  Purpose

Age-related macular degeneration is one of the major causes of blindness in the western world. There is an exsudative and a non-exsudative form of age-related macular degeneration.Most studies concentrate on the exsudative form. In the non-exsudative form the policy is generally watch and see, but patients are at risk to develop an exsudative form. So far, the only accepted therapy to reach stable disease in the non-exsudative form is high-dose supplementation of antioxidants. Another approach to improve visual acuity in patients with non-exsudative form of macular degeneration is rheohemapheresis treatment, an extracorporeal therapy where plasma is separated from blood cells. By the use of a hollow fiber filter plasma is depleted of high molecular weight proteins and reinfused. Others report describe the supplementation of lutein (a vitamin A derivative) as possible treatment option. However, none of the studies have yet examined a combination of rheohemapheresis and lutein supplementation.

Estimated Enrollment: 20
Study Start Date: March 2007
Estimated Study Completion Date: May 2012
Detailed Description:

Rheohemapheresis will be performed in 5 cycles. One cycle consists of 2 rheohemapheresis treatments on day 1 and day 4. A cycle lasts for 4 weeks and will be repeated every fourth week. During each treatment > 75% to 100% of patients total plasma volume has to be filtered.General medical reviews, ETDRS and Radner visual acuity assessment, ophthalmologic examinations, ocular imaging with OCT 3, autofluorescein imaging and infrared imaging, multifocal ERG, ocular echography, and blood examinations will be performed.
