RESUMO
PURPOSE: To study intraocular pressure (IOP) outcomes after surgery for rhegmatogenous retinal detachment in Schwartz syndrome. METHODS: We reviewed records of 32 eyes of 32 patients with Schwartz syndrome (patients with rhegmatogenous retinal detachment, IOP above 21 mmHg, and open angles without angle recession, chronic steroid use or other secondary causes of increased IOP) who had undergone surgical treatment consisting of scleral buckling or vitrectomy. Intraocular pressure, number of medication, best-corrected visual acuity were compared at baseline and postsurgery visits and also studied association of various factors on long-term IOP. RESULTS: The median duration of rhegmatogenous retinal detachment was 2 months, and the inter quartile range was 1 to 12 months. Follow-up was 15 months (inter quartile range: 7-33 months). Sixteen (50%) had prior ocular trauma. Baseline IOP was 35 ± 8 mmHg, and 12% (4/32) of patients were on IOP-lowering medication at presentation. At the final visit, mean IOP was 17 ± 6 mmHg and 59% patients (19/32) required additional IOP-lowering medication or surgery for IOP control. CONCLUSION: Surgical management of rhegmatogenous retinal detachment resulted in significant reduction in IOP. At the final visit, 41% did not require any IOP-lowering medication or surgical intervention for IOP control.

OBJECTIVE: To report the profile of newly diagnosed childhood glaucoma using the Childhood Glaucoma Research Network (CGRN) classification, presenting over 1 year from across centers in India. DESIGN: Prospective observational multicentric study. SUBJECTS: Newly diagnosed children aged < 18 years diagnosed with childhood glaucoma according to CGRN criteria presenting between January and December 2019 to 13 centers across India. METHODS: All children underwent a comprehensive ocular examination, including examination under anesthesia for younger children, and were diagnosed with childhood glaucoma as per CGRN. Data were entered in a standard Excel chart. Refraction and visual acuity assessments were done when feasible. MAIN OUTCOME MEASURES: The profile of newly diagnosed childhood glaucoma in different parts of India and the severity of glaucoma at presentation. RESULTS: A total of 1743 eyes of 1155 children fulfilled the definition of glaucoma and were analyzed. Primary congenital glaucoma (PCG) comprised the single largest group (34.4%), most of which were infantile onset (19%). Neonatal-onset PCG comprised 6.2% of all glaucoma. Secondary glaucoma constituted 53.4% of all glaucoma, one-half of which were acquired conditions (28%), followed by isolated ocular anomalies (14.7%), glaucoma after cataract surgery (6.7%), and glaucoma with nonacquired systemic diseases (4.5%). Of the 1743 eyes with glaucoma, all 3 parameters for severity grading were available in 842 eyes, of which 501 (59.5%) eyes presented with mild, 320 (38%) with moderate, and 21 (2.5%) with severe glaucoma. Nearly one-third of the children (28.5%) were not brought back for follow-up after the initial treatment given. CONCLUSIONS: Our study has one of the largest numbers of consecutive children with glaucoma classified according to the CGRN classification. Despite a widely diverse population, the profile of childhood glaucoma was relatively uniform across India. Childhood glaucoma is a significant problem in India, primarily treated in tertiary care hospitals. The data presented may be the tip of the iceberg because we have only reported the children who reached the hospitals offering treatment for this challenging disease.

PURPOSE: The study aimed to assess the effect of hypertension, and use of systemic beta blockers (BB) and other antihypertensives on ocular perfusion by optical coherence tomography angiography (OCTA) in normal, suspect, and glaucomatous eyes. METHODS: Cross-sectional study in tertiary eye care center. Prospectively recruited consenting subjects between 18 and 90 years with or without glaucoma. Measured the optic nerve peripapillary perfusion and flux and macular vessel density (MVD: 6 × 6 and 3 × 3 mm) in the superficial retinal layer using OCTA. RESULTS: Included 200 eyes (112 patients). Compared to nonhypertensives or those on non-BB antihypertensives (NBB), hypertensives on BB had lower peripapillary perfusion (43.45,43.40, 42.05%, P = 0.003), and MVD (6 × 6 mm: 16.65, 16.70,15.75 mm/mm 2 , P = 0.002; 3 × 3 mm: 18.70, 18.50, 18.00 mm/mm 2 , P = 0.025). Those on systemic BB with vasodilatory properties had similar perfusion parameters as nonhypertensives and NBB. Those on systemic BB without vasodilating properties had significantly lower peripapillary perfusion (42.05 vs 43.30%, P = 0.011) and MVD (6 × 6 mm: 15.15 vs 16.60 mm/mm 2 , P < 0.001; 3 × 3 mm: 17.40 vs 18.70 mm/mm 2 , P = 0.005) compared to nonhypertensives. On multivariate analysis, peripapillary perfusion increased with increase in diastolic blood pressure (ß:0.051, p: 0.04) and increasing age was the only factor found to be significantly associated with decreased peripapillary and macular perfusion parameters. CONCLUSION: Systemic BB users have worse ocular perfusion parameters compared to those on other medications or nonhypertensives on univariate analysis but similar perfusion on multivariate analysis. Those on BB with vasodilation have better ocular perfusion parameters. All BB cannot be considered equally detrimental to ocular perfusion. Further well-controlled prospective studies are needed to reassess the effects of BB with or without vasodilation on ocular perfusion.

Purpose: Comparison of the conjunctiva related complication rates and success rates among eyes with Ahmed glaucoma valve (AGV) implantation in which eye bank derived scleral and corneal patch grafts had been used to cover the tube. Methods: Retrospective comparative study. Patients who underwent AGV implantation between January 2000 to December 2016 were included. Demographic, clinical data, intra and post operative data was obtained from electronic medical records. Conjunctiva related complications were divided into two groups: with and without implant exposure. Conjunctiva related complication rates, success rate, risk factors among eyes with corneal and scleral patch graft were compared. Results: Three hundred and twenty three eyes of 316 patients underwent AGV implantation. Scleral patch graft was used in 214 eyes of 210 patients (65.9%) and corneal patch graft was used in 109 eyes of 107 patients (34%). Median follow up was 14 months. There was no significant difference in the conjunctiva related complication rate (7.3 % in corneal patch graft versus 7.0% in scleral patch graft;p=0.5) and conjunctival dehiscence rate (3.7% versus 4.6%, P = 0.7) among the two groups. Success rate was significantly higher in the corneal patch graft group versus the scleral patch graft group (98% versus 72%; p=0.001). Eyes with corneal patch graft had a higher survival rate (P = 0.01). Conclusion: There was no significant difference in the rate of conjunctiva related complications following corneal and scleral patch grafts used to cover the AGV tube. Eyes with corneal patch graft had a higher success rate and survival rate.

Purpose: To determine agreement between diurnal variation testing (DVT) of intraocular pressure (IOP) with Goldmann applanation tonometer (GAT) and iCare HOME (IH) by an optometrist (OP) and home monitoring by participants (PT). Methods: Patients (18-80 years) with glaucoma and suspects were enrolled. IH IOP and GAT were taken by an OP at 2 h intervals from 8 AM to 4 PM on Day 1 and PT between 6 AM and 9 PM, for the next 2 days. IOP, date, and time were viewed via iCare LINK software. Results: In total,: 72.9. (: 51/70) PT trained were able to take reliable readings. One hundred two eyes (51 patients, age 53 ± 16 yrs) were analyzed. Correlation between optometrist (OP) and participants (PT) was strong and positive {IH OP-IH PT- r = 0.90, p-0.0001;IH PT-GAT- r = 0.79, p-0.0001}. Agreement by Bland Altman plots was limited {IH OP-IH PT mean 0.1 mmHg (95% LOA -5.3 to 5.5), IH PT-GAT 2.2 mmHg (-5.7 to 10.1)}. Intraclass correlation coefficient for IH OP-IH PT was 1.18 (95% CI 1.37-1.09). Intradevice {0.95 (95% CI 0.94-0.97)} and interrater repeatability {0.91 (0.79-0.96)} were good. 37% of eyes had a synchronous peak on GAT and IH during the day DVT. Conclusion: Home tonometry by iCare HOME is easy, feasible, but due to limited agreement cannot substitute GAT DVT.

PRCIS: Angle closure disease was present in 59.3% of eyes with long anterior zonules (LAZ). The cause is multifactorial including a thick anteriorly positioned crystalline lens, shorter axial length, and increased lens thickness to axial length factor. PURPOSE: To study the profile of eyes with LAZ presenting in a glaucoma clinic in a tertiary eye care centre and understand the pathogenesis of angle closure disease in these eyes. METHODS: This was a retrospective cross-sectional study.All patients with LAZ seen from January 2014 to December 2018 were included. Demographic and clinical characteristics were noted. LAZ eyes (177 eyes of 177 patients) were compared with an equal number of age and sex-matched controls. LAZ was defined as radially oriented zonular fibers (both pigmented and nonpigmented), extending central to the normal zonular termination zone on the anterior lens surface >1 mm beyond their usual insertion of 1.42±0.24 mm from the lens equator onto the mid peripheral zone or central to it, as seen on slit-lamp examination, following pupillary dilation by a single examiner. Glaucoma was defined according to the International Society for Geographical and Epidemiological Ophthalmology classification. The following biometric parameters were compared: anterior chamber depth (ACD), axial length (AXL), lens thickness (LT), lens position (LP=ACD+0.5×LT), relative lens position (RLP=LP/AXL); lens thickness to axial length factor (LAF=(LT/AXL)×10). LAZ eyes without angle closure disease were also compared with controls. RESULTS: Mean age of patients with LAZ was 64.8±8.1 years. Of these, 63.3% were females. Angle closure disease was present in 59.3% (105/177) patients. Majority of these eyes were primary angle closure suspects (PACS) (53.3%, n=56). Significant differences were found between LAZ eyes and controls for LT (4.8±0.38 mm vs. 4.49±0.40 mm, P<0.0001), ACD (2.68±0.39 mm vs. 3.0±0.32 mm, P<0.0001), AXL (22.37±0.79 mm vs. 22.94±1.1, P<0.0001), LAF (2.14±0.19 vs. 1.96±0.21, P<0.0001), and LP (5.07±0.37 vs. 5.3±0.25, P<0.0001). CONCLUSIONS: Angle closure was present in more than half the eyes with LAZ. Majority of these eyes were PACS or had primary angle closure. LAZ eyes had a thicker lens, shallow AC, a shorter axial length and an increased LAF as compared with age and sex matched normal controls. The presence of LAZ may be an indicator of increased risk for angle closure.

Purpose: To evaluate the incidence of shallow anterior chamber in the early postoperative period following Ahmed glaucoma valve (AGV) implantation and its effect on the hypertensive phase (HP), intermediate-term intraocular pressure (IOP) control, and success rate. Methods: A retrospective analysis of 369 eyes of 360 patients who underwent AGV implantation between January 2005 and January 2020 with a minimum follow-up of 2 months was performed. Twenty-six patients developed shallow anterior chamber (AC) within 8 weeks following surgery (cases). They were compared with 39 randomly selected controls (no shallow AC post AGV). HP (IOP spike >21 mmHg), use of ocular hypotensive medications, and other associations were compared. Results: Incidence of shallow AC post AGV was 7% (95% confidence interval [CI] 4, 9). The onset of shallow AC was 3 ± 2.1 days and resolved within 6 ± 4.7 days. Hypotony (12 [47%] vs. 1 [2.5%], P 0.0001) and choroidal detachment (CD; 7 [27%] vs. 3 [8%], P 0.03) were more common in cases compared to controls. The HP occurred in 11 (43%) cases versus 13 (34%) controls (P 0.4). Cases required more ocular hypotensive medications than controls at the end of 8 weeks (1.1 ± 1 vs. 0.5 ± 0.5, P 0.01). There was no significant difference in the qualified success between the groups at 1 year. Conclusion: The development of postoperative shallow AC post AGV implantation was not detrimental to IOP control at 1 year. However, there is a need to monitor the occurrence of HP in these eyes.

Purpose: Idiopathic elevated episcleral venous pressure (IEEVP) is a rare cause of secondary glaucoma and is a diagnosis of exclusion. The aim of this study was to describe the clinical presentation and analyze the outcomes of medical and surgical management in eyes diagnosed with idiopathic elevated episcleral venous pressure. Methods: A retrospective analysis of eyes diagnosed with IEEVP over a 5-year period between April 2012 and March 2016 was performed. The demographic details, medical history, and clinical course of the cases were obtained from the medical records. Data pertaining to the severity of glaucomatous damage, response to medical management, need for surgical intervention, and their outcomes were analyzed. Results: Fifteen eyes of 13 patients were included. Thirteen eyes (86.6%) had open angle configuration. Among the 13 eyes that had glaucoma, eight eyes (61.5%) had severe glaucoma, four eyes (30.7%) had moderate glaucoma, and one eye (7.6%) had mild glaucoma. The median follow-up was 210 days. Seven of the 15 eyes (46.6%) required a glaucoma filtration procedure, and three underwent prophylactic sclerotomies. 71.4% of these eyes had complete success. One out of the seven operated eyes required choroidal drainage post-operatively. Conclusion: IEEVP is an extremely rare condition and presents with raised intra-ocular pressure and tortuous episcleral vessels. The management of IEEVP is similar to that of primary open angle glaucoma. Uveal effusion is to be anticipated, and hence, combining trabeculectomy with prophylactic sclerotomies is advisable.

Purpose: To compare outcomes of surgical management of uveitic glaucoma (UG) and steroid-induced glaucoma (SIG) in children in terms of intraocular pressure (IOP) control, visual acuity, and associations for failure. Methods: This was a retrospective case-control study of consecutive UG (cases) and non-uveitic SIG (controls) in children <18 years of age who underwent surgery between January 2005 and December 2017. Results: Primary trabeculectomy with mitomycin C (MMC) was performed in 12 cases (mean age: 9.2 ± 4.3 years) and 40 controls (mean age: 10.4 ± 3.7 years) (P = 0.33). Primary phaco-trabeculectomy with MMC was performed in 11 cases (mean age: 11.4 ± 4.7 years) and 16 controls (mean age: 10.4 ± 3.4 years) (P = 0.57). IOP control (P = 0.26), visual acuity (P = 0.97), number of glaucoma medications (P = 0.06), and survival rates (49% cases vs. 68% controls at 5 years; P = 0.22) were similar between the two groups following trabeculectomy. Survival rates in the phaco-trabeculectomy group at 5 years were 68% cases vs. 69% controls (P = 0.71). IOP was higher (P = 0.008) and visual acuity was worse (P = 0.02) in cases at the last visit. Associations for failure (univariate analysis) were younger age (OR: 6.29, 95% CL: 1.43, 27.67; P = 0.03) and male gender (OR: 4.79, 95% CL: 1.09, 20.97; P = 0.04). On multivariate analysis, younger age (OR: 11.985, 95% CL: 1.071, 134.153; P = 0.04) remained significant. Preoperative number of uveitic attacks was protective on univariate (OR: 0.75, 95% CL: 0.48, 1.15; P = 0.1) and multivariate analyses (OR: 0.49, 95% CL: 0.24, 0.09; P = 0.04). Conclusion: Outcomes of trabeculectomy between cases and controls were similar in our series. However, phaco-trabeculectomy in pediatric uveitic eye group fared worse than eyes with SIG.

Purpose: To determine correlation and agreement between intraocular pressure (IOP) peak and fluctuations detected by day diurnal variation (day DVT) to that after the water-drinking test (WDT). Methods: Patients (18-80 years) with glaucoma, suspects, and ocular hypertension (OHT) were enrolled. IOP readings were taken on applanation tonometer, at 2-h intervals, from 8 AM to 3 PM (DVT). 3 PM IOP served as WDT baseline. Patients consumed water (10 mL/kg) in 5-15 min, at 3 PM, after they fluid fasted for 2 h. IOP was recorded every 15 min, from 3.30 to 4.30 PM. Results: A total of 200 eyes (100 patients) were included. 58.5% were established glaucoma, 32% suspects, 9.5% OHT. Correlation between mean and peak IOP by WDT and day DVT was strong and significant (r = 0.89, P < 0.00; r = 0.73, P < 0.00) while it was weak for fluctuation (r = 0.12, P < 0.07). Agreement on Bland and Altman plots was limited for mean IOP and poor for peak and fluctuations. Conclusion: An exaggerated WDT response may indicate a compromised outflow facility and warrant close patient monitoring but the WDT cannot substitute day DVT in our clinical practice.

PURPOSE: The aim of this study was to report the incidence of presumed steroid response in contralateral eye of patients who underwent glaucoma filtration surgery. METHODS: We reviewed records of 298 glaucoma patients (147 PACG [primary angle-closure glaucoma], 129 POAG [primary open-angle glaucoma], and 22 JOAG [juvenile open-angle glaucoma]) who underwent either trabeculectomy alone or trabeculectomy with cataract extraction. All patients received prednisolone acetate 1% eye drop postoperatively in the operated eye for up to 6 to 8 weeks. The contralateral eye received the same antiglaucoma medications as before. Information collected included age, sex, number of antiglaucoma medications in the fellow eye preoperatively, and VFI (visual field index). The preoperative intraocular pressure (IOP) in the contralateral eye was taken as the baseline. The maximum IOP recorded postoperatively up to a follow-up period of 6 to 8 weeks was noted. A steroid response was defined as rise in the IOP by ≥6 mmHg. RESULTS: In this study, 298 eyes of 298 glaucoma patients were included. The mean age of patients was 60.1 ± 13.7 years. The mean number of antiglaucoma medications in the fellow eye pre-operatively was 2.4 ± 1.2. Mean preoperative and postoperative IOP in the fellow eye were 17.46 ± 7 and 19.37 ± 7.1 mmHg, respectively. Sixty-three eyes out of 298 eyes (21.14%) showed a rise in IOP by 6 mmHg. The maximum IOP difference noted was 15 mmHg. The average time interval to the defined steroid response was 16.13 days. The majority showed a steroid response within 19 days. CONCLUSION: Steroid response is a significant factor leading to elevated IOP postoperatively in the contralateral eye as well.

Purpose: The aim of this study was to compare SD-OCT parameters between disc suspects and "pre-perimetric" glaucomatous discs classified on disc photos. Methods: Disc photos of suspicious discs with normal Humphrey visual fields (HVF) were graded as normal or pre-perimetric glaucomatous based on the consensus of three masked glaucoma specialists. RNFL and GCL-IPL maps of SD-OCT (Cirrus OCT) of these eyes were studied. Quantitative RNFL parameters were compared. Both groups were also compared with respect to parameters being classified as abnormal (at the 1% level), and the pattern of GCL-IPL and NFL maps were assessed qualitatively and classified as normal or pre-perimetric glaucomatous by a masked glaucoma specialist. Results: The average and inferior RNFL thicknesses were decreased in pre-perimetric glaucomatous eyes compared to normal eyes (p 0.01) The average, minimal, inferotemporal and inferior sector GCL-IPL thicknesses were decreased in pre-perimetric glaucomatous eyes (all P < 0.002) The highest AUC was for the inferior RNFL thickness (0.771) followed by average RNFL thickness (0.757) The sensitivity and specificity for any one abnormal RNFL parameter was 71.9% and 59.7%, for GCL-IPL parameters was 70% and 69.1% The positive (PLR) and negative likelihood ratios (NLR) were 1.78 and 0.47 for RNFL and 2.26 and 0.43 for GCL-IPL parameters. For the qualitative assessment of RNFL and GCL-IPL maps, the sensitivity, specificity, PLR and NLR were 75%, 77.2%, 3.29, and 0.32, respectively. Conclusion: Pre-perimetric disc suspects had greater OCT changes compared to normal disc suspects. Qualitative assessment of RNFL and GCL-IPL maps had the highest discriminatory ability.

AIMS: To assess the incidence, risk factors and outcomes of management of delayed suprachoroidal haemorrhage (DSCH) in children who had undergone Ahmed glaucoma valve implantation. METHODS: A retrospective case-control study of eyes which developed DSCH in children <18 years of age who underwent surgery between January 2009 and December 2017 with a follow-up of at least 2 months was performed. Nine cases were compared with 27 age, gender and surgeon matched controls who had undergone surgery during this period. RESULTS: The incidence of DSCH was 4.7% (95% CL 1.5% to 7.7%, 9 eyes of 191 children). There were no significant differences between cases and controls in baseline details except for the number of intraocular pressure (IOP) lowering medications (p=0.01) and follow-up period (p=0.001). Risk factors identified on univariate analysis (p≤0.1) were axial length (p=0.02), diagnosis of primary congenital glaucoma (p=0.05), postoperative hypotony (p=0.07) and aphakia (p=0.1). None of them were found to be significant on multivariate analysis. Five eyes, three with retinal apposition and two with retinal detachment, underwent surgical drainage. There were no significant differences in the outcomes of eyes which underwent drainage compared with those which did not. Failures, defined as IOP>18 mm Hg despite use of medications, loss of light perception, phthisis or removal of the implant were more frequent in cases (three eyes, 33.3%) compared with controls (four eyes, 14.8%) (p=0.002). CONCLUSIONS: None of the risk factors analysed in our series proved to be significant. Failures were more common in eyes with choroidal haemorrhage, despite surgical intervention.

PURPOSE: To study the safety of phacoemulsification in eyes with long anterior zonules (LAZs). SETTING: Institute. DESIGN: Retrospective interventional case series. METHODS: All patients with clinically proven LAZs who had undergone phacoemulsification by a single surgeon from January 2014 to December 2018 were included. All cases of LAZs with cataract extraction by procedures other than phacoemulsification or combined with any other ocular surgery were excluded. Sixty-five eyes of 52 patients were analyzed. Phacoemulsification with capsulorhexis that involves sacrificing the LAZs was performed. The primary outcome measures were the incidence of capsulorhexis extension or the need to rescue intraoperatively and the rate of intraoperative complications. Secondary outcomes assessed were the percentage of eyes within ±0.5 diopters (D) and ±1 D of the target refraction. RESULTS: Sixty-five eyes (52 patients) were analyzed; the mean age of patients was 67.3 ± 7.4 years. The successful completion of an adequately sized capsulorhexis without extension or rescue was seen in 100% of cases. The incidence of intraoperative complications was 1.5% (posterior capsular rupture in 1 eye). The mean postoperative corrected distance visual acuity was 0.05 ± 0.1 (logarithm of the minimum angle of resolution) at a mean of 26.8 ± 7.6 days. The mean spherical equivalent was -0.15 ± 0.7 D. Eyes within ±0.5 D and ±1.00 D of the target refraction were 77% and 94%, respectively. CONCLUSIONS: Phacoemulsification in eyes with LAZs can be safely performed through an adequately sized capsulorhexis by sacrificing, ie, cutting or breaking, the anteriorly inserted zonules 360 degrees without significant intraoperative complications.

PRECIS: Phacotrabeculectomy with adjunctive mitomycin C is a good option for the management of coexisting cataract and glaucoma. Strict preoperative control of inflammation and close follow-up are essential in the management of eyes with uveitic glaucoma (UG). PURPOSE: The purpose of this study was to compare the outcomes of phacotrabeculectomy with adjunctive antimetabolites in the management of patients with UG and patients with primary open-angle glaucoma (POAG). MATERIALS AND METHODS: A retrospective case-control study of 112 patients with UG and 120 patients with POAG who underwent phacotrabeculectomy with mitomycin C and had a follow-up of ≥12 months between January 2000 and June 2015 was performed. Patients who had undergone intraocular surgery or cyclodestructive procedures earlier were excluded. The primary outcome was intraocular pressure (IOP) control; secondary outcomes included visual acuity and complication rates. RESULTS: IOP control was similar at the final visit in the UG group (14.52±6.74 mm Hg) and the POAG group (14.39±4.18 mm Hg) (P=0.867). Kaplan-Meier survival analysis showed a cumulative probability of survival (IOP: 6 to 18 with or without medications) in 71% and 77% at the end of 5 years (P=0.094) in the UG and POAG groups, respectively. Visual outcomes were worse in the UG group (0.5±0.68 logMAR units), as compared with the POAG group (0.27±0.47 logMAR units) (P=0.002). Complications such as cystoid macular edema (P=0.025) and posterior capsular opacification (P=0.004) were more common in the UG group. Recurrence of inflammation occurred in 34 eyes (30.04%) in the UG group. CONCLUSION: Meticulous control of perioperative and postoperative inflammation could have contributed to the favorable long-term outcomes of phacotrabeculectomy in UG, as compared with POAG.

PURPOSE: A prospective longitudinal cohort study was performed to assess the incidence of and risk factors for the development of glaucoma following surgery for congenital/infantile cataract. METHODS: One hundred and one eyes of one hundred and one children, ≤12 years of age who had follow-up of ≥24 months were included. Group I included those who underwent surgery using an anterior approach, group II included those who underwent surgery using a posterior approach, and group III included those who underwent surgery using an anterior approach along with foldable intraocular lens implantation. Standard definitions for glaucoma and glaucoma suspect were used. The Cox proportional hazard model was used to analyze risk factors for glaucoma. RESULTS: Group I: 30 eyes (29.7%); group II: 11 eyes (10.9%); group III 60 eyes (59.4%). The incidence of glaucoma + glaucoma suspect was 7.9% (95% CL: 2.6, 13.2%) in the entire group. The incidence in group I was 16.7% (95% CL 3%, 30%), in group II was 18.2% (95% CL: 0, 41%) and in group III was 1.7% (95% CL: 0, 4.9%). Gonioscopy revealed high iris insertion with grade I (modified Shaffer grading) in one eye each in the glaucoma and glaucoma suspect group and open angles in the rest. Age at surgery of ≤3 months (HR: 6.6, 95% CL: 1.4, 30.6, p = 0.01) was found to be a significant risk factor within the aphakic group. CONCLUSIONS: Younger age at the time of surgery was the only identifiable risk factor for glaucoma.

PRECIS: Secondary ocular hypertension (OHT) is common in carotid-cavernous fistulas (CCFs). Management of elevated intraocular pressure (IOP) is possible with a multidisciplinary approach. The ipsilateral normal eyes may have higher IOP than the contralateral eyes. PURPOSE: To study the IOP profile of the eyes of patients with a CCF, treatment outcomes for elevated IOP, and intereye IOP asymmetry in the eyes with normal IOP. METHODS: This was a retrospective case series. A total of 64 eyes of 60 patients with digital subtraction angiography-proven CCF diagnosed from the year 2000 to 2016 were included. The demographics, clinical features, management, and outcomes were recorded. The primary outcome included understanding of the cause of elevated IOP. The secondary outcomes included comparison of the IOP between contralateral eyes and ipsilateral normal eyes (IOP <21 mm Hg) and management outcomes for elevated IOP. RESULTS: The mean age of the patients was 45.6±18.2 years. In the study population, 70% of the patients were males. Indirect CCF was present in 55% of the eyes. It was found that 64.06% (n=41) of the eyes had elevated IOP, glaucoma, or were glaucoma suspects. Among all the eyes, 40.62% (n=26) of the eyes had secondary OHT due to elevated episcleral venous pressure, whereas 7.81% (n=5) of the eyes had secondary open-angle glaucoma. The mean IOP was higher in the ipsilateral eyes than in the other eyes (22.95±7.1vs. 15.11±2.99 mm Hg; P<0.001). The mean IOP in the ipsilateral normal eyes was higher than that in the contralateral eyes, with a mean difference of 2.92±2.29 mm Hg (confidence interval of the mean difference: 1.90-3.94 mm Hg; P<0.0001). IOP reduction (<21 mm Hg) was achieved in 70.7% of the patients following CCF management with intermittent carotid massage, endovascular treatment, IOP-lowering medications, or a combination among these. CONCLUSIONS: Secondary OHT due to elevated episcleral venous pressure was more common than secondary open-angle glaucoma. Ipsilateral normal eyes had higher IOP than contralateral eyes. IOP-lowering agents and management of CCF resulted in IOP control in most patients.

PURPOSE: To evaluate the outcome of rhegmatogenous retinal detachment (RRD) surgery in eyes with preplaced glaucoma drainage device (GDD) with respect to intraocular pressure (IOP) control as well as success of retinal detachment (RD) surgery. METHODS: It is a retrospective case series. The case records of patients who underwent RD surgery after GDD implantation from 2000 to 2014 were screened. The demographic data, ocular examination findings at all visits, details pertaining to retinal detachment and its repair, and the postoperative course was documented. RESULTS: Twelve patients were included in study. The mean age of patients was 24.3 years (median 11 years; range 3-72 years). Male: Female ratio was 3:1. Mean duration between GDD and RD was 24 months (4 days-91 months). Of the ten eyes that underwent surgery, nine eyes underwent pars plana vitrectomy, and in one eye scleral buckling was done. GDD was removed only in one eye. At final follow-up, retina was attached with controlled IOP in 6 (60%) eyes, of which 5 (50%) had improvement in best corrected visual acuity. CONCLUSION: Pars plana vitrectomy was required in almost all cases for the management of RD in eyes with preplaced GDD. Retinal reattachment with good IOP control could be achieved in 60% of eyes. Removal of the drainage device was not essential for the effective management of the RRD in most cases. With multidisciplinary approach, close follow-up and timely intervention, vision can be preserved along with glaucoma control and successful retinal reattachment.

PURPOSE: To assess the prevalence, incidence, and risk factors for the development of glaucoma in patients with aniridia. METHODS: Retrospective analysis of case records of patients diagnosed as having congenital aniridia between January 1986 and December 2011 was performed. Patients with a follow-up of more than 12 months were included. RESULTS: Ninety-one patients (180 eyes) with the diagnosis of aniridia were identified from the case records. Two eyes were excluded from the final analysis; one had developed phthisis and the other had been enucleated. Seventy-four patients (81.3%) were younger than 18 years at initial presentation. The prevalence of glaucoma at presentation was 28.8%, which could be further categorized as ocular hypertension in 19 eyes (10.5%) and glaucoma in 33 eyes (18.3%). Thirty-one eyes (28.4%) developed elevated intraocular pressure (IOP) during the follow-up period: ocular hypertension in 23 eyes (17.9%) and glaucoma in 8 eyes (6.25%). The mean IOP at the time of diagnosis was 33.9 ± 8.6 mm Hg (range: 24 to 60 mm Hg). The mean duration of follow-up was 8.1 ± 5.7 years (range: 1 to 28 years). The cumulative probability of developing elevated IOP was 4% at the end of 8 years of follow-up; this increased to 88% at the end of 28 years of follow-up. Univariate logistic regression analysis identified higher baseline IOP (odds ratio [OR]: 1.2; 95% confidence interval [CI]: 1.2 to 1.4) and limbal stem cell deficiency (OR: 2.8; 95% CI: 1.4 to 5.6) as significant risk factors for the development of elevated IOP. Higher baseline IOP remained significant on multivariate analysis (OR: 1.2; 95% CI: 1.2 to 1.4). CONCLUSIONS: Glaucoma occurs in a substantial proportion of patients with aniridia. Eyes with increased IOP at baseline are at a higher risk. [J Pediatr Ophthalmol Strabismus. 2017;54(4):250-255.].

AIM: To evaluate the short-term outcomes of lensectomy, combined with vitrectomy, scleral-fixated intraocular lens (SFIOL), and trabeculectomy with adjunctive mitomycin C (MMC) in patients with subluxated/dislocated crystalline lenses with associated elevated intraocular pressure (IOP). MATERIALS AND METHODS: This retrospective case series included 51 eyes of 51 patients who underwent lensectomy, vitrectomy, and SFIOL combined with trabeculectomy with MMC between 2003 and 2012. The main outcome measures assessed were IOP, change in visual acuity, IOP-lowering medications, and the complications and reoperation rates. RESULTS: The most common etiology observed was blunt trauma in 35 eyes (68.6%). Glaucomatous optic neuropathy was detected in 13 eyes (25.49%) preoperatively. The IOP reduced significantly from a preoperative mean of 26.3±11.5 mm Hg to 13±4.6 mm Hg (P<0.001) at the final visit. The mean preoperative number of IOP-lowering medications of 2.9±0.8 reduced to 0.3±0.7 at last follow-up (P<0.001). The best-corrected visual acuity (Snellens) improved significantly from 20/600 to 20/60 (P<0.001). Complete success defined as IOP≤21 mm Hg without medications was achieved in 93%±5% and 80%±13% at 1 and 2 years, respectively. Major postoperative complications included retinal detachment in one eye and SFIOL dislocation in another. CONCLUSIONS: The technique of combining SFIOLs with trabeculectomy with adjunctive MMC in the management of subluxated/dislocated lenses resulted in good IOP control and improvement in visual acuity.
