Official Title: Pilot Study on Ambulatory Intraocular Pressure and Blood Pressure Monitoring in Glaucoma
Brief Summary:
Purpose: To study the feasibility of a larger study by determining the tolerability of measuring blood pressure (BP) and intraocular pressure (IOP) over 24 hours in an ambulatory fashion with automatic devices.
Participants: 20 patients with moderate to severe normal tension glaucoma and 20 non-glaucomatous patients.
Procedures (methods): Both BP and IOP will be measured automatically in each participant in an ambulatory fashion during a 24-hour period. BP will be monitored using an appropriately sized cuff Oscar 2 (Suntech Medical, Morrisville, NC), which will be placed by a person trained in ambulatory BP monitoring devices. The device will be set up to automatically inflate every 30 minutes during the day and every hour during the night to measure and record the BP. IOP will be measured using Sensimed Triggerfish contact lens (Sensimed AG, Lausanne, Switzerland); the measurements will be taken and recorded every 10 minutes. The contact lens will be inserted by eye doctors (investigators). Both monitoring devices will be removed the following day.
