[Comparative multicenter study of carteolol eyedrops with other beta blockers in 768 patients under normal conditions].

In an open multi-center study involving 768 patients the efficacy and tolerability of Carteolol eye drops as compared to other beta blockers were investigated. The patients started to use the new medication without a prior washout period. In patients who were well stabilized (57%), IOP either did not change when the medication was switched to Carteolol (73%) or it actually decreased. In 78% of the patients who had not responded altogether satisfactorily to the pretreatment, Carteolol eye drops lowered IOP to a tolerable level of 21 mm Hg or less without using any comedication. IOP remained hypertonic under Carteolol in only 19% of the cases. Fewer systemic and local side effects were observed under Carteolol therapy. Patients had fewer problems going upstairs. Burning after installation decreased by 25% to 2%. Even fluorescein-positive corneal findings almost completely disappeared under Carteolol.
