Abstract
PURPOSE: Globally, there are few examples of repeated eye health surveys to assess changes in prevalence and causes of visual impairment, and service coverage over time. Two separate, unlinked rapid assessments of avoidable blindness (RAAB) were conducted in Nampula province, Mozambique in 2011 and 2018. This paper reports the observed changes and examines how the trends differ for males and females. METHODS: Standard RAAB methodology was used in both studies. Two-stage cluster sampling was used to generate random samples of adults aged over 50 years. Participants underwent a simplified visual acuity (VA) exam, a lens exam and posterior segment exam using a direct ophthalmoscope for all subjects with presenting VA<6/18. Data were analysed using Stata and logistic regression models were developed to assess changes. RESULTS: = .028). Cataract surgical coverage was higher among males in both surveys (13.4% among males vs 7.7% among females in 2011, and 40.0% among males vs 19.4% among females in 2018) and the gender disparity grew between surveys. CONCLUSION: Significant changes were observed in the eye health and service coverage between 2011 and 2018. Further improvements to services are required to improve access for women and people with moderate visual impairment.
