What this Trial Is About
Diabetic retinopathy (DR) is a common cause of preventable vision loss globally, affecting about 22-26% of people with diabetes, with vision-threatening cases in about 6%. This research aims to determine the local prevalence, severity, and risk factors of DR among diabetic patients at Gia Dinh Family Hospital in Da Nang, Vietnam. Understanding these factors is important to improve screening and management to reduce vision loss in this population. The study observes diabetic patients who have undergone eye examinations including dilated fundus examination and optical coherence tomography (OCT) during the period from January to September 2025. These patients are identified through the hospital's electronic health records. No treatments are given; the study collects and reviews clinical and laboratory data from medical records to analyze DR prevalence and associated risk factors. Participants will have had their eye exams and medical records reviewed for diabetes diagnosis and key health information. Researchers will measure how common DR is, at what stages it occurs, and which health factors are linked to DR presence. The main outcome is the prevalence of any stage of DR at baseline. The study will conclude by March 2026, with data collected retrospectively from the 2025 study period.
