Purpose: To compare the intraocular pressure (IOP) profile and the incidence of IOP spikes following selective laser trabeculoplasty (SLT) between pigmentary glaucoma (PG) and primary open-angle glaucoma (POAG)., Materials and Methods: Retrospective comparative study of 65 PG eyes of 51 patients matched with 65 POAG eyes of 65 patients who received SLT. Matching was done based on age, gender, glaucoma severity, pre-laser IOP, and number of medications. Post-SLT IOP spike was defined as IOP elevation ≥5mmHg, 30-45 min after the laser., Results: In PG and POAG groups, the average age was 62.33 ± 9.18 and 62.58 ± 9.19 years (p = 0.95). The glaucoma severity (p = 0.708), baseline IOP (PG = 21.61 ± 1.34mmHg vs. POAG = 21.13 ± 5.09mmHg, p = 0.943), and number of topical glaucoma medications(PG = 2.34 ± 1.34 vs. POAG = 2.1 ± 1.41, p = 0.342) were comparable. More PG patients were on oral acetazolamide (PG = 26.15% vs. POAG = 1.5%, p < 0.001). Average logMAR visual acuity was significantly higher in the POAG group (0.207 ± 0.3 vs. 0.192 ± 0.37, p = 0.012). Eyes with PG received lower laser energy (POAG = 63.65 ± 22.03 mJ vs. PG = 43.71 ± 25.68 mJ, p < 0.001). IOP spikes were recorded in 5 PG eyes (7.6%) and none in the POAG group (p = 0.058). Failure rates were similar (PG = 50.7% and POAG = 43.1%, p = 0.205). In multivariable analysis, only pre-laser IOP (coefficient = 2.154 [CI: 0.765-3.543], p = 0.003) was a significant predictor of IOP change percentage after 12 months., Conclusions: SLT was comparably effective in both PG and POAG. IOP spikes were observed only in the PG group, though the total laser energy was lower in this group compared with POAG., Competing Interests: Declaration of conflicting interestsThe author(s) declare they have no relevant financial disclosure.

Purpose: Attempts at engaging relatives of glaucoma patients in education and screening have had limited success. This study explores the feasibility of an electronic intervention to facilitate direct yet reliable glaucoma risk communication between open-angle glaucoma patients (probands) and their first-degree relatives (FDRs)., Design: Prospective survey and assessment of intervention., Participants: Fifty adult probands, engaging 140 FDRs., Methods: Phase I was an iterative process involving creating a customized website and Quick Response (QR)-code-based intervention designed with input from probands, FDRs of patients, community members, and researchers. In phase II, the intervention was deployed in a clinical setting; this involved recruiting probands who had a smartphone and were willing to use the QR-code to message their FDRs a standard message, including a website link about glaucoma risk in FDRs and the importance of getting examined. Follow-up interviews were conducted with probands 1 to 2 weeks after their clinic visit to assess the impact of the intervention. Demographic data, website analytics, and participant feedback were collected and analyzed., Main Outcome Measures: Increased awareness of glaucoma risk among FDRs and enhanced discussions., Results: At the time of the first interview, probands reported that 70% of the FDRs were aware of the probands' glaucoma diagnosis, but only 26% had undergone glaucoma screening. Ninety percent of probands had no issues using the QR-codes. Website analytics recorded 73 visits from 51 distinct internet protocol addresses (IPs). After receiving the standard message, 95% of FDRs followed up with the probands, actively discussing glaucoma. Of the probands, 84% completed the follow-up interview 1 to 2 weeks after enrollment. Fifty-nine percent of the FDRs were reported to have scheduled screening appointments. The collected feedback revealed that 96% of probands found the intervention helpful, fostering glaucoma discussions with their FDRs and improving probands' comfort level in discussing health issues with FDRs from baseline (very comfortable: 88%, comfortable: 8%, neutral: 2%, and very uncomfortable: 2%) to the follow-up interview (very comfortable: 98% and comfortable: 2%)., Conclusions: This innovative online method of communicating the risk of glaucoma to FDRs of probands prompted and increased the comfort level of familial discussions of glaucoma. More than half of FDRs reported making an appointment to get screened for glaucoma., Financial Disclosure(s): Proprietary or commercial disclosure may be found in the Footnotes and Disclosures at the end of this article., (Copyright © 2023 American Academy of Ophthalmology.

Prcis: In this retrospective study, the use of chronic antithrombotic therapy (ATT) did not increase the risk of hemorrhagic complications after trabecular bypass microstent surgery and phacoemulsification. Stent type and female sex were associated with hyphema., Purpose: To report the incidence of hemorrhagic complications after trabecular bypass microstent surgery and phacoemulsification with and without (ATT)., Methods: Retrospective case series on glaucoma patients on chronic ATT who underwent trabecular bypass microstent surgery (iStent, iStent inject, and Hydrus) combined with phacoemulsification between 2013 and 2019 with ≥3-month follow-up. The primary outcome measure was the incidence of hemorrhagic complications within a 3-month postoperative period. Generalized estimating equations were created to account for inter-eye correlation and logistic regression analysis was performed to identify factors predictive of hemorrhagic complications., Results: Of 333 patients (435 eyes), 161 patients (211 eyes) were on ATT and 172 patients (224 eyes) were not on ATT; both groups were similar in age and baseline ocular characteristics. The only hemorrhagic complication was hyphema, which occurred in 84 (19.3%) eyes (41 ATT, 43 non-ATT eyes; P = 1.00). Onset was at postoperative day 1 in 98.8% of eyes, with a duration of 1 week in 73.8% of eyes, without difference between ATT and non-ATT groups. Hyphema was most common with Hydrus microstent (36.4%) versus iStent (19.9%) and iStent inject (8.5%) ( P = 0.003). In the multivariate model, the female sex was a predictor of hyphema [hazard ratio (HR) = 2.062; P = 0.009], iStent inject was protective against hyphema (HR = 0.379; P = 0.033), whereas Hydrus did not reach statistical significance (HR = 2.007; P = 0.081). Age, systemic comorbidities, ATT use, and baseline ocular characteristics were not significant predictors., Conclusions: Hemorrhagic complications after trabecular bypass microstent surgery were limited to transient hyphema and were not associated with chronic ATT use. Stent type and female sex were associated with hyphema., Competing Interests: Disclosure: DL: Consultant: Allergan, Inc. Research: Allergan, Inc. Speaker: Glaukos Corp.

Purpose: To assess real-world effectiveness and tolerability of fixed-dose combination netarsudil 0.02%/latanoprost 0.005% (FCNL) in management of glaucoma patients in a tertiary eye care center., Methods: This retrospective cohort study included glaucoma patients initiated on FCNL from January 2018 to July 2021 with at least 1-month follow-up. Demographic and clinical data were collected at baseline and at follow-up visits through 12 months. Patient-solicited side effects were recorded at each visit. Maximum glaucoma pharmacotherapy was defined as surgery/laser being the next treatment option following an intensive pharmacotherapy regimen, or when pharmacotherapy could not be increased due to allergy/intolerance or all pharmacologic mechanisms already being in use., Results: Seventy-nine eyes of 47 patients were included. Mean age was 67.7 ± 14.7 years. Baseline IOP was 18.7 ± 4.9 mmHg; mean change in IOP (∆IOP) each study visit compared to baseline ranged from - 1.6 ± 3.5 to - 4.4 ± 4.1 mmHg (all p < 0.05). The eyes on maximum glaucoma pharmacotherapy (73.4%) had similar ∆IOP compared to those on non-maximal therapy at each visit (p > 0.2 for all). Forty-three (54.4%) eyes were switched from a prostaglandin analog alone, producing a 1-month IOP reduction of - 4.7 ± 3.9 mmHg at 1 month which remained significant at each visit for the 12-month study period (all p < 0.05). Across all study visits, conjunctival hyperemia was documented in 26 (32.9%) eyes. Subjective blurry vision was reported in 22 (27.8%) eyes without significant worsening of visual acuity at any visit (all p > 0.05). Six (7.6%) and 7 (8.9%) eyes required further medical or surgical/laser intervention, respectively. Kaplan-Meier analysis revealed no significant difference in the need for subsequent medical or surgical intervention between those on maximum and non-maximal pharmacotherapy (p > 0.4)., Conclusion: FCNL was well-tolerated and demonstrated a significant and sustained reduction in IOP, even as last-line therapy before incisional or laser surgery in those on maximum glaucoma pharmacotherapy. FCNL is a viable treatment option for glaucomatous eyes before consideration of surgical intervention., (© 2022.

Purpose: To evaluate the efficacy and safety profile of netarsudil 0.02% ophthalmic solution in a tertiary glaucoma referral center., Methods: This retrospective cohort study included patients with glaucoma initiated on netarsudil 0.02% at a single institution from November 2017 to September 2018. Demographic and clinical data were collected, including intraocular pressure (IOP) and drug side effects at baseline and 1-, 3-, and 6-month follow-up visits., Results: A total of 340 eyes of 233 patients were included; mean ± SD patient age was 69.1 ± 12.5 years. One hundred twenty (48%) eyes experienced ≥ 20% decreases in IOP at the 1-month study visit; this effect was maintained through the 6-month visit. IOP-lowering effects in patients using ≥ 3 topical glaucoma medications were similar (all p > 0.1). Eighteen (7.4%) and 7 (2.9%) patients experienced increases in IOP of ≥ 3 and ≥ 5 mmHg, respectively. Across all study visits, conjunctival hyperemia was noted at a rate of 27.6%, and though frequently reported, complaints of blurred vision (31.1%) did not manifest in significant worsening of visual acuity. The rate of drug discontinuation due to insufficient IOP-lowering and side effects was 15.6% and 24.8%, respectively. Twenty-nine (11.4%) and 82 (32.3%) eyes required additional medical and surgical/laser intervention, respectively., Conclusion: Commonly used as the last-line medical therapy in this case series, netarsudil safely and significantly reduced IOP in patients with glaucoma, even in those using ≥ 3 glaucoma medications. Increases in IOP of ≥ 3 mmHg occurred in a small number of patients. Subjective vision changes and conjunctival hyperemia were the most frequently reported side effects., (© 2021.

Purpose: To compare the outcomes of iStent vs. iStent inject implantation combined with phacoemulsification., Methods: This single center retrospective comparative case series included subjects with open angle glaucoma who underwent iStent or iStent inject implantation combined with phacoemulsification with ≥1 year follow-up. The main outcome measures were in-group and between-group changes in intraocular pressure (IOP) and medication number, proportion of eyes that achieved IOP ≤15 mmHg, and surgical success defined as 20% IOP reduction from baseline at 6/12 months. Univariate/multivariate regression analyses were done to identify predictors of surgical failure., Results: One hundred ninety-seven eyes of 148 patients were included (122 iStent, 75 iStent inject). Both groups achieved significant IOP and medication reduction at months 6/12 (P < 0.05). At month 6, IOP was significantly lower in iStent inject vs. iStent eyes (P = 0.003), but the difference was insignificant by month 12 (P = 0.172). Medication number was comparable in both groups at months 6/12 (P > 0.05). More iStent inject eyes achieved IOP ≤15 mmHg at month 6 (P = 0.003) and 12 (P = 0.047). Surgical success was comparable in both groups at months 6/12 (P > 0.05). Kaplan-Meier survival analysis showed similar cumulative rate of surgical failure at year-1 in both groups (P = 0.644). The multivariate model identified older age (P = 0.017) and lower baseline IOP (P = 0.002) as the strongest predictors of surgical failure., Conclusion: Compared to iStent, iStent inject achieved lower IOP at month 6 and higher proportion of eyes achieved IOP ≤15 mmHg at month 6/12. However, surgical success was similar in both groups. Predictors of surgical failure were older age and lower baseline IOP rather than the stent type., Competing Interests: None

Objective: To describe reoperations that occurred within 90 days of minimally invasive glaucoma surgery (MIGS) at a single institution over a 30-month period., Setting: Tertiary care hospital., Design: Retrospective case series., Methods: Charts of adult patients who underwent trabecular microbypass stents, gel microstents, and goniotomy procedures (including gonioscopy-assisted transluminal trabeculotomy) from October 1, 2017, to March 15, 2020, at Wills Eye Hospital were examined. Outcome measures were unanticipated reoperations within the first 90 days after MIGS procedures and the complications that led to these reoperations., Results: A total of 448 MIGS procedures were performed on 436 eyes of 348 patients over a 30-month period by 6 glaucoma surgeons. Of these, 206 (46.0%) were trabecular microbypass stents (198 iStent/iStent inject and 8 Hydrus), 152 (33.9%) were gel microstents, and 90 (20.1%) were goniotomy procedures. Combined phacoemulsification took place in 256 eyes (58.7%). Reoperation within 90 days took place in 23 (5.3%) of 436 eyes, including 16 (10.5%) of 152 eyes in the gel microstent group, 4 (2.0%) of 198 eyes in iStent/iStent inject group, and 3 (3.3%) of 90 eyes in the goniotomy group. Indications for reoperation were elevated intraocular pressure (IOP) in 16 (69.6%) of 23 eyes, gel microstent tip exposure with wound leakage in 3 (13.0%) of 23 eyes, and early gel microstent encapsulation without elevated IOP in 1 (4.3%) of 23 eyes. Two (8.7%) of 23 eyes required reoperation for intraocular lens complications, whereas 1 (4.3%) of 23 eyes had elevated IOP and aphakia requiring reoperation., Conclusions: The rate of reoperation within the first 90 days after MIGS was low. Elevated IOP and complications associated with gel microstents were the main indications for reoperation., (Copyright © 2021 Published by Wolters Kluwer on behalf of ASCRS and ESCRS.)

PRéCIS:: This case series reports safe, effective implantation of XEN gel stents to treat iridocorneal endothelial (ICE) syndrome. The stents continue to function well and have not been occluded by membranes or peripheral anterior synechiae, but continued follow-up is necessary., Purpose: ICE syndrome-related glaucoma is often refractory to medical treatment, and traditional surgical treatment has lower success rates than typical for other types of glaucoma. We present a series of patients who were treated with XEN gel stent implantation., Patients and Methods: Retrospective case series of 4 patients with ICE syndrome who underwent XEN with subconjunctival mitomycin C injection., Results: Average preoperative intraocular pressure was 28.5 mm Hg on 3.8 glaucoma medications, and average postoperative intraocular pressure was 10.5 mm Hg on 1.0 medication. No patients required return to the operating room for additional procedures over an average of 6.9 months of follow-up. One patient had shallow anterior chamber that resolved with conservative management. Another had shallow anterior chamber that resolved with anterior chamber reformation with viscoelastic and developed nonappositional choroidal effusions that had resolved at most recent follow-up of 7 months after surgery. No XEN implants have been occluded by membrane formation or peripheral anterior synechiae., Conclusions: XEN is a safe and effective option for surgical management of ICE syndrome-related glaucoma. Further follow-up surveillance is necessary.
