AIMS: To evaluate the ocular hypotensive effects and tolerability of the once daily fixed combination latanoprost-timolol versus twice daily 0.50% timolol associated or not with once daily latanoprost in patients suffering from Primary Open-Angle Glaucoma (POAG). METHODS: We compared the effects of such a combination with those of 0.50% timolol alone twice daily in a group of 24 patients and with the effects of timolol 0.50% twice daily associated with once daily latanoprost in a second group of 20 patients with a follow-up of 24 months. RESULTS: In the first group of patients after one month the Intraocular Pressure (IOP) was reduced from a mean of 19.93 to a 17.04 mmHg. This reduction remained stable with a mean value of 17.00 mmHg at the third month, of 16.49 mmHg at the sixth month, of 17.04 at the twelfth month, 16.00 at the eighteenth month, and of 15.86 mmHg in the twenty-fourth month. In the second group there was a statistically significant reduction from 19.4 to 16.84 mmHg after one month. This reduction remained constant with mean values of 16.47 at the sixth month, of 16.20 at the twelfth month and of 16.00 mmHg at the twentyfourth month of treatment. CONCLUSIONS: The once daily latanoprost-timolol combination was shown to furtherly reduce the Intraocular Pressure (IOP) (p=0.001) and to maintain under control the intraocular pressure for the observation period (24 months). Both topical and systemic side-effects were scarse and tolerability was good.
