Efficacy and safety of topical cyclosporine A 0.05% in vernal keratoconjunctivitis.
Singapore Medical Journal 2016 September
INTRODUCTION: While corticosteroids are an effective choice of treatment for severe vernal keratoconjunctivitis (VKC), their long-term use is restricted due to side effects. This study was conducted to evaluate the efficacy and safety of topical cyclosporine A (CsA) 0.05% in the treatment of VKC.
METHODS: A total of 30 patients with VKC that was resistant to topical corticosteroids, antihistamines and mast cell stabilisers were treated with topical CsA 0.05%. Patients were evaluated at Weeks 4, 8 and 12 after the initiation of therapy. Symptoms and signs observed before and after treatment were recorded and scores were assigned. Scores for symptoms and signs, the need for topical corticosteroids and ocular side effects were evaluated.
RESULTS: At baseline, the median values of the symptom and sign scores were 10.0 (range 5.0-18.0) and 6.0 (range 2.0-13.0), respectively. At Week 4 of treatment with topical CsA 0.05%, the median values of the symptom and sign scores were 3.0 (range 0-14.0) and 3.0 (range 0-8.0), respectively. The reductions in the symptom and sign scores were statistically significant. The reduction in the need for corticosteroid was statistically significant by Week 12 of therapy. No significant side effects were reported.
CONCLUSION: Topical CsA 0.05%, which can help to reduce corticosteroid usage, is an effective and safe alternative for the treatment of resistant VKC. Further studies are needed to determine the optimal duration of therapy and possibility of recurrence.
