428 Possible Causes for Pigment Clumping, Retinal Pigmentation

  • Retinal Pigmentary Dystrophy

    […] of the retinal pigment epithelium/photoreceptor complex.[ncbi.nlm.nih.gov] Group of inherited abnormalities in the retina; characterized by night blindness, retinal atrophy, weakening of the retinal vessels, pigment clumping, and contraction of the[icd10data.com] Top: Color fundus photos demonstrate pigment clumping OU, ERM OD, lamellar hole and faint ERM OS. Bottom: Images have been magnified to show macular pigment clumping.[webeye.ophth.uiowa.edu]

  • Pigmented Paravenous Retinochoroidal Atrophy

    Fluorescein angiography showed a window defect in the retinal pigment epithelium, with hyperfluorescence representative of retinal pigment epithelium and choriocapillaris[ncbi.nlm.nih.gov] A patient had bilateral macular coloboma with aggregations of pigment clumps located perivascularly, predominantly paravenously, and in other parts of the retina.[ncbi.nlm.nih.gov] Fluorescein angiography showed hyperfluorescence due to the pigment epithelial atrophy together with hypofluorescence corresponding to bone spicule pigment clumping.[ncbi.nlm.nih.gov]

  • Goldmann-Favre Syndrome

    Ophthalmoscopic examinations revealed peripheral retinoschisis in the superior temporal retina, diffusely abnormal retinal pigment epithelium, and lack of macular and foveal[ncbi.nlm.nih.gov] […] nummular pigment clumping and atrophy at level of RPE (Fig. 1e) 18 M 32 OD: 6/9 ND Constricted visual fields Left macular cysts OS: 6/9 Mid-peripheral nummular pigment clumping[iovs.arvojournals.org] Clinical Relevance The combination of night blindness, hyperopia, and clumped retinal pigment deposits should raise the suspicion that a patient has NR2E3 disease.[ncbi.nlm.nih.gov]

  • Sorsby's Fundus Dystrophy

    Progressive retinal pigment epithelial atrophy and peripheral pigment clumping occurred in elderly relatives who lost ambulatory vision.[ncbi.nlm.nih.gov] To address this question we established human retinal pigment epithelial cell lines expressing wild type or S156C (Ser(156) changed to cysteine) mutant TIMP-3.[ncbi.nlm.nih.gov] pigment epithelial (RPE) cells.[ncbi.nlm.nih.gov]

  • Central Areolar Choroidal Dystrophy

    Interindividual phenotypic variability was apparent and ranged from predominantly drusenlike depositions to single perifoveal pigment clumps.[ncbi.nlm.nih.gov] Early in the course of the dystrophy, there is fine, symmetric mottling of the retinal pigment epithelium in the macula, often in a bull's-eye pattern.[ncbi.nlm.nih.gov] The presence of drusen and pigment clumping was determined with color fundus photography. High-resolution in vivo imaging was performed with cSLO and SD-OCT.[ncbi.nlm.nih.gov]

  • Retinitis Pigmentosa

  • Adult-Onset Foveomacular Vitelliform Dystrophy

    CONCLUSIONS: In light of previous histopathological studies, the central nonfluorescent spot may be interpreted as a masking effect of a pigment clump, whereas the hyper-fluorescent[ncbi.nlm.nih.gov] The purpose of the study was to report aperture of retinal pigment epithelium (RPE) as a late complication and an unreported finding during the natural course of adult-onset[ncbi.nlm.nih.gov] The hyperreflective line corresponding to the photoreceptor layer was elevated by the material and separated from the retinal pigment epithelium layer.[ncbi.nlm.nih.gov]

  • Retinal Telangiectasia

    There have been only two reports of retinal pigmentation abnormalities and a single case of bilateral macular deposits in KMS, but this is the first report of a Coats type[ncbi.nlm.nih.gov] Pigment clumps with a whitish discoloration are seen to the right of the macular center.[eyecenters.com] SRNV on SD-OCT was defined as the presence of thickening of the retinal pigment epithelium-choriocapillaris complex with or without intraretinal fluid or subretinal fluid[ncbi.nlm.nih.gov]

  • North Carolina Macular Dystrophy

    Adjacent to the central lesion, some lipofuscin was identified in the retinal pigment epithelium.[ncbi.nlm.nih.gov] F igure 2. ( A ) Patient IV:5: fundus photograph showing bilateral macular RPE atrophy and pigment clumping, with surrounding drusen-like deposits and ( B ) fundus AF imaging[iovs.arvojournals.org] Adjacent to the macular lesion, some lipofuscin was identified in the retinal pigment epithelium.[ncbi.nlm.nih.gov]
