Manhattan Vision Screening and Follow-Up Study (NYC-SIGHT)

October 10, 2025 updated by: Lisa Hark, PhD, MBA, Columbia University

The Manhattan Vision Screening and Follow-Up Study (NYC-SIGHT)

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.

Detailed Description

This study aims to increase engagement, detection and management of glaucoma, vision impairment, cataracts, and other eye diseases in vulnerable populations living in New York City. This study considers disparities by race, ethnicity, gender, geography, and socioeconomic status using innovative approaches such as patient navigators. Individuals over the age of 40 living in New York City Housing Authority (NYCHA) Housing buildings are eligible.

Design Details

  • Primary Purpose: Screening
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Enhanced Intervention
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
Enhanced support by patient navigators assisted with follow-up eye exam appointment scheduling and arranging transportation over a 1-year period.
Placebo Comparator: Usual Care
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
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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Proportion of Subjects with Visual Acuity Worse than 20/40
Time Frame: 2 years
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.
