Persistent limit- values for glaucoma

Hello,

My mother has had glaucoma for several years now, unfortunately detected in an already advanced state (current vision loss of about 75%).

Her doctor has tryed a number of different drops over the years, but average iop has never dropped below 19-21 (it varies from one visit to the next). She is followed by our oftalmologist every 60 days.

Her  medications are azopt in the morning, duotrav in the afternoon and xalacom at night.
