title: A case report of orbital haemorrhage associated with endoscopic sinus surgery and reversible sight loss: a multidisciplinary approach to management.
abstract: We report a case of intraoperative orbital haemorrhage as a complication of endoscopic sinus surgery performed under general anaesthesia. Initial unilateral complete visual loss occurred, but recovered due to accurate and early diagnosis combined with urgent surgical intervention. This patient's case is reported to illustrate the importance of early recognition of clinical signs and how a stepwise approach to management can result in a favourable visual outcome. Moreover, the mechanisms and pathophysiology of visual loss due to orbital haemorrhage following endoscopic sinus surgery are discussed.
