Pseudoxanthoma elasticum (PXE) is a rare hereditary systemic disease affecting mainly the skin, eyes and the cardiovascular system. Commonly, complicating choroidal neovascularization (CNV) of the central retina lead to a severely decreased visual acuity in the course of the disease. Onset of the symptoms varies with the extend of the PXE-associated findings.
In the past there has been no effective treatment for the disease's ocular complications. Recent studies in a limited number of patients with CNV treated with intravitreal injections of bevacizumab, an antagonist targeting vascular endothelial growth factor (VEGF), have shown a preservation of function and regression of CNV. An increase of visual acuity was reported in a subset of patients. Bevacizumab is a humanized antibody of which ranibizumab is a fragment.
This trial is initiated in order to investigate the effect of ranibizumab on functional outcome measures such as preservation of visual acuity as well as morphological outcome measures such as regression of CNV in angiography.
The safety and tolerability of ranibizumab will be investigated as well. As it has been tested on large numbers of patients suffering from age-related macular degeneration with only rare significant side effects or adverse events being reported, a good safety profile is assumed.
The study is conducted in a non-randomized, uncontrolled prospective setting at one center.
Patients will receive monthly injections over a period of one year.
