Purpose
This study aims to assess the risk of glaucoma-related adverse events (GRAEs) in pediatric patients following silicone oil use in vitreoretinal (VR) surgery, positing that silicone oil exposure increases GRAE risk.
Design
A single-center retrospective cohort study at a tertiary care facility.
Participants
Pediatric patients aged 0 to 18 years who underwent VR surgery between April 2019 and April 2021 were included. Patients with previously diagnosed glaucoma or who had undergone glaucoma surgery were excluded.
Methods
Review of medical records for intraoperative use of silicone oil and postoperative occurrence of GRAE, defined as elevated intraocular pressure (>21 mmHg), initiation of pressure-lowering medications, performance of pressure-lowering surgery, or a diagnosis of childhood glaucoma based on the Childhood Glaucoma Research Network criteria.
Main Outcome Measures
Survival analysis of GRAE between patients exposed vs. not exposed to silicone oil during VR surgery.
Results
Of the 186 pediatric patients analyzed, 64 (34.4%) were exposed to silicone oil, and 102 developed GRAE (54.8%). Median survival time to GRAE was 2.0 months (95% confidence interval [CI]: 0.3, 7.7) for silicone oil exposure in patients vs. 25.3 months (95% CI: 3.6, N/A) for patients not exposed to silicone oil (P = 0.0045). Patients exposed to silicone oil had a 52% increased risk of GRAE compared to those not exposed to silicone oil when adjusted for age at VR surgery (hazard ratio: 1.52 [95% CI: 1.01, 2.28], P = 0.0425).
Conclusions
In this exploratory study, GRAE was commonly observed following pediatric VR surgery, particularly in patients exposed to silicone oil. These findings underscore the importance of careful glaucoma surveillance following VR surgery in children.

To evaluate the location-specific association of deep optic nerve head (ONH) structures and background characteristics with visual field (VF) sensitivity in eyes with peripapillary intrachoroidal cavitation (PICC).
Design
A prospective cross-sectional study.
Subjects
One hundred twenty-nine eyes of 93 consecutive cases with PICC determined on fundus photographs and confirmed on OCT.
Methods
Peripapillary intrachoroidal cavitation location was determined on ONH-centered OCT radial slices according to Garway-Heath sectors. Visual field defect (VFD) corresponding to the location of the PICC sector was considered absent when the pattern deviation probability plot showed no point with a probability < 1% within the corresponding 24-2 Humphrey VF sector. Sectoral mean total deviation (TD) was calculated for structure–function analysis. The presence of full-thickness retinal defect was determined, and PICC depth and deep ONH parameters were calculated with OCT slices.
Main Outcome Measures
A best-fit multivariable linear mixed model was applied to identify factors associated with sectoral mean TD corresponding to PICC location. Explanatory variables included age, sex, axial length, intraocular pressure, presence of full-thickness retinal defect, circumpapillary retinal nerve fiber layer thickness (cpRNFLT), PICC depth, Bruch membrane opening (BMO) area, scleral flange opening (SFO) area, and SFO/BMO offset magnitude.
Results
Among 254 sectors with PICC, 136 sectors (54%) did not present corresponding VFD. Suspected VFD was most frequent in the temporal (34/50, 68%) and inferior temporal (67/104, 64%) sectors. In the best-fit multivariable analysis, worse sectoral TD in the PICC sectors was associated with the presence of full-thickness retinal defect (P = 0.036) and thinner cpRNFLT (P < 0.001) but was not associated with PICC depth or other deep ONH parameters.
Conclusions
Although PICC alone did not necessarily cause corresponding VFD, PICC in the temporal sectors should be carefully examined for VFD. Full-thickness retinal defect, a myopia-induced tissue disruption, and cpRNFLT thinning at the PICC location were significantly associated with worse VF, whereas PICC size and other myopia-related deep ONH structural changes were not. Identification of these factors provides a foundation for understanding VF sensitivity reduction in eyes with characteristically highly myopic ONH changes.

Purpose
Sepetaprost is a novel investigative prodrug, the active form of which is a dual agonist targeting both prostaglandin F receptors and prostaglandin E receptor 3. This study (NCT04742283) aimed to demonstrate the noninferiority of sepetaprost ophthalmic solution 0.002% to timolol maleate ophthalmic solution 0.5% in participants with primary open-angle glaucoma (POAG) or ocular hypertension (OHT).
Design
A phase IIb, randomized, double-masked, active-controlled, multicenter study conducted in the United States.
Participants
In total, 323 adult (≥18 years) participants (POAG, 68.4%; OHT, 31.6%) were randomized 1:1 to receive either once-daily sepetaprost (n = 162) or twice-daily timolol (n = 161) in 1 eye for 3 months.
Methods
Intraocular pressure (IOP) was measured at 3 timepoints (8:00 am, 10:00 am, and 4:00 pm) at 3 visits (weeks 2 and 6 and month 3).
Main Outcome Measures
The primary efficacy endpoint was noninferiority of sepetaprost to timolol. Noninferiority was established if the upper limit of the 2-sided 95% confidence interval (CI) for the difference in mean IOP (sepetaprost minus timolol) was ≤1.5 mmHg at all 9 specified timepoints and ≤1.0 mmHg at 5 or more of the 9 timepoints. Superiority was tested if noninferiority was achieved. Safety, including adverse events (AEs) and suspected adverse reactions, was evaluated throughout.
Results
The primary endpoint, the noninferiority of sepetaprost to timolol in mean IOP reductions, was met. The upper limit of the 2-sided 95% CI for the between-group difference in mean IOP score was <1.0 mmHg at all 9 timepoints. Superiority of sepetaprost to timolol was observed at 4:00 pm in week 2, week 6, and month 3; IOP mean difference (standard error): −0.76 (0.302), –0.73 (0.328), and −0.95 (0.319), respectively (all P < 0.05). Overall, 23.6% of participants receiving sepetaprost and 21.3% receiving timolol experienced AEs. The most commonly reported ocular AE in both groups was conjunctival hyperemia (sepetaprost, 9.9%; timolol, 2.5%).
Conclusions
Once-daily sepetaprost 0.002% was statistically noninferior to twice-daily timolol 0.5% for lowering IOP in participants with POAG or OHT. There were no unexpected safety concerns observed, and all AEs were mild or moderate in severity.

Purpose
To evaluate the effectiveness and safety of gonioscopy-assisted transluminal trabeculotomy (GATT) in managing early-onset glaucoma secondary to Sturge–Weber syndrome (SWS).
Design
A retrospective interventional case series.
Participants
Medical records of 16 patients (22 eyes) diagnosed with early-onset glaucoma secondary to SWS who underwent GATT surgery were reviewed.
Methods
All patients underwent GATT surgery using a 5-0 or 6-0 prolene suture under general anesthesia.
Main Outcome Measures
The primary outcomes were intraocular pressure (IOP) reduction, complete surgical success (IOP ≤ 18 mmHg without medications), qualified surgical success (IOP ≤ 18 mmHg with medications), and postoperative complications.
Results
The mean IOP decreased significantly from 25.4 ± 4.8 mmHg at baseline to 15.7 ± 4.2 mmHg at the final follow-up (P < 0.001), representing a 38.19% reduction. The mean age at the time of GATT surgery was 33.6 ± 33.9 months. The mean follow-up duration was 16.3 ± 6.4 months. Complete surgical success was achieved in 45.4% of eyes (10 out of 22), while qualified success was reached in 81.8% of eyes (18 out of 22). Despite the overall success, 18.1% of eyes (4 eyes) required additional surgical interventions during the follow-up period. These included Ahmed glaucoma valve implantation in 1 eye, trabeculectomy in 2 eyes, and transscleral diode laser cyclophotocoagulation in 1 eye. Transient hyphema was the only reported complication, resolving spontaneously within 1 week without further intervention.
Conclusions
Gonioscopy-assisted transluminal trabeculotomy appears to be a promising surgical option for managing early-onset glaucoma in patients with SWS, offering significant IOP reduction and a favorable safety profile within the limitations of our study. However, further studies with longer follow-up periods and comparative groups are necessary to confirm these findings.

Purpose
To compare the structural changes in the peripapillary and macular regions following pars plana vitrectomy (PPV) with epiretinal membrane (ERM) peeling between nonglaucomatous eyes and eyes with primary open-angle glaucoma (POAG).
Design
A retrospective, longitudinal, observational study.
Participants
Sixty-eight eyes (34 POAG and 34 nonglaucomatous eyes) that underwent PPV with ERM peeling surgery.
Methods
This retrospective study analyzed 68 eyes (34 POAG and 34 nonglaucomatous eyes) that underwent PPV with ERM peeling surgery. The circumpapillary retinal nerve fiber layer (RNFL) thickness, central macular thickness (CMT), and interdigitation zone (IZ) defects were assessed using spectral-domain OCT before and 6 months after surgery and compared between nonglaucomatous and POAG eyes.
Main Outcome Measures
Comparison of structural changes between POAG eyes and nonglaucomatous eyes after PPV with ERM peeling surgery.
Results
Both nonglaucomatous and POAG eyes showed significant reductions in CMT and temporal RNFL thicknesses postoperatively, but significant increases were observed in nasal RNFL thicknesses. However, the changes were less prominent in POAG eyes, with significantly smaller decreases in CMT (P = 0.044) and temporal RNFL thickness (P = 0.020), and smaller increases in the nasal (P = 0.022) and inferonasal (P = 0.005) RNFL thicknesses. In nonglaucomatous eyes, the length of the IZ defect decreased significantly postoperatively (P = 0.009), while no significant change was observed in POAG eyes (P = 0.115).
Conclusions
Structural changes in the macula and peripapillary areas following PPV with ERM peeling were less pronounced in POAG eyes than in nonglaucomatous eyes, probably due to preexisting optic nerve damage. These different structural outcomes should be considered in the diagnosis and monitoring of patients with glaucoma accompanied by ERM.

Purpose
To test the association between use of calcium channel blocker (CCB) medications and the rate of visual field (VF) progression in a large cohort of patients from 5 glaucoma clinics.
Design
Retrospective longitudinal case-control study.
Subjects
Patients attending 5 glaucoma clinics in the United Kingdom using the same electronic medical record (EMR) system.
Methods
For the main analysis, we selected 1 eye from patients with at least 5 reliable (false positive errors < 15%) VFs over a period of at least 4 years. The use of systemic medications was derived from the EMR system. Calcium channel blocker users were identified as cases. Propensity score matching (PSM) and multivariable analyses (MVAs) were used to adjust for confounders. A directed acyclic graph of the relevant variables guided the selection of covariates. Linear mixed-effect models (LMMs) were used to test the effect on the rate of VF mean deviation (MD) associated with CCB use and other covariates (for the MV analysis). Sensitivity analyses were conducted with different inclusion criteria and cutoffs on the estimated duration of CCB use.
Main Outcome Measures
The mean difference in the rate of VF MD progression between CCB users and controls.
Results
The main analysis included 14 475 eyes (1942 from CCB users) that met the selection criteria (1 eye per patient). The median (interquartile range) VF series length was 8 (6, 11) tests, with a follow-up of 8.6 (6, 11.5) and 8.2 (5.9, 11.2) years in CCB users and controls, respectively. One-to-one PSM pairing with controls was achieved for all CCB users. The estimated rate of MD progression was −0.31 (−0.33 to −0.28) dB/year (mean [95% confidence intervals]) in the CCB users and −0.35 (−0.37 to −0.33) dB/year in the matched controls (P = 0.016). This significant difference was confirmed with the MV analysis including all controls (P = 0.020). All sensitivity analyses confirmed the main results.
Conclusions
Calcium channel blocker use was statistically significantly associated with a slower rate of VF deterioration after multivariable adjustment. The estimated difference was small and likely not clinically significant but may be influenced by the limited information on the duration of CCB exposure in this cohort.

Purpose
To compare retinal nerve fiber layer (RNFL) thickness rates of change and their variability between 2 commercial OCT devices.
Design
Prospective cohort study.
Participants
Ninety-four glaucoma eyes (94 patients) with central damage or moderate to advanced glaucoma with ≥ 2 years of follow-up and ≥ 4 pairs of OCT scans.
Methods
A bivariate longitudinal Bayesian model was designed to compare inferences on RNFL rates of change from the 2 devices, both globally and in 12 clock hour sectors. Optic nerve OCT scans were acquired with Spectralis and Cirrus OCT devices in the same session. We inspected longitudinal RNFL profile plots from both OCT devices for all subjects across all sectors and globally.
Main Outcome Measures
The rates of change, longitudinal variances, and proportions of significant negative and positive slopes (slope < 0 or > 0 μm/year and 1-sided P < 0.025, respectively) were compared between the devices.
Results
The mean (standard deviation) baseline 24-2 visual field mean deviation and median (range) follow-up time were −8.2 (5.5) dB and 4.5 (2.2–6.7) years, respectively. The mean (95% credible interval [CrI]) estimated global baseline RNFL thickness for Spectralis and Cirrus OCTs were 61.5 (58.6–64.1) and 65.3 (63.2–67.4) μm, respectively. The global RNFL rates of change for Spectralis and Cirrus OCTs were −0.70 μm/year (95% CrI = −0.88 to −0.51 μm/year) and −0.45 μm/year (95% confidence interval = −0.63 to −0.27 μm/year) and were significantly faster for Spectralis compared to Cirrus OCT (difference = –0.24 μm/year, 95% CrI −0.45 to −0.04 μm/year, P < 0.001) as were sectoral rates in 5 out of 12 sectors. Higher proportions of significant negative RNFL rates of change were found with Spectralis OCT globally and in clock hour sectors 2 to 6 and 8 to 10 (corresponding to nasal, inferonasal, inferotemporal, and temporal regions). The proportions of significant positive rates of change were small (0%–3%) across sectors and similar between the devices.
Conclusions
Spectralis OCT rates of RNFL change were faster compared to those from Cirrus OCT. Spectralis OCT detected a higher proportion of significant negative rates globally and in some sectors. OCT devices are not comparable regarding detection of change in eyes with central damage or moderate to advanced glaucoma.

Topic
The National Institutes of Health (NIH) issued guidance in 2016 that sex should be treated as a biological variable in clinical studies; however, previous research has shown that biomedical studies still fail to include sex as a biological variable (SABV) in study design and analysis. We hypothesize that despite evidence for sex-specific glaucoma risk factors, clinical trials for glaucoma topical medications also fail to treat SABV.
Clinical Relevance
Prior studies have found sex-specific genetic and hormonal risk factors for glaucoma suggesting that biological sex may influence the disease course.
Methods
We performed a systematic review on Pubmed and Google Scholar using terms including generic names of common glaucoma medications, and filters “randomized control trial” and “clinical trial.” Resulting studies were reviewed and included if they met inclusion criteria including randomized controlled trial design, testing of topical glaucoma medications in patients with open-angle glaucoma or ocular hypertension, and published between 2002-2022. Included studies were read and assessed on metrics pertinent to SABV including sex reporting and matching, sex-based analysis of medication efficacy, adverse events (AEs), and mention of SABV in the discussion and conclusion.
Results
We identified 543 studies; 122/543 (22.5%) met inclusion criteria representing 31 644 subjects; 16 656/31 644 (52.6%) were women. Sex of subjects was reported in 109/122 (89%) studies. However, only 5/122 (4%) mentioned sex in data analysis, including efficacy (1), AEs (1), and mention of sex in the discussion or conclusion (4). We found that studies published after the NIH guidance on SABV in 2016 and studies funded by the NIH were not more likely to include SABV, however only 3 of 122 (2.5%) studies were NIH-funded. Pregnancy or lactation were exclusion criteria for 31/122 (25%) studies.
Conclusions
While the majority of glaucoma topical medication clinical trials reported sex and achieved sex-matching, they failed to include sex-based analysis of medication efficacy or AEs. Opportunities remain to include SABV to improve our understanding of the impact of biological sex on glaucoma treatment, although that may require increases in sample size.
