472 Possible Causes for Bone Spicules

  • Usher Syndrome Type 1K

    The fundoscopic finding of both eyes showed typical pigmentary degeneration with multiple bone spicule pigmentations in over the entire retina, attenuated retinal vessels,[mafiadoc.com] Temporal bone computed tomography and magnetic resonance imaging showed no specific findings.[mafiadoc.com] On ophthalmologic examinations, the lens and the cornea were intact, but the fundoscopic examination revealed bony spicule pigmentation with attenuated retinal vessels in[mafiadoc.com]

  • Nephronophthisis

    Bone spicule pigmentation can be seen in the periphery, the retinal vessels are attenuated, the ERG is undetectable, and there may be temporal pallor of the optic discs.[disorders.eyes.arizona.edu]

  • Usher Syndrome Type 3B

    These include pigment dispersion, which means that some parts appear lighter than others, followed by "bone spicules" which are little jagged spots.[boystownhospital.org] The optic nerve (arrow) looks very pale, the vessels (stars) are very thin and there is characteristic pigment, called bone spicules (double arrows).[medicinenet.com] […] of bone.[dbproject.mn.org]

  • Retinitis Pigmentosa with Situs Inversus

    Fundus examination showed bone spicule formation, pigmentation, arteriolar attenuation and optic atrophy in both eyes [Figure:1a].[ijo.in] Fundus examination reveals bone spicule pigment deposits, attenuated retinal vessels, retinal atrophy and waxy optic nerve pallor.[orpha.net]

  • Macular Degeneration, Early Onset

    No peripheral atrophy with bone spicule nor optic nerve atrophy were observed.[evrs.eu]

  • Bardet-Biedl Syndrome 2

    The fundus picture was an atypical retinitis pigmentosa with macular pigments previous to any bone spicules.[lup.lub.lu.se] There were salt-and-pepper changes in the midperiphery accompanied by bone spicule–like pigmentation.[jamanetwork.com] Early changes are more characteristic of atrophy with a paucity of pigment but later the bone spicule pattern of hyperpigmentation appears.[disorders.eyes.arizona.edu]

  • Retinitis Pigmentosa 7

    The macula looks smooth and normal; however, the retinal vessels are attenuated and there are bone spicules throughout the periphery. OS: Vertical C/D ratio is 0.0.[retinagallery.com] LCA is characterized by night blindness, constricted visual fields, narrowed vessels, bone-spicule pigmentation in midperiphery of retina, pigment deposits in macular region[cags.org.ae] Tags: bone spicules , Chihuly , fundoscopic image , glass , neural plasticity , neural remodeling , pigmented bone spicules , retina , retinal plasticity , retinal remodeling[prometheus.med.utah.edu]

  • Extraskeletal Myxoid Chondrosarcoma

    (SKB) Clear cells, giant cells and bone spicules. (SKB) The lesion also had areas of more conventional chondrosarcoma.[librepathology.org] (SKB) Clear cells, giant cells and bone spicules. (SKB) Somewhat hemangiopericytomatous vascular pattern with giant cells.[librepathology.org] […] matrix Areas with osteoclast-type giant cells mixed with small trabeculae of reactive bone May contain conventional low-grade chondrosarcoma May have secondary aneurysmal bone[librepathology.org]

  • Retinal Macular Dystrophy Type 2

    The classic fundus appears with dark pigmentary clumps in the periphery and perivenous areas (bone spicules).[atlasrleye.com] Fundus findings range from a salt and pepper appearance to frank bone spicules, and macular changes with foveomacular hyperfluorescence on fluorescein angiography.[atlasrleye.com] At later stages, the fundus picture discloses a pale optic disc, peripheral bone spicule-like hyperpigmentation and generalized atrophic changes of the peripheral retina.[atlasrleye.com]

  • Gordon Holmes Syndrome

    spicules.[disorders.eyes.arizona.edu] Clinical Characteristics Ocular Features: The retinal pigment epithelium changes may be seen as early as the first decade of life with pigment deposition resembling bone spicules[disorders.eyes.arizona.edu] Hypogonadism Clinical Characteristics Ocular Features: The retinal pigment epithelium changes may be seen as early as the first decade of life with pigment deposition resembling bone[disorders.eyes.arizona.edu]
