Backround And Objective: Screening for diabetic retinopathy (DR) is cost-effective when compared with disability loss for those who go blind in the absence of a screening program. We aimed to evaluate the sensitivity and specificity of a smartphone-based device for the screening and detection of DR.

Patients And Methods: A cross-sectional study of 220 patients with diabetes (440 eyes, all patients age 25 years or older) was completed.

  • - The study focused on understanding what factors influence diabetes patients in undergoing comprehensive eye examinations at a hospital in Douala, aiming to track when these tests are performed after diagnosis.

Uveal coloboma is a rare eye malformation caused by failure of the optic fissure to close during the fifth to seventh weeks of foetal life. The risk of retinal detachment increases with age in colobomatous eyes. Preventive measures such as early detection of the retinal break, prophylactic laser photocoagulation along the coloboma margin, confer a significant benefit in reducing this risk of retinal detachment.
