Purpose: To describe and compare the parafoveal vascular density in healthy and diabetic patients by Optical Coherence Tomography Angiography (OCT-A) in a reference hospital.

Methods: Transversal prospective descriptive study, in which we analyzed two groups. One with a healthy population and one with diabetic patients. All participants underwent OCT-A with a swept-source OCT (Triton DRI-OCT, Topcon, Tokyo, Japan). Data was analyzed and compared using SPSS-PASW-Statistics 18.

Results: We analyzed 144 eyes (100%), of which 101 were female (70.1%) and 43 male (29.9%). The mean age was 45.91 with a minimum of 45 years and a maximum of 89. Parafoveal vascular density was measured, finding an average of 19.35% in the total number of patients studied. Patients were divided into two groups: Group A (control) with 90 eyes, and group B (diabetics) with 54 eyes. The vascular density of the healthy patients (group A) was compared with that of the diabetic patients (group B), finding an average of 20.51% and 17.40% respectively (p<0.003)

Conclusions: There is a decrease in parafoveal vascular density in diabetic patients compared to healthy subjects. This parameter decreases accordingly to age and there was no significant difference in the gender in our study (p=0.085).
