Drinking Habits of Glaucoma Patients and Age Matched Controls

November 26, 2015 updated by: Dr. Karin Pillunat, Technische Universität Dresden

Clinical Study to Evaluate the Drinking Habits of Glaucoma Patients and Age Matched Controls

The purpose of this study is to examine if a chronic dehydration is a risk factor for the developement or progression of some forms of glaucoma.

Conditions

Intervention / Treatment

Detailed Description

Glaucoma patients who are hospitalized for diurnal intraocular pressure measurements and glaucoma assessment are asked about their drinking habits. Objective evaluation of hydration status is assessed with the Body Composition Monitor (Fresenius). Retinal Vessel Analysis and Laser Doppler Flowmetry are investigated in subgroups.

The control group are also hospitalized patients who do not suffer from glaucoma.
