Abstract

Early detection and treatment of glaucoma can help prevent progression to irreversible blindness, yet in many countries the majority affected remain undiagnosed 1.With only one ophthalmologist per 556 000 population in Zambia as of 2022 2, the burden of early glaucoma detection falls on Allied Ophthalmic Personnel (AOP) working at the district and provincial health service level.This study aimed to evaluate the impact of a single day of focussed direct ophthalmoscopy training using a frugal solar-powered direct Fig. 1 Participant recruitment flow-chart.This diagram shows the enrolment and assignment of participants to the intervention (training and provision of Arclight ophthalmoscopes) and control (routing practice) groups from baseline to final follow-up at one month.
