Efficacy of cryotherapy in vernal catarrh.

Cryotherapy of the palpebral conjunctiva with oral aspirin has been evaluated in mixed-type active vernal keratoconjunctivitis. The symptoms and signs were recorded on a four-point scale. In 15 patients, we used cryotherapy of the palpebral conjunctiva in 30 eyes (-60 degrees C to -80 degrees C for 30 seconds, repeating the freeze-thaw cycle 2-3 times).
