Pigmentary retinopathy Spicular pigmentation of the retina HP:0007823 Fundus with peripheral bony spicules Pigment migration into the retina in a bone-spicule configuration (resembling the nucleated cells within the lacuna of bone). HP:0007644 Retinal pigmented bone spicules Bone spicule pigmentation of the retina HP:0007683 UMLS:C1836926 Bone corpuscle fundus pigmentation Retinal 'bone corpuscle' pigmentation Spicular pigmentation of the retina is typically associated with migration of microglia or retinal pigment epithelial cells into the neuroretina secondary to photoreceptor cell death; melanin from these cells causes the pigmentary changes.
