N2 - Purpose: To investigate the circadian and blood pressure (BP) reduction obtained with timolol maleate 0.5% solution administered twice daily versus timolol 0.1% in gel-forming carbomer administered in the morning in patients with primary open-angle glaucoma (POAG). Methods: This investigator-masked, crossover study prospectively enrolled naive POAG patients not receiving systemic cardiovascular medications. Following a baseline evaluation, they were randomized to receive a timolol 0.5% solution or timolol 0.1% hydrogel for 2 months and then switched to the alternative medication for a further 2 months. Intraocular pressure (IOP) phasing (sitting Goldmann tonometry at 10 am, 2 pm, 6 pm, and 10 pm and supine Perkins tonometry at 2 am and 6 am) and ambulatory home BP monitoring were measured at baseline and after each treatment period. Results: On the basis of a prospective sample size estimate, 28 patients were analyzed. Mean 24-hour IOP decreased from 23.1 ± 0.7 mm Hg at baseline to 18.9 ± 0.6 mm Hg after timolol 0.5% and 18.9 ± 0.8 mm Hg after timolol 0.1% hydrogel (P
