Abnormal retinal morphology Abnormal retinal pigmentation HP:0007703 HP:0007743 Any deviation from the normal pigmentation of the retina. Abnormality of RPE Abnormality of retinal pigment epithelium SNOMEDCT_US:421689001 Retinal pigmentary anomaly UMLS:C1862475 UMLS:C1720508 HP:0008051 Abnormality of the retinal pigment epithelium Abnormality of retinal pigmentation This includes abnormalities of the pigmentation of the RPE and intraretinal pigment migration. An abnormality of the retina characterized by pigment deposition. It is typically associated with migration and proliferation of macrophages or retinal pigment epithelial cells into the neuroretina; melanin from these cells causes the pigmentary changes. Pigmentary retinopathy is a common final pathway of many retinal conditions and is often associated with visual loss. HP:0007741
