Importance

Underuse of eye care services leads to underdiagnosed and undertreated eye disease.

Objective

To assess the reasons for underuse of eye care and whether a novel, free eye disease screening program is engaging adults who are both at high risk of eye disease and were underusing eye care services.

Design, Setting, and Participants

In a population-based cross-sectional study, adult participants from the first year of the Michigan Screening and Intervention for Glaucoma and Eye Health Through Telemedicine (MI-SIGHT) Program were included. The participants were recruited from primary care clinics serving 2 low-income communities. Recruitment occurred between June 28, 2020 and June 27, 2021 at the free clinic, and between January 27, 2021 and January 26, 2022 at a federally qualified health clinic. Data were analyzed from December 7, 2022, to May 29, 2024. Participants received comprehensive eye disease screening and completed surveys assessing health and prior eye care use. Risk factors for eye disease included age 65 years and older, diabetes, personal or family history of eye disease, and self-identifying as Black or African American individuals who were aged 50 years or older. Underuse of eye care was defined as no eye examination in 2 or more years.

Main Outcomes and Measures

Percentage of participants who were at high risk of eye disease and underused eye care services before accessing this program.

Results

A total of 1171 MI-SIGHT participants were a mean (SD) age of 55 (14.5) years; 437 (38%) identified as male; 591 (54%) self-identified as Black or African American, 101 (10%) as Hispanic or Latino, and 371 (34%) as White; 492 (43%) had high school education or less, and 696 (70%) reported an annual household income of less than $30 000. Characteristics of participants reporting not having had an eye examination in 2 years or more included 23% (n = 151) of participants 65 years and over, 33% (n = 214) of participants who self-reported diabetes, 25% (n = 130) of participants reporting a family history of glaucoma, 3% (n = 14) of those with self-reported glaucoma; and 33% (n = 202) of Black or African-American participants aged 50 years and older. In participants who reported not having had an eye examination in 2 or more years, 21% (n = 137) screened positive for glaucoma, 20% (n = 129) for cataract, 6% (n = 38) for diabetic retinopathy, and 1% (n = 9) for age-related macular degeneration. Reported reasons for why participants had not had an eye examination included no insurance (175 of 627 [28%]), no reason to go (no problem) (135 of 627 [22%]), and cost of eye examination (101 of 627 [16%]).

Conclusions and Relevance

The findings of this study suggest that placing eye disease detection programs in primary care clinics in underserved areas may improve eye disease detection and treatment, possibly mitigating needless vision loss in the US.
