Clinical trial of the topical use of disodium cromoglycate in vernal, allergic and chronic conjunctivitis.

Thirty-three patients were treated with disodium cromoglycate (DSCG). Of these 5 had vernal conjunctivitis, 18 had allergic conjunctivitis and 10 had mild chronic conjunctivitis in which the exact aetiology could not be determined. 70% of patients with DSCG as the only medication achieved at least some beneficial effect being almost exclusively in the groups of either vernal or allergic conjunctivitis. The basic trend seemed to indicate a reduction in severity during the treatment with DSCG in allergic diseases.
