PURPOSE: The aim of this study was to demonstrate the efficacy of cyclosporine A 0.1% cationic emulsion (CsA CE) eye drops 4 times a day in pediatric patients affected by a moderate form of vernal keratoconjunctivitis (VKC).
METHODS: This was a prospective study of pediatric patients, aged 5-16 years, with an active moderate form of VKC who were poor responders to topical antihistamines treatment and were treated 4 times a day with CsA CE. The clinical signs were graded for analysis as follows: hyperemia, tarsal papillae, and limbal papillae.
RESULTS: Twenty-eight patients (22 males and 6 females) with a minimum follow-up period of 3 months were included in the analysis. Statistical analysis excluded tarsal papillae because of the very low baseline value. The clinical score of hyperemia and limbal papillae improved from the first evaluation and was maintained over the follow-up. No side effects were noted.
CONCLUSION: CsA CE has been proposed as a treatment for severe forms of VKC. This study has shown that administration 4 times a day is also effective in the treatment of moderate forms of VKC in children.
