RESUMEN
PRECIS: Among 1,861 adults with ocular hypertension or mild or moderate primary open-angle glaucoma, those with Medicaid or no insurance had a statistically significantly lower likelihood of receiving laser trabeculoplasty compared with those with other insurance. PURPOSE: To determine whether social determinants of health are associated with undergoing treatment with laser trabeculoplasty (LTP) among individuals with ocular hypertension (OHT) or mild or moderate primary open angle glaucoma (POAG). METHODS: In this cross-sectional study, we included patients with OHT or mild or moderate POAG from the National Institutes of Health All of Us Research Program, a diverse US nationwide dataset. Logistic regression was performed to study the association between LTP treatment status and seven covariates (diagnosis severity, age, gender, race/ethnicity, income, insurance status, and education). RESULTS: 1,861 subjects were included (median age of 72 y). In univariable logistic regression, diagnosis severity, older age, higher income, and insurance (non-Medicaid) were associated with LTP treatment. On multivariable logistic regression models, those with mild POAG (OR, 3.49; 95% CI [2.12-5.87]) and moderate POAG (OR, 7.15 [4.49-11.8]) were still more likely than OHT patients to have received LTP. Moreover, compared with participants with Medicaid or no insurance, participants with other insurance (e.g. employer provided, Medicare) were still more likely to have received LTP (OR, 2.24 [1.08-5.29]). There was no significant difference in the LTP treatment likelihood based on race/ethnicity. CONCLUSIONS: After controlling for confounders, the likelihood of receiving LTP appears to be driven primarily by insurance rather than income or race/ethnicity. Potential reasons for decreased utilization of LTP among Medicaid patients include higher rates of declining the procedure, or LTP may have been offered less frequently due to Medicaid's lower levels of reimbursement and longer reimbursement delays.
RESUMEN
PURPOSE: To describe the incidence, risk factors, clinical characteristics, and long-term outcomes of a hypertensive phase (HP) after glaucoma drainage device (GDD) implantation. DESIGN: Retrospective cohort study. PARTICIPANTS: Eyes that underwent implantation of their first GDD from January 2010 to October 2020 at a tertiary care center. METHODS: Hypertensive phase was defined as intraocular pressure (IOP) >21 mmHg occurring at 2 consecutive visits in the first 90 days after the date of surgery for Ahmed Glaucoma Valve (AGV) or in the first 90 days after tube opening for Baerveldt Glaucoma Implant (BGI). Generalized estimating equations and Fisher exact tests were used to evaluate risk factors for HP and risk factors for failure of GDD surgery after occurrence of a HP. MAIN OUTCOME MEASURES: Incidence and risk factors for HP. Overall surgical success rates, defined as the absence of failure criteria: IOP >21 mmHg, ≤5 mmHg, or <20% reduction below baseline IOP after 3 months for 2 consecutive visits, with or without adjunctive ocular hypotensive therapy; additional glaucoma surgery; or loss of light perception. RESULTS: Among 419 eyes of 360 patients that underwent GDD implantation, 42 (10.0%) eyes developed HP. Onset of HP was 20.8 ± 10.5 days after AGV and 11.7 ± 20.3 days from the date of tube opening after BGI. Mean IOP during HP was 26.5 ± 3.2 mmHg with peak IOP of 30.0 ± 5.9 mmHg. Median follow-up duration was 21.5 months after onset of HP. Younger age and neovascular glaucoma were significant risk factors for HP occurrence in a multivariable model. Resolution of HP occurred in 32 eyes (76.2%) after a mean duration of 48.0 ± 53.0 days. Additional surgery with a second GDD or cyclophotocoagulation was performed for 12 eyes (28.6%). The overall success rate among eyes with a HP was 52.6% at 2 years, which was significantly lower than that observed among control eyes that did not experience HP (76.3%), P < 0.01. CONCLUSIONS: The incidence of HP was 10.0%. Younger age and neovascular glaucoma were significant risk factors for HP in the multivariable model. The risk of surgical failure after HP is significantly higher compared to eyes that did not experience HP.

PRCIS: Intraluminal 3-0 Supramid stent placement can be an effective long-term solution for hypotony after glaucoma drainage device surgery. This procedure may obviate the need for conjunctival dissection. In some cases, additional procedures are required. PURPOSE: To describe the utility of implantation of a multifilament polyamide suture (Supramid) in the tube lumen to reverse hypotony after glaucoma drainage device (GDD) surgery. PATIENTS: Patients who underwent tube revision with intraluminal placement of a 3-0 Supramid stent, with or without external ligature, to manage hypotony following GDD surgery between January 2010 and October 2020. METHODS: Resolution of hypotony was defined as IOP >5 mm Hg and the absence of hypotony-related structural abnormalities. Overall success was the absence of failure criteria (IOP ≤5 mm Hg, >21 mm Hg, or <20% reduction below baseline IOP after 3 months for 2 consecutive study visits; additional glaucoma surgery; or loss of light perception), with or without adjunctive ocular hypotensive therapy. RESULTS: Nine eyes of 9 patients underwent placement of a 3-0 Supramid stent with a resolution of hypotony in all eyes with a mean follow-up duration of 33.3 ±24.0 months. Overall success was achieved in 7 of 9 eyes. Four eyes required intervention after stent placement: 1 eye required selective laser trabeculoplasty followed by replacement of the original stent with a shorter 3-0 Supramid suture and external ligature; 1 eye underwent revision for tube exposure; and 2 eyes underwent laser suture lysis to release an external suture ligature. CONCLUSIONS: In cases of hypotony after GDD, particularly when it is desirable to reduce the extent of additional conjunctival dissection, intraluminal placement of a 3-0 Supramid stent via an intracameral approach can be an effective long-term solution. Postoperative adjustments were required in many cases.

PRCIS: A deep learning model trained on macular OCT imaging studies detected clinically significant functional glaucoma progression and was also able to predict future progression. OBJECTIVE: To use macular optical coherence tomography (OCT) imaging to predict the future and detect concurrent visual field progression, respectively, using deep learning. DESIGN: A retrospective cohort study. SUBJECTS: A pretraining data set was comprised of 7,702,201 B-scan images from 151,389 macular OCT studies. The progression detection task included 3902 macular OCT imaging studies from 1534 eyes of 828 patients with glaucoma, and the progression prediction task included 1346 macular OCT studies from 1205 eyes of 784. METHODS: A novel deep learning method was developed to detect glaucoma progression and predict future progression using macular OCT, based on self-supervised pretraining of a vision transformer (ViT) model on a large, unlabeled data set of OCT images. Glaucoma progression was defined as a mean deviation (MD) rate of change of ≤ -0.5 dB/year over 5 consecutive Humphrey visual field tests, and rapid progression was defined as MD change ≤ -1 dB/year. MAIN OUTCOME MEASURES: Diagnostic performance of the ViT model for prediction of future visual field progression and detection of concurrent visual field progression using area under the receiver operating characteristic curve (AUC), sensitivity, and specificity. RESULTS: The model distinguished stable eyes from progressing eyes, achieving an AUC of 0.90 (95% CI, 0.88-0.91). Rapid progression was detected with an AUC of 0.92 (95% CI, 0.91-0.93). The model also demonstrated high predictive ability for forecasting future glaucoma progression, with an AUC of 0.85 (95% CI 0.83-0.87). Rapid progression was predicted with an AUC of 0.84 (95% CI 0.81-0.86). CONCLUSIONS: A deep learning model detected clinically significant functional glaucoma progression using macular OCT imaging studies and was also able to predict future progression. Early identification of patients undergoing glaucoma progression or at high risk for future progression may aid in clinical decision-making.

PURPOSE: To compare outcomes of early aqueous suppression (EAS) and standard therapy (ST) after Ahmed Glaucoma Valve (AGV) implantation for uveitic glaucoma. DESIGN: Retrospective comparative cohort study. PARTICIPANTS: All patients with uveitic glaucoma underwent AGV implantation from January 2010 to October 2020 at Northwestern Medicine. METHODS: Excluding the first postoperative day 1 (POD1), only eyes with IOP 10-15 mmHg at their first visit with IOP ≥ 10 mmHg were included in the main analysis. Early aqueous suppression (EAS) was defined as initiation of ocular hypotensive therapy when IOP was first 10-15 mmHg. Standard therapy was initiation of therapy at any later time. Failure was defined as IOP > 21 mmHg, < 5 mmHg, or < 20% reduction in IOP from baseline after 3 months, for 2 consecutive study visits. Hypotony was defined as IOP ≤ 5 mmHg for ≥ 2 visits. Hypertensive phase was defined as IOP > 21 mmHg for 2 consecutive visits in the first 3 months. MAIN OUTCOME MEASURES: Proportion achieving overall success; incidence of hypotony and hypertensive phase. RESULTS: Twenty-eight eyes of 26 patients were in the EAS group and 20 eyes of 19 patients were in the ST group, with a mean follow-up of 17.7 and 28.2 months, respectively. Baseline IOP was similar in the EAS (31.2 ± 10.1 mmHg) and ST (34.6 ± 12.2 mmHg) groups; P = 0.18. Final IOP was lower in the EAS group (12.9 ± 4.6 mmHg) than the ST group (16.4 ± 5.7 mmHg; P = 0.02) on 2.6 ± 0.9 medications in the EAS group and 1.8 ± 1.5 in the ST group (P = 0.07). Overall success was achieved in 87% of EAS eyes and 74% of ST eyes (P = 0.43). There were no statistically significant differences in the occurrence of additional glaucoma surgery (4% for EAS, 20% for ST; P = 0.11), hypotony (7% for EAS, 0% for ST; P = 0.50), or hypertensive phase (4% for EAS, 21% for ST; P = 0.09). CONCLUSIONS: EAS was associated with a lower final IOP after AGV in uveitic glaucoma eyes; however, more medications were in use at the final visit. No statistically significant differences in overall success or the incidence of adverse events were observed.

PRCIS: The cost of cyclophotocoagulation is less than the cost of a second glaucoma drainage device. PURPOSE: To compare the total direct costs of implantation of a second glaucoma drainage device (SGDD) with transscleral cyclophotocoagulation (CPC) for patients with inadequately controlled intraocular pressure (IOP) reduction, despite the presence of a preexisting glaucoma drainage device in the ASSISTS clinical trial. METHODS: We compared the total direct cost per patient, including the initial study procedure, medications, additional procedures, and clinic visits during the study period. The relative costs for each procedure during the 90-day global period and the entire study period were compared. The cost of the procedure, including facility fees and anesthesia costs, were determined using the 2021 Medicare fee schedule. Average wholesale prices for self-administered medications were obtained from AmerisourceBergen.com. The Wilcoxon rank sum test was used to compare costs between procedures. RESULTS: Forty-two eyes of 42 participants were randomized to SGDD (n=22) or CPC (n=20). One CPC eye was lost to follow-up after initial treatment and was excluded. The mean (±SD, median) duration of follow-up was 17.1 (±12.8, 11.7) months and 20.3 (±11.4, 15.1) months for SGDD and CPC, respectively ( P =0.42, 2 sample t test). The mean total direct costs (±SD, median) per patient during the study period were $8790 (±$3421, $6805 for the SGDD group) and $4090 (±$1424, $3566) for the CPC group ( P <0.001). Similarly, the global period cost was higher in the SGDD group than in the CPC group [$6173 (±$830, $5861) vs. $2569 (±$652, $2628); P <0.001]. The monthly cost after the 90-day global period was $215 (±$314, $100) for SGDD and $103 (±$74, $86) for CPC ( P =0.31). The cost of IOP-lowering medications was not significantly different between groups during the global period ( P =0.19) or after the global period ( P =0.23). CONCLUSION: The total direct cost in the SGDD group was more than double that in the CPC group, driven largely by the cost of the study procedure. The costs of IOP-lowering medications were not significantly different between groups. When considering treatment options for patients with a failed primary GDD, clinicians should be aware of differences in costs between these treatment strategies.

PRCIS: Among 7846 adults with self-reported glaucoma, low health literacy (LHL) was associated with fewer outpatient ophthalmological follow-up visits, utilization of a greater number of ocular hypotensive medication classes, and higher costs for glaucoma medications. PURPOSE: Previous studies found LHL is associated with increased difficulty with treatment adherence among adults with glaucoma, which can lead to poor outcomes. This study examined patterns of glaucoma health care utilization associated with LHL. METHODS: We analyzed 7846 adults with self-reported glaucoma enrolled in the 1996-2017 Medical Expenditure Panel Survey. Adult glaucoma patients with LHL (defined by National Assessment of Adult Literacy score <226) were the compared with those with high health literacy. Multivariable regression models were constructed to examine the association of LHL with number of outpatient glaucoma visits, prescription medications, polypharmacy (≥2 ocular hypotensive classes prescribed), and associated costs. RESULTS: Self-reported glaucoma diagnosis was associated with higher rates of LHL [23.9% vs. 9.7%, odds ratio (95% CI): 2.43 (2.25-2.62), P <0.0001]. Among those with glaucoma, LHL was associated with fewer glaucoma outpatient visits [risk ratio: 0.94 (0.89-0.99), P =0.02] and the use of a greater number of ocular hypotensive medications [1.06 (1.01-1.12), P =0.03]. Moreover, those with LHL had higher health care spending on prescription medications [mean: $556.40 vs. $471.87, ß (95% CI): $57.05 ($30.22-$83.87)]. Adult glaucoma patients with LHL were also more likely to have polypharmacy [odds ratio (95% CI): 1.26 (1.01-1.59)]. CONCLUSION: LHL was more prevalent in patients with glaucoma, compared with those without. Glaucoma patients with LHL were prescribed more medications and had higher medication costs, however, they had fewer outpatient glaucoma visits. Improved glaucoma patient education to address LHL is needed, in addition to studies to understand the impact of these findings on treatment outcomes.

Purpose: The purpose of this report is to describe a case of a patient with microspherophakia (MSP) who had a scleral rupture during a retinal detachment (RD) repair with primary scleral buckle and cryoretinopexy. Observations: A 48-year-old woman with MSP presented with six days of expanding loss of vision and photopsias. Examination revealed a superior retinal detachment involving the macula associated with two superior retinal tears. The patient underwent successful placement of a segmental buckle. During cryoretinopexy treatment of the tears, a 4 mm full-thickness scleral rupture occurred. The sclera was immediately closed with interrupted 8-0 nylon sutures and reinforced with a processed pericardium allograft. Subsequent combined phacoemulsification with capsulectomy, zonulectomy, and pars plana vitrectomy with retinal reattachment was performed nine days post buckle placement. Conclusions and importance: This case illustrates that a patient with MSP, even observed in the absence of a genetic syndrome or familial condition, may be at increased risk of scleral rupture during RD repair. Though future investigations are necessary to confirm this association, surgeons should take a conservative approach by having a high clinical suspicion for compromised scleral integrity in patients with MSP and proceeding with caution in procedures that may pose a risk of scleral rupture. A pericardium allograft can be an effective adjunct for scleral rupture repair.
RESUMEN
PRCIS: Short-term overall success rates were high with either SGDD or CPC. However, SGDD was associated with more clinic visits and an increased risk of additional glaucoma surgery. Both treatments were reasonable options for eyes with inadequately controlled IOP after a single GDD. PURPOSE: The purpose of this study is to compare the implantation of a second glaucoma drainage device (SGDD) and transscleral cyclophotocoagulation (CPC) in eyes with inadequately controlled intraocular pressure (IOP), despite the presence of a preexisting glaucoma drainage device. METHODS: Patients with inadequately controlled IOP, despite the medical therapy and a preexisting glaucoma drainage device, were enrolled at 14 clinical centers and randomly assigned to treatment with a SGDD or CPC. MAIN OUTCOME MEASURES: Surgical failure was defined as: (1) IOP ≤5 mm Hg or >18 mm Hg or <20% reduction below baseline on maximum tolerated topical ocular hypotensive therapy, (2) reoperation for glaucoma, or (3) loss of light perception. The primary outcome measure was overall success with or without adjunctive medical therapy. RESULTS: Forty-two eyes of 42 participants were randomized to SGDD (n=22) or CPC (n=20). Mean duration of follow-up was 18.6 (±12.1; range: 1.1-38.6) months. The cumulative success rate was 79% for SGDD and 88% for CPC at 1 year ( P =0.63). Although the study was underpowered, no significant differences in IOP, postoperative number of IOP-lowering medications, or adverse events were observed. The number of additional glaucoma surgeries ( P =0.003), office visits during the first 3 months ( P <0.001), and office visits per month after month 3 ( P <0.001) were greater in the SGDD group. CONCLUSIONS: Short-term overall success rates were high with either SGDD or CPC. However, SGDD was associated with more clinic visits and an increased risk of additional glaucoma surgery.

PRCIS: We assessed the readability of online glaucoma patient education materials using seven validated instruments. Overall, glaucoma materials were written at a 10th to 11th grade level, above the recommended seventh grade reading level. PURPOSE: Online health information is increasingly used by patients, yet previous studies show online patient education materials are often difficult to understand. As such, the American Medical Association recommends that patient education materials are written at or below a seventh grade reading level. This study aimed to assess the readability of online glaucoma patient education materials. METHODS: Glaucoma was entered into the Google search engine, and the first 30 search results were assessed for readability using seven validated readability instruments. Scientific articles, forums, and dictionary entries were excluded. Single sample t tests were used to assess whether online glaucoma materials were written above the recommended seventh grade level. RESULTS: Overall, glaucoma materials were written at a mean grade level of 10.33 (SD: 2.02). Across 6 grade level readability instruments, these patient education materials were written above the recommended seventh grade reading level (P<0.0001 for all). Glaucoma education materials only on the first page of Google search results were of a similar reading level: mean 10.56 (SD: 2.13). The readability instruments used in this study showed strong consistency. CONCLUSIONS: Glaucoma patient education materials are written above the recommended reading level to promote accessibility of education materials. This may contribute to lower patient engagement, worse clinical outcomes, and greater racial and ethnic disparities in glaucoma management. There is a need for reliable, simple glaucoma information to improve patient outcomes.

PURPOSE: To present a case of progressive ectropion uveae and secondary angle-closure glaucoma in association with type 1 neurofibromatosis (NF-1). OBSERVATION: An 11-year-old-Hispanic-male with a known history of NF-1 who was followed for the ocular manifestations of NF-1 developed an irregular pupil and ectropion uveae in the right eye at the age of 3 years that gradually increased in severity. The area of ectropion uveae increased in size and extended superiorly with concurrent superior synechial angle closure and intraocular pressure (IOP) elevation. The patient subsequently developed chronic angle-closure glaucoma that could not be controlled with medical therapy. He underwent successful implantation of an aqueous drainage device which resulted in excellent intraocular pressure reduction. CONCLUSIONS AND IMPORTANCE: Ectropion uveae can be progressive and lead to the development of extensive angle closure in patients with NF-1. Despite the low incidence of glaucoma in patients with NF-1, the presence of ectropion uveae in this condition necessitates careful observation of the anterior segment, including the anterior chamber angle and close monitoring of the IOP.
RESUMEN
PRCIS: The annual incidence of glaucoma progression (9.7%) and rates of visual field mean deviation (MD) change in progressors (-1.02±0.06 dB/y) are high in a small cohort of urban Ghanaians. PURPOSE: To report the incidence of glaucoma progression and the rate of visual field deterioration in a small cohort of Ghanaians. METHODS: One hundred ten subjects (204 eyes) diagnosed with glaucoma at a baseline population-based screening examination were re-examined a mean of 8.3±0.8 years later. Eyes were classified as having progressed if the optic disc alone, visual field alone or both showed significant glaucomatous changes on follow-up. Visual field MD was used to calculate the rate of visual field progression. RESULTS: Progression was observed in 89 (80.9%, 9.7%/year) subjects (130 eyes). Progression occurred in 32 (31.7%, 3.8%/year) subjects by optic disc alone (46 eyes), 38 (44.7%, 5.4%/year) subjects by visual field alone (58 eyes), and 19 (25.0%, 3.0%/year) subjects by both modalities (26 eyes). The average rate of change in MD differed significantly between progressors (-1.02±1.06 dB/y) and nonprogressors (+0.089±0.49 dB/y), P =0.001. The rate of visual field worsening was greater among those who were classified as having progressed by both structure and function (-1.29±0.68 dB/y) and by function alone (-1.21±1.20 dB/y) than by structure alone (-0.55±0.76 dB/y). Progression was significantly associated with older age [odds ratio (OR), 1.42; P <0.001] and higher baseline intraocular pressure (OR, 1.18; P =0.002). Factors associated with rate of MD change were baseline older age (OR, 1.66; P =0.003), higher intraocular pressure (OR, 2.81; P =0.007), better visual field MD (OR, 1.41; P =0.004), and systemic hypertension (OR, 1.15; P =0.029). CONCLUSION: The incidence and rate of visual field progression are high in this longitudinal study of Ghanaian subjects with glaucoma. The findings may have important clinical and public health policy ramifications.

PRCIS: Among patients with glaucoma or ocular hypertension, ineffective self-instillation of eye drops was associated with an increased long-term risk of progression or advancement of treatment to incisional surgery. PURPOSE: The purpose of this study was to evaluate the association between the efficacy of self-instillation of eye drops and long-term glaucoma outcomes. METHODS: In a previous study, video recordings of eye drop self-instillation by patients with glaucoma or ocular hypertension were graded as effective or ineffective depending on whether the patient successfully instilled at least 1 drop on the right ocular surface. Glaucomatous progression was then retrospectively defined as retinal nerve fiber layer thinning as measured by either optical coherence tomography, visual field progression, or need for incisional glaucoma surgery as determined by a glaucoma specialist unaware of patient performance in the eye drop instillation study. Subjects with at least 2 follow-up optical coherence tomography or visual field studies were included in the current study. RESULTS: The original study enrolled 119 patients. Sufficient follow-up data were available for 101 patients. Eighty-eight patients (87.1%) were effective in eye drop instillation at baseline. Mean follow-up was 5.1 years, during which time 73 patients (72.3%) had progression or underwent incisional surgery in either eye. A significantly higher proportion of patients in the ineffective group met the criteria for progression or underwent incisional surgery (effective: 68.2%; ineffective: 100%; N=101; P=0.017, Fisher exact test). Kaplan-Meier survival analyses showed a significantly faster time to reaching an endpoint in the ineffective group (N=101; P=0.012, log-rank test). There was no difference in age, baseline intraocular pressure, or baseline retinal nerve fiber layer thickness between the groups. CONCLUSION: Ineffective self-installation of eye drops was associated with an increased risk of glaucoma progression or treatment advancement to incisional surgery.

PURPOSE: To investigate the effect of systemic arterial blood pressure (BP) on rates of progressive structural damage over time in glaucoma. DESIGN: Retrospective cohort study. PARTICIPANTS: A total of 7501 eyes of 3976 subjects with glaucoma or suspected of glaucoma followed over time from the Duke Glaucoma Registry. METHODS: Linear mixed models were used to investigate the effects of BP on the rates of retinal nerve fiber layer (RNFL) loss from spectral-domain OCT (SD-OCT) over time. Models were adjusted for intraocular pressure (IOP), gender, race, diagnosis, central corneal thickness (CCT), follow-up time, and baseline disease severity. MAIN OUTCOME MEASURE: Effect of mean arterial pressure (MAP), systolic arterial pressure (SAP), and diastolic arterial pressure (DAP) on rates of RNFL loss over time. RESULTS: A total of 157 291 BP visits, 45 408 IOP visits, and 30 238 SD-OCT visits were included. Mean rate of RNFL change was -0.70 µm/year (95% confidence interval, -0.72 to -0.67 µm/year). In univariable models, MAP, SAP, and DAP during follow-up were not significantly associated with rates of RNFL loss. However, when adjusted for mean IOP during follow-up, each 10 mmHg reduction in mean MAP (-0.06 µm/year; P = 0.007) and mean DAP (-0.08 µm/year; P < 0.001) but not SAP (-0.01 µm/year; P = 0.355) was associated with significantly faster rates of RNFL thickness change over time. The effect of the arterial pressure metrics remained significant after additional adjustment for baseline age, diagnosis, sex, race, follow-up time, disease severity, and corneal thickness. CONCLUSIONS: When adjusted for IOP, lower MAP and DAP during follow-up were significantly associated with faster rates of RNFL loss, suggesting that levels of systemic BP may be a significant factor in glaucoma progression.
