Research Article: Altered Spontaneous Brain Activity and Its Predictive Role in Patients with Central Retinal Artery Occlusion Using fMRI and Machine Learning

Date Published: 2023-08-18

Introduction:
Central retinal artery occlusion (CRAO) is an ophthalmic emergency which is analogous to an acute stroke of the eye. It typically presents as severe, painless and sudden visual loss in the affected eye. Typical early-phase characteristics include retinal swelling, a cherry red spot in the macula, edema and whitening of retinal inner layers. Later phase observations include thinning and atrophy of the inner retinal layers, further vessel attenuation and flattening of the foveal depression. The incidence of CRAO has…
