[Nonpreserved topical steroids and lacrimal punctal occlusion for severe keratoconjunctivitis sicca].

Purpose: To analyze the efficacy of topical nonpreserved steroids before punctal occlusion in the treatment of severe keratoconjunctivitis sicca associated with Sjögren's syndrome.

Methods: We performed a prospective study including 15 patients, 30 eyes, (group 1) treated with topical nonpreserved steroids for 2 weeks and then punctal occlusion, and 15 patients, 30 eyes, (group 2) treated directly with punctal occlusion. Symptom severity (0-3+) and corneal fluorescein staining (0-9+) were evaluated after a week and after two months, and results were statistically compared between both groups with the t Student test.
