[Primary open-angle glaucoma. Effects of an eyedrop combining timolol and pilocarpine on the ocular pressure].
In a limited group of open angle glaucoma patients treated twice daily with timoptol 0.5% and having by this treatment a mean intra-ocular pressure of 21-22 mmHg, the association of timoptol 0.5% with pilocarpine 2% respectively, lowered the intra-ocular pressure to an average of 17.8 mmHg and 16.6 mmHg after one and three weeks of continuous treatment. For this study, the patients have been divided into 3 groups: A group treated with timoptol 0.5% alone throughout the 49 days of the study. A group treated with timoptol 0.5%-pilocarpine 2% (timpilo 2) from day 21 to day 49. A final group treated with timoptol 0.5% until day 21 and then with timoptol 0.5%-pilocarpine 4% (timpilo 4) through out day 49. These patients stopped the treatment before the end of the study. Intra-ocular pressures were measured on days 0, 21 and 49. We found a higher drop of pressure (-4.8 mmHg) in the timpilo 2 group than in the timoptol 0.5% group (-1 mmHg) before instillation as well as 2 hours afterwards (-5.25 mmHg and -2 mmHg respectively). The secondary local effects were due to miotics agents. The secondary systemic effects were those inherent to beta-blockers. These results are comparable with a multicentric study of 220 patients, therefore statistically significant.
