Diabetic retinopathy: Knowledge, awareness and practices of physicians in primary-care centers in Riyadh, Saudi...

Diabetic retinopathy (DR) is a serious cause of irreversible blindness and is the most common complication of diabetes. Annual fundus examination for diabetics aids in the prevention of blindness and allows intervening at a timely manner. As primary care physicians (PCP) are the main providers for diabetic care in Saudi Arabia, we aim to evaluate the current knowledge and awareness, and to assess practices among PCP regarding DR.

We conducted a cross-sectional study covering 46 randomly selected primary-care centers in Riyadh during October 2015. A Self-administered questionnaire was distributed to PCP containing 3 sections. The first section covered participants' demographics and professional background. The second section contained multiple-choice questions on knowledge related to diabetes and DR. The third section was to assess physicians' practices.

A total of 216 PCPs completed the questionnaire. The mean overall knowledge score was 57 ± 14 out of 100. There was a significant difference in knowledge score between physicians who had obtained a subspecialty degree in family medicine compared to others (59 ± 14, 53.3 ± 14 respectively; P = 0.003). Only 19% of PCPs were aware of anti-vascular endothelial growth factor (VEGF) injections as a modality of treatment. A defect was found in the screening and follow-up of type 1 diabetics, and only 24% of physicians correctly referred patients with type 1 diabetes to an ophthalmologist.

Our study uncovered areas of defects in knowledge among PCP regarding DR. This needs to be addressed in future seminars and workshops with an emphasis on the proper ophthalmological screening and management of diabetic patients.
