Abstract
Choroidal neovascularization is a common cause of vision loss in patient with pathologic myopia, often resulting in irreversible central vision loss.This is particularly important because choroidal neovascularization secondary to pathologic myopia affect many people of working age. OCT is considered as very important tool in detection of CNV at which it was seen as highly reflective bright red band in the retina; the associated serous fluid was seen as hyporeflective spaces and might be associated with cystoid spaces in retina. Photodynamic therapy of CNV that invades the fovea has selective destruction of CNV with preservation of overlying neuro-sensory retina that relies on low intensity light exposure of tissue treatment with photosensitizer to produce photochemical effects. The visual outcome after PDT was better than the natural course of the disease as determined from untreated controls.(PDT) for CNV is an effective, safe, technically simple and well tolerable procedure that makes it possible not only to stabilize , but, in many cases to improve visual functions in myopic eyes, with evidence of recent CNV subfoveal and juxtafoveal but has some limitations of its use as in lesions greater than 5400 micron subject to laser spot size, myopic CNV < 50 % classic , other pure occult, RPE tears and high cost of procedure. Laser photocoagulation initially proved useful in preventing loss of vision in myopic eyes, with evidence of recent CNV outside the fovea. Treated eyes, however, retained a useful central vision more frequently than did observed eyes.
