Précis: Of 611 individuals seen at referral clinic visits following community screenings, 76% were diagnosed with ≤1 eye condition needing treatment, generating a total of $213,110 in collections for the institution over 2.5 years. Purpose: The purpose of this study was to examine the outcomes and revenue generation of community-based eye screenings. Materials and Methods: Individuals aged 50 years and above screened at community sites in Baltimore, MD, with abnormal ophthalmic findings were referred for one free-of-charge definitive eye examination at the Wilmer Eye Institute. Diagnoses, treatment, and billing information were abstracted from electronic medical records of patients subsequently seen at Wilmer from January 1, 2016, to July 31, 2018. Results: A total of 611 individuals attended 3696 encounters at Wilmer during this time period. Most patients were female (60.3%) and African American (83.7%). At the screening event, 82.9% reported difficulty seeing when not wearing corrective eyewear, although only 49.8% reported having visited an eye doctor within the last 2 years. The majority (60.2%) reported having Medicare/Medicaid coverage, and 8.1% reported being uninsured. At the definitive eye examination after the screening, 75.5% of patients were diagnosed with ≥1 eye condition, most commonly cataract (30.3%), suspicion of glaucoma (24.9%), manifest glaucoma (11.9%), diabetic retinopathy (5.4%), and ocular hypertension (2.6%). Overall, 430 (70.4%) individuals required treatment including surgery (n=106), intravitreal injections (n=14), laser procedures (n=9), and medications (n=48). A total of $213,110 was collected for visits and procedures after the initial referral visit during the study period. Conclusions: A large community-based vision screening program in Baltimore was able to identify ocular conditions requiring treatment in underserved older adults and connect them to eyecare. Our findings also highlight that this model simultaneously generates new revenue streams for the institution organizing the community screenings.
