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.

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.

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

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.
