Summary

The goal of this retrospective observational study is to evaluate the prevalence and severity of diabetic retinopathy (DR) and to identify associated risk factors among patients with diabetes mellitus at Gia Dinh Family Hospital in Da Nang, Vietnam. The main questions it aims to answer are: 1. What is the prevalence and distribution of different stages of diabetic retinopathy among diabetic patients at this hospital? 2. Which clinical and laboratory factors are associated with the presence of diabetic retinopathy?

Detailed description

Diabetic retinopathy (DR) is a leading cause of preventable visual impairment worldwide. Global estimates suggest that approximately 22-26% of people with diabetes have some degree of DR, with about 6% experiencing vision-threatening disease. The burden is expected to increase substantially, particularly in low- and middle-income countries. Vietnam is experiencing a rapid rise in diabetes prevalence, however, data from Central Vietnam, particularly from multidisciplinary general hospitals, remain limited. This study aims to evalutate the local prevalence, severity distribution, and associated risk factors of DR in a general hospital in Da Nang which is essential to inform screening strategies, optimize management, and reduce preventable vision loss.
