Evaluation of Morphological Changes in the Retina Using OCTA in Patients with Diabetic Macular Edema Treated with
Aim:
To evaluate changes in the vascular density of the deep and superficial capillary plexus of the retina, the area of the foveal avascular zone, central retinal thickness, and best corrected visual acuity in patients with diabetic macular edema treated with anti-VEGF agents.
Material And Methods:
In a prospective study at the Ophthalmology Clinic of FNHK, we evaluated a group of 41 eyes of 30 patients (19 men and 11 women) with diabetic macular edema treated with Lucentis or Eylea. The average age of the patients was 61.7 ±11.3 years. Average initial visual acuity was 64.4 ±9.1 letters on ETDRS optotypes. During the one-year follow-up period we monitored the density of the deep and superficial retinal capillary plexus using OCTA. We evaluated OCTA scans with the ImageJ program at 3, 6, 9, and 12 months. Additionally, the area of the foveal avascular zone, central retinal thickness, and best-corrected visual acuity were measured.
Results:
During the one-year follow-up period there was a statistically significant change in both retinal capillary plexuses, with the density of the deep capillary plexus increasing (p.
