Further study details as provided by Technische Universität Dresden:

Primary Outcome Measures:
  • changes in body-fluid balance [ Time Frame: 1 week ] [ Designated as safety issue: No ]
    The influence of hemodilution on body-fluid balance in patients with retinal vascular occlusion is examined

Secondary Outcome Measures:
  • number of participants with dehydration [ Time Frame: 1 week ] [ Designated as safety issue: No ]
    All patients are asked to fill in a questionnaire concerning their drinking habits (thirst, fluid intake). Patients body-fluid balance during hemodilution is measured with bioimpedance spectroscopy (Body Composition Monitor, Fresenius)

Estimated Enrollment: 30
Study Start Date: January 2013
Estimated Study Completion Date: December 2013
Estimated Primary Completion Date: October 2013 (Final data collection date for primary outcome measure)
retinal vascular occlusion
Patients with retinal vascular occlusion undergo a hematocrit dependent 5 day hemodilution

Detailed Description:

Patients with retinal vascular occlusion who are hospitalized for hemodilution and cardiovascular risk assessment are asked to report their drinking habits. Hydration status before and during hemodilution is assessed with a body-fluid analyzing scale.
