Summary
This study screened underserved adults for eye conditions, finding that glaucoma, high intraocular pressure (IOP), and vision impairment significantly increased the likelihood of referral to ophthalmology.
Area of Science:
- Ophthalmology
- Public Health
- Community Health
Background:
- Underserved populations often lack access to regular eye care.
- Early detection of ocular pathology is crucial for preventing vision loss.
- The Manhattan Vision Screening and Follow-up Study addresses these gaps in Upper Manhattan.
Purpose of the Study:
- To provide eye care access to underserved populations.
- To determine the prevalence of ocular pathology.
- To identify risk factors for referral to ophthalmology.
Main Methods:
- Screened 708 adults aged 40+ in public housing.
- Referral criteria included visual acuity ≤20/40, intraocular pressure (IOP) ≥23 mmHg, or unreadable fundus images.
- Optometric exams determined the need for ophthalmology referral.
Main Results:
- 468 participants (66%) were referred to ophthalmology.
- Referred individuals were older, predominantly female, African American, and Hispanic.
- Risk factors for referral included pre-existing glaucoma (OR 3.14), IOP ≥23 mmHg (OR 5.04), and mild vision impairment (OR 2.51).
Conclusions:
- Community-based screening effectively identified ocular pathology in a high-risk population.
- The study facilitated access to essential eye care for underserved residents.
- Findings highlight the need for targeted interventions for vision health in vulnerable communities.
