Community eye health screenings led by optometrists identify significant glaucoma risk in high-risk population
Community-based eye health screenings, which include fundus photography and optometric exams, are effective at identifying individuals in high-risk populations who require further evaluation for glaucoma, according to a study.
The study, conducted as part of the Manhattan Vision Screening and Follow-up Study (NYC-SIGHT), highlighted the effectiveness of community-based eye health screenings in identifying individuals at high risk for glaucoma. The 5-year trial, which targeted residents of affordable housing developments and senior centers in New York City, successfully identified a significant number of individuals in need of further in-office glaucoma evaluations.
Of the 708 participants screened, 189 (26.6%) were referred for a more thorough glaucoma examination due to abnormal optic disc images or optometric exam results. The majority of those referred were older adults, with an average age of 68.5 years, and predominantly female (60%), Black (57%), and Hispanic (37%). Key factors influencing the likelihood of referral included self-reported glaucoma, elevated intraocular pressure (IOP > 23 mmHg), and the use of prescription eyeglasses.
The findings, which emphasize the importance of accessible eye health services for underserved communities, found that over half of the referred individuals attended follow-up evaluations. Among those, 34% were diagnosed with glaucoma, while 36% were classified as glaucoma suspects.
