      OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY OF THE FOVEAL AVASCULAR ZONE IN CHILDREN WITH A HISTORY OF TREATMENT-REQUIRING RETINOPATHY OF PREMATURITY

      Purpose: To examine the characteristics of the foveal vascular structure of patients with retinopathy of prematurity (ROP) by optical coherence tomography angiography. Methods: Ten patients with a history of laser photocoagulation or cryopexy treatment for Stage 3 (Zone ≥ II) ROP and 10 normal subjects (controls) were included. Foveal avascular zone, vessel density, vessel length, and vascular diameter index were measured by optical coherence tomography angiography using the 3 × 3-mm Early Treatment Diabetic Retinopathy Study (ETDRS) sectors. Results: The median foveal avascular zone values of the patients with ROP and controls were 0.103 mm2 and 0.260 mm2, respectively (P ...
