Cryosurgery in vernal catarrh.

Thirty four cases of vernal catarrh were treated with cryosurgery. During a mean follow up of 5 months this resulted in complete relief of symptoms and flattening of papillae in 94% of cases. Significant improvement in vision occurred in three out of six patients with decreased vision. Cryosurgery is recommended as a first line treatment for vernal catarrh.
