The prevalence of choroidal nevi associated with choroidal neovascular membrane (CNV) is estimated to range between 0.58% and 8.6% [1]. The pathogenesis of CNV is not completely understood. Researchers have suggested that damage caused to the choroid capillaries above the nevi affects the overlying retinal pigment epithelium and triggers production of angiogenic factors that, in turn, cause the development of CNV [2,3]. Hypoxia and inflammation may be involved in the process. Data have been inconsistent with both theories [4].
