What this Trial Is About
Researchers are studying diabetic retinopathy DR, a common eye condition in adults with type 2 diabetes, to understand how changes in the eyes blood vessels and structure may predict worsening of DR and related heart problems. This observational study includes about 1,000 adults aged 35 to 90 years and aims to explore the link between eye changes and cardiovascular complications over one year. It also uses past medical and imaging data from previous visits within the last 1 to 5 years to enhance findings. The study focuses on analyzing central and peripheral retinal lesions through advanced imaging and clinical data to see how they relate to DR progression and cardiovascular risks. The data collected will help build a high-quality database to support artificial intelligence models predicting DR severity and cardiovascular outcomes. No treatments are given the study observes existing health information and imaging results. Participants will be monitored over 12 months with eye imaging, clinical evaluations, and collection of cardiovascular and diabetes-related data. Researchers will measure changes in DR staging, visual acuity, and occurrences of major heart events. Additional assessments include detailed retinal features, blood sugar levels, and blood pressure correlations. The study aims to improve understanding of DR and cardiovascular risks in people with type 2 diabetes, lasting from initial data collection through one year of follow-up.
