Diabetic retinopathy prevalence increases with diabetes duration, reaching 100% after 30 years. Early screening for vision-threatening diabetic retinopathy is crucial, especially after 10 years of diabetes.

Area of Science:

  • Ophthalmology
  • Endocrinology
  • Diabetology

Background:

  • Diabetic retinopathy is a leading cause of visual impairment.
  • Understanding risk factors and progression is vital for timely intervention.

Purpose of the Study:

  • To determine the occurrence and severity of diabetic retinopathy.
  • To investigate associations between diabetic retinopathy and diabetes duration, type, and other health conditions.

Main Methods:

  • Ophthalmoscopy and widefield fundus photography were used for retinal assessment.
  • Data collected from 328 outpatient diabetic patients, predominantly type 1.

Main Results:

  • Diabetic retinopathy confirmed in 59% of patients; proliferative retinopathy (PR) in 20%.

  • Retinopathy frequency rose from 15% (diabetes <5 years) to 100% (diabetes ≥30 years).
  • PR incidence increased with diabetes duration and was associated with nephropathy and cardiovascular complications.

    • Conclusions:

    • Diabetic retinopathy is highly prevalent and progresses with diabetes duration.
    • Intensified screening for vision-threatening retinopathy is recommended after 10 years of diabetes, earlier for poorly controlled cases.
