Abstract
The purpose of this study is to report a case of combined hemiretinal vein occlusion and cilioretinal artery occlusion (CLRAO), in which the development of the CLRAO was substantially delayed. This interventional case report illustrates the sequential development of a cilioretinal artery occlusion following a hemiretinal vein occlusion with colour fundus and fluorescein angiogram photographs. Systemic examination revealed previously unrecorded hypertension for which her general practitioner commenced treatment. The patient developed an inferior visual field defect however made a visual recovery to 20/40 at 6-month follow-up. In this report, the risk factors and the likely pathogenesis for such an event are studied.
