[Results of the use of betoptik (betaxolol) in the treatment of primary glaucoma].

Effect of instillations of 0.5% betaxolol solution (Alcon) on intraocular pressure, ocular hydro- and hemodynamics, function, systemic arterial pressure, and pulse was studied in 35 patients (57 eyes) with primary open-angle glaucoma. The effects of betoptic and arutimol on the eyes are compared. Betoptic is characterized by a marked hypotensive effect explained by depression of aqueous humor production. The drug does not influence ocular function and hemodynamics. Comparison of the hypotensive effects of betaxolol and arutimol has shown that arutimol more effectively reduces intraocular pressure.
