Study finds lack of VEGF can cause defects similar to dry macular degeneration

Scientists at Schepens Eye Research Institute have found that when the eye is missing a diffusible form of vascular endothelial growth factor (VEGF), i.e. one that when secreted can reach other cells at a distance, the retina shows defects similar to "dry" macular degeneration, also called geographic atrophy (GA). This finding, published in the November 3, 2009 print edition of PNAS (Proceedings of the National Academy of Sciences), not only increases the understanding of the causes of this blinding disease, but it may also impact the use of anti-VEGF drugs, such as Lucentis, which are designed to neutralize VEGF in eyes with "wet" macular degeneration.
