[Oculopression tonometry after argon laser trabeculoplasty].

A group of 26 patients (14 female and 12 male ranging in age from 49 to 84 years) who had primary open angle glaucoma underwent argon laser trabeculoplasty in one eye each. Shortly before the laser treatment, and one and twelve (7-14) weeks after the treatment suction cup oculopression tonometry was performed with an increase of intraocular pressure according to 1.8 x actual intraocular pressure. A therapeutically significant decrease of intraocular pressure was observed already one week thereafter, but findings become more significant after a longer follow up. The decrease of intraocular pressure and results of oculopression tonometry indicate that the measured resistance to aqueous outflow decreased significantly after argon laser trabeculotomy.
