AIM: To investigate the curative effect of conjunctival cryocoagulation in treatment of vernal conjunctivitis.

METHODS: Totally, 80 cases(160 eyes)with vernal conjunctivitis, treated from October 2008 to May 2010 in our hospital were randomly divided into two groups with 40 cases(80 eyes)for each group.Group A received conjunctival cryocoagulation combined with Tobradex eye dropping, and group B was managed with Tobradex eye dropping. The curative effect and adverse effect were observed and recorded 1 month, 3 months and 2 years after the treatment. The therapeutic effect was classified as cured,improved and ineffective.

RESULTS: The total effective rate in group A was higher than that in group B with a statistically significant difference(P<0.05)at 1 month, 3 months and 2 years after the treatment. The adverse effect was found in 7 cases in group A and 3 cases in group B, with no statistic difference(P>0.05).

CONCLUSION:Conjunctival cryocoagulation is an effective method for vernal conjunctivitis.
