To patch or not to patch? That is the question.

There is good Evidence that surgery around the eyes can result in orbital hemorrhage, the most severe complication of which is vision loss. Bleeding can occur with primary orbital operations as well as with eyelid procedures that extend beyond the septum, the most common being blepharoplasty. More than 168 cases of orbital hemorrhage after blepharoplasty have been reported, 19 of which were associated with permanent vision loss. It has been estimated that the incidence of orbital hemorrhage after blepharoplasty is approximately 1:2000 and that of permanent vision loss is 1:22000 (0.0045%).
