Trial Outcomes & Findings for The Diurnal and Nocturnal Effect of Pilocarpine on Intraocular Pressure and Ocular Perfusion Pressure (NCT NCT02754570)

NCT ID: NCT02754570

Last Updated: 2019-11-07

Results Overview

Subjects will be enrolled at the first visit. Patients already on latanoprost may proceed immediately with the second visit. Patients on a different prostaglandin analog medication will be switched to latanoprost for at least 6 weeks. At second visit, intraocular pressure and blood pressure will be measured every 2 hours for a 24-hour period. At any point over the next 4 weeks, another 24-hour visit will be performed. This time, a dose of pilocarpine 2% will be administered at 4 different times in addition to the latanoprost . As before, intraocular pressure and blood pressure will be measured every 2 hours. After visit 3, subjects will return to their prior treatment regimen. Change in the intraocular pressure from the second and the third visit will be determined. 8 diurnal readings and 4 nocturnal readings were averaged separately during both Visit 2 for the PGA Monotherapy and Visit 3 for Pilocarpine+PGA

PRIMARY outcome

Timeframe: Two 24-hour visits: Baseline/Visit 2; Up to week 4/Visit 3

Population: Patients who are using a prostaglandin analog (PGA) will be monitored at visit two. At visit 3, pilocarpine will be added four times per day to the PGA therapy.

Subjects will be enrolled at the first visit. Patients already on latanoprost may proceed immediately with the second visit. Patients on a different prostaglandin analog medication will be switched to latanoprost for at least 6 weeks. At second visit, intraocular pressure and blood pressure will be measured every 2 hours for a 24-hour period. At any point over the next 4 weeks, another 24-hour visit will be performed. This time, a dose of pilocarpine 2% will be administered at 4 different times in addition to the latanoprost . As before, intraocular pressure and blood pressure will be measured every 2 hours. After visit 3, subjects will return to their prior treatment regimen. Change in the intraocular pressure from the second and the third visit will be determined. 8 diurnal readings and 4 nocturnal readings were averaged separately during both Visit 2 for the PGA Monotherapy and Visit 3 for Pilocarpine+PGA

SECONDARY outcome

Timeframe: Two 24-hour visits: Baseline/Visit 2; Up to week 4/Visit 3

Population: Patients who are using a prostaglandin analog (PGA) will be monitored at visit two. At visit 3, pilocarpine will be added four times per day to the PGA therapy.

Ocular perfusion pressure will calculated from the intraocular pressure and blood pressure measurements. At Baseline/Visit 2, intraocular pressure and blood pressure will be measured every 2 hours for a 24-hour period. At any point over the next 4 weeks, another 24-hour visit (Visit 3) will be performed. This time, a dose of pilocarpine 2% will be administered at 4 different times in addition to the latanoprost (PGA monotherapy). As before, intraocular pressure and blood pressure will be measured every 2 hours. 8 diurnal readings and 4 nocturnal readings were averaged separately during both Visit 2 for the PGA Monotherapy and Visit 3 for Pilocarpine+PGA
