Purpose:
Subconjunctival corticosteroid injection (SCI) for nonnecrotizing anterior scleritis remains controversial, partly because long-term follow-up is not available. This study documents the efficacy and adverse effects of SCI.
Design:
Retrospective, noncomparative, interventional case series.
Participants:
Thirty-eight eyes of 35 patients with nonnecrotizing, noninfectious anterior scleritis resistant to prior systemic or local therapy.
Intervention:
Subconjunctival triamcinolone acetonide injection.
Main Outcome Measure:
Persistence or resolution of signs and symptoms of anterior scleritis and development of complications.
Results:
Thirty-six of 38 eyes had complete resolution of signs and symptoms within 6 weeks of SCI. Fifteen eyes had follow-up of > or =30 months. There were no instances of scleral melting or perforation; adverse events included subconjunctival hemorrhage (5 patients), transient ocular hypertension without evidence of glaucoma (4 patients), cataract (2 patients), and glaucoma (2 patients). Subconjunctival corticosteroid injection resulted in reduced dependence on systemic medications.
Conclusion:
Subconjunctival corticosteroid injection in eyes that failed other therapies is effective, reduces dependence on systemic medications, and did not result in scleral necrosis over a median follow-up period of 29 months.
