Retinal–choroidal anastomosis is an exclusive clinical finding of macular neovascularization Type 3 in eyes with neovascular age-related macular degeneration. Multifocal macular neovascularization Type 3 is usually bilateral, and the lesions develop simultaneously, but when the multifocal phenotype is unilateral, it appears before the development of the unifocal one in the contralateral eye.
