Subconjunctival Bevacizumab Injection in Treatment of Recurrent Pterygium
نویسنده
چکیده
Vascular growth factors such as vascular endothelial growth factor (VEGF) have been detected in pterygium [12-15].There is marked elevation of VEGF in pterygia in comparison to normal conjunctival samples [12-15]. Although the pathogenesis of pterygia is still poorly understood, their formation and progression are known to depend on neovascularization. It has been postulated that the development of pterygia depends on a changed angiogenic stimulator-to-inhibitor ratio. Jin et al. showed that pterygia contain drastically decreased levels of pigment epithelium-derived factor, angiogenic inhibitor, and elevated VEGF levels [15].
