A single day of focused direct ophthalmoscopy training, supported by low-cost diagnostic and simulation tools, can improve glaucoma-related examination skills among allied ophthalmic personnel (AOP) students, according to a controlled pre-post study published recently in Eye.
Early detection of glaucoma remains a major challenge in many low-resource settings, where late presentation and limited specialist capacity contribute to avoidable blindness. The study authors note that, as of 2022, Zambia had only one ophthalmologist per 556,000 people, placing considerable responsibility for early glaucoma detection on AOPs working in district and provincial eye care services.
The study, led by Vrundaben Patel and colleagues, evaluated whether a short, targeted intervention could improve students’ ability to use direct ophthalmoscopy and assess optic discs for glaucomatous change. Thirty final-year AOP students at Levy Mwanawasa Medical University, Zambia, were randomized into two groups. The intervention group received one day of oral and practical training using ophthalmoscopy simulation eyes and the Arclight, a frugal solar-powered direct ophthalmoscope, and kept the device for continued practice. The control group undertook unguided ophthalmoscopy practice and returned the device.
Participants were assessed at baseline, immediately after training, and again one month later. Outcomes included glaucoma knowledge, direct ophthalmoscopy technique, recognition of glaucomatous optic disc features, and classification of discs as normal, abnormal non-glaucomatous, or abnormal glaucomatous.
Baseline scores were similar between groups – both groups improved over the study period, suggesting that structured exposure, repeated assessment, and practice alone can support skill development. However, the intervention group achieved greater gains in most assessed domains. At one month, improvements were significantly larger for overall knowledge, examination technique, and disc classification. Recognition of specific glaucomatous disc features improved similarly in both groups.
A notable finding was the limited previous ophthalmoscopy exposure among participants: 80 percent had performed direct ophthalmoscopy fewer than five times, despite being near the end of their training, highlighting a practical gap between curriculum completion and clinical readiness.
The study authors conclude that embedding frugal, competency-based ophthalmoscopy modules into AOP undergraduate curricula could strengthen glaucoma detection in high-burden, low-resource settings. They also suggest that modest gains in recognizing specific glaucomatous features may require reinforcement through refresher teaching, remote case-based mentoring, or continued supervised practice.
