PURPOSE: We sought to characterize the long-term outcomes and complications of subconjunctival triamcinolone acetonide injection (STI) for non-necrotizing, noninfectious anterior scleritis. DESIGN: Retrospective, interventional, noncomparative, multicenter study. PARTICIPANTS: Sixty-eight eyes of 53 patients from 9 participating hospitals in the United States, Singapore, and Australia. Only eyes with 6 or more months of follow-up were included. INTERVENTION: Subconjunctival injection of 2 to 8 mg of triamcinolone acetonide was administered to eyes with non-necrotizing, noninfectious anterior scleritis. MAIN OUTCOME MEASURES: Resolution of signs and symptoms, time to recurrence of scleritis, and side effect profile. RESULTS: Median follow-up was 2.3 years (range, 6 months to 8.3 years). Sixty-six eyes (97.0%) experienced improvement of signs and symptoms after 1 injection. Twenty-four months after a single injection, 67.6% of eyes remained recurrence-free, whereas at 48 months, 50.2% were recurrence-free. Some 55.0% of patients who had adverse effects from systemic medications were off all systemic medications at last follow-up; 55.0% of patients who were taking systemic medications at the time of first triamcinolone acetonide injection were not taking prednisone and immunosuppressants at this time; 76.2% of patients still requiring systemic agents had associated systemic disease. Fourteen eyes (20.6%) had ocular hypertension not requiring intraocular pressure (IOP)-lowering therapy. Two eyes (2.9%) were treated with topical IOP-lowering agents alone, and 2 eyes required surgical intervention for glaucoma. None developed scleral necrosis or melt. CONCLUSIONS: This retrospective, international study carried out at 9 hospitals suggests that STI can treat non-necrotizing, noninfectious anterior scleritis with side effects limited to elevated IOP in a few patients. Although no cases of scleral melt or necrosis were observed, we cannot definitively conclude that this may not occur after STI. Intraocular pressure should be closely monitored after STI. Subconjunctival triamcinolone acetonide injection may be useful as adjuvant therapy or to decrease systemic medication burden.
