Visual disturbances have been reported as a consequence of acute severe blood loss. They are related to hypoperfusion related watershed infarcts in the posterior visual pathway apparatus. In this case report, we report the clinical course of a young male adult who suffered transient blindness following an assault in which he sustained deep cuts to the temporal and parietal regions of the scalp. He was managed in our hospital with copious infusion of intravenous fluid (normal saline) and subsequent transfusion of 2 pints of whole blood. Blindness persisted from less than one hour following assaut to 96 hours post admission. Blindness resolved completely by the 9th day of admission but was associated with a homonymous visual field defect.
