Relationship Between 24-hour IOP Pattern and the 24-hour Blood Pressure Pattern in Patients With POAG

Read time: 1 mins
Last updated:10th Jan 2013
Interplay between the increasing IOP and decreasing blood pressure (BP) during the 24-hour period, especially in the nocturnal period, may lead to insufficient perfusion pressure of the optic nerve and contribute to the glaucomatous damage in adjunct to the antero-posterior vectorial mechanical impact on the lamina cribrosa, the translaminar pressure. Patients with progressive VF loss showed greater nocturnal BP dips than patients with stable VF. Reduced mean intraocular perfusion pressure (IOPP) was significantly associated with the extent of glaucomatous damage. How the nycthemeral IOP fluctuation influences glaucoma progression has not been studied in a prospective manner and remains to be elucidated. The purpose of this study is to assess the relationship between the 24-hour IOP fluctuation pattern and the 24-hour BP pattern in patients with primary open angle glaucoma (POAG). IOP fluctuations will be monitored with SENSIMED Triggerfish�, a portable investigational device using a contact lens sensor that monitors the IOP fluctuation continuously over 24-hours.
