Criteria-Based Assessment of a Teleophthalmology Diabetic Retinopathy Evaluation Program in a Primary Care Setting.

Background:Studies have shown that teleophthalmology programs using a nonmydriatic camera in primary care settings can improve rates of diabetic retinopathy (DR) screening. However, such programs are not yet widespread due to common challenges in sustainability.Purpose:To comprehensively evaluate clinical and operational measures of an urban primary care clinic's 1-year pilot teleophthalmology DR evaluation program.Materials and Methods:This retrospective analysis used five metrics to evaluate the program: clinical diabetic retinal exam (DRE) rate, visual acuity and pathology, camera utilization, billing and insurance reimbursements, and outcomes of follow-up referrals.Results:Two hundred eleven patients were screened over 14 months. The DRE rate had more than doubled (34-75%). Of the patients, 55.9% had vision better than 20/50 in each eye and 21% with at least 1 eye worse than or equal to 20/70. DR was noted in 11% of patients. The program's first few months saw greatest camera use. Government and Medicare Advantage insurers were significantly (p < 0.001) less likely to reimburse than commercial insurers. Twenty-seven percent of patients screened had documented follow-up with an eye care provider within 16 months of their screening. Patients diagnosed with DR or recommended follow-up within 1 month were significantly (p < 0.001) more likely to schedule an appointment.Discussion:Challenges to program sustainability include efficient utilization, reimbursement from governmental insurers, and adherence to follow-up recommendations.Conclusions:Assessing teleophthalmology programs with the aforementioned five metrics allows for a comprehensive evaluation of impact and sustainability. This may be utilized to standardize the implementation and evaluation of such programs across diverse settings.

Nonadherence to Cardiovascular Drugs Predicts Risk for Non-Arthritic Anterior Ischemic Optic Neuropathy: A Large-Scale National Study.

Purpose: While patients with cardiovascular comorbidities are at a higher risk for the occurrence of non-arteritic anterior ischemic optic neuropathy (NAION), it is unclear whether adherence to medication results in risk reduction. The purpose of this study was to investigate whether nonadherence to medical therapy for cardiovascular morbidity correlates with a higher risk for NAION when compared to patients with strict adherence. Methods: A retrospective case-control study was conducted among members of Clalit Health Services in Israel from 2001 to 2022. For each of the 757 NAION cases, three controls (totaling 2271 patients) were matched based on birth year and sex, with a propensity score analysis employed to adjust for a range of comorbidities. A patient was deemed nonadherent with medical treatment if their purchased quantity of medication was less than 60% of the prescribed annual dosage. Mixed models were used to evaluate exposure differences, and conditional logistic regression was applied, incorporating adjustments for socioeconomic status and ethnicity, to examine the impact of medication nonadherence on NAION risk. Results: A total of 3028 patients were included in the study; 757 patients with the diagnosis of NAION and 2271 in the matched control group. The average age of NAION patients was 69 ± 9 years and 55% were male. After adjustments for socioeconomic status and ethnicity, nonadherence to calcium channel blockers (CCBs) (odds ratio [OR]: 1.33, 95% confidence interval [CI]: 1.03-1.71) and anti-arrhythmic (OR: 5.67, 95% CI: 1.89-21.2) medications emerged as significant risk factors. Similarly, nonadherence to cardioprotective medications (OR: 1.46, 95% CI: 1.23-1.74) was also identified as a significant risk factor. Conclusions: Nonadherence to treatments for cardiovascular disease, specifically to medications known to improve prognosis, is associated with a higher risk for NAION.

The Association between Gestational Age and Risk for Long Term Ophthalmic Morbidities among Offspring Delivered in Different Preterm Subgroups.

Objective: To investigate whether there is a linear association between the degree of prematurity and the risk for long-term ophthalmic morbidity among preterm infants. Study design: A population-based, retrospective cohort study, which included all singleton deliveries occurring between 1991 and 2014 at a single tertiary medical center. All infants were divided into four groups according to gestational age categories: extremely preterm births, very preterm births, moderate to late preterm births and term deliveries (reference group). Hospitalizations of offspring up to 18 years of age involving ophthalmic morbidity were evaluated. Survival curves compared cumulative hospitalizations and regression models controlled for confounding variables. Results: During the study period, 243,363 deliveries met the inclusion criteria. Ophthalmic-related hospitalization rates were lower among children born at term (0.9%) as compared with extremely preterm (3.6%), very preterm (2%), and moderate to late preterm (1.4%) born offspring (p < 0.01; using the chi-square test for trends). The survival curve demonstrated significantly different hospitalization rates between the gestational ages (p < 0.001). The regression demonstrated an independent risk for ophthalmic morbidity among extremely preterm born offspring (adjusted hazard ratio 3.8, confidence interval 1.6−9.2, p < 0.01), as well as very preterm and moderate to late preterm (adjusted hazard ratio 2.2 and 1.5, respectively) as compared with term deliveries. Conclusions: The risk for long-term ophthalmic-related hospitalization of preterm offspring gradually decreases as the gestational age increases.
