral intraocular lens (F-SFIOL) fixation as a single stage procedure., Methods: Retrospective, non-comparative case-series of eyes which underwent combined surgery for glaucoma with F-SFIOL and had at least 6-months of follow-up. A fellowship-trained senior glaucoma surgeon managed all the cases., Results: Twelve-eyes of 10 glaucoma patients (8 males, 2 females) underwent F-SFIOL; only 8 of these eyes were combined with a glaucoma procedure. Mean age of patients was 55.1 ± 16.1 years (95%CI [44.4,73.2], median 61 years) and were followed-up for a mean of 21.0 ± 9.5 months, 95% CI [13.1,28.9], median 18 months. F-SFIOL was combined with trabeculectomy ± Mitomycin C in 4 eyes, Ahmed Glaucoma Valve in 3 eyes and needling of a pre-existing bleb in 1. Each eye had controlled intraocular pressure (IOP) at last follow-up (pre-procedure 29.1 ± 13.4 mmHg, 95% CI [17.9, 40.3], median 27 mmHg to 14.5 ± 3.2 mmHg, 95% CI [11.8, 17.1], median 13 mmHg, p = 0.006) and decreased need for number of anti-glaucoma medication (AGM) (pre-procedure 3.7 ± 1.1, 95% CI [2.8,4.6], median 4 to 0.7 ± 0.7, 95% CI [0.1,1.3] median 1, p < 0.001). In all the eyes, best corrected visual acuity (BCVA) was either stable or improved; only 1 eye had astigmatism worse than that pre-existing. In 1 eye IOL was explanted, with an additional procedure to control IOP. No serious long-term complications occurred in any subject., Conclusion: The initial experience of single-stage F-SFIOL along with glaucoma surgery, both being performed by the same anterior-segment surgeon, is promising, thereby avoiding the cost, specialised skill, and potential complications of a posterior approach. Glaucoma surgery combined with and adapted to suture-less, flap-less, glue-less intra-scleral IOL fixation is hitherto unreported.

- Abstract
Purpose: To report long-term outcomes in eyes that developed late-onset bleb leak post trabeculectomy, with or without hypotony and/or maculopathy, due to a scleral melt/fistula and who required a scleral patch graft and conjunctival advancement for repair., Methods: Retrospective, non-comparative, interventional case series over a decade (2010-2019), presenting with late bleb leak post-filtration-surgery. All cases required a scleral patch graft and conjunctival advancement for management via a standard technique, performed by an experienced glaucoma surgeon., Results: A total of 18 eyes were included. Mean age was 51.5 ± 10.2 years (95% CI [46.4-56.7]) and were followed up after repair for 52.4 ± 26.9 months, 95%CI [39.1-65.8]. 66.7% eyes (n = 12) had IOP ≦6 mmHg and also had hypotony maculopathy. None of the eyes presented with blebitis. 44.5% (n = 8) eyes underwent phacoemulsification as significant cataract was present. LogMAR best-corrected visual acuity (BCVA) was 0.8 ± 0.7 (95% CI [0.4-1.1]) prior to intervention and improved to 0.4 ± 0.6 (95% CI[0.1-0.6], P = 0.004). 22.3% (n = 4) eyes had persistent choroidal folds but BCVA was improved. Mean pre-intervention intraocular pressure (IOP) was 6.3 ± 3.8 mmHg (95% CI 4.4-8.2]) which increased to 12.1 ± 2.9 mmHg (95%CI[10.6-13.5], (P < 0.001). 27.8% (n = 5) eyes needed laser suture lysis post repair to control IOP; two needed further surgical intervention. Number of anti-glaucoma medications at last follow-up was 0.4 ± 0.9 (95% CI [-0.1-0.8], P = 0.09). No serious complications were encountered., Conclusion: Scleral patch graft and conjunctival advancement is a useful technique for repair of a scleral fistula post-filtering surgery, and this is recommended not only for the restoration of anatomy for prevention of infection and control of IOP, but also for visual rehabilitation., Competing Interests: None

- Abstract
Purpose: There is a considerable lack of awareness of slit-lamp measurement of anterior chamber depth (ACD) by the Redmond Smith method (SACD) in present day-to-day clinical practice, which may provide rapid assessment in pseudoexfoliation (PXF) when assessing for angle closure and planning for cataract surgery. This assumes importance not only in outreach clinics but also in the ongoing pandemic caused by the highly contagious novel coronavirus, where social distancing is advocated to contain the spread. We aimed to compare the axial ACD in PXF and normal patients by SACD, and its agreement with the anterior segment optical coherence tomography (ASOCT) and LenstarLS-900., Methods: A prospective comparative observational study was done at a tertiary eye care hospital. A PXF group and a normal group of controls were recruited. All eyes were phakic with normal cornea. Any eye with previous intraocular/refractive surgery and cause of other secondary or uncontrolled glaucoma was excluded. SACD was measured clinically via slit-lamp method and also via ASOCT and Lenstar; agreement between the methodologies was plotted., Results: Fifty patients were recruited in each group. Mean age was 66.82 ± 4.88 years in PXF patients and 65 ± 5.46 years in controls (P = 0.2). ACD was found to be greater in controls compared with the PXF patients; this difference was statistically significant (P < 0.001) across all methodologies. A good agreement with narrow 95% limits of agreement was found between these methodologies., Conclusion: Redmond Smith slit-lamp methodology of estimating the axial ACD is recommended as a rapid, quantifiable, noncontact screening technique during routine examination, especially in primary outreach centers, and is also advantageous during the ongoing pandemic by reducing expendable investigations., Competing Interests: None

- Abstract
Purpose: To demonstrate any transient short-term effect of a particular type of breathing exercise (alternate nostril breathing of Nadi Shuddhi type of pranayama exercise) on the intraocular pressure (IOP) in glaucomatous as well as healthy eyes., Methods: A prospective, nonrandomized, observational, cross-sectional study was conducted in a tertiary eyecare hospital setup recruiting 3 groups of subjects-glaucoma group and a normal group that underwent the breathing exercise as well as a normal group that did not. IOP was recorded at baseline, then at 4 minutes after 10 cycles of the breathing exercise and also after 10 minutes of rest-corresponding to IOPb, IOPc, and IOPr of all the study groups. Only those subjects were recruited who were above 18 and under 80 years and were naive to breathing exercise., Results: A total of 56 normal eyes (28 subjects, Normalb) and 33 glaucomatous eyes (19 subjects) were recruited for the breathing exercise and were compared with the IOP as obtained for 26 eyes of 26 subjects that did not undergo the breathing exercise (Normalnb). IOPb did not differ between both normal groups (13.7±1.4 mm Hg in Normalb vs. 13.9±1.6 mm Hg in Normalnb, P=0.183) but was significantly different between groups (16.7±3.1 mm Hg in the glaucoma group and 13.7±1.4 in Normalb, P<0.001 and Normalnb 13.9±1.6 mm Hg, P<0.001) but analysis of variance was not significant within groups comparing IOPb, IOPc, and IOPr of all the study groups., Conclusion: There is no short-term transient effect of alternate nostril breathing exercise on IOP; a longitudinal study is recommended., Competing Interests: Disclosure: V.P.-R.: Santen, Novartis, Allergan.

- Abstract
Purpose: To investigate the efficacy and safety of endocycloplasty (ECPL) versus trabeculectomy when it is combined with phacotrabeculectomy in medically controlled or uncontrolled primary angle-closure (PAC) or primary angle-closure glaucoma (PACG) after laser peripheral iridotomy (LPI)., Design: Prospective, interventional, randomized control trial., Participants: Subjects with PAC/PACG aged 30 years or more after LPI with visually significant cataract., Methods: Subjects underwent computer-generated randomized sequence of either procedure, phaco-ECPL or phacotrabeculectomy, for standard indications of combined glaucoma and cataract surgery., Main Outcome Measures: Primary outcome measure was intraocular pressure (IOP). Secondary outcome measures were best-corrected visual acuity (BCVA), number of antiglaucoma medications (AGMs), complications, and failure., Results: A total of 45 eyes of 39 subjects were included. A total of 25 eyes underwent phaco-ECPL, and 20 eyes underwent phacotrabeculectomy. Five eyes in the phaco-ECPL group were excluded; 2 were excluded because laser was not delivered per protocol, and the rest had less than 3 months of follow-up. Mean follow-up was 16.25±8.1 months in the phaco-ECPL group and 18.9±9.5 months in the phacotrabeculectomy group. Mean preoperative and postoperative IOP, AGM, and BCVA did not differ between the groups. However, the rate of complications (P = 0.011) and interventions (P = 0.047) was greater in the phacotrabeculectomy group., Conclusions: Both procedures are efficacious in lowering IOP in PACG, but the rate of complication and interventions for these were more in the phacotrabeculectomy group. Longer follow-up is indicated to probe the feasibility of phaco-ECPL, a minimally invasive procedure, as first-step management in PAC disease, for which combined cataract and glaucoma surgery is indicated., (Copyright © 2020 American Academy of Ophthalmology.

- Abstract
Cataract surgery with intraocular lens (IOL) implantation is increasingly preferred over laser peripheral iridotomy as the first-line management of primary angle-closure glaucoma after endorsement by the recently reported EAGLE (Effectiveness of Early Lens Extraction for the Treatment of Primary Angle-Closure Glaucoma) study. However, we present 2 eyes of a 63-year old woman, both of which remained shallow after cataract surgery, with 1 eye developing high and uncontrolled intraocular pressure. Both eyes needed further intervention; the latter eye received surgical treatment as well., (Copyright © 2019 ASCRS and ESCRS. Published by Elsevier Inc. All rights reserved.)

- Abstract
Phacotrabeculectomy is the preferred surgical management of coexisting visually significant cataract and moderate to advanced glaucoma. We report the surgical technique of a new modified fornix-based separate-site phacotrabeculectomy, with mitomycin C (MMC) application, in both primary open angle and angle closure glaucoma. In this new separate-site technique, both phaco and filtration are accommodated superiorly, side by side, hence called twin-site. This was achieved in an efficacious and safe manner with sparing of limbal stem cells without compromising safety. It is not only MMC-compatible but also has a low incidence of wound leak. The technique has no adverse consequence on the survival of the bleb, and we achieved complete success in 79.2% and total success in 93.1% in 130 eyes of 117 patients, in the intermediate term. Furthermore, the time taken for this separate-site surgical technique is comparable to published one-site procedures., Competing Interests: There are no conflicts of interest.

- Abstract
Purpose : The aim of this study is to investigate the ability of ostial irido-zonulo-hyaloido-vitrectomy (ostial IZHV) with primary posterior capsulectomy (PPC) in preventing aqueous misdirection (AM) in combined cataract and filtration surgery in a high-risk group of angle closure disease. Materials and Methods : Comparative case series-data collection of consecutive adult subjects (>18 years) with angle closure, undergoing phaco-trabeculectomy, when per-operatively anterior chamber depth (ACD) remained shallow, putting them at high risk for development of AM post-operatively. Study subjects were compared to controls, who also underwent combined surgery in angle closure, but did not have shallow AC per-operatively, in the study period of January 2012 to December 2016. Ostial-IZHV was done through sclerostomy and iridectomy created routinely as part of the filtration procedure. Main outcome measure- post-operative deep ACD and comparison of biometric (optical) parameters between study subjects and controls. Results : Twelve eyes of 11 primary angle closure glaucoma subjects who underwent ostial-IZHV intra-operatively (study subjects) in the study period were included. None of the subjects developed post-operative AM. The median IOP pre-procedure decreased significantly at average follow-up of 18.25 months (SD 14.1) post-procedure ( p = .003). There was significant decrease in use of anti-glaucoma medications too ( p < .001) post-procedure. When compared to controls, study patients were younger ( p = .006); these eyes demonstrated greater quadrantic synaechial angle closure on gonioscopy ( p < .001), higher pre-operative intraocular pressure ( p = .001) and were also found to be smaller ( p = .011), shallower ( p < .001) with significantly more lens rise ( p = .013). Although lens thickness did not differ ( p = .689), it appeared to be relatively anteriorly placed ( p = .005) in all those eyes that required ostial-IZHV. Conclusions : Ostial IZHV may be considered in eyes in a sub-group of glaucoma patients with high-risk characteristics for prevention of AM in the post-operative period. The anterior segment surgeon can successfully accomplish ostial-IZHV, effectively reducing dependence on a vitreo-retinal surgeon.

- Abstract
Purpose: The objective of this study was to investigate the efficacy and safety of phaco-endocycloplasty in an exclusive cohort of primary angle closure disease/glaucoma., Methods: The study was interventional and non-comparative, carried out at a tertiary level eye care Institute. All adult patients (> 18 years) with angle closure disease, who had controlled or uncontrolled intra-ocular pressure (IOP) and had visually significant cataract, requiring surgery, and had undergone phaco-endocycloplasty, performed for 180°-210° simultaneously with cataract surgery, were included., Main Outcome Measures: Primary outcome measure includes IOP, and secondary outcome measures include best corrected logMAR visual acuity (BCVA), anti-glaucoma medication (AGM) and complications., Results: Thirty-two eyes of 28 patients were included. Median follow-up was 15 months (range 3-42 months, Q1 7.5, Q3 18, IQR 10.5). Median IOP pre-procedure (20.5 mmHg, range 11-46, Q1 16.75, Q3 31, IQR 14.25) decreased significantly post-procedure at last follow-up (IOP 16 mmHg, range 10-20, Q1 12, Q3 17.5, IQR 5.5) (p < 0.001). There was significant decrease in use of AGM (median 3 pre-procedure, range 1-5, Q1 2, Q3 3.25, IQR 1.25) at last follow-up (median 0) (p < 0.001) post-procedure. Median logMAR BCVA improved from 0.4 (Q1 0.3, Q3 0.625, IQR 0.325) to 0.05 (Q1 0, Q3 0.3, IQR 0.3) at last follow-up (p < 0.001). None of the patients had serious sight-threatening complications., Conclusions: This study indicates that phaco-endocycloplasty can effectively control IOP, significantly reducing need for AGM, without compromising safety, in angle closure glaucoma. When combined surgery is indicated, this conjunctiva-sparing procedure may be employed in the management of coexisting cataract and glaucoma prior to bleb-forming surgery.

- Abstract
Purpose: The purpose of the study is to report the outcomes of simultaneous cataract extraction (CE) and a new nonvalved glaucoma drainage device (GDD), Aurolab Aqueous Drainage Implant (AADI), in eyes with cataract and refractory glaucoma., Methods: This was a non-comparative, interventional, retrospective study. Consecutive patients who underwent AADI together with phacoemulsification from June-2015 to January-2017 by a single fellowship trained glaucoma surgeon with documented 3-months of follow-up were included. The main outcomes were intraocular pressure (IOP), antiglaucoma medication (AGM), visual acuity, and complications., Results: We included 19 eyes of 17 patients with average follow-up of 14.4 ± 8.4 months. IOP and AGM reduced from 36.9 ± 11.1 mmHg and 4 ± 0.8 preoperatively to 12 ± 4.5 mmHg and 0.8 ± 1.2, respectively (P < 0.001). Complications were seen in seven eyes (36.8%). Total success was seen in 17 eyes (89.5%). None of the patients lost vision., Conclusion: Combining cataract extraction with the new non-valved Aurolab Aqueous Drainage Implant, appears to be an effective and safe technique in eyes with refractory glaucoma and cataract. Larger studies and further follow-up is recommended for such patients., Competing Interests: There are no conflicts of interest

- Abstract
Purpose: Previous studies have shown that iris mechanical properties may play a role in the pathophysiology of primary angle-closure glaucoma (PACG). Such studies, however, were not conducted in vivo and as such were limited in application and scope, especially for the development of diagnostic methods or new treatment options. The purpose of this study was to quantify in vivo iris mechanical properties both in patients with a history of angle-closure glaucoma and in healthy volunteers., Methods: We acquired optical coherence tomography scans of anterior segments under standard and dim light conditions. Using a combination of finite element simulation and an inverse fitting algorithm, we quantified the stiffness of the iris., Results: The irides in the eyes of patients with a history of PACG were significantly stiffer when compared with healthy control irides, a result consistent with ex vivo studies. This result was independent of the compressibility assumption (incompressible: 0.97 ± 0.14 vs. 2.72 ± 0.71, P = 0.02; compressible: 0.89 ± 0.13 vs. 2.57 ± 0.69, P = 0.02) when comparing the normalized elastic modulus of the iris between patients with PACG and healthy controls., Conclusions: Our noninvasive, in vivo quantification is free of numerous ethical issues and potential limitations involved with ex vivo examinations. If further studies confirm that the iris stiffness is an omnipresent PACG risk factor and a mechanistic role between increased iris stiffness and angle-closure glaucoma does exist, treatment methods such as lowering the iris stiffness can be developed.

- Abstract
Background: A new low-cost, indigenously manufactured, non-valved glaucoma drainage device (GDD) has been introduced and its design is based on the Baerveldt Glaucoma Device. We aim to demonstrate the efficacy and safety of this GDD (Aurolab aqueous drainage implant, AADI) vis-à-vis the valved device, Ahmed glaucoma valve (AGV), in the management of refractory glaucomas., Design: Retrospective, comparative, interventional., Participants: Case review of consecutive patients who underwent GDD surgery by a single fellowship-trained surgeon at a Tertiary Centre between January 2014 and November 2016., Primary Outcome Measure: Intraocular pressure (IOP)., Secondary: Antiglaucoma medication (AGM), LogMAR best-corrected visual acuity (BCVA), complications., Results: A total of 88 eyes of 83 patients were included; 36 eyes received AGV and 52 AADI. Preoperative parameters were similar between groups. Median follow-up was 13 and 12 months for AADI and AGV, respectively. Overall success rate was higher in AADI (92.3%) vs AGV (80.5%) (p<0.001). The median IOP in mm Hg (Quartiles; IQR) (AADI 14 (10,15;5) vs AGV 16 (14,20;6)) and AGM (AADI: 0 (0,1;1) vs AGV 2 (1,2.75;1.75)) was significantly lower in the AADI group at last follow-up (p<0.001). LogMAR BCVA improved in both groups; complication rates (AADI 44.2% vs AGV 52.7%) were comparable (p=0.59)., Conclusions: Both procedures were effective in reduction of IOP and need for AGM. Nevertheless, overall success rate was higher in the AADI group and IOP and number of AGM required was significantly lower in the AADI group; this affordable GDD could have a tremendous impact in the management of refractory glaucomas in low-income to middle-income countries., Competing Interests: Competing interests: None declared., (© Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

- Abstract
Purpose: The purpose of this study was to report the early outcomes in terms of efficacy and safety of a new, indigenously manufactured, low-cost nonvalved drainage device [AADI (Aurolab Aqueous Drainage Implant)] in the management of refractory glaucoma in the Indian population., Methods: Retrospective review of consecutive patients older than 12 years, who underwent glaucoma drainage device surgery (GDD) using AADI, by a single fellowship-trained surgeon, between January 2014 and December 2016, who had at least 3 months of documented post-op follow-up., Outcome Measures: Primary-intraocular pressure (IOP).Secondary-number of antiglaucoma medication (AGM), LogMAR best corrected visual acuity (BCVA), and complications.Complete success was defined as IOP ≥5 mm Hg and ≤21 mm Hg or reduction of IOP by ≥20% from baseline without AGM; qualified success with use of AGM. Failure was defined as inability to meet IOP criteria, loss of perception of light, explantation or any additional glaucoma surgery., Results: A total of 54 eyes of 51 patients were included. Mean follow up was 12.1±6.3 months. The IOP and number of AGM required was significantly lower at every visit postoperatively (P<0.001). Median LogMAR BCVA remained unchanged (P=0.5). Complications occurred in 22 patients (40.7%). Complete success was seen in 66.6%; overall success was 92.6%., Conclusions: New nonvalved GDD (AADI) surgery is effective in reducing IOP and need for AGM with a safety profile similar to published reports of prevailing GDDs. It thus has the ability to breach the cost barrier in low-to-middle income countries; further follow-up is required to determine sustainability over time.

- Abstract
Purpose: The aim of this study is to investigate the efficacy and safety of needling-revision augmented with a high dose of mitomycin C (MMC) in failing or failed blebs after trabeculectomy in Indian eyes., Methods: Prospective, noncomparative, interventional study. All patients (>18 years) who had raised intraocular pressure (IOP) following trabeculectomy (>6 weeks and <2 years), who had a flat bleb, bleb encapsulation, and/or required antiglaucoma medication (AGM) for IOP control were eligible for inclusion. MMC was injected subconjunctivally at least ½ hour before the needling procedure was carried out at the slit lamp in the outpatient's clinic., Results: Thirty-nine eyes of 38 patients were included. The median follow-up was 20 months and time interval between trabeculectomy and needle revision was 113 days. Initially, in all cases, aqueous flow was re-established with a raised bleb; 7 eyes required repeat needling. IOP decreased from median 24 mmHg (Q1 21, Q3 27, interquartile range [IQR] 6, range 18-35) preneedling to median 14 mmHg (Q1 10, Q3 16, IQR 6, range 6-18) postneedling at last follow-up (P < 0.0001, 95% confidence interval [CI]: 8.2-13.0). The use of AGM reduced from median 1 (Q1 0, Q3 3, IQR 3, range 0-4) preneedling to median 0 postneedling (P < 0.0001, 95% CI: 1-2). Complete success was seen in 28 eyes (71.8%, 95% CI: 71.1%-96.4%); another 5 eyes (12.8%) were controlled with AGM (qualified success) with overall success of 84.6%. Most complications were transient in nature with resolution within 1 week. One patient developed hypotony, and another developed a late bleb leak., Conclusion: Needling revision augmented with high-dose MMC, at the slit lamp, effectively rescues failing or failed filtration, and appears to be safe.

- Abstract
Aim: To obtain information on the prevailing practice patterns of glaucoma specialists in India., Methods: Glaucoma specialists attending the Annual Conference of the Glaucoma Society of India (GSI) were surveyed. This survey, conducted in 2013, was based on an interactive audience response system., Results: The information was obtained from 146 glaucoma specialists. Approximately half ( n =83; 57%) had ≥10y of experience in managing glaucoma and were in institutional practice ( n =74, 51%). Goldmann applanation tonometry was preferred by 103 (72%) specialists whilst n =25 (17.4%) used non-contact tonometer. Indentation gonioscopy was favoured by two-thirds ( n =90, 66%) whereas stereoscopic optic disc examination and visual fields using Humphrey perimeter was performed by a majority of the specialists surveyed ( n =115, 86% and n =114; 83% respectively). Nearly three quarter specialists ( n =96; 72%) preferred optical coherence tomography for imaging. The primary choice for treatment of angle closure disease and primary open angle glaucoma was laser (iridotomy, n =117; 93%) and medical management (prostaglandin analogue, n =104; 78%), respectively. Approximately only a third of the specialists surveyed ( n =37; 28%) were performing both trabeculectomy and implantation of a glaucoma drainage device and about half ( n =64; 47%) were not operating on congenital glaucoma at all., Conclusion: This survey has found conformance with preferred practice patterns in several areas of diagnosis and management of glaucoma, but there was diversity in a few areas. The information is a significant step towards improvement of glaucoma care in India, including planning for future strategies.

- Abstract
Purpose: The aim of this study is to explore and compare the prevailing practice patterns in the diagnosis and management of glaucoma among subspecialists and general ophthalmologists in India., Materials and Methods: This is an interactive audience response system (ARS) based poll of ophthalmologists attending the annual conference of the Glaucoma Society of India in 2013., Results: The information was obtained from 379 ophthalmologists (146 glaucoma specialists, 54 nonglaucoma subspecialists, and 179 general ophthalmologists). The majority of polled ophthalmologists (236; 62%) had 10 or more years of experience in ophthalmology. The glaucoma specialists differed from nonglaucomatologists in their preference for Goldmann applanation tonometer (P < 0.01), four-mirror gonioscope (P < 0.01), Humphrey perimeter (P < 0.01), laser peripheral iridotomy in primary angle closure disease (P = 0.03), postiridotomy gonioscopy (P < 0.01), and usage of antifibrotic agents during filtering surgery (P < 0.01). Optical coherence tomography was the most preferred imaging modality and was utilized more often by the subspecialists than general ophthalmologists. The ophthalmologists also differed in their choice of antiglaucoma medications. More glaucoma specialists were performing surgery on children with congenital glaucoma (P < 0.01), implanting glaucoma drainage devices (P < 0.01), and using scientific journals to upgrade knowledge (P = 0.03) than the other ophthalmologists., Conclusions: This poll is the first of its kind in India, in its usage of the ARS, and in comparing the practice patterns of care for glaucoma among subspecialists and general ophthalmologists. It has revealed substantial diversity in a few areas among those who did and did not receive specialty training in glaucoma., Competing Interests: There are no conflicts of interest.

- Abstract
Purpose: To compare the outcomes of cataract surgery alone versus combined cataract surgery with trabeculectomy in eyes with phacomorphic glaucoma., Materials and Methods: In a retrospective comparative case series, 126 eyes of phacomorphic glaucoma presenting within 4 weeks of onset between 1993 and 2012, with at least 6 months of postoperative follow-up were included. Group 1 included 63 eyes with cataract surgery only and group 2 included 63 eyes with combined cataract surgery and trabeculectomy. Primary outcome measure was intraocular pressure (IOP) ≤21 mm Hg (without antiglaucoma medication) 6 months after surgery., Results: The median (interquartile range) preoperative IOP in group 1 was 36 mm Hg (30 to 50 mm Hg) and group 2 was 40 mm Hg (32 to 48 mm Hg) (P=0.34). The median duration of phacomorphic attack was 7 days (3 to 12 d) in group 1 and 7 days (3 to 15 d) in group 2 (P=0.39). The median duration of postoperative follow-up was 23 months in group 1 and 30 months in group 2 (P=0.89). Six months after surgery, 97% of the eyes in group 1 and 100% in group 2 achieved IOP≤21 mm Hg without antiglaucoma medications with a median postoperative IOP of 12 mm Hg in both the groups (P=0.09). The median Log MAR visual acuity was significantly better in group 1 compared with group 2 (0.2 vs. 0.3, P<0.001). The percentage of eyes that achieved visual acuity better than 20/40 at 3 months was 62% in group 1 versus 19% in group 2 and at 6 months it was 75% in group 1 versus 38% in group 2 (P<0.001)., Conclusions: In our cohort of phacomorphic glaucoma presenting within 4 weeks of onset, cataract surgery and combined surgery resulted in similar IOP control at 6 months. However, cataract surgery alone resulted in better and faster visual recovery.

- Abstract
Purpose: We evaluated the utility values (UVs), using the time trade off (TTO) technique, associated with primary glaucoma and varying degrees of visual field (VF) loss., Methods: In this cross-sectional study, 198 adults (mean age, 59.8 years) with primary glaucoma were recruited from the glaucoma clinic of a tertiary center in Hyderabad, South India. Each patient underwent comprehensive glaucoma evaluation, and completed the utility (TTO) and Glaucoma Quality of Life-15 questionnaires (Rasch version, Glaucoma Activity Limitation [GAL]-10). Better mean deviation (MD, using Humphrey Field Analyzer program 24-2) between two eyes was used to classify participants into mild, moderate, and severe VF loss groups. Utilities (range, 0.0-1.0) derived by TTO technique (lifetime traded against perfect vision) and interval level Rasch scores of GAL-10 were used for analyses., Results: Mean UV was 0.81 (95% confidence interval [CI], 0.78-0.84); that is, a decrease in quality of life (QoL) of 19%. Of the subjects, 59% were willing to trade lifetime in return of perfect vision; those willing to trade were significantly younger with poorer acuity in the worse-seeing eye. In univariate and multivariate analysis, severe VF loss in the worse eye was associated with lower UV (β = -0.108; 95% CI, -0.201 to -0.014; P = 0.02)., Conclusions: Our results show that primary glaucoma in adults causes substantial decrease in UVs (and QoL thereof), and is highly dependent on the severity of VF loss in the worse eye.

- Abstract
Purpose: To evaluate the impact of glaucoma on visual functioning in Indians., Methods: Patients attending the glaucoma service who had undergone a comprehensive glaucoma evaluation were recruited. Better mean deviation (MD, using Humphrey Field Analyzer program 24-2) between two eyes was used to classify participants into mild, moderate, and severe visual field (VF) loss groups. Participants were administered the Glaucoma Quality of Life-15 (GQL-15) questionnaire. Rasch analysis was used to validate the GQL-15 and its four subscales. Linear regression was used to determine associations between GQL-15 scores and VF loss after adjusting for sociodemographic variables., Results: A total of 198 patients (mean age ± SD, 59.8 ± 12.3 years; 67% male) were recruited. Participants with severe VF loss (39%) followed by mild loss (35%) comprised the largest group. Rasch analysis resulted in a 10-item reliable and valid questionnaire: the Glaucoma Activity Limitation-10 (GAL-10). Although a single subscale, "peripheral vision," met requirements of the Rasch model, it could not be preserved in the GAL-10. In multivariate analyses, the middle-income group (compared with higher income) and severe VF-loss (compared with mild VF-loss) participants reported significantly poorer functioning on GAL-10 ([β = 0.84; 95% confidence interval (CI), 0.16-1.52; P = 0.02] and [β = 1.19; 95% CI, 0.61-1.78; P < 0.000], respectively). None of these associations were, however, clinically significant., Conclusions: Glaucoma patients in India, especially those with severe VF loss, face significant challenges in performing daily tasks and in mobility. It is important to prevent progression such that activity limitation is minimized in glaucoma patients.
