Diabetic patients on insulin or oral medications, with diabetes for over 7 years, or aged 50-66, have the highest risk of diabetic retinopathy. This helps prioritize patients for urgent retinal screening.

Area of Science:

  • Ophthalmology
  • Endocrinology
  • Diabetology

Background:

  • Diabetic retinopathy is a leading cause of vision loss.
  • Early detection and intervention are crucial for preventing severe visual impairment.
  • Risk stratification aids in efficient screening program design.

Purpose of the Study:

  • To identify key factors predicting high risk of diabetic retinopathy.
  • To enable prioritization of diabetic patients for retinal photographic screening.
  • To enhance the efficiency of diabetic retinopathy screening programs.

Main Methods:

  • Retrospective case survey of 888 diabetic patients.
  • Analysis of patient demographics, biochemical characteristics, and urinary albumin excretion.
  • Logistic regression to determine significant risk factors for diabetic retinopathy.

Main Results:

  • Prevalence of non-proliferative diabetic retinopathy was 18.1%; proliferative was 2.4%.
  • Insulin/oral hypoglycemic drug treatment (OR 14.7), diabetes duration ≥7 years (OR 3.6), age 50-66 (OR 2.1), and albuminuria (OR 2.2) were significant risk factors.
  • Hypertension, obesity, and sex were not significant risk factors.

Conclusions:

  • Diabetic patients can be risk-stratified for retinal screening urgency.
  • Treatment modality and diabetes duration are key ranking factors.
  • Prioritizing high-risk patients improves screening efficiency and early detection of asymptomatic diabetic retinopathy.
