Abstract

PURPOSE
Locally administered corticosteroids have been widely used in the treatment of inflammatory eye disease. The main purpose of this study is to analyze the treatment effects and the complications of posterior subtenon steroid injection in uveitis patients. METHODS: Retrospective study was performed on 36 eyes of 32 patients diagnosed as uveitis and treated with subtenon steroid injection. RESULTS: Sixty eight consecutive injections of triamcinolone were performed, and the mean follow-up duration was 6.9 months (1~28 months). Visual acuity was improved in 28 (88%) of 32 patients, and mean time to improvement was three weeks after the injection. Intraocular pressure was increased (>21 mmHg) in 10 eyes (31%) of 10 patients, with mean onset of three weeks after the initial injection. The increased pressures was not controlled by medical treatment and additional filtration surgery was needed in 2 eyes (6%). Cataracts were newly developed or worsen in 5 eyes (15.6%) of 4 patients and 2 eyes underwent cataract surgery. CONCLUSIONS: Although a postrerior subtenon steroid injection effectively improved visual acuity in most uveitis patients, side effects, such as the increased intraocular pressure or cataract were developed. The complication rate as well as treatment effect should be taken into consideration when using this treatment method.
