46 Possible Causes for Bone Spicule-Like Pigmentation

  • Retinitis Pigmentosa

    Dilated funduscopy also showed bone spicule-like pigmented deposits, typical for retinitis pigmentosa.[ncbi.nlm.nih.gov] Funduscopic examination and fluorescein angiography revealed typical advanced RP changes with bone spicule-like pigment deposits in the posterior pole and the midperiphery[ncbi.nlm.nih.gov] Arteriolar narrowing, waxy palor of the disc, cystoid macular edema and bone spicule-like pigment changes are consistent with long-standing retinal and RPE degeneration in[institut-vision.org]

  • Retinitis pigmentosa 40

    spicule-like pigmentation of the fundus, and electroretinographic evidence of photoreceptor cell dysfunction System(s) affected: nervous Synonym(s): rod-cone dystrophy; retinal[unboundmedicine.com] The typical funduscopic findings of RP are present, including bone-spiculelike pigmentation, pallor of the optic discs, and narrowing of blood vessels ( A , E ).[iovs.arvojournals.org] Arteriolar narrowing, waxy palor of the disc, cystoid macular edema and bone spicule-like pigment changes are consistent with long-standing retinal and RPE degeneration in[institut-vision.org]

  • Leber Congenital Amaurosis 16

    Varying degrees of intraretinalpigment migration culminating in bone spicule-like pigment and gross pigmentclumps in the retinas were observed.[jamanetwork.com] They include: chorioretinal degeneration and atrophy centered about the fovea, “bone-spicule" like pigmentation, subretinal flecks, "marbled" fundus, pigmented nummular lesions[eyewiki.org] spicule-like pigmentation, and a significant prevalenceof keratoconus and cataract.[jamanetwork.com]

  • X-linked Intellectual Disability-Retinitis Pigmentosa Syndrome

    spicule-like pigmentation of the fundus, and electroretinographic evidence of photoreceptor cell dysfunction System(s) affected: nervous Synonym(s): rod-cone dystrophy; retinal[unboundmedicine.com] […] visual impairment; signs often seen in childhood, but severe vision problems do not develop until adulthood Characterized by poor night vision, constricted visual fields, bone[unboundmedicine.com]

  • Retinitis Pigmentosa 30

    spicule-like pigmentation of the fundus, and electroretinographic evidence of photoreceptor cell dysfunction System(s) affected: nervous Synonym(s): rod-cone dystrophy; retinal[unboundmedicine.com] […] nonrecordable a- and b-wave amplitudes on electroretinogram (ERG) testing, and ophthalmoscopic findings (ie, characteristic fundus changes in attenuated retinal vessels and bone-spicule-like[dovepress.com] Arteriolar narrowing, waxy palor of the disc, cystoid macular edema and bone spicule-like pigment changes are consistent with long-standing retinal and RPE degeneration in[institut-vision.org]

  • Usher Syndrome Type 1J

    Similar to other types of retinitis pigmentosa, fundus features include peripheral retinal atrophy with bone-spicule-like pigmentation, vascular attenuation, and waxy-pallor[webeye.ophth.uiowa.edu] These include pigment dispersion, which means that some parts appear lighter than others, followed by "bone spicules" which are jagged black spots which look like small fragments[dbproject.mn.org]

  • Retinitis Pigmentosa Type 4

    spicule-like pigmentation of the fundus, and electroretinographic evidence of photoreceptor cell dysfunction System(s) affected: nervous Synonym(s): rod-cone dystrophy; retinal[unboundmedicine.com] Arteriolar narrowing, waxy palor of the disc, cystoid macular edema and bone spicule-like pigment changes are consistent with long-standing retinal and RPE degeneration in[institut-vision.org] […] visual impairment; signs often seen in childhood, but severe vision problems do not develop until adulthood Characterized by poor night vision, constricted visual fields, bone[unboundmedicine.com]

  • Retinitis

    In the left eye, progressive bone-spicule-like pigment changes developed throughout the peripheral retina.[eyerounds.org] Arteriolar narrowing, waxy palor of the disc, cystoid macular edema and bone spicule-like pigment changes are consistent with long-standing retinal and RPE degeneration in[institut-vision.org]

  • Leber Congenital Amaurosis Type 9

    ) to more pronounced RPE atrophy with intraretinal bone spicule-like pigmentations and a preserved macular region as in RP.[molvis.org] bone spicule-like pigmentation and a preserved macular region.[wjgnet.com] In the remaining patients (Patients 5, 7, 8, 11, 14, 15, and 18) ranging in age from five to 39, RPE atrophy was more pronounced with bone spicule-like pigmentations.[molvis.org]

  • Cone Rod Dystrophy Type 16
