Abstract
AbstractThe retinopathy remains the principal severe ophthalmologic complication of neonates with a gestationalage of 32 weeks or less. It’s a major cause of lifelong blindness beginning in infancy. As many other ocular pathologies, including diabetic retinopathy, and age‐related macular degeneration, result in vision loss because of aberrant neoangiogenesis. A common feature of these conditions is the presenceof hypoxic areas and overexpression of the proangiogenic vascular endothelialgrowth factor (VEGF).Its prevantion can be made by a better management of the oxygenation of these children but also by a better knowledge of the other risk factors. The prevailing current treatment, laser ablation of the retina, is destructive and only partially effective. Preventive and less destructive therapies are much more desirable. So, Angiogenesis, or the formation of new retinal blood vessels is a key feature of many proliferative retinal diseases including diabetic retinopathy,retinal vein occlusions, and retinopathy of prematurity.
