RESUMO
Purpose: To predict 10-2 Humphrey visual fields (VFs) from 24-2 VFs and associated non-total deviation features using deep learning. Methods: We included 5189 reliable 24-2 and 10-2 VF pairs from 2236 patients, and 28,409 reliable pairs of macular OCT scans and 24-2 VF from 19,527 eyes of 11,560 patients. We developed a transformer-based deep learning model using 52 total deviation values and nine VF test features to predict 68 10-2 total deviation values. The mean absolute error, root mean square error, and the R2 were evaluation metrics. We further evaluated whether the predicted 10-2 VFs can improve the structure-function relationship between macular thinning and paracentral VF loss in glaucoma. Results: The average mean absolute error and R2 for 68 10-2 VF test points were 3.30 ± 0.52 dB and 0.70 ± 0.11, respectively. The accuracy was lower in the inferior temporal region. The model placed greater emphasis on 24-2 VF points near the central fixation point when predicting the 10-2 VFs. The inclusion of nine VF test features improved the mean absolute error and R2 up to 0.17 ± 0.06 dB and 0.01 ± 0.01, respectively. Age was the most important 24-2 VF test parameter for 10-2 VF prediction. The predicted 10-2 VFs achieved an improved structure-function relationship between macular thinning and paracentral VF loss, with the R2 at the central 4, 12, and 16 locations of 24-2 VFs increased by 0.04, 0.05 and 0.05, respectively (P < 0.001). Conclusions: The 10-2 VFs may be predicted from 24-2 data. Translational Relevance: The predicted 10-2 VF has the potential to improve glaucoma diagnosis.

PURPOSE: To evaluate factors associated with differences in intraocular pressure (IOP) readings between iCare and Goldmann applanation tonometry (GAT) in established glaucoma patients. METHODS: This retrospective comparative study included clinical data of 350 eyes from 350 established glaucoma patients who had iCare and GAT IOP measured by an ophthalmic technician and a glaucoma specialist, respectively. The main outcome measure was the difference in IOP measurements of the right eyes with iCare and GAT. RESULTS: The intraclass correlation coefficient (ICC) between GAT and iCare was 0.90. The mean IOP difference between tonometers was - 0.18 ± 2.89 mmHg. Bland-Altman plots indicated a 95% limit of agreement of - 5.8 to 5.5 mmHg. Central corneal thickness (CCT) and age were significantly correlated with the difference in IOPs of the iCare and GAT. GAT-IOP and age were significantly associated with the absolute difference in measured IOP of the two tonometers. The difference in measurements was not significantly associated with prior glaucoma surgery, average global index of optical coherence tomography, axial length, technician years of experience and certification, and IOP range. CONCLUSION: Although there is good agreement between the iCare and GAT mean values, these devices are not interchangeable in glaucoma patients due to the wide range of the limit of agreement.

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, 30-45â 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 ± 22.03â mJ vs. PG = 43.71 ± 25.68â 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.
RESUMO
PURPOSE OF REVIEW: The field of corneal biomechanics has rapidly progressed in recent years, reflecting technological advances and an increased understanding of the clinical significance of measuring these properties. This review will evaluate in-vivo biomechanical properties obtained by current technologies and compare them regarding their relevance to established biomechanical properties obtained by gold-standard ex-vivo techniques normally conducted on elastic materials. RECENT FINDINGS: Several new technologies have appeared in recent years, including vibrational optical coherence tomography (VOCT) and the corneal indentation device (CID). These techniques provide promising new opportunities for minimally invasive and accurate measurements of corneal viscoelastic properties. SUMMARY: Alterations in corneal biomechanics are known to occur in several corneal degenerative diseases and after refractive surgical procedures. The measurement of corneal biomechanical properties has the capability to diagnose early disease and monitor corneal disease progression. Several new technologies have emerged in recent years, allowing for more accurate and less invasive measurements of corneal biomechanical properties, most notably the elastic modulus.

Background: This retrospective review reports on patients who underwent glaucoma drainage implant (GDI) surgery and had baseline intraocular pressure (IOP) of ≤18 mmHg with at least one year of follow-up. Methods: Clinical data of 67 eyes of 67 patients were collected from patients' charts, and the outcomes of GDI were evaluated until 7 years. GDI failure was defined as IOP reduction of less than 20% from the baseline at two consecutive visits three months after surgery, decline to no light perception, or if additional glaucoma surgery was performed. Results: The average age was 65.9 ± 13.2 years. Most cases were male (52.2%), White (53.7%), and had primary open-angle glaucoma (62.7%). Forty-four eyes had prior glaucoma surgery (68.6%) and 46 (68.6%) had severe glaucoma. Though postoperative (postop) IOP changes were insignificant, the average postop number of medications dropped from 2.4 ± 1.4 to 1.9 ± 1.2 medications two years after surgery (p = 0.0451). Postop complications (23.9%) included GDI exposure (7.5%), inflammation (4.5%), shallow anterior chamber (4.5%), and strabismus (1.5%). Hypotony was observed in 4 eyes (5.9%), none of which developed hypotony maculopathy. The cumulative one-year failure rate was 56.7%, most of which were due to failure to lower IOP. Conclusion: In patients with baseline IOP ≤18 mmHg who had GDI surgery, though the change in IOP was not statistically significant, the number of medications dropped and visual field progression slowed in a subset of patients with adequate perimetric data. Due to a relatively high rate of complications and limited effectiveness in lowering IOP, GDI should be cautiously used in these eyes.
RESUMO
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.

PURPOSE: To compare early vs. delayed use of aqueous suppressants on Ahmed glaucoma valve (AGV) outcomes. DESIGN: Single-center retrospective comparative case series. PARTICIPANTS: Patients who underwent AGV surgery at Wills Eye Hospital in the period between 2016 and 2021. METHODS: Retrospective review of AGV surgery at Wills Eye Hospital 2016 to 2021 for refractory glaucoma. Two groups were created: group 1 or those who received early aqueous suppressant therapy in the first 2 weeks postoperatively whenever the intraocular pressure (IOP) was > 10 mmHg, and group 2 or those who received delayed treatment after 2 weeks whenever the IOP exceeded the target pressure. Aqueous suppressant therapy included topical beta blockers, carbonic anhydrase inhibitors, and/or alpha agonists. MAIN OUTCOME MEASURES: The primary outcome measures were the frequency of hypertensive phase (HP) defined as IOP > 21 mmHg in first 3 months after an initial reduction to 21 mmHg or less in the first postoperative week not caused by tube obstruction or retraction, and month-12 surgical failure defined as 5 ≥ IOP > 21 mmHg on 2 consecutive visits, vision decline to no light perception (NLP), or glaucoma reoperation. Secondary outcome measures included changes in visual acuity (VA), IOP, and glaucoma medications at 12 months. Predictive factors for surgical failure were also identified. RESULTS: A total of 407 eyes of 391 patients (260 in group 1, 147 in group 2) with similar baseline characteristics were included. Hypertensive phase was more common in group 2 than 1 (41.5% vs. 18.5%; P < 0.001). At month 12 (N = 303 eyes), group 1 was less likely to fail than group 2 (21.2% vs. 36.8%, P = 0.003). Multivariate regression analysis showed that HP (odds ratio [OR] = 10.47, P < 0.001), delayed aqueous suppression use (OR = 2.17, P = 0.003), and lower baseline VA (OR = 1.56, P = 0.015) were the strongest predictors of month-12 failure. CONCLUSIONS: Early use of aqueous suppressants may lower the risk of HP and improve AGV outcomes.

Purpose Despite easing restrictions on social distancing and travel since the beginning of coronavirus disease 2019 pandemic, virtual interviews remain a widely used format for ophthalmology fellowship interviews. This study aims to evaluate the relative benefits and drawbacks of in-person versus virtual interviews during a cycle where both formats were prevalent. Methods A prospective cross-sectional study surveyed all fellowship applicants ( N = 311) who applied to Wills Eye Hospital and Bascom Palmer Eye Institute during the 2022 to 2023 application cycle. Results A total of 59 (19%) applicants responded to the survey, with the majority being male (53.0%) and between the ages of 20 and 35 (91.3%). There was no statistically significant difference between the number of virtual and in-person interviews attended or the total number of interviews attended. The highest ranked limitations of the virtual interview process were limited exposure to details of the program structure, limited opportunity to exhibit applicants' strengths to the program, and limited exposure to the fellows. The highest ranked strengths were less pressure during interviews, greater scheduling flexibility, and ability to interview at more fellowship programs. The highest ranked limitations of the in-person interview process were more pressure during interviews, inability to interview at all desired fellowship programs, and decreased scheduling flexibility. The highest ranked strengths based on median rankings were greater exposure to details of the program structure, greater ability to exhibit an applicant's strengths to the program, and greater exposure to the geographic location/city. Conclusion While both in-person and virtual interviews have their own benefits and limitations, virtual interviews appear to be more cost-effective and time-efficient while in-person interviews provide better opportunities to assess program fit and culture. A hybrid format that combines the ideal aspects of both formats may be an optimal solution.
RESUMO
Purpose: To compare Ahmed glaucoma valve (AGV) outcomes in neovascular glaucoma (NVG) eyes with and without a postoperative (PO) hypertensive (HTN) phase. Design: Retrospective study at a single tertiary care center of patients who underwent AGV implantation for NVG treatment with ≥6-month follow-up. Methods: Main outcome measures included intraocular pressure (IOP), number of glaucoma medications (GM), and failure at month 6 or at the most recent visit. Failure was defined as decline to no light perception (NLP) vision, IOP >21 mm Hg, or need for glaucoma reoperations (all with GM). Results: A total of 76 eyes of 74 patients (37 without HTN phase and 39 with HTN phase) with a mean follow-up duration of 28.9 ± 25.7 months (p = 0.602) were included. Both groups had similar demographics, visual acuity (VA), number of GM, etiology of NVG, and retina treatment perioperatively. Baseline IOP was significantly higher in the HTN phase group (p = 0.001). Compared to eyes without an HTN phase, HTN phase eyes more commonly met failure criteria at month 6 (33.3 vs 9.1%; p = 0.01), but both groups had a comparable cumulative failure for the entire follow-up period (p = 0.180). At the most recent visit, the number of GM was higher in the HTN phase group (p = 0.019), but IOP was similar in both groups. PO complications were comparable and uncommon in both groups. Conclusion: Hypertensive (HTN) phase following AGV implantation for NVG is associated with higher preoperative IOP and greater failure by PO month (POM) 6. However, eyes with and without the HTN phase had similar needs for GM and failure rates over the long term. How to cite this article: Ramesh S, Shalaby WS, Myers JS, et al.

RESUMO
PURPOSE: To investigate the association between stereoacuity and the presence of central visual field defects (CVFDs) due to glaucoma. DESIGN: A prospective, cross-sectional cohort study. PARTICIPANTS: Participants with early-to-moderate glaucoma with a visual acuity better than 20/40, less than a 2-line difference in visual acuity between eyes, and 2 reliable Humphrey visual fields (VFs) (24-2 SITA standard) with mean deviation (MD) in the worse eye better than - 12 dB. METHODS: Stereoacuity was measured using the Titmus stereo test. Participants with a significant field defect (P < 0.005) in any 1 of the central 4 points in the 24-2 SITA standard total deviation map in either eye were classified as having a CVFD. Vision-related quality of life (VR-QOL) was measured using 25-item National Eye Institute Visual Function Questionnaire scores. Logistic regression was used to determine the associations between the level of stereoacuity and age, sex, race, glaucoma type, presence of CVFDs, visual acuity, contrast sensitivity, and VF MD. MAIN OUTCOME MEASURES: Stereoacuity in the CVFD and non-CVFD groups. RESULTS: Sixty-five participants met the inclusion criteria. The mean age of the participants was 64.3 ± 8.0 years, and 64.6% were women. The median stereoacuity was 60 arc seconds (interquartile range [IQR], 40-120 arc seconds). Forty-two (65%) patients had CVFDs, and 23 (35%) patients did not. The median stereoacuity of the CVFD group was worse than that of the non-CVFD group (60 arc seconds [IQR, 50-140 arc seconds] vs. 40 arc seconds [IQR, 40-80 arc seconds], respectively; P = 0.001). The non-CVFD group had a higher percentage of participants with normal stereopsis than the non-CVFD group (61% vs. 21%, respectively; P = 0.001). A multivariable analysis found that the presence of CVFDs was associated with worse stereopsis levels (odds ratio, 4.49; P = 0.021). The CVFD group had a lower Visual Functioning Questionnaire-25 (VFQ-25) composite score (84.0 vs. 91.4; P = 0.004) and lower VFQ-25 subscale scores for general vision, near activities, and mental health (P < 0.05). CONCLUSIONS: Central visual field defects were associated with increased odds of poor stereoacuity in patients with early-to-moderate glaucomatous VF loss. Specifically, patients without CVFDs are more likely to have normal stereopsis and higher VR-QOL than those with CVFDs. Patients with CVFDs should be counseled regarding how depth perception difficulties may affect daily living.

PURPOSE: To report 10-year clinical outcomes of tube shunt (TS) surgery at a tertiary care center. DESIGN: Retrospective cohort study. METHODS: Eyes were included that underwent a first TS surgery between January 2005 and December 2011 at a tertiary referral eye hospital and with at least 10 years of follow-up. Demographic and clinical data were collected. Failure was defined as reoperation to lower intraocular pressure (IOP), IOP > 80% of baseline for two consecutive visits, or progression to no light perception. RESULTS: Eighty-five eyes of 78 patients were included in the Study Group; 89 eyes were selected as a Comparison Group. Mean follow-up was 11.9 ± 1.7 years. Fifty-one valved (60%), 25 non-valved (29%), and nine unknown (11%) TS were placed. At the final visit, mean IOP was reduced from 29.2 ± 10.4 mmHg on 3.1 ± 1.2 medications to 12.6 ± 5.8 mmHg on 2.2 ± 1.4 (p<0.001 for each). Forty-eight eyes (56%) failed; 29 eyes (34%) underwent additional glaucoma surgery; eight eyes (10%) progressed to no light perception; and 34 eyes (40%) also required TS revision. Best corrected visual acuity (BCVA) logMAR (minimal angle of resolution) worsened from 0.8 ± 0.7 (20/125) to 1.4 ± 1.0 (20/500) at the last visit (p<0.001). Average visual field MD was -13.9 ± 7.5 dB at baseline and -17.0 ± 7.0 dB at last follow-up (P=0.0605). CONCLUSIONS: Many eyes maintained IOP control 10 years following TS, but 56% met failure criteria, 39% had substantial vision loss, and 34% underwent additional surgery. Outcomes did not differ with TS model. NOTE: Publication of this article is sponsored by the American Ophthalmological Society.

PURPOSE: To determine baseline patient characteristics that predict the need for glaucoma surgery or blindness in eyes with neovascular glaucoma (NVG) despite intravitreal antivascular endothelial growth factor therapy. METHODS: This is a retrospective cohort study of patients with NVG who had not previously received glaucoma surgery and were treated with intravitreal antivascular endothelial growth factor injections at the time of diagnosis, from September 8, 2011, to May 8, 2020, at a large, retina subspecialty practice. RESULTS: Of 301 newly presenting NVG eyes, 31% required glaucoma surgery and 20% progressed to no light perception vision despite treatment. Patients with intraocular pressure >35 mmHg ( P < 0.001), two or more topical glaucoma medications ( P = 0.003), worse than 20/100 vision ( P = 0.024), proliferative diabetic retinopathy ( P = 0.001), eye pain or discomfort ( P = 0.010), and new patient status ( P = 0.015) at the time of NVG diagnosis were at a higher risk of glaucoma surgery or blindness regardless of antivascular endothelial growth factor therapy. The effect of panretinal photocoagulation was not statistically significant in a subgroup analysis of patients without media opacity ( P = 0.199). CONCLUSION: Several baseline characteristics at the time of presentation to a retina specialist with NVG seem to portend a higher risk of uncontrolled glaucoma despite the use of antivascular endothelial growth factor therapy. Prompt referral of these patients to a glaucoma specialist should be strongly considered.

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.

PURPOSE: To assess the outcomes of glaucoma surgery in patients with a history of scleritis at a tertiary medical center. METHODS: The retrospective case series included patients with a history of scleritis who required glaucoma surgery between 4/2006 and 8/2021. RESULTS: Two hundred and eighty-one eyes of 259 patients had glaucoma and scleritis with 28 eyes (10%) of 25 patients requiring glaucoma surgery. Post-operatively, one eye (4%) had infectious scleritis. Eleven (39%) surgeries failed: 5 tube shunts, 5 cyclophotocoagulation, and 1 gonioscopy-assisted transluminal trabeculotomy. Five (18%) eyes required tube revisions due to tube exposures without infection (3), iris blocking the tube (1), or to shorten tube length (1). CONCLUSIONS: Patients with a history of scleritis have a low risk of scleritis recurrence or scleral perforation after glaucoma surgery but should be counseled appropriately on the higher risk of reoperation.
RESUMO
BACKGROUND/AIMS: To identify factors predictive of post-management secondary glaucoma in eyes with iris melanoma. METHODS: Patients with iris melanoma who were conservatively managed on the Ocular Oncology Service, Wills Eye Hospital from 1970 to 2016 were included. Charts were retrospectively reviewed, and binary logistic regression analysis was performed. Main outcome measures were factors predictive of post-management glaucoma, defined as intraocular pressure (IOP) > 22 mmHg following melanoma treatment. RESULTS: Of 271 patients with iris melanoma, melanoma-related glaucoma was identified in 40 (15%) at presentation and post-management glaucoma developed in 75 (28%) at a mean of 103.7 months (range:1.0-120.0). Comparison (post-management glaucoma vs. no glaucoma) revealed patients with post-management glaucoma presented with worse visual acuity (20/50-20/150) (17% vs. 5%, p = 0.001), increased mean tumour basal diameter (5.1 mm vs. 4.3 mm, p = 0.004), greater melanoma-related increased IOP on presentation (24.1 mmHg vs. 16.2 mmHg, p < 0.001), diffuse tumour shape (9% vs. 4%, p = 0.01), American Joint Committee on Cancer (AJCC) T4 category (7% vs. 2%, p = 0.03), and extraocular tumour extension (7% vs. 2%, p = 0.03). Risk factors for post-management glaucoma identified by multivariate analysis included melanoma-related increased IOP at presentation (OR:1.1, [1.08-1.22] per 1-mmHg increase, p < 0.001), increased mean tumour basal diameter (OR:1.17, [1.02-1.33] per 1-millimetre increments, p = 0.03), advanced AJCC clinical T subcategory (OR:1.23, [1.04-1.46] per 1-subcategory increments, p = 0.02) and plaque radiotherapy treatment (OR:2.32, [1.13-4.75], p = 0.02). CONCLUSION: Features of iris melanoma that predicted post-management glaucoma included melanoma-related increased IOP on presentation, advanced AJCC clinical T subcategory, increased mean tumour basal diameter, and plaque radiotherapy treatment.

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.

Purpose: The purpose of this study was to accurately forecast future reliable visual field (VF) mean deviation (MD) values by correcting for poor reliability. Methods: Four linear regression techniques (standard, unfiltered, corrected, and weighted) were fit to VF data from 5939 eyes with a final reliable VF. For each eye, all VFs, except the final one, were used to fit the models. Then, the difference between the final VF MD value and each model's estimate for the final VF MD value was used to calculate model error. We aggregated the error for each model across all eyes to compare model performance. The results were further broken down into eye-level reliability subgroups to track performance as reliability levels fluctuate. Results: The standard method, used in the Humphrey Field Analyzer (HFA), was the worst performing model with an average residual that was 0.69 dB higher than the average from the unfiltered method, and 0.79 dB higher than that of the weighted and corrected methods. The weighted method was the best performing model, beating the standard model by as much as 1.75 dB in the 40% to 50% eye-level reliability subgroup. However, its average 95% prediction interval was relatively large at 7.67 dB. Conclusions: Including all VFs in the trend estimation has more predictive power for future reliable VFs than excluding unreliable VFs. Correcting for VF reliability further improves model accuracy. Translational Relevance: The VF correction methods described in this paper may allow clinicians to catch VF worsening at an earlier stage.

PURPOSE: Clinicians use both global and point-wise information from visual fields to assess the rate of glaucomatous functional progression. We asked which objective, quantitative measures best correlated with subjective assessment by glaucoma experts. In particular, we aimed to determine how much that judgment was based on localized rates of change vs. on global indices reported by the perimeter. DESIGN: Prospective cohort study. PARTICIPANTS: Eleven academic, expert glaucoma specialists independently scored the rate of functional progression, from 1 (improvement) to 7 (very rapid progression), for a series of 5 biannual clinical printouts from 100 glaucoma or glaucoma suspect eyes of 51 participants, 20 of which were scored twice to assess repeatability. METHODS: Regression models were used to predict the average of the 11 clinicians' scores based on objective rates of change of mean deviation (MD), visual field index (VFI), pattern standard deviation (PSD), the Nth fastest progressing location, and the Nth fastest progressing of 10 anatomically defined clusters of locations after weighting by eccentricity. MAIN OUTCOME MEASURES: Correlation between the objective rates of change and the average of the 11 clinicians' scores. RESULTS: The average MD of the study eyes was -2.4 dB (range, -16.8 to +2.8 dB). The mean clinician score was highly repeatable, with an intraclass correlation coefficient of 0.95. It correlated better with the rate of change of VFI (pseudo-R2 = 0.73, 95% confidence interval [CI, 0.60-0.83]) than with MD (pseudo-R2 = 0.63, 95% CI [0.45-0.76]) or PSD (pseudo-R2 = 0.41, 95% CI [0.26-0.55]). Using point-wise information, the highest correlations were found with the fifth-fastest progressing location (pseudo-R2 = 0.71, 95% CI [0.56-0.80]) and the fastest-progressing cluster after eccentricity weighting (pseudo-R2 = 0.61, 95% CI [0.48-0.72]). Among 25 eyes with an average VFI of > 99%, the highest observed pseudo-R2 value was 0.34 (95% CI [0.16-0.61]) for PSD. CONCLUSIONS: Expert academic glaucoma specialists' assessment of the rate of change correlated best with VFI rates, except in eyes with a VFI near the ceiling of 100%. Sensitivities averaged within clusters of locations have been shown to detect change sooner, but the experts' opinions correlated more closely with global VFI. This could be because it is currently the only index for which the perimeter automatically provides a quantitative estimate of the rate of functional progression.

OBJECTIVE: To investigate visual acuity (VA) outcomes and OCT-based biomarkers of vision outcomes in eyes with glaucoma undergoing pars plana vitrectomy (PPV) for idiopathic epiretinal membrane (ERM). DESIGN: Retrospective, consecutive case-control series. A previously described ERM grading scale was utilized for OCT analysis. SUBJECTS: Eyes with glaucoma undergoing PPV for idiopathic ERM. INTERVENTION: PPV with membrane peel (MP) surgery. MAIN OUTCOME MEASURES: The primary outcome was VA at postoperative month 6. Outcomes were compared to a contemporary, matched control group of eyes without concurrent glaucoma undergoing PPV for idiopathic ERM. RESULTS: A total of 103 eyes from 103 patients with ERM and glaucoma were followed for a mean (± standard deviation) of 656 (± 421) days after PPV with MP surgery. Glaucoma was classified as open angle in 98 (95.1%) eyes and closed angle in 5 (4.9%) eyes. Visual acuity improved from 0.72 ± 0.48 (20/105) to 0.55 ± 0.51 (20/71) at 6 months and to 0.50 ± 0.56 (20/63) at final follow-up (P < 0.001 for both the time points). Eyes with preoperative inner microcystoid changes (n = 59; 57.3%) had significantly worse preoperative VA, postoperative VA at month 6, and final VA compared to eyes without inner microcystoid changes (P = 0.028, 0.004, and 0.007, respectively). Eyes were then compared to a matched control group of 139 eyes without glaucoma. Eyes with ERM and glaucoma had a higher rate of microcystic changes both before surgery (P < 0.001) and at postoperative month 6 (P < 0.001), and had a worse VA at 6 months (P = 0.03) and final follow-up (P = 0.04) compared to control eyes without glaucoma. Advanced disc cupping was the only factor independently correlated with worse 6-month (P = 0.01) and final (P = 0.007) VA in multivariate analysis. CONCLUSIONS: Preoperative inner microcystoid changes on OCT were present in over half of eyes with ERM and concurrent glaucoma, and may be a poor prognostic OCT biomarker. Eyes with ERM and concurrent glaucoma experienced worse vision outcomes compared to eyes with ERM alone, particularly those with advanced disc cupping.
