Evaluation of Subconjunctival Triamcinolone for Nonnecrotizing Anterior Scleritis

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. Retrospective, noncomparative, interventional case series. Thirty-eight eyes of 35 patients with nonnecrotizing, noninfectious anterior scleritis resistant to prior systemic or local therapy. Subconjunctival triamcinolone acetonide injection. Persistence or resolution of signs and symptoms of anterior scleritis and development of complications. 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. 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.

Tumor necrosis factor α blockade with infliximab for refractory uveitis and scleritis

Objective To assess the efficacy and safety of the anti–tumor necrosis factor α agent infliximab in treatment-resistant uveitis and scleritis. Design Retrospective, noncomparative interventional case series. Participants Seven patients with noninfectious ocular inflammatory disease that was refractory to alternative immunosuppression. These included one patient with idiopathic retinal vasculitis and panuveitis, one patient with intermediate uveitis, one patient with chronic juvenile anterior uveitis, three patients with scleritis, and one patient with scleritis and peripheral ulcerative keratitis. Four patients had an underlying systemic disease that was in remission in three cases. Intervention Infusions of infliximab, 200 mg, were given at 4-week to 8-week intervals, depending on the clinical response. Main outcome measures Clinical response, including symptoms, visual acuity, degree of scleral vascular engorgement, corneal thinning, anterior chamber activity, and posterior segment inflammation, reduction in concomitant immunosuppression, and adverse effects. Results The mean patient age was 47 years (range, 24–78), and four patients were female. The mean number of infliximab infusions was seven (range, 2–19), and the mean follow-up period was 12 months (range, 4–22 months). Six patients experienced a clinical improvement, with five achieving remission and significant reduction in immunosuppression. One patient showed an initial response but developed a delayed hypersensitivity response that precluded further treatment. No other adverse effects occurred. Conclusions Infliximab seems to be an effective and safe treatment for noninfectious uveitis and scleritis and may be indicated as rescue therapy for relapses of ocular inflammation or as maintenance therapy when conventional immunosuppression has failed. Further investigation of infliximab for treatment-resistant scleritis and uveitis is warranted.

An Analysis of Therapeutic Decision for Scleritis

To compare the long-term efficacy of different systemic therapeutic regimens for patients with noninfectious anterior scleritis to establish guidelines for institution of therapy. Therapeutic failure of systemic nonsteroidal anti-inflammatory drugs (NSAIDs), systemic steroidal anti-inflammatory drugs, and systemic nonsteroidal immunosuppressive drugs was evaluated in 132 patients with noninfectious anterior scleritis (diffuse, nodular, or necrotizing types). In patients with diffuse scleritis, therapeutic failure for initial regimens occurred in 7% of patients treated with NSAIDs, in 16% of patients treated with steroids, and in 27% of patients treated with immunosuppressive drugs. In patients with nodular scleritis, therapeutic failure for initial regimens occurred in 9% of patients treated with NSAIDs, in 28% of patients treated with steroids, and in 25% of patients treated with immunosuppressive drugs. Addition or substitution of steroids or immunosuppressive drugs as second- or third-line therapies helped control the scleritis. In patients with necrotizing scleritis, therapeutic failure for initial regimens occurred in 100% of patients treated with NSAIDs, in 91% of patients treated with steroids, and in 26% of patients treated with immunosuppressive drugs. In patients with diffuse and nodular scleritis, NSAIDs should be the initial choice; in case of therapeutic failure, steroids should be added or substituted as second-line therapy, tapering and discontinuing them as soon as possible while maintaining remission with continued NSAIDs; in case of therapeutic failure, immunosuppressive drugs should be added or substituted as third-line therapy. In patients with necrotizing scleritis, immunosuppressive drugs should be the initial choice.
