Article Synopsis
- This review evaluates the effectiveness of artificial intelligence (AI) in screening for referable diabetic retinopathy (RDR), highlighting its high diagnostic accuracy in real-world settings.
- A comprehensive search yielded 15 studies, showing AI's sensitivity at 95.33% and specificity at 92.01% for patient-level analysis, which indicates strong performance compared to trained human graders.
- Notably, AI's performance varies by healthcare setting, with a higher sensitivity in primary-level care (99.35%) compared to tertiary-level care (94.71%), suggesting that AI may be particularly beneficial in less specialized environments.
Objective: To assess the availability of refractive error correction services (RECS) in selected Zambian hospitals.
Methods: Between October 2021 and March 2022, we conducted a cross-sectional study design among 20 eye health service providers selected from 20 public health facilities offering RECS in 20 districts from 8 provinces of Zambia. A stratified random sampling technique was used to select study participants.

Introduction: There are insufficient healthcare providers to supply eye care services to the millions of people living with visual impairment in developing countries. Eye care providers may supply more efficient and effective services if supported by skilled managers. To help produce skilled managers, appropriate competencies for eye care managers in Sub-Saharan Africa were included in the curriculum for the Postgraduate Diploma in Community Eye Health course (PGDCEH) at the University of Cape Town.

The aims of this study were to describe causes of mortality in children enrolled in a phase IV trial comparing intradermal with percutaneous administration of Bacille Calmette Guerin, and to compare causes of mortality recorded on death certificates with those obtained by clinical record review combined with verbal autopsies (CR/VA).
Methods: For children who died, certified causes of death were compared with those determined by CR/VA.
