Foveal hypoplasia (FVH) is characterized by absence or abnormal foveomacular reflex, unclear definition of the foveomacular area, and presence of capillaries running abnormally close to the macula. It can be isolated or associated with presenile cataract. The mutations in the PAX6 gene have been described in foveal hypoplasia. Recently, it has been reported that recessive mutations in SLC38A8 cause foveal hypoplasia.
