This prospective, epidemiological British Ophthalmological Surveillance Unit study into ophthalmic complications of functional endoscopic sinus surgery aimed to determine the minimum incidence, presenting features and management throughout the UK.

Cases of ophthalmic complications of functional endoscopic sinus surgery, between February 2016 and February 2018, were identified through the British Ophthalmological Surveillance Unit reporting card system. Reporting ophthalmic consultants were sent an initial questionnaire, followed by a second questionnaire at six months.

Twenty-six cases of ophthalmic complications of functional endoscopic sinus surgery were reported. The majority (16 cases (62 per cent)) had limitations of ocular motility at presentation. The most common final diagnosis was rectus muscle (33 per cent) and nasolacrimal duct trauma (27 per cent). Using national data, this study reports a minimum incidence of ophthalmic complications of functional endoscopic sinus surgery in the UK of 0.2 per cent over two years.

In terms of ophthalmic complications, functional endoscopic sinus surgery is shown to be safe. Ophthalmic complications are rare, but when they do occur, they commonly result in rectus muscle trauma, often requiring surgical intervention.

To document the results of endoscopic orbital decompression performed in a group of patients with thyroid eye disease in order to improve cosmesis.

A retrospective case review was performed of all patients who had undergone endoscopic orbital decompression for cosmesis in our departments during the period January 1996 to September 2002. A postal questionnaire was sent to all patients who had undergone the operation, in order to assess patient satisfaction.

Twenty orbits of 15 patients underwent endoscopic decompression. For all orbits, the reduction in proptosis was 3.7±2.2 mm (mean±standard deviation; t = 6.5, p = 0.001). For 16 of the endoscopic decompressions (89 per cent), patients reported that they were satisfied with the appearance of their eye post-operatively, and all patients reported a reduction in eye prominence post-operatively.

Endoscopic decompression is an effective procedure for improving cosmesis in patients with inactive thyroid eye disease.
