Factors Associated with Utilization of Teleretinal Imaging in a Hospital-Based Primary Care Setting.

Regular eye examinations to screen for the initial signs of diabetic retinopathy (DR) are crucial for preventing vision loss. Teleretinal imaging (TRI) offered in a primary care setting provides a means to improve adherence to DR screening, particularly for patients who face challenges in visiting eye care providers regularly. The present study evaluates the utilization of TRI to screen for DR in an outpatient, hospital-based primary care clinic. Patients with diabetes mellitus (DM) but without DR were eligible for point-of-care screening facilitated by their primary care provider, utilizing a non-mydriatic, handheld fundus camera. Patient demographics and clinical characteristics were extracted from the electronic medical record. Patients who underwent TRI were more likely to be male, non-White, and have up-to-date monitoring and treatment measures, including hemoglobin A1c (HbA1c), microalbumin, and low-density lipoprotein (LDL) levels, in accordance with Healthcare Effectiveness Data and Information Set (HEDIS) guidelines. Our findings demonstrate that TRI can reduce screening costs compared to a strategy where all patients are referred for in-person eye examinations. A net present value (NPV) analysis indicates that a screening site reaches the break-even point of operation within one year if an average of two patients are screened per workday.

Vision-Related Quality of Life and Seasonal Affective Disorder in Patients with Glaucoma and Macular Degeneration.

Seasonal affective disorder (SAD) is characterized by depressive episodes related to changes in the seasons. Patients with severe vision loss are at an increased risk of SAD. This study seeks to determine the extent to which patients with moderate vision loss report symptoms of SAD. In this cross-sectional, comparative case series, the Seasonal Pattern Assessment Questionnaire (SPAQ) and the National Eye Institute Visual Function Questionnaire (VFQ-39) were used to screen 111 patients with age-related macular degeneration (AMD) and/or primary open-angle glaucoma (POAG). A multiple regression analysis was performed to create a predictive model for SAD based on the Global Seasonality Score (GSS) using the VFQ-39. Subjects who reported symptoms of SAD (GSS > 8) had lower vision-related quality of life (composite score: 57.2 versus 73.2, p < 0.001). Exploratory factor analysis revealed that the items on the VFQ-39 split into two distinct dimensions that together accounted for 63.2% of the total variance in the GSS. One group of questions addressed vision-related problems; the other group comprised questions related to the quality of life. Whereas this model successfully identified patients with vision loss at risk of SAD, a model restricted to the questions available on the shorter, widely used VFQ-25 instrument did not reliably identify patients at risk of SAD.

Quality of referrals for glaucoma assessment: a cross-sectional survey of clinical data and outcomes.

PURPOSE: This study assessed the completeness of clinical information provided by ophthalmological and optometric referrals to glaucoma specialists consulting for open-angle glaucoma (OAG). METHODS: A retrospective, cross-sectional study of 72 internal referrals for evaluation of OAG in a multispecialty group practice was performed. The quality of the referral was assessed based on: (1) the completeness of the clinical triad of intraocular pressure measurement, visual field (VF), and cup-to-disk ratio for each eye; (2) the availability of the data necessary to calculate an ocular hypertension treatment study (OHTS) score; and (3) the presence of retinal nerve fiber layer (RNFL) imaging by mean of optical coherence tomography. RESULTS: The clinical triad was available in 57% of referrals, whereas an OHTS score was calculable in 24% of referrals (p < 0.001); RNLF imaging was available in 51% of referrals (p = 0.859). The completeness of clinical information was similar for ophthalmological and optometric referrals. From the date of referral to the time of the consultation, there was a significant increase in the availability of the clinical triad (57-65%; p = 0.013) and the OHTS score (24-5%; p = 0.004) but not for RNFL imaging (51-56%; p = 0.618). The most common missing clinical information was VF testing, which was absent in 42% of referrals. CONCLUSIONS: Key clinical data necessary for effective diagnosis and staging of OAG was lacking for many patients referred to glaucoma specialists.
