Retinal artery occlusion

Research output: Chapter in Book/Report/Conference proceedingChapter


Retinal artery occlusions (RAO) are characterized by the sudden obstruction of the arterial blood flow in the retinal circulation with consequent ischemic damage to the retina. RAO can be subdivided into several forms, including central retinal artery occlusion (CRAO) and Branch retinal artery occlusion (BRAO). Patients affected by CRAO experience a sudden, monocular loss of vision. On fundus biomicroscopy, if the retinal obstruction is incomplete a slight gray haze may be visible, but when the flow blockage is complete a progressive whitening and swelling of the inner retina develops. Patients affected by BRAO complain of sudden, partial or complete, visual loss associated with visual field damage. The area concerned by the BRAO shows evidence of acute retinal ischemia corresponding to the distribution of the occluded branch retinal artery. At present, there is no generally agreed treat
