RESUMEN
PURPOSE: To review the current published literature for high-quality studies on the use of selective laser trabeculoplasty (SLT) for the treatment of glaucoma. This is an update of the Ophthalmic Technology Assessment titled, "Laser Trabeculoplasty for Open-Angle Glaucoma," published in November 2011. METHODS: Literature searches in the PubMed database in March 2020, September 2021, August 2022, and March 2023 yielded 110 articles. The abstracts of these articles were examined to include those written since November 2011 and to exclude reviews and non-English articles. The panel reviewed 47 articles in full text, and 30 were found to fit the inclusion criteria. The panel methodologist assigned a level I rating to 19 studies and a level II rating to 11 studies. RESULTS: Data in the level I studies support the long-term effectiveness of SLT as primary treatment or as a supplemental therapy to glaucoma medications for patients with open-angle glaucoma. Several level I studies also found that SLT and argon laser trabeculoplasty (ALT) are equivalent in terms of safety and long-term efficacy. Level I evidence indicates that perioperative corticosteroid and nonsteroidal anti-inflammatory drug eye drops do not hinder the intraocular pressure (IOP)-lowering effect of SLT treatment. The impact of these eye drops on lowering IOP differed in various studies. No level I or II studies exist that determine the ideal power settings for SLT. CONCLUSIONS: Based on level I evidence, SLT is an effective long-term option for the treatment of open-angle glaucoma and is equivalent to ALT. It can be used as either a primary intervention, a replacement for medication, or an additional therapy with glaucoma medications.

PURPOSE: To evaluate the recently published literature on the efficacy and safety of the use of aqueous shunts with extraocular reservoir for the management of adult open-angle glaucomas (OAGs). METHODS: A search of peer-reviewed literature was last conducted in April 2023 of the PubMed database and included only articles published since the last aqueous shunt Ophthalmic Technology Assessment, which assessed articles published before 2008. The abstracts of these 419 articles were examined, and 58 studies were selected for full-text analysis. After inclusion and exclusion criteria were applied, 28 articles were selected and assigned ratings by the panel methodologist according to the level of evidence. Twenty-five articles were rated level I and 3 articles were rated level II. There were no level III articles. RESULTS: Implantation of aqueous shunts with extraocular reservoir can lower intraocular pressure (IOP) by between one-third and one-half of baseline IOP, depending on whether it is undertaken as the primary or secondary glaucoma surgery. Success rates for aqueous shunts were found to be better than for trabeculectomies in eyes with prior incisional surgery. Conversely, in eyes without prior incisional surgery, implantation of aqueous shunts was found to have an overall lower success rate as the primary glaucoma procedure compared with trabeculectomy. Although both valved and nonvalved aqueous shunts with extraocular reservoir were effective, the nonvalved device generally achieved slightly lower long-term IOPs with fewer glaucoma medications and less need for additional glaucoma surgery. Both devices slow the rates of visual field progression with efficacy comparable with that of trabeculectomy. Early aqueous humor suppression after aqueous shunt implantation is recommended for the management of the postoperative hypertensive phase and long-term IOP control. No strong evidence supports the routine use of mitomycin C with aqueous shunt implantation for OAG. CONCLUSIONS: Implantation of aqueous shunts with extraocular reservoir, including valved or nonvalved devices, has been shown to be an effective strategy to lower IOP. Strong level I evidence supports the use of aqueous shunts with extraocular reservoir by clinicians for the management of adult OAG.

PURPOSE: To determine the intraocular pressure (IOP) reduction of various trabecular procedures (a form of minimally invasive glaucoma surgery [MIGS]) combined with cataract surgery compared with cataract surgery alone, to compare the safety of the various trabecular procedures, and to highlight patient characteristics that may favor one trabecular procedure over another. METHODS: A search of English-language peer-reviewed literature in the PubMed database was initially conducted in February 2021 and updated in April 2023. This yielded 279 articles. Twenty studies met initial inclusion and exclusion criteria and were assessed for quality by the panel methodologist. Of these, 10 were rated level I, 3 were rated level II, and 7 were rated level III. Only the 10 level I randomized controlled trials (RCTs) were included in this assessment, and all were subject to potential industry-sponsorship bias. RESULTS: The current analysis focuses on the amount of IOP reduction (in studies that involved medication washout) and on IOP reduction with concurrent medication reduction (in studies that did not involve medication washout). Based on studies that performed a medication washout, adding a trabecular procedure to cataract surgery provided an additional 1.6 to 2.3 mmHg IOP reduction in subjects with hypertensive, mild to moderate open-angle glaucoma (OAG) at 2 years over cataract surgery alone, which itself provided approximately 5.4 to 7.6 mmHg IOP reduction. In other words, adding a trabecular procedure provided an additional 3.8% to 8.9% IOP reduction over cataract surgery alone, which itself provided 21% to 28% IOP reduction. There was no clear benefit of one trabecular procedure over another. Patient-specific considerations that can guide procedure selection include uveitis predisposition, bleeding risk, metal allergy, and narrowing of Schlemm's canal. There are no level I data on the efficacy of trabecular procedures in subjects with pretreatment IOP of 21 mmHg or less. CONCLUSIONS: Trabecular procedures combined with cataract surgery provide an additional mild IOP reduction over cataract surgery alone in hypertensive OAG subjects. Additional research should standardize outcome definitions, avoid industry sponsorship bias, and study the efficacy of these procedures in normotensive OAG.

PURPOSE: To evaluate the current published literature on the utility of the 10-2 visual field (VF) testing strategy for the evaluation and management of early glaucoma, defined here as mean deviation (MD) better than -6 decibels (dB). METHODS: A search of the peer-reviewed literature was last conducted in June 2023 in the PubMed database. Abstracts of 986 articles were examined to exclude reviews and non-English-language articles. After inclusion and exclusion criteria were applied, 26 articles were selected, and the panel methodologist rated them for strength of evidence. Thirteen articles were rated level I, and 8 articles were rated level II. The 5 level III articles were excluded. Data from the 21 included articles were abstracted and reviewed. RESULTS: The central 12 locations on the 24-2 VF test grid lie within the central 10 degrees covered by the 10-2 VF test. In early glaucoma, defects detected within the central 10 degrees generally agree between the 2 tests. Defects within the central 10 degrees of the 24-2 VF test can predict defects on the 10-2 VF test, although the 24-2 may miss defects detected on the 10-2 VF test. In addition, results from the 10-2 VF test show better association with findings from OCT scans of the macular ganglion cell complex. Modifications of the 24-2 test that include extra test locations within the central 10 degrees improve detection of central defects found on 10-2 VF testing. CONCLUSIONS: Evidence to date does not support routine testing using 10-2 VF for patients with early glaucoma. However, early 10-2 VF testing may provide sufficient additional information for some patients, particularly those with a repeatable defect within the central 12 locations of the standard 24-2 VF test or who have inner retinal layer thinning on OCT scans of the macula.

PURPOSE: To review the current published literature on the utility of corneal hysteresis (CH) to assist the clinician in the diagnosis of glaucoma or in the assessment of risk for disease progression in existing glaucoma patients. METHODS: Searches of the peer-reviewed literature in the PubMed database were performed through July 2022. The abstracts of 423 identified articles were examined to exclude reviews and non-English articles. After inclusion and exclusion criteria were applied, 19 articles were selected, and the panel methodologist rated them for level of evidence. Eight articles were rated level I, and 5 articles were rated level II. The 6 articles rated level III were excluded. RESULTS: Corneal hysteresis is lower in patients with primary open-angle glaucoma, primary angle-closure glaucoma, pseudoexfoliative glaucoma, and pseudoexfoliation syndrome compared with normal subjects. Interpretation of low CH in patients with high intraocular pressure (IOP) or on topical hypotensive medications is complicated by the influence of these parameters on CH measurements. However, CH is also lower in treatment-naïve, normal-tension glaucoma patients compared with normal subjects who have a similar IOP. In addition, lower CH is associated with an increased risk of progression of glaucoma based on visual fields or structural markers in open-angle glaucoma patients, including those with apparently well-controlled IOP. CONCLUSIONS: Corneal hysteresis is lower in glaucoma patients compared with normal subjects, and lower CH is associated with an increased risk of disease progression. However, a causal relationship remains to be demonstrated. Nevertheless, measurement of CH complements current structural and functional assessments in determining disease risk in glaucoma suspects and patients.

INTRODUCTION: We conducted a secondary, real-world clinical assessment of a randomized controlled trial to determine how a glaucoma medication adherence intervention impacted the clinical outcomes of participants at 12 months post-randomization. Participants included veterans at a VA eye clinic with medically treated glaucoma who reported poor adherence and their companions, if applicable. METHODS: The treatment group received a glaucoma education session with drop administration instruction and virtual reminders from a "smart bottle" (AdhereTech) for their eye drops. The control group received a general eye health class and the smart bottle with the reminder function turned off. Medical chart extraction determined if participants in each group experienced visual field progression, additional glaucoma medications, or a recommendation for surgery or laser due to inadequate intraocular pressure control over the 12 months following randomization. The main outcome measure was disease progression, defined as visual field progression or escalation of glaucoma therapy, in the 12 months following randomization. RESULTS: Thirty-six versus 32% of the intervention (n = 100) versus control (n = 100) groups, respectively, experienced disease intensification. There was no difference between the intervention and control groups in terms of intensification (intervention vs. control group odds ratio: 1.20; 95% confidence interval: [0.67, 2.15]), including when age, race, and disease severity were accounted for in the logistic regression model. Those whose study dates included time during the COVID-19 pandemic were evenly distributed between groups. CONCLUSIONS: A multifaceted intervention that improved medication adherence for glaucoma for 6 months did not affect the clinical outcomes measured at 12 months post-randomization. Twelve months may not be long enough to see the clinical effect of this intervention or more than 6 months of intervention are needed.

PURPOSE: To review the current published literature on the use of OCT angiography (OCTA) to help detect changes associated with the diagnosis of primary open-angle glaucoma. METHODS: Searches of the peer-reviewed literature were conducted in March 2018, June 2018, April 2019, December 2019, and June 2020 in the PubMed and Cochrane Library databases. Abstracts of 459 articles were examined to exclude reviews and non-English articles. After inclusion and exclusion criteria were applied, 75 articles were selected and the panel methodologist rated them for strength of evidence. Three articles were rated level I and 57 articles were rated level II. The 15 level III articles were excluded. RESULTS: OCT angiography can detect decreased capillary vessel density within the peripapillary nerve fiber layer (level II) and macula (level I and II) in patients with suspected glaucoma, preperimetric glaucoma, and perimetric glaucoma. The degree of vessel density loss correlates significantly with glaucoma severity both overall and topographically (level II) as well as longitudinally (level I). For differentiating glaucomatous from healthy eyes, some studies found that peripapillary and macular vessel density measurements by OCTA show a diagnostic ability (area under the receiver operating characteristic curve) that is comparable with structural OCT retinal nerve fiber and ganglion cell thickness measurements, whereas other studies found that structural OCT measurements perform better. Choroidal or deep-layer microvasculature dropout as measured by OCTA is also associated with glaucoma damage (level I and II). Lower peripapillary and macular vessel density and choroidal microvasculature dropout are associated with faster rates of disease progression (level I and II). CONCLUSIONS: Vessel density loss associated with glaucoma can be detected by OCTA. Peripapillary, macular, and choroidal vessel density parameters may complement visual field and structural OCT measurements in the diagnosis of glaucoma.

BACKGROUND: Glaucoma treatment requires patients to follow daily, often times complex, eye drop regimens, but adherence is poor for many patients, putting them at risk for irreversible vision loss. A comprehensive approach is needed to address the challenges in the self-management of glaucoma. The purpose of this study is to improve glaucoma medication adherence in Veterans with medically treated glaucoma using an education-based intervention. METHODS/DESIGN: This study is a single-site randomized controlled trial enrolling 200 Veterans and their companions, if companions are involved in their care. It has two arms: an intervention group and a control group. Participants in the intervention group receive an educational session with a non-physician interventionist and are provided with an AdhereTech smart bottle with the reminder functions activated. The control group is designed as an attention control such that they have a session on general eye health and are provided with a smart bottle but without the reminder functions activated. The primary outcome is the proportion of prescribed doses taken on schedule over 6 months following randomization according to the smart bottle. Secondary outcomes include intensification of glaucoma treatment, cost of intervention delivery, and cost-effectiveness of the intervention over 12 months. DISCUSSION: The education-based intervention that we are testing is comprehensive in scope, to encompass a variety of barriers to adherence that glaucoma patients encounter, but personalized to address issues facing individual patients. Particular attention was given to feasibility in the real-world setting, as the high throughput of patients and lack of reimbursement for educational encounters in ophthalmology would limit implementation of a resource-intensive intervention.

OBJECTIVES: Health systems are adopting electronic health records (EHRs). There are few studies on the effects of EHR implementation on graduate medical education. The authors sought to longitudinally assess perceptions of the impact of EHRs on graduate medical education during implementation and 2 years after implementation. METHODS: A survey was distributed to faculty and trainees during the first year (2013) of adoption of the EHR system. A follow-up survey was distributed 2 years later (2015). The χ2 test was used to compare the quantitative responses, and factor analysis was conducted to identify correlations between items. Free text responses were analyzed qualitatively. RESULTS: The initial survey (in 2013) included 290 faculty and 106 trainees; the follow-up survey (in 2015) included 353 faculty and 226 trainees. In 2013, respondents had a positive impression of EHRs. During the implementation phase, participants believed that face-to-face teaching was negatively affected (P = 0.001). Faculty believed EHRs had a negative effect on trainees' ability to take a history/conduct physical examinations (P = 0.002) and to formulate a differential diagnosis/plan independently (P = 0.003). In 2015, faculty opinions of the impact of the EHR remained unchanged; trainee responses were more positive than in 2013 in some areas. Qualitative analysis showed that the most frequent strategies to enhance the educational process were the development of EHR skills and improved chart access and note assistance. CONCLUSIONS: Respondents remain positive about the EHR 2 years after implementation. Faculty remain concerned about its effect on the educational process, whereas residents appear more positive regarding the potential for EHRs to enhance their education.

BACKGROUND: Patient education materials should be written at a level that is understandable for patients with low health literacy. The aims of this study are (1) to review the literature on readability of ophthalmic patient education materials and (2) to evaluate and revise our institution's patient education materials about glaucoma using evidence-based guidelines on writing for patients with low health literacy. METHODS: A systematic search was conducted on the PubMed/MEDLINE database for studies that have evaluated readability level of ophthalmic patient education materials, and the reported readability scores were assessed. Additionally, we collected evidence-based guidelines for writing easy-to-read patient education materials, and these recommendations were applied to revise 12 patient education handouts on various glaucoma topics at our institution. Readability measures, including Flesch-Kincaid Grade Level (FKGL), and word count were calculated for the original and revised documents. The original and revised versions of the handouts were then scored in random order by two glaucoma specialists using the Suitability Assessment of Materials (SAM) instrument, a grading scale used to evaluate suitability of health information materials for patients. Paired t test was used to analyze changes in readability measures, word count, and SAM score between original and revised handouts. Finally, five glaucoma patients were interviewed to discuss the revised materials, and patient feedback was analyzed qualitatively. RESULTS: Our literature search included 13 studies that evaluated a total of 950 educational materials. Among the mean FKGL readability scores reported in these studies, the median was 11 (representing an eleventh-grade reading level). At our institution, handouts' readability averaged a tenth-grade reading level (FKGL = 10.0 ± 1.6), but revising the handouts improved their readability to a sixth-grade reading level (FKGL = 6.4 ± 1.2) (p < 0.001). Additionally, the mean SAM score of our institution's handouts improved from 60 ± 7 % (adequate) for the original versions to 88 ± 4 % (superior) for the revised handouts (p < 0.001). CONCLUSIONS: Our systematic review of the literature reveals that ophthalmic patient education materials are consistently written at a level that is too high for many patients to understand. Our institution's experience suggests that applying guidelines on writing easy-to-understand material can improve the readability and suitability of educational materials for patients with low health literacy.

BACKGROUND: Glaucoma is an important cause of irreversible blindness. This study describes the characteristics of a large, diverse group of glaucoma patients and evaluates associations between demographic and clinical characteristics and blindness. METHODS: Data were gathered via retrospective chart review of patients (N = 1,454) who were seen between July 2007 and July 2010 by glaucoma service providers at Duke Eye Center. Visual acuity and visual field criteria were used to determine whether patients met the criteria for legal blindness. Descriptive and comparative statistical analyses were performed on the glaucoma patients who were not blind (n = 1,258) and those who were blind (n = 196). A subgroup analysis of only those patients with primary open-angle glaucoma was also performed. RESULTS: In this tertiary care population, 13% (n = 196) of glaucoma patients met criteria for legal blindness, nearly one-half of whom (n = 94) were blind from glaucoma, and another one-third of whom (n = 69) had glaucoma-related blindness. The most common glaucoma diagnosis at all levels of vision was primary open-angle glaucoma. A larger proportion of black patients compared with white patients demonstrated vision loss; the odds ratio (OR) for blindness was 2.25 (95% CI, 1.6-3.2) for black patients compared with white patients. The use of systemic antihypertensive medications was higher among patients who were blind compared with patients who were not blind (OR = 2.1; 95% CI, 1.4-3.1). A subgroup analysis including only patients with primary open-angle glaucoma showed similar results for both black race and use of systemic antihypertensive medications. The relationship between use of systemic antihypertensive medications and blindness was not different between black patients and white patients (interaction P = .268). LIMITATIONS: Data were based on chart review, and associations may be confounded by unmeasured factors. CONCLUSIONS: Treated systemic hypertension may be correlated with blindness, and the cause cannot be explained solely by race. In addition, this study demonstrated that there is continued disparity between black patients and white patients with regards to blindness from glaucoma.

PURPOSE: The utility of screening for early diagnosis of glaucoma remains a widely debated topic in the care of ophthalmic patients. There are currently no population-based guidelines regarding screening for glaucoma. The purpose of this study is to determine the utility of optical coherence tomography (OCT) for early glaucoma screening in a population of diabetic patients. The results of this study may inform future screening practices. METHODS: The current study is a post hoc analysis of OCT data collected from diabetic patients screened for eye disease over 6 months. Glaucoma suspects (GS) were identified based on abnormal retinal nerve fiber layer (RNFL) thickness on OCT. Fundus photographs of GS were graded by two independent raters for vertical cup-to-disc ratio (CDR) and other signs of glaucomatous changes. RESULTS: Of the 807 subjects screened, 50 patients (6.2%) were identified as GS. The mean RNFL thickness for GS was significantly lower than the mean RNFL in the total screening population (p < .001). Median CDR for GS was 0.44. Twenty-eight eyes of 17 GS were marked as having optic disc notching or rim thinning by at least one grader. Cohen's kappa statistic for inter-rater reliability was 0.85. Racial differences showed that mean CDR was significantly higher in non-whites (p < .001). Older age was associated with thinner RNFL (r = -0.29, p = .004). CONCLUSIONS: Results of this study suggest that in a sample of diabetic patients, a small but clinically significant minority may be flagged as GS based on OCT. Nearly one-third of GS eyes were found to have glaucomatous changes on fundus photography by at least one grader. These results suggest screening with OCT may be useful in detecting early glaucomatous changes in high-risk populations, particularly older, non-white patients with diabetes.

Purpose: To assess the severity, progression, and treatment burden of diabetic retinopathy (DR) in patients after bariatric surgery compared with controls. Methods: A retrospective cohort study was performed of patients with type 2 diabetes and DR seen at the Duke Eye Center between 2014 and 2023. Clinical data included hemoglobin A1c (HbA1c), diagnostic stage of DR, diabetic macular edema (DME) or vitreous hemorrhage (VH), visual acuity (VA), and treatment burden at baseline and follow-up. Generalized estimating equation analysis was used to account for the correlation between 2 eyes of the same patient. Results: Sixteen patients who had bariatric surgery were matched by age, sex, and duration of diabetes with 60 control patients managed medically during the same time period. The HbA1c level, severity of DR, presence of DME or VH, VA, and treatment burden were not significantly different (all P > .05) at the baseline examination. On average, patients were followed for 6 years. The HbA1c level at the follow-up was significantly lower in the bariatric surgery group (6.4% vs 8.5%; P < .001). At the follow-up, the treatment burden was reduced in the bariatric surgery group compared with the control group (P = .04). There was a clear trend toward reduced progression of DR and treatment burden in the bariatric surgery group over the follow-up. Conclusions: Bariatric surgery may improve glycemic control, stabilize DR progression, and reduce the treatment burden, which may have a significant impact on quality of life for patients with DR.
RESUMEN
PURPOSE: To assess the incidence, risk factors, and clinical consequences of loss to follow up (LTFU) among glaucoma patients at our institution over a 10-year period. METHODS: This retrospective study examined LTFU among a cohort of glaucoma patients with a clinical encounter in 2010. LTFU was defined as 52 weeks or more without an encounter and without alternative reason for discontinued care, such as discharge, documented move, or death. Baseline demographic and clinical characteristics were collected and compared between LTFU and non-LTFU groups using a logistic regression model to identify risk factors for LTFU. Odds ratios (ORs) are reported with 95% confidence intervals. Clinical outcomes were documented for LTFU patients who returned after a lapse in care. RESULTS: Among the 395 included patients, 132 (33%) were LTFU over the 10-year study period. Characteristics associated with LTFU in a logistic regression model included greater disease severity (OR = 1.03 [1.01-1.05], p = .023, for each worsening decibel of mean deviation) and in-state rather than out-of-state residence (OR = 2.76 [1.12-6.80], p = .027). Other potential risk factors that did not reach significance included male gender (OR = 1.39 [0.92-2.13], p = .124), Black race (OR = 1.40 [0.91-2.16] p = .123), and legal blindness (OR = 1.58 [0.91-2.76] p = .107). Among the 132 patients who were LTFU, only 23 (17%) later returned to care, two-thirds (15/23) of whom returned with disease progression or complication. CONCLUSION: One-third of glaucoma patients became LTFU over a 10-year period, and LTFU may be associated with poor clinical outcomes. More research is needed to understand reasons for LTFU and to promote regular glaucoma care.

PURPOSE: To assess the relationship between glaucoma knowledge and disease severity. DESIGN: Substudy of a randomized controlled trial at a single Veterans Affairs (VA) eye clinic. PARTICIPANTS: Veterans with medically treated open-angle glaucoma who self-reported poor medication adherence. METHODS: Participants completed a glaucoma knowledge assessment using the 10-question National Eye Health Education Program (NEHEP) Eye-Q Test on glaucoma knowledge. Disease severity was determined using visual field criteria. Multiple linear regression was used to assess the association of NEHEP Eye-Q score and disease severity, adjusting for age, number of glaucoma medications, race, sex, and VA Care Assessment Needs (CAN) score. MAIN OUTCOME MEASURES: In this cross-sectional, preintervention analysis, the main outcome was glaucoma knowledge as measured by the NEHEP Eye-Q Test. RESULTS: Among the 200 study participants, glaucoma severity was mild in 53 (27%), moderate in 56 (28%), severe in 74 (37%), and indeterminant in 17 (9%). The NEHEP Eye-Q scores were low across all severity levels. Scored out of 10, the mean (standard deviation) NEHEP Eye-Q scores were 6.06 (1.57) for mild, 6.21 (1.47) for moderate, 6.28 (1.82) for severe, and 5.88 (1.93) for indeterminate stage. There was no evidence of a significant association between NEHEP scores and disease severity categories (P = 0.78). A regression model did not identify a significant estimated association between NEHEP Eye-Q scores and disease severity after adjusting for age, CAN risk score, number of glaucoma medications, race, and sex. CONCLUSIONS: There was no difference in level of glaucoma knowledge based on disease severity. Education-based interventions may benefit patients across all glaucoma stages.

Minimally invasive glaucoma surgeries (MIGS) and non-penetrating glaucoma procedures have changed the surgical management of glaucoma in recent years and are being explored in the management of uveitic glaucoma. Deep sclerectomy, Xen45 gel stent, gonioscopy-assisted transluminal trabeculotomy (GATT), trabectome, and canaloplasty are described in the literature as alternative surgeries that may work for uveitic glaucoma. While most of the published studies are retrospective case series, the results suggest success even in refractory cases and with less inflammation than more traditional surgeries.

Background The coronavirus disease 2019 (COVID-19) pandemic was a disruption for all aspects of medical education, especially for clinical students preparing for residency applications. Clinical rotations are essential for a student's specialty choice, especially for subspecialties such as ophthalmology where students may not get significant exposure during preclinical years. The cancellation of home and visiting ophthalmology electives due to the pandemic brought a need for newer, innovative ideas of instruction. Methods A 4-week not-for-credit virtual elective was developed at the Department of Ophthalmology for visiting medical students and was offered from August to October 2020. Visiting fourth-year medical students were paired with faculty and resident mentors for one-on-one virtual mentoring, in addition to participation in departmental conferences and research opportunities. Surveys were distributed to students and mentors, and results were analyzed using Microsoft Excel and GraphPad Prism 9. Results A total of 12 visiting fourth-year medical students participated in the virtual elective, 67% of whom did not have a home ophthalmology program. There was a significant increase in students' perception of their ophthalmology knowledge, with all of students reporting that the elective contributed to this. Students (100%) were "very satisfied" with their faculty mentors on a five-point Likert scale, with high satisfaction from faculty and resident mentors toward students also. The two required events in the elective, the journal club and case virtual conferences, were highly rated from students and mentors. Conclusion The virtual ophthalmology elective, which was developed to address medical education gaps due to the COVID-19 pandemic, was favorably viewed by all who participated. As dedicated ophthalmology instruction time has decreased over the years, it may become increasingly more important to turn to virtual resources for ophthalmology instruction and mentorship.
RESUMEN
PURPOSE: To provide a comprehensive assessment of the strategies studied to date that focus on improving glaucoma medication adherence. METHODS: A systematic review of the literature was conducted in MEDLINE (PubMed), Embase (Elsevier), and Scopus (Elsevier) from inception to March 1, 2021, of publications describing a device or strategy used to improve glaucoma medication adherence. RESULTS: 42 studies described by 50 papers were included. Five categories were identified: reminder systems, medication simplifications, behavioral change programs, education, and alternative engagement strategies. CONCLUSION: Most studies (40 of the 42) addressed the question of improved adherence directly, with 26 finding improved adherence. Notably, 14 examined the clinical effects of the intervention, either in terms of intraocular pressure (IOP) or visual fields. Only three found an improvement in IOP. None demonstrated a between group difference in visual field progression.

PURPOSE: To assess the within-trial cost-effectiveness of a behavioral intervention to improve glaucoma medication adherence. DESIGN: Prospective cost-effectiveness analysis of randomized, controlled trial data. METHODS: The study setting was a Veterans Affairs (VA) eye clinic. The patient population comprised veterans with medically treated glaucoma and self-reported poor adherence. Participants were randomized to a personalized educational session with a reminder bottle to promote medication adherence or to a control session on general eye health. Costs were assessed from the perspective of the VA payor at 6 months using the VA Managerial Cost Accounting System. Probabilistic sensitivity analyses were conducted using bootstrapped samples. The main outcome measures were the proportion of participants attaining ≥80% adherence as measured by electronic monitor, total intervention and medical resource costs, and incremental cost-effectiveness ratios comparing intervention to control at 6 months. RESULTS: Of 200 randomized participants, 95 of 100 assigned to the intervention and 97 of 100 assigned to the control had adherence outcomes at 6 months, and the proportion of adherent patients was higher in the intervention group compared to control (0.78 vs 0.40, P < .0001). All participants had costs at 6 months. The total cost at 6 months was $1,149,600 in the intervention group (n = 100) compared to $1,298,700 in the control group (n = 100). Thus, in a hypothetical cohort of 100 patients, the intervention was associated with cost savings (-$149,100) and resulted in 38 additional patients achieving medication adherence. CONCLUSIONS: An adherence-enhancing behavioral intervention was effective and cost saving at 6 months.
