Benign concentric annular macular dystrophy (BCAMD) is a progressive autosomal dominant macular dystrophy characterized by parafoveal hypopigmentation followed by a retinitis pigmentosa-like phenotype (nyctalopia and peripheral vision loss) with a bull's eye configuration.	Is a	True	Hereditary macular dystrophy	Inferred relationship	Some
A rare ectodermal dysplasia syndrome characterized by the association of ectodermal dysplasia (with hypotrichosis affecting scalp hair, eyebrows, and eyelashes, and partial anodontia), ectrodactyly, and macular dystrophy (appearing as a central geographic atrophy of the retinal pigment epithelium and choriocapillary layer of the macular area with coarse hyperpigmentations and sparing of the larger choroidal vessels). Variable additional limb defects (including absence deformities, polydactyly, syndactyly, or camptodactyly) have also been described, the hands often being more severely affected than the feet.	Is a	True	Hereditary macular dystrophy	Inferred relationship	Some
A rare and severe inborn metabolic disease characterized clinically by the association of severe-to-profound neurodevelopmental impairment, severe visual impairment, ante-postnatal growth impairment, severe scoliosis and, frequently, early-onset epilepsy.	Is a	True	Hereditary macular dystrophy	Inferred relationship	Some
Retinal macular dystrophy type 2 is a rare, genetic macular dystrophy disorder characterized by slowly progressive bull eye maculopathy associated, in most cases, with mild decrease in visual acuity and central scotomata. Usually, only the central retina is involved, however some cases of more widespread rod and cone anomalies have been reported. Rare additional features include empty sella turcica, impaired olfaction, renal infections, hematuria and recurrent miscarriages.	Is a	True	Hereditary macular dystrophy	Inferred relationship	Some
Occult macular dystrophy is a rare, genetic retinal dystrophy disease characterized by bilateral progressive decline of visual acuity, due to retinal dysfunction confined only to the macula, associated with normal fundus and fluorescein angiograms and severly attenuated focal macular and multifocal electroretinograms.	Is a	True	Hereditary macular dystrophy	Inferred relationship	Some
A rare, genetic retinal disease characterized by the characteristic dried-out soil fundus pattern due to diffuse deep white lines in the macula, to the level of the retinal pigment epithelium, which is slightly elevated and rippled. Macular exudation may be associated, and Bruch's membrane may be affected too. Occasionally, peripheral nummular pigmentary changes may be observed, associated with blindness. The lesions enlarge with time, with a preferential macular extension and confluence. Complications may include polypoidal choroidal vasculopathy, choroidal neovascularization or atrophic fibrous macular scarring that can lead to reduced visual acuity over time.	Is a	False	Hereditary macular dystrophy	Inferred relationship	Some
