Prevalence Of Diabetic Retinopathy In A Primary Care Setting Using Digital Retinal Imaging Technology

Area of Science:

• Ophthalmology
• Endocrinology
• Primary Care Medicine

Background:

• Diabetic retinopathy is a leading cause of preventable blindness.
• Early detection and management of diabetic retinopathy are critical in primary care settings.
• Digital retinal imaging offers a promising tool for screening and diagnosis.

Purpose of the Study:

• To determine the prevalence of diabetic retinopathy in a primary care population.
• To quantify the severity of diabetic retinopathy using established scales.
• To assess the utility of digital retinal imaging in primary care for diabetic eye disease.

Main Methods:

• A cohort of 200 patients with type 2 diabetes was recruited from a primary care setting.
• Clinical evaluation and fundus photography using digital retinal imaging technology were performed.
• Internationally accepted severity scales were used to grade retinopathy and maculopathy.

Main Results:

• The prevalence of diabetic retinopathy was 47.4%.
• The prevalence of diabetic maculopathy was 59.2%.
• A significant proportion (34.7%) had both retinopathy and maculopathy, often with short diabetes duration (≤5 years).

Conclusions:

• A high prevalence of diabetic retinopathy and maculopathy exists in primary care.
• Digital retinal imaging is effective for detecting diabetic eye disease in this setting.
• The findings highlight the need for proactive screening and management in early-stage diabetes.
