Brief Summary:
The aim of this study is to quantify and compare the foveal avascular zone (FAZ), the parafoveal and foveal vessel density of superficial (SCP) and deep capillary plexus (DCP) and retinal thickness in deprivation amblyopic eyes, fellow non-amblyopic eyes, and age-matched normal eyes, using optical coherence tomography angiography (OCTA). The FAZ, parafoveal and foveal SCP and DCP, and retinal thickness were measured in normal controls and at least 3 months postoperatively in children with unilateral cataract and compared between groups after adjusting for axial length and spherical equivalents.
