Study of the Clinical and Biological Efficacity of NAAXIA SINE® in Vernal Keratoconjunctivitis

Study of the Clinical and Biological Efficacity of NAAXIA SINE® in Vernal Keratoconjunctivitis

To assess the clinical and biological efficacity of preservative free NAAGA eyes drops in vernal keratoconjunctivitis

The objective of this pilot study is to evaluate the clinical and biological efficacy of preservative free NAAGA eyedrops in VKC -by in particular the levels of ECP and MPO in tears- comparatively to the activity of levocabastine eyedrops.

Inclusion Criteria:

• mild or moderate : clinical score >3 and <= 14, calculated from 4 major symptoms (itching, tearing, photophobia, foreign body sensation) and 6 major clinical signs (conjunctival erythema, conjunctival chemosis, discharge, papillae, limbal infiltrates and corneal epithelial disease)
• age >= 4 years old
