Abstract
Primary congenital glaucoma (PCG) occurs worldwide and has a broad range of ocular manifestations. It poses a therapeutic challenge to the ophthalmologist. A proper diagnostic evaluation under anesthesia is advisable for all children who do not cooperate for an office examination. Medical therapy only serves as a supportive role, and surgical intervention remains the principal therapeutic modality. Angle incision surgery such as goniotomy or trabeculotomy ab externo is the preferred choice of surgery in the Caucasian population. Primary combined trabeculotomy-trabeculectomy with or without antifibrotic therapy is the preferred choice in certain regions such as India and the Middle East where the disease usually presents with severe forms of corneal edema along with megalocornea. In refractory cases, trabeculectomy with antifibrotic therapy or glaucoma drainage devices are available options in the armamentarium. Cycloablative procedures should be reserved for eyes with poor visual potential. Myopia is common among children with PCG, and appropriate optical refractive correction in the form of glasses or contact lenses should be provided. Amblyopia therapy should be instituted to ensure overall visual development in the early developmental years. Low-vision rehabilitation services should be provided to children with vision impairment. Long-term follow-up is mandatory and carers of children with PCG should be counseled and educated about this need. Regardless of the visual outcomes, clinicians should emphasize the need for education of these children during the clinic visit. The overall goal of the management should be to improve the overall quality of life of the children with PCG and their carers.

Abstract
PURPOSE To assess the outcomes of the non-valved Aurolab aqueous drainage implant (AADI) in neovascular glaucoma (NVG). METHODS Data of consecutive patients with NVG who underwent AADI and had a minimum follow-up of 2 years were included. The primary outcome measure was the cumulative rate of surgical failure defined as intraocular pressure (IOP) >21 mm Hg or reduced <20% below baseline, IOP ≤5 mm Hg, reoperation for glaucoma or a complication, or loss of light perception vision. RESULTS We included 85 eyes of 85 patients with NVG, with a mean age of 61.2±9.3 years. The most common aetiologies were proliferative diabetic retinopathy (n=43) and central retinal vein occlusion (n=24). The mean IOP decreased from 36.8±12.5 mm Hg at baseline to 15.8±7.5 mm Hg at 2-year follow-up (p<0.001) and the number of IOP-lowering medications reduced from 3.4±0.8 to 1.5±1.1 (p<0.001). The cumulative rate of failure increased from 3.1% (95% CI 1.1% to 11.8%) at 1 year to 33.8% (95% CI 20.4% to 52.5%) at 2 years. Multivariable analysis showed that eyes with open angles had a lower risk of failure (HR 0.17, 95% CI 0.10 to 1.03, p=0.09). The logarithm of minimum angle of resolution visual acuity declined from 0.98±0.7 to 1.8±1.0 at 2 years (p<0.001). CONCLUSION Approximately one-third of NVG eyes that received the AADI failed after 2 years of follow-up similar to other series. Early AADI implantation at the open angle stage of NVG may yield better results.

Abstract
BACKGROUND Ahmed glaucoma valve (AGV) is a common surgical method for the treatment of refractory glaucoma.Aurolab aqueous drainage implant (AADI) is a novel surgical method which has been applied in clinical practice in recent years. OBJECTIVE The purpose of this study was to compare the efficacy and safety of the AADI and the AGV for the treatment of refractory glaucoma. METHODS We comprehensively searched four databases, including PubMed, Embase, Web of Science, and the Cochrane Library databases, selecting the relevant studies. The continuous variables, namely, intraocular pressure reduction (IOPR) and a reduction in antiglaucoma medication (AGMR), were pooled by the weighted mean differences (WMDs), and the dichotomous outcomes, including success rates and complications, were pooled by the odds ratio (OR). RESULTS A total of 825 eyes from 820 patients from six studies were included. The WMDs of the IOPR between the AADI and the AGV implant were 0.58 (95% CI: 0.07-1.09) at 3 months, 0.44 (95% CI: 0.11-0.77) at 6 months, 2.20 (95% CI: 0.63-3.77) at 12 months, and 3.24 (95% CI: 1.73-4.75) at follow-up endpoint. Significant difference was detected between the two groups at any point in time. The WMDs of the AGMR between the AADI and the AGV implant were 0.87 (95% CI: 0.61-1.13) at 6 months, 1.04 (95% CI: 0.66-1.42) at 12 months, and 0.93 (95% CI: 0.52-1.34) at the follow-up endpoint; the differences reached statistical significance at any point in time. The pooled ORs comparing the AADI with the AGV were 3.64 (95% CI: 2.44-5.45) for the complete success rate and 1.72 (95% CI: 1.24-2.39) for qualified success rate; significant difference was detected between the two groups. There were no significant differences between the AADI and the AGV implant on the rates of adverse events. CONCLUSIONS The AADI is more effective in both its surgical success rate and reducing IOP and AGM. And the two implants may have comparable incidences of adverse events.

Abstract
PURPOSE The purpose of this review is to place together all the knowledge available on aurolab aqueous drainage implant (AADI) in one place for the benefit of all glaucoma specialists who are interested in low-cost implants in developing world with desired results. METHODS A comprehensive literature search was done on AADI and its use in glaucoma management. 35 results were obtained from the literature search. Out of these 35, 2 were commentaries, 6 were case reports and rest 27 were studies (prospective and retrospective) discussing the surgical outcomes, modifications and comparison of AADI with other glaucoma drainage devices (GDDs). Out of these, 2 commentaries were excluded and rest 33 articles were included, cited and discussed appropriately in this review. RESULTS AADI resulted in a significant reduction in the intra ocular pressure (IOP) and also in the number of antiglaucoma medications. AADI can be implanted alone or combined with cataract surgery. It was found to be beneficial in both pediatric and adult refractory glaucoma. There was no significant difference seen in the pre and post operative visual acuity. But AADI was also associated with various hypotony related and tube related early and late onset complications. Some of these complications were managed conservatively and some needed surgical intervention. CONCLUSIONS AADI is a low-cost non-valved GDD with successful results in both adult as well as pediatric refractory glaucomas. Early and late onset complications are common and can be managed with appropriate and timely medical or surgical intervention.

Abstract
PURPOSE The aim was to investigate intraocular pressure (IOP) control after phacoemulsification in adult glaucomatous eyes with a functioning nonvalved Aurolab Aqueous Drainage Implant (AADI) compared with eyes that did not have cataract extraction post-AADI. METHODS In this retrospective study, we reviewed records of 47 patients (47 eyes) who had a clear corneal phacoemulsification after AADI placement with a minimum of 2 years of follow up. The control group included 89 patients (89 eyes) who had a functional AADI at 1 year, minimum of 3 years of follow up post-AADI implantation, and no cataract extraction. The main outcome measure was failure (IOP >21 mm Hg or increased by >20% from prephacoemulsification level requiring at least 1 additional glaucoma medication, IOP ≤5 mm Hg, reoperation for glaucoma, or loss of light perception vision). RESULTS The median interval between AADI and phacoemulsification was 11.5 months (range: 4 to 68 mo), and the mean follow-up time after phacoemulsification was 35.6±6.4 months. The cumulative probability of failure was 14% (95% confidence interval=6%-31%) in the phaco group and 6% (95% confidence interval=3%-13%) in the control group at 2 years (P=0.11). Mean IOP was reduced from 16.5±4.5 mm Hg preoperatively to 15.4±4.7 mm Hg at 2 years after phacoemulsification (P=0.10). Mean LogMAR visual acuity improved from 1.1±0.6 preoperatively to 0.6±0.7 at 2 years after phacoemulsification (P<0.001). CONCLUSIONS In eyes with a pre-existing AADI, phacoemulsification resulted in visual improvement without a significant rise in IOP or increased risk of AADI failure after 2 years follow up.

Abstract
Objective The Aurolab aqueous drainage implant (AADI) has the potential advantages of less encapsulation and greater cost-effectiveness than the Ahmed glaucoma valve (AGV). The aim of this study was to compare the surgical success and outcomes of the AADI compared to the AGV in Middle-Eastern children. Methods A comparative retrospective study of consecutive paediatric patients in a tertiary eye hospital was undertaken. Data collected included demographics, type of glaucoma, intraocular pressure (IOP), number of anti-glaucoma medications (AGMs) and any subsequent complications or further surgeries. Analysis The mean IOP, number of AGMs, surgical success and number of reoperations was compared for the two groups. Surgical success at each visit was defined as IOP of ≥6 mm Hg and ≤21 mm Hg or if the reduction of IOP was ≥20% reduced from baseline. Results A total of 126 tube surgeries (56 eyes in AADI and 70 eyes in AGV) were performed in patients aged ≤18 years from 2014 to 2019. No difference was observed in the mean IOP between the two groups except at the first month post-operative visit. After six months, the AADI group had a consistently significant lower mean number of AGMs. At last follow-up, 21 (37.5%) eyes in the AADI group were glaucoma medication-free vs 15 (21.4%) eyes in the AGV group (pp=0.047). Kaplan-Meier analysis showed equivalent cumulative probability of success at two years of 69.9% [(45.9%–84.9%)] for AADI vs 66.8% [(53.4%–77.1%])) for the AGV, respectively. Twenty-four eyes in the AGV group needed one or more subsequent surgeries, whereas 13 eyes needed one or more surgery in the AADI group. Conclusions This study shows an acceptable safety profile for the AADI in children, with a rate of failure that is comparable to the AGV, but less need for glaucoma re-operation or glaucoma medication in the first post-postoperative year.

Abstract
PURPOSE To report the clinical outcomes of glaucoma management in patients with phacomatosis pigmentovascularis (PPV) treated over a period of 3 decades. DESIGN Retrospective cohort study. PARTICIPANTS Fifty-five eyes of 38 patients (21 unilateral and 17 bilateral) with glaucoma in PPV managed at one institution between January 1990 and December 2019 with a minimum follow-up of 1 year. METHODS Medical records of children with glaucoma in PPV were reviewed, and demographic and clinical data were collected. Surgical interventions included primary combined trabeculotomy-trabeculectomy (CTT), trabeculectomy with mitomycin C (MMC), and transscleral cyclophotocoagulation (TSCPC). Complete success was defined as intraocular pressure (IOP) ≥ 6 and ≤ 16 mmHg without medications and qualified success as IOP ≤ 16 mmHg with the use of up to 2 medications. MAIN OUTCOME MEASURES Intraocular pressure, best-corrected visual acuity (BCVA), corneal clarity, antiglaucoma medications at preoperative and postoperative visits (last visit), and complications. RESULTS Median age was 4 months (range, 0.2-252 months) at the time of glaucoma surgery. Thirty-nine eyes (74%) had primary CTT, 10 eyes (19%) had trabeculectomy with MMC, and 4 eyes (7%) with advanced glaucoma had TSCPC. Two eyes (3.6%) received medical treatment. Preoperative IOP reduced from a mean of 25.7 ± 8.4 mmHg on 0.8 ± 0.6 medications to 14.6 ± 5.2 mmHg on 0.4 ± 0.5 medications (P < 0.0001) at last follow-up after surgery (77.7 ± 56.5 months). Thirty-seven eyes (67.3%) required medications preoperatively, and 22 eyes (40%) required medications at the last follow-up. Of 25 patients with available BCVA at last follow-up, 9 (36%) had ≥ 20/60; of these, 6 had > 20/40. Four of 10 eyes that underwent trabeculectomy with MMC developed retinal detachment and were managed surgically; however, all of these eyes had poor visual outcomes. There was no incidence of bleb leakage, bleb-related infection, or endophthalmitis. CONCLUSIONS Combined trabeculotomy-trabeculectomy is safe and effective as a primary procedure for management of glaucoma in PPV. Trabeculectomy augmented with MMC as a second procedure was associated with a higher rate of complications.

Abstract
PRCIS Postoperative suprachoroidal hemorrhage (PSCH) is an infrequent but devastating complication after nonvalved aqueous drainage implant surgery and demonstrated a bimodal distribution. The final outcomes of either conservative management or surgical drainage of the hemorrhage remained poor. PURPOSE The aim was to report the incidence and outcomes of eyes developing PSCH after undergoing Aurolab aqueous drainage implant (AADI) surgery for adult and pediatric refractory glaucomas. MATERIALS AND METHODS In this retrospective series, case files of all patients who underwent AADI between May 2012 and December 2019 were retrieved from an electronic database. A PSCH was defined as the presence of hemorrhagic choroidal detachment, confirmed by ultrasound B scan, occurring in a closed system in the postoperative period. RESULTS Of the 986 eyes that underwent AADI during the study period, 7 (0.7%), developed PSCH (95% confidence interval=0.3-1.6%). There were no differences in the preoperative parameters between those with and without PSCH. Of these, 4 were seen in pediatric eyes (4/288, 1.4%) and 3 in adult eyes (3/698, 0.4%) (P<0.01). Four eyes (57%) had PSCH in the immediate postoperative period (ie, between 24 and 48 h of AADI surgery), while the remaining 3 had onset ranging from 6 to 7 weeks after surgery. Anatomic risk factors were present in all eyes including hypotony (n=4), myopia (n=3), microcornea (n=2), microphthalmos (n=1), postvitrectomy (n=1), and staphyloma (n=1). Visual acuity improved in only 1 (14%) eye while 3 (43%) eyes developed phthisis bulbi, all in the pediatric age group. CONCLUSIONS PSCH is a rare complication following AADI and is seen in <1% eyes. The incidence is higher in the pediatric age group. Visual and anatomic outcomes are dismal following PSCH with globe salvage possible in only about half these eyes.
