NCT01943396

Brief Summary

In this research rheohemapheresis will be used for the treatment of patients with high-risk dry form of age-related macular degeneration. Correction of rheologic parameters and activation of retinal functional reserves after the therapy will positively influence functional condition of retina. The newest special electrophysiologic methods will be used to determine retinal changes in time. The investigators will also evaluate some important immunologic factors and complement changes as well as define indication criteria more precisely.

Outcome Measures

Primary Outcomes (1)

  • Electroretinography

    Evaluation of functional changes in single retinal layers and areas by newest special electrophysiologic methods

    2.5 years

Secondary Outcomes (1)

  • immunologic parameters changes

    2.5 years

Study Arms (2)

Rheohemapheresis

EXPERIMENTAL

Each treated patient will receive a series of 8 rheohemaphereses (cascade filtration) within 10 weeks. Best-corrected visual acuity, electroretinography and drusenoid retinal pigment epithelium detachment area will be examined. Changes of selected special immunologic parameters will be measured.

Procedure: rheohemapheresis

without rheohemapheresis

NO INTERVENTION

Into the group the patients will be randomized with the same disease but without rheohemapheresis

Interventions

Each treated patient will receive a series of 8 rheohemaphereses (cascade filtration) within 10 weeks. One plasma volume will be washed.

Also known as: rheopheresis, double plasma filtration, cascade filtration
Rheohemapheresis

Eligibility Criteria

AgeUp to 85 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • Patients with AMD in the stage of soft drusen, grade 1-3 according to European Eye Study (EURYEYE) (see reference No 1), body weight over 50 Kilo and with other feasible indications for aphereses therapy (peripheral veins allowing vascular access to establish the extracorporal circuit).

You may not qualify if:

  • Study eye with exudative AMD
  • Study eye with concomitant retinal or choroidal disorder other than AMD
  • Study eye with significant central lens opacities and/or conditions that limit the view of the fundus
  • uncontrolled diabetes, uncontrolled arterial hypertension
  • insufficient antecubital venous access
  • haemato-oncological malignancies
  • patients who are unwilling to adhere to visit examination schedules . poor general condition (serious diseases - infections,cardiovascular or cerebral insufficience, severe IHD)
