Analysis of clinical features of visual impairment caused by endoscopic sinus surgery

Abstract

Objective To investigate the causes, clinical features, treatment and prognosis of chronic sinusitis and nasal polyps with endoscopic sinus surgery. Methods A total of 10 patients (10 eyes) from clinic of Xi’an No.4 Hospital between January 2001 and December 2016 due to vision loss caused by endoscopic sinus surgery were prospectively examined. All patients were enrolled and administered visual acuity testing, ophthalmic examinations, color photography, and other clinical observations. Results Ten cases of ocular complications occurred, including central retinal artery occlusion in 1 case, optic nerve injury in 6 cases, orbital hemorrhage in 2 cases, and orbital infection in 1 case. Conclusions The complications of endoscopic sinus surgery in patients with chronic rhinosinusitis and nasal polyps are complex, and the preparation, familiarity with nasal endoscopic resection and skilled operation can reduce the occurrence of complications. Timely detection of eye complications can reduce the risk of serious consequences. Visual impairment caused by endoscopic sinus surgery is difficult to treat and result in poor prognosis.
