Clinical trial of topical disodium chromoglycate in vernal keratoconjunctivitis.

The clinical picture of Spring catarrh was studied in 96 cases. The duration of the disease was found to be 3.5 +/- 2.6 years. It exists all the year round with a higher frequency between April and August. Male children were affected about three times more frequently than females. The effect of DSCG was studied in 20 cases. It had a significant therapeutic effect. We advise a combined DSCG and corticosteroid treatment in the period of exacerbation.
