Abstract

Objective: To compare superficial retinal plexus (SCP) of the foveal avascular zone (FAZ) in patients of diabetes who have clinically insignificant diabetic retinopathy (CIDR) with Optical Coherence Tomography Angiography (OCTA) at Pakistan Navy Station (PNS) Shifa, Karachi.

Study Design: Quasi-experimental study

Place and Duration of Study: Department of Opthalmology, PNS Shifa, Karachi, Pakistan, from Jan 2022 to Jan 2024.

Methodology: Our study included a total of 100 eyes at PNS Shifa, Karachi, where 50 eyes were included in diseased group (Group I), who had diabetes but without any clinical findings, and 50 eyes in the age-matched control group (Group II). Retinal vascular density of SRP and size of FAZ in both groups was noted using SS-OCTA after doing Best Corrected Visual Acuity (BCVA) and detailed fundal examination and compared on data analysis.

Results: This study comprised a total of 50 patients, with 100 eyes, mean age being 46.20±7.17 years, ranging from 33.00 to 67.00 years, of which, 43(86.00%) were male and 7(14.00%) were females. Superficial vessel density of FAZ was found to be significantly increased in the Diabetic Retinopathy group as compared to the Non-Diabetic Retinopathy (p value < 0.001).

Conclusion: Our results showed that OCTA is an efficient tool for early detection of diabetic retinopathy in patients with clinically insignificant diabetic retinopathy.
