OCT-Based Interpretation of the Optic Nerve Head Anatomy in Young Adults with Vascular Optic Neuropathies

Vascular disease affecting the optic nerve head (ONH) is occasionally seen in young adults with no or few systemic risk factors. The aim of this study was to examine the anatomy of the ONH using optical coherence tomography (OCT) in young adults diagnosed with central retinal vein occlusion (CRVO), branch retinal vein occlusion (BRVO), central retinal artery occlusion (CRAO), branch retinal artery occlusion (BRAO), and anterior ischemic optic neuropathy (AION), in order to look for inherent and potentially predisposing anatomic anomalies.
