Popis: Pur po se: To evaluate the effects of latanoprost/timolol maleate and dorzolamid/timolol maleate fixed combinations on-24 hours intraocular pressure in patients with open-angle glaucoma. Ma te ri als and Met hod: Forty-eight eyes of 24 patients with open-angle glaucoma were enrolled in the study. They were randomized to receive fixed combinations of either latanoprost/timolol maleate (Group 1 - 24 eyes of 12 patients) or dorzolamid/timolol maleate (Group 2 - 24 eyes of 12 patients). Patients who achieved intraocular pressure of ≤ 21 mmHg 3 weeks after combined therapy were hospitalized and intraocular pressure was monitored at hour 06:00, 10:00, 14:00, 18:00, 22:00 and 02:00 for 24 hours. Diurnal and nocturnal fluctuations were determined by measurements done between 06:00 and 18:00 hours and between 22:00 and 02:00, respectively. Mean intraocular pressure and fluctuations of intraocular pressure between the two groups were compared. Re sults: There was no difference between the groups in terms of age, sex, visual acuity and cup/disc ratio (p>0.05). Three weeks after combined therapy, all patients achieved target intraocular pressure of ≤ 21 mmHg. There was no statistically significant difference between the two groups with regard to mean intraocular pressure over 24 hours (17.1±2.3 mmHg and 17.27±2.3 mmHg for Group 1 and Group 2, respectively; p>0.05). Diurnal fluctuations were 3.6 mmHg for Group 1 and 4.7 mmHg for Group 2; nocturnal fluctuations were 4.3 mmHg for Group 1 and 2.3 mmHg for Group 2. Diurnal fluctuations in Group 1 were lower than in Group 2, while nocturnal fluctuations were lower in Group 2 than in Group 1 (p
