The term choroidal neovascularization (CNV) denotes the growth of new blood vessels from the choroid into the subretinal space. The vessels may lie between the choroid and the retinal pigment epithelium (RPE) or between the native RPE and the sensory retina .The major importance of CNV is that it is the determinant of the disciform process, which ultimately results in cicatrization, disciform scar formation and loss of macular function.Many diseases were reported inducing abnormality at the level of the RPE-Bruch’s membrane-choriocapillaris complex and could be associated with CNV and a subsequent disciform scar formation, whereas several indications of an inflammatory reaction correlated to choroidal neovascularization (CNV) as in age-related macular degeneration (AMD) have been reported with elevated Titers of Chlamydia pneumoniae have been detected in some cases
