Delayed Optochiasmal Arachnoiditis following Intervention for a Subarachnoid Haemorrhage.

Abstract

Visual morbidity following a subarachnoid haemorrhage is common among survivors and it is usually the result of vascular ischaemia at the time of the initial insult. In this report, we present an unusual case of delayed, progressive visual loss following intervention for a ruptured anterior communicating artery aneurysm. We discuss the possible etiological factors and highlight potential diagnostic pitfalls.
