Oxymetazoline in the treatment of allergic and non-infectious conjunctivitis.

In a double-blind study of 141 patients, 0.025% oxymetazoline ophthalmic solution was compared with its vehicle in the treatment of allergic and non-infectious conjunctivitis. There was a marked difference in response at the first evaluation. By the tenth day (second evaluation) the total improvement in hyperaemia was 95% for oxymetazoline compared to 54% for the placebo. Oxymetazoline's decongestant effect in the eye matches its effect as a nasal vasoconstrictor.
