ABSTRACT

PRCIS: In eyes with Sturge-Weber syndrome (SWS) with early onset glaucoma, primary combined trabeculotomy with trabeculectomy (CTT) had a good intermediate-term success rate and minimal postoperative complications. DESIGN: Retrospective cohort study. OBJECTIVE: To report the intermediate-term outcomes of primary CTT in early onset glaucoma with SWS. PATIENTS AND METHODS: This study included 49 eyes of 49 children (1997-2020) with SWS and early onset glaucoma who underwent primary CTT with at least 1-year postoperative follow-up. Success was defined as complete when intraocular pressure was >5 mm Hg and ≤16 mm Hg under general anesthesia or ≤21 mm Hg in the clinic without antiglaucoma medications (AGMs) and as qualified with AGM. RESULTS: The median age (interquartile range) at CTT was 0.58 (0.19, 8.3) years. The median postoperative follow-up was 4.7 years (2.5, 9). The majority were male children (31/49, 63%). Epilepsy was noted in 7 (14.3%) and diffuse choroidal hemangioma in 17 children (35%). At diagnosis, 37 eyes(75%), had corneal edema, and the mean (±SD) horizontal corneal diameter was 12.8 ± 0.7 mm. Postoperatively, the median intraocular pressure decreased from 26 (22, 30) mm Hg to 16 (12, 20) mm Hg ( P < 0.0001) and the median number of AGM reduced from 1 (0,1) to 0 (0,1; P < 0.01). Complete success probability of CTT was 86% (76, 96) at 1 year and 64% (49, 84) at 5 years. Qualified success was 98% (94, 100) at 1 year and 89% (78, 100) at 5 years. A larger cup-to-disk ratio ( P < 0.005) was associated with a higher risk of surgical failure. Postoperative complications were noted in 9 eyes (18%), all resolved with conservative management except one eye with a retinal detachment that ended in phthisis bulbi. CONCLUSION: CTT as a primary procedure showed good long-term efficacy and safety in SWS with early onset glaucoma.

ABSTRACT

Purpose: To describe the clinical outcome of a series of seven eyes with an explanation of an original Glaucoma Drainage Device (GDD) arising from the complication of plate exposure and consequent reimplantation of another GDD at a second setting. Methods: This was a retrospective, interventional, and non-comparative study at two tertiary eye care hospitals in eastern and southern India. Electronic medical record data of the seven eyes where a GDD was explanted and a 2nd GDD was reimplanted over October 2010 and May 2021 was analyzed. Statistical analysis was done by SPSS (ver. 26). Results: The first GDD survived for a mean of 168 days only till the plate got exposed and thereby got explanted. Possible predisposing factors noted were conjunctival and scleral thinning, ischemic conjunctiva, etc., The reimplantation surgery was technically easy in the absence of hypotony-opposite to what is reported in the literature. The final IOP (mean +/- SD) values (mm Hg) were 18.9 (+/-7.9), range = 10-30. The mean number of glaucoma medications reduced from 3.9 (+/-1.2; range, 2 to 5) after the explanation to 3.1 (+/-0.7; range, 2 to 4) after the 2nd GDD implantation, in the final follow-up. The second GDD was found to be stable till the last follow-up (mean = 1149 days). No other significant intraoperative or postoperative complications were seen. Conclusions: Reimplantation of a second GDD in a separate setting after explanations of an original implant due to exposure-related complication is both a safe and effective method.

ABSTRACT

Purpose: To compare image characteristics of retinal nerve fiber layer (RNFL) between glaucoma patients and healthy controls using adaptive optics scanning laser ophthalmoscopy (AOSLO). Methods: This was a cross-sectional pilot study with two groups: a glaucoma group with patients with moderate or severe glaucoma as per the Hodapp-Parrish-Anderson classification system and a control group with healthy individuals. The optic nerve damage in moderate glaucoma was predominantly located in only one hemisphere; the other hemisphere was un- or minimally affected on optical coherence tomography and automated perimetry and is referred to as early glaucoma. The structure of RNFL bundles and gain (%) in RNFL images with mean pixel values between 15 and 35 were analyzed. Imaging was performed one degree away from the optic disc margin at two and four cardinal clock positions in the glaucoma and control groups, respectively. The field of view was 1.3° at 2.3 µ resolution. We studied one eye per participant. Results: There were 11 glaucoma patients and 7 healthy controls. Imaging was successful at 88% of the locations in controls and early glaucoma; the reflectivity differed significantly (0.51 and 0.56, respectively, P < 0.001) but not the structure of RNFL bundles (Cohen's Kappa 0.11) between them. In patients with moderate and severe glaucoma, imaging was successful only at 46% of the locations; RNFL bundles were not discernible, and RNFL reflectivity did not differ from those with early glaucoma (P < 0.11). Conclusion: The recorded gain (%) of RNFL images obtained using AOSLO could be an objective indicator of early glaucoma.

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: To report outcomes and assess the risk factors for failure of trabeculectomy (trab), trabeculectomy with mitomycin-C (trabMMC), and combined trabeculectomy with cataract extraction (CT) in vernal keratoconjunctivitis (VKC) eyes with steroid-induced glaucoma (SIG). METHODS: Trab was performed in 45 eyes of 30 subjects, trabMMC in 36 eyes of 25 subjects, and CT in 34 eyes of 27 subjects. Success was complete when intraocular pressure (IOP) was between 6 and 21 mm Hg without anti-glaucoma medications (AGM) and qualified with AGM. RESULTS: Median age (14 vs. 16.3 and 17.4 years) was significantly less in the trab cohort (P = 0.007). Majority (88%-93%) were male (P = 0.78). Preoperatively, median duration of steroid usage was >2 years (P = 0.52), mean IOP (32, 29.4, and 28.4; P = 0.26) and median cup:disc ratio (CDR) (0.9; P = 0.27) were similar in the three groups. Complete success (76%, 71%, and 66% at 5 years; P = 0.91), and qualified success (88%, 97%, and 94% at 5 years; P = 1.0) with trab, trabMMC, and CT, respectively, were similar. Preoperative factors significantly associated with qualified failure (multiple logistic regression) were older children, longer duration of VKC, longer duration and mixed type of steroid use (all P < 0.001) and larger CDR (P < 0.02). At the last follow-up, 38% in trab, 33% in trabMMC, and 50% eyes in CT were blind (visual acuity ≤20/400 and/or visual field ≤10°) due to glaucoma (P = 0.33). CONCLUSION: The surgical success for all three types of surgery was similar at 5-years. Chronic VKC and long-term steroid use were associated with surgical failure. The majority had advanced disease and a significant proportion were blind due to glaucoma.

ABSTRACT

PURPOSE: To report the outcomes of trabeculectomy in eyes with refractory acute primary angle-closure attack. METHODS: Patients with acute primary angle-closure attack and who underwent trabeculectomy for medically uncontrolled intraocular pressure within 2 months of presentation were retrospectively analyzed. Primary outcome was intraocular pressure (IOP). Secondary outcome measures were visual acuity, number of antiglaucoma medication (AGM), complications, and risk factors for failure of trabeculectomy. RESULTS: Thirty-five eyes of 31 patients with median (interquartile range) follow-up of 3 (0.5, 9) years were included in the study. Median age at presentation was 55 (47, 60) years. Median duration of symptoms at presentation was 10 (4, 16) days and median time from presentation to surgery was 13 (6, 25) days. Median IOP reduced from 42 (36, 46) to 13 (12, 16) mmHg (P < 0.001) and median number of AGM reduced from 3 (1, 3) to 0 (0, 0) after trabeculectomy at the end of 1 year. The probability of complete and qualified success was 88% (95% confidence interval [CI]: 72%-95%) and was 97% (95% CI: 81%-99%) at 1 year, respectively. Failure was noted in six eyes. Subsequent cataract surgery was needed in 13 eyes (37%) with a median duration from trabeculectomy being 6.75 (1, 11) years. None of the preoperative, intraoperative, or postoperative factors tested were associated with failure (P > 0.10 for all associations on Cox proportional hazard regression analysis). CONCLUSION: In medically unresponsive cases of acute primary angle-closure attack, primary trabeculectomy seems safe and effective in Indian eyes.

ABSTRACT

PURPOSE: To evaluate the outcomes of trabeculectomy in the eyes with neovascular glaucoma (NVG), caused by proliferative diabetic retinopathy (PDR), central retinal vein occlusion (CRVO), and ocular ischemic syndrome (OIS). METHODS: A retrospective review of NVG eyes that underwent trabeculectomy between 1991 and 2019. Complete success was defined as intraocular pressure (IOP) between 6 and 21 mmHg without antiglaucoma medications (AGM). The risk factors were analyzed by Cox's proportional hazard model. RESULTS: The study included 100 eyes of 100 subjects with a mean age of 58 ± 9.8 years and a median follow-up of 1.27 years (interquartile range: 0.63, 2.27). The cause of NVG was PDR in 59 eyes (59%), CRVO in 25 eyes (25%), and OIS in 16 eyes (16%). Trabeculectomy with mitomycin-C was performed in 88 eyes and trabeculectomy in 12 eyes. The cumulative complete success probability of trabeculectomy in PDR was 50% (95% confidence interval [CI]: 38, 65) at 1 year, 8% (1, 46) at 3-5 years. In OIS, it was 64% (43, 96) from 1 to 5 years. In CRVO, it was 75% (59, 94) at 1 year, 45% (23, 86) from 2 to 5 years. The PDR was associated with a higher risk of surgical failure compared to OIS (P = 0.04) and CRVO (P = 0.004). Other significant risk factors were increasing age (P = 0.02), persistent neovascularization of iris (NVI) (P = 0.03), higher number of anti-vascular endothelial growth factor (VEGF) injections prior to trabeculectomy (P = 0.02), and delay in performing trabeculectomy (P = 0.02). CONCLUSION: Compared to CRVO and OIS, the eyes with NVG secondary to PDR had poor success with trabeculectomy. Older age, persistent NVI, need for a higher number of anti-VEGF injections, and delayed surgery were associated with a higher risk for trabeculectomy failure.

ABSTRACT

PURPOSE: The aim of this study was to report our initial experience on the outcomes of phacoemulsification in combination with goniotomy using the Kahook Dual Blade (KDB) in eyes with advanced open-angle glaucoma (OAG). METHODS: The outcomes of phaco-goniotomy with KDB in advanced OAG in Indian eyes were retrospectively analyzed. Based on the Hodapp-Anderson-Parrish criteria of visual field defects, severe glaucoma (mean deviation on standard automated perimetry worse than 12 dB) was considered as advance glaucoma. Preoperative, intraoperative, and postoperative data were collected through 6 months of follow-up. Outcome measures included antiglaucoma medications (AGM), the proportion of eyes achieving >1AGM reduction, intraocular pressure (IOP), and visual acuity. RESULTS: Median (interquartile range) number of AGM in eyes that underwent phaco-KDB goniotomy reduced from 2 (2,3) at baseline to 1 (0,1) at 6 months (P = 0.002). Median IOP reduced from 20 (20,26) mmHg at baseline to 14 (12,15) mmHg at 6 months (P = 0.02). The proportion of eyes achieving >1 medication reduction was 88% eyes (8/9). Adverse events noted were IOP spike (22 mmHg) in 2 eyes and intra-op hyphema in 1 eye on postoperative day-1, both resolved in a week with conservative management. Except one eye with central corneal scar due to prior pterygium surgery, 8 eyes had 20/20 vision at 1 week which was maintained till last follow-up. CONCLUSION: Phacoemulsification with KDB Goniotomy significantly lowered the need for AGM with moderate IOP reduction in advanced OAG eyes. There were no serious complications and the visual recovery was good and early.

ABSTRACT

We report a case of a 7-year-old boy, who presented with plate exposure after Ahmed glaucoma valve (AGV) implantation in the eye with secondary glaucoma following penetrating trauma. He underwent AGV explantation with scleral patch graft and conjunctival limbal autograft and started on topical and oral antiglaucoma medication (AGM) for intraocular pressure (IOP) control. Two months later, he presented to us with high intraocular pressure and uveal tissue prolapse at the site of previous tube entry displacing the scleral and conjunctival grafts posteriorly. The defect was closed with corneal patch graft. Patient underwent limited transscleral cyclophotocoagulation and was maintained on topical AGM for IOP control. Our case highlights that explantation is a definitive management in such cases of plate exposure. Tube entry site is a potential weak area and there is risk of uveal prolapse through this area with high IOP. Corneal patch graft helps in successfully managing such defects involving the sclero-limbal region.

ABSTRACT

PURPOSE: To report clinical features and treatment outcomes of primary combined trabeculotomy with trabeculectomy (CTT) in congenital aniridia with glaucoma in children 3 years of age or younger. DESIGN: Retrospective study. PARTICIPANTS: Sixty-six eyes of 35 children with congenital aniridia and early-onset glaucoma who underwent CTT between May 1997 and June 2015 were included. METHODS: Success was defined as complete when intraocular pressure (IOP) was more than 5 mmHg and less than or equal to 21 or 16 mmHg without antiglaucoma medications (AGMs), and qualified when AGMs were required. Eyes needing repeat surgery for IOP control were considered as failures. MAIN OUTCOME MEASURES: IOP control and number of AGMs. RESULTS: The median age at presentation of 35 children was 26 days (interquartile range [IQR], 7-106 days). There were 22 males (62.9%) and 13 females (37.1%). Parental consanguinity was noted in 11 children (31.4%). Aniridia was total in 52 eyes and partial in 14 eyes. At presentation, there was corneal edema in 30 eyes (45.4%), enlarged corneal diameter in 32 eyes (48.5%), nystagmus in 15 children (23%), limbal stem cell deficiency in 1 eye, cataract in 9 eyes (13.6%), and foveal hypoplasia in 4 eyes. After CTT, median IOP was reduced significantly (P < 0.0001). Corneal edema cleared in 12/30 eyes and cleared with scar in 18/30 eyes. Median follow-up was 5.33 (IQR, 3.05-7.59) years. At latest follow-up, median number of AGMs was 1 (IQR, 0-2) and median visual acuity in logarithm of minimum angle of resolutions (n = 34 eyes) was 1.35 (IQR, 0.80-2.78). The probability of complete success for IOP ≤ 21 mmHg was 79.9% at 1 year and 62.3% between 2 and 10 years; for IOP ≤ 16 mmHg, it was 78.6% at 1 year and decreased to 51.9% at 10 years. Qualified success for IOP ≤ 21 mmHg at 1 year was 82.6% and 81% over 10 years; for IOP ≤ 16 mmHg, it was 81.4% at 1 year and decreased to 63.1% at 10 years. Seven eyes (10.6%) required repeat intervention for IOP control with median time of 3.17 years (IQR, 0.92-6.56) from first surgery. CONCLUSIONS: CTT showed good success in children with congenital aniridia with early-onset glaucoma.

ABSTRACT

PRECIS: Preoperative intravenous (IV) dexmedetomidine produced a 33% reduction in intraocular pressure (IOP) within 15 minutes of administration in patients with glaucoma. PURPOSE: To evaluate the effect of preoperative IV dexmedetomidine on IOP in adult patients undergoing glaucoma surgery under local anesthesia. METHODS: In a prospective interventional case series, 12 patients with uncontrolled IOP (IOP>24 mm Hg in both the eyes) with the systemic status of American Society of Anesthesiologists (ASA) classification I-II, received IV dexmedetomidine 0.6 µg/kg 30 minutes preoperatively. The IOP of the nonsurgical eye (measured with Perkins tonometer), the heart rate (HR), and blood pressure (BP) were recorded 5 minutes prior, 15 minutes and 2 hours after IV dexmedetomidine administration, and were compared using analysis of variance and Tukey honestly significant difference tests. RESULTS: There were 4 women and 8 men with a mean age (±SD) of 60.6±10.4 years. The mean number of antiglaucoma medications was 4.3±1.3. The mean pre-dexmedetomidine IOP was 31.5±5.6 mm Hg. At 15 minutes post-dexmedetomidine administration, the mean and percentage drop in IOP were 10.2±3.2 mm Hg (P=0.001) and 33%±11%, respectively. The mean and percentage drop in systolic BP were 18±20 mm Hg (P=0.01) and 12%±14%, and drop in diastolic BP were 6.5±10 mm Hg (P=0.05) and 7%±11%, respectively. The mean and percentage drop in HR were 2±0.6 bpm (P=0.48) and 2%±13%, respectively. None of the subjects experienced any medication-related adverse effects. At 2 hours, the mean and percentage drop in IOP were 5.3±3 mm Hg and 17%±11%, respectively. CONCLUSION: In the small sample of (ASA I-II) patients studied, preoperative dexmedetomidine produced a significant drop in IOP (33%) within 15 minutes of IV administration in patients with glaucoma that was reversing at 2 hours, with a good safety profile.

ABSTRACT

PURPOSE: To discuss the clinical presentation and management of intraocular tumors masquerading as primary glaucoma or non-tumor-related secondary glaucoma. METHODS: Retrospective chart review. RESULTS: Ten patients with unsuspected intraocular tumor were referred to glaucoma clinic with a diagnosis of primary glaucoma or non-tumor-related secondary glaucoma. The mean age at referral was 25 years (median, 22 years; range, 1 day to 58 years). Referral diagnosis included neovascular glaucoma (n = 6), congenital glaucoma (n = 3), and angle-closure glaucoma (n = 1). The significant clinical signs included corneal edema (n = 3), megalocornea (n = 3), iris neovascularization (n = 4), hyphema (n = 2), and pseudohypopyon (n = 2). The mean interval between the onset of symptoms and the establishment of accurate diagnosis was 4 months (median, 3 months; range, 0.5-13 months). Two patients underwent inadvertent trabeculectomy, and one patient underwent evisceration prior to definitive diagnosis. The final diagnosis included uveal melanocytoma (n = 2), ciliary body medulloepithelioma (n = 2), choroidal melanoma (n = 2), retinoblastoma (n = 1), retinal capillary hemangioblastoma (n = 1), choroidal schwannoma (n = 1), and uveal metastasis (n = 1). The treatment modalities included plaque radiotherapy (n = 1), enucleation (n = 6), palliative systemic chemotherapy (n = 1), a combination of enucleation, systemic chemotherapy, and external beam radiotherapy (n = 1), and one patient was lost to follow-up. There was no evidence of death over a mean follow-up period of 13 months (median, 5 months; range, 2 weeks to 7 years). CONCLUSION: Unilateral raised intraocular pressure, iris neovascularization, or both may be the presenting features of intraocular tumors. High degree of suspicion and a thorough examination reveals the definitive diagnosis.

ABSTRACT

We report the case of a 64-year-old pseudophakic patient in a rural area who chronically suffered from headache with eye pain and was on analgesics for pain relief but never turned up to an ophthalmologist. There was lack of awareness to visit an ophthalmologist for headache as he thought that after undergoing cataract surgery, the role of ophthalmologist was limited. His approach to our centre was only after intense headache with sudden loss of vision. He had actually developed secondary glaucoma due to pupillary block angle closure as a late complication following yttrium aluminium garnet capsulotomy. After medical and surgical management, he regained his complete vision with total relief from headache.

ABSTRACT

PURPOSE: To study the agreement between scleral intraocular pressure (IOP) measurements using the Schiotz, Icare, and Icare PRO tonometers versus Goldmann applanation tonometer (GAT) in eyes with nonscarred corneas. METHODS: This cross-sectional study included 83 eyes of 55 subjects. The order of IOP estimation was the corneal GAT, followed by ICare, ICare PRO, and Schiotz on the corneal and temporal sclera. The agreement between different tonometers and the 95% limits of agreement (LoA) were assessed using Bland-Altman plots. The repeated measures correlation coefficient was calculated between GAT IOP and scleral Schiotz IOP, and the 95% confidence intervals were calculated by the bootstrap method. The linear mixed effects model was used (adjusted for both eyes of the subjects) to generate an equation to predict GAT IOP from scleral Schiotz IOP. The prediction model was validated with new data from 60 eyes. Statistical analyses were performed using "R" software (version 3.3.2). RESULTS: Comparing the scleral IOP measurements, the mean IOP difference (95% LoA) was the lowest with Schiotz, underestimating by -1.21 mm Hg (7.32, -9.74). Both ICare and ICare PRO significantly overestimated GAT IOP: ICare, 24.6 mm Hg (53.2, -3.97); and ICare PRO, 21.56 mm Hg (52.9, -9.79). The correlation coefficient between scleral Schiotz and GAT IOP was 0.92 (95% bootstrap confidence interval: 0.89, 98). The derived predictive equation was (Equation is included in full-text article.). The mean difference between the predicted GAT IOP and the actual GAT IOP was 0.96 mm Hg with narrow LoA (+1.79, -3.71), validating the prediction model. CONCLUSIONS: Among the tonometers tested, the scleral IOP measurements with Schiotz had the best agreement with the GAT although LoA were wide. The predictive equation may have great potential to predict GAT IOP from scleral IOP readings in eyes with scarred/prosthetic corneas.

ABSTRACT

PURPOSE: To describe the prevalence of various types of childhood glaucomas, their clinical features and treatment methods. METHODS: We prospectively included consecutive children with glaucoma presenting to glaucoma clinic for the first time between March 2013 and May 2014. We classified childhood glaucomas as per the classification proposed by Congenital Glaucoma Research Network. RESULTS: Of the 275 children (449 eyes) with glaucoma during this period, primary glaucomas constituted 56% (n = 252 eyes of 145 children), including 169 eyes (37.64%) of 97 children with primary congenital glaucoma (PCG), 16 eyes (3.56%) of 10 children with infantile glaucoma, and 67 eyes (14.9%) of 38 children with juvenile open angle glaucoma. Among these, 85% (214 eyes of 107 children) had bilateral involvement. Secondary glaucomas constituted 44%; they were glaucoma associated with ocular anomalies 18% (n = 80 eyes), glaucoma associated with acquired conditions (steroid induced and traumatic glaucoma) 14% (n = 61 eyes), glaucoma following congenital cataract surgery 7.6% (n = 34 eyes), and glaucoma associated with systemic or syndromic conditions 5% (n = 22 eyes). In primary glaucomas, boys and girls were equally affected (1:1), and more boys (3.8:1) had acquired glaucomas. Close to 80% PCG eyes were managed surgically with combined trabeculotomy and trabeculectomy (CTT). Majority of secondary glaucomas were managed medically. CONCLUSION: In our cohort, PCG was the most common childhood glaucoma and CTT was the most common surgery performed in these eyes. Steroid-induced and traumatic glaucomas were the most common acquired glaucomas; appropriate measures should be taken to avert these preventable glaucomas in children.

ABSTRACT

Aqueous drainage devices play an important role in the treatment of refractory glaucomas; however, they can be associated with early and late postoperative complications, including conjunctival dehiscence, which must be repaired surgically. Recurrent dehiscence despite surgical repair is uncommon and can be sight threatening. We discuss possible causes and management options of recurrent conjunctival dehiscence in a 2-year-old and the role of oral doxycycline and azithromycin in its management.

ABSTRACT

PURPOSE: The purpose of this study was to report the outcomes of Silicone Ahmed Glaucoma Valve (AGV) implantation in the management of refractory pediatric glaucoma. METHODS: Between 2007 and 2015, 76 eyes of 64 children aged 16 years or younger underwent AGV implantation. We included 65 eyes of 53 children with follow up ≥6 months; 24 eyes had primary congenital glaucoma (PCG) and 41 eyes had secondary pediatric glaucoma (SPG). Success was defined as IOP>5 and ≤21 mm Hg with or without topical antiglaucoma medications; considered failure, when repeat glaucoma surgery was need or loss of light perception. Primary outcome measure was success of AGV in refractory pediatric glaucomas and secondary outcome measure was comparison of outcomes in PCG and SPG. RESULTS: The median age at AGV implantation was 3 years (interquartile range, 2, 12), and median follow up was 27 months (15, 39). The overall cumulative success probability was 88% [95% confidence interval (CI), 76%-94%] at 1 year and was maintained up to 4 years. The success probability in PCG was 91% (80.8%-100%), and SPG was 83% (72%-96%) at 1 year and 4 years (P=0.49). Among the preoperative factors, number of previous intraocular surgeries (hazard ratio of 2.24; 95% CI, 1.14-4.37, was significantly associated with failure; P=0.01). Tube-related complications (16%) were similar in both the groups. One eye in each group had sight-threatening complication. CONCLUSIONS: AGV implantation had good success rate in refractory pediatric glaucoma. The success rates were similar in PCG and SPG as were the complications. Number of prior intraocular surgeries was a risk factor for failure.
