Allergic rhinitis is characterized by recurrent episodes. Long duration of treatment is often needed. The topical nasal corticosteroids are important in the management of allergic rhinitis. Recently, it was reported some studies that topical nasal corticosteroids may cause to increase in the intraocular pressure (IOP). The aim of this study is to evaluate the short and long time effects of momethasone, which is a new drug used for the treatment of allergic rhinitis, and budesonid, on the intraocular pressure. Twenty nine patients were treated with momethasone furoate and 20 patients were treated with budesonid for 6 weeks. The mean follow-up time to evaluate the changes in the IOP was 50 days ( 40-58 days). There was no difference between the groups with regard to age, gender and pretreatment IOP. Just after the treatment of allergic rhinitis and one month later, the lOPs were compared to pretreatment lOP's in both groups and no statistically significant differences were found. We also, compared the pretreatment, just after the treatment and one month later after the treatment IOP values between the groups; and no statistically significant differences were found. We concluded that the steroids used nasally as long as one month during allergic rhinitis did not cause to increase in the IOP.
