Summary
Diabetic retinopathy incidence was 31.3% in Saudi patients. Long diabetes duration, poor control, and nephropathy are key risk factors for retinopathy, emphasizing optimal glycemic control.
Area of Science:
- Ophthalmology
- Endocrinology
- Public Health
Background:
- Diabetic retinopathy is a leading cause of vision loss.
- Understanding incidence and risk factors is crucial for prevention.
Purpose of the Study:
- To determine the incidence of diabetic retinopathy.
- Identify associated risk factors in a Saudi diabetic population.
Main Methods:
- Study included 502 patients with diabetes mellitus.
- Classified patients into insulin-dependent (IDDM) and non-insulin-dependent (NIDDM).
- Utilized logistic regression to analyze risk factors.
Main Results:
- Overall retinopathy incidence was 31.3% (42.5% in IDDM, 25.3% in NIDDM).
- Significant risk factors included older age, insulin use, long diabetes duration, poor glycemic control, and nephropathy.
- Long diabetes duration was the most significant independent risk factor.
Conclusions:
- Optimal glycemic control is vital for preventing diabetic retinopathy.
- Modifiable risk factors like hypertension and high cholesterol warrant attention.
