Brief summary
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.
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.
Interventions
BEHAVIORALalter drinking habits
if dehydration is apparent, more fluid intake is recommended
