Summary of Research Results: Adam VanDeusen and Denise St. Jean

Unite For Sight Global Impact Fellow volunteers frequently pursue public health research studies in Unite For Sight's Global Impact Lab program. The research topics are developed by Unite For Sight and the partner eye clinics, the research studies are approved by an Institutional Review Board (IRB), and the research findings are submitted to the eye clinic partners for program development.

Adam VanDeusen and Denise St. Jean, "Blindness and Poverty: A Paired-Cohort Study Assessing the Relationship Between Poverty and Visual Impairment from Cataract in Ghana"

This study contains two main components: a cross-sectional analysis and a longitudinal analysis. The cross-sectional component assesses the relationship between cataract and poverty by comparing the economic well-being of patients with cataracts to the economic well-being of patients without cataracts when they first attend a Unite For Sight outreach event.

The longitudinal component measures the ways in which the economic wellbeing of these patients changes over time. This analysis includes three patient groups: 1) those who did not present with cataracts, 2) those who presented with cataracts and received surgery, and 3) those who presented with cataracts but did not receive surgery. This technique allows for controlled measurement of the economic impact of correcting cataract.

188 patients were interviewed for the first time during the second year of the study. 28 of these patients were removed due to missing or low-quality data, leaving a sample size of 160. The sample was 46.9% male and 53.1% female, and the mean age was 63.1 years.
