Brief Summary

The investigators are conducting a 5-year prospective, 2:1 cluster-randomized controlled trial, funded by the Centers for Disease Control (CDC), which provides vision screenings to underserved New York City residents living in affordable housing buildings in Harlem and Washington Heights.

Outcome Measures

Primary Outcomes (1)

  • Proportion of Subjects with Visual Acuity Worse than 20/40

    Visual acuity (VA) is a measure of the spatial resolution of the visual processing system. Visual acuity will be measured in each eye and measured as ≤20/40 or \>20/40. Since there are two best corrected distance visual acuity measurements per person (right eye and left eye), the visual acuity in the worse eye will be used in the analysis and reported at the patient level, rather than the eye level. Visual acuity analysis will be handled as a dichotomous variable and the proportion of subjects with visual acuity 20/40 or worse will be considered abnormal.

Study Arms (2)

Enhanced Intervention

ACTIVE COMPARATOR

Consented subjects living in buildings randomized to the Patient Navigator Intervention arm who failed the screening and needed vision correction received free eyeglasses, which were fitted by an optician at the housing building. If they were referred to an ophthalmologist for a follow-up eye exam, they received enhanced support with patient navigators to assist with follow-up eye exams at Columbia Ophthalmology or Harlem Hospital, specifically eye exam appointment scheduling and arranging transportation over a 1-year period.

Behavioral: Enhanced Intervention Using Patient Navigators

Usual Care

PLACEBO COMPARATOR

Consented subjects living in buildings randomized to Usual Care arm who failed the screening and needed vision correction were given an eyeglasses prescription and a list of optical shops within 1 mile from their home. These subjects who are referred to an ophthalmologist for a follow-up eye exam were only scheduled for their initial appointment at either Columbia Ophthalmology or Harlem Hospital. They did not receive enhanced support. Scheduling this initial appointment allowed tracking of adherence.

Other: Usual Care

Interventions

Enhanced support by patient navigators assisted with follow-up eye exam appointment scheduling and arranging transportation over a 1-year period.

Enhanced Intervention

Usual Care subjects who failed the screening and needed vision correction were given an eyeglasses prescription and a list of optical shops within 1 mile from their home. These subjects did not receive enhanced support. Scheduling this initial appointment will allow tracking of adherence.
