Macular and Optic Nerve Microvascular Alteration in Relation to Axial Length, by Optical Coherence Tomography Angiography (OCTA)
Aim: To study the effect of axial length (AL) on quantitative characterization of macular and optic nerve microvasculature using optical coherence tomography angiography (OCTA) in healthy individuals. Methods: A cross-sectional study where participants were divided into 3 groups according to AL; A: ≤ 22.5 mm, B: 22.6– 24.5 mm, C: > 24.5 mm. Superficial vascular density (SVD), deep vascular density (DVD), foveal avascular zone (FAZ), and radial peripapillary capillary density (RPCD) were calculated using OCTA. Pearson correlation was run to identify the relation between AL and study parameters. Results: One hundred and twelve eyes of 56 participants (20 ...
