322 Possible Causes for Cotton Wool Spots

  • Preeclampsia

    This ischemic state can manifest as reduced arteriolar caliber and arteriovenous ratio, retinal haemorrhages, oedema and cotton wool spots secondary to arteriolar damage,[eyewiki.aao.org]

  • Diabetic Retinopathy

    The first signs of nonproliferative retinopathy are Capillary microaneurysms Dot and blot retinal hemorrhages Hard exudates Cotton-wool spots (soft exudates) Hard exudates[merckmanuals.com] spots.[ncbi.nlm.nih.gov] Key Points Features of diabetic retinopathy can include microaneurysms, intraretinal hemorrhage, exudates, cotton-wool spots, macular edema, macular ischemia, neovascularization[merckmanuals.com]

  • Hypertensive Crisis

    A dilated fundus examination showed improvement in hemorrhages and cotton-wool spots.[reviewofoptometry.com] Organ damage can include: Encephalopathy Grade III ( retinal haemorrhages, exudates, cotton wool spots and retinal oedema ) or Grade IV (papilloedema) retinopathy Renal failure[em3.org.uk] Grade 3 (white cotton wool spots, flame shaped hemorrhage and yellow white exudates) and grade 4 (papilledema along with hemorrhage and exudates) retina changes are cardinal[symptoma.com]

  • Multiple Myeloma

    Physical Examination On head, ears, eyes, nose, and throat (HEENT) examination, the eyes may show exudative macular detachment, retinal hemorrhage, or cotton-wool spots.[emedicine.medscape.com] Examination for MM may reveal the following: HEENT examination: Exudative macular detachment, retinal hemorrhage, or cotton-wool spots Dermatologic evaluation: Pallor from[emedicine.medscape.com]

  • Peripheral Vasoproliferative Retinopathy

    Cotton wool spots may also be seen in other systemic vasculitides, such as polyarteritis nodosa, temporal arteritis, or Wegener's granulomatosis.[ncbi.nlm.nih.gov] F/A: HF - blockage of background choroidal and retinal capillary fluorescence. 14. • Cotton wool Spots /Soft exudates/ NFL infarcts - Local ischaemia ,axoplasmic flow block[slideshare.net] cotton wool spots).[patient.info]

  • Retinopathy

    An ocular examination revealed multiple retinal cotton-wool spots and hard exudates. Interferon treatment was suspended.[ncbi.nlm.nih.gov] The first signs of nonproliferative retinopathy are Capillary microaneurysms Dot and blot retinal hemorrhages Hard exudates Cotton-wool spots (soft exudates) Hard exudates[merckmanuals.com] Cotton wool spots 2. Venous beading 3. Intraretinal microvascular abnormalities (IRMA) in at least 2 contiguous overlapping photographic fields 4.[bu.edu]

  • Central Retinal Vein Occlusion

    PURPOSE: To report a case series, whereby we encountered a transient increase in retinal cotton wool spots (CWS) following anti-vascular endothelial growth factor (anti-VEGF[ncbi.nlm.nih.gov] There were intraretinal hemorrhages and cotton-wool spots within the superior vascular arcade and nasal to the optic disc.[ncbi.nlm.nih.gov] Possible predictors included baseline VA, age, presence of cotton wool spots (CWS), haemorrhages (few scattered or multiple deep), foveal detachment, CRT, time from presentation[ncbi.nlm.nih.gov]

  • Branch Retinal Vein Occlusion

    PURPOSE: To describe and follow cotton wool spots (CWS) in branch retinal vein occlusion (BRVO) using multimodal imaging.[ncbi.nlm.nih.gov] Patients will have disc swelling and retinal neovascularization, and cotton wool spots.[decisionmakerplus.net] wool spot in his right macula (fig 1 ).[bmj.com]

  • Purtscher's Retinopathy

    The most-prevalent bilateral retinal signs include white ischemic infarcts (cotton-wool spots or Purtscher-flecken) and hemorrhages (dot and blot, pre-retinal, or flame).[ncbi.nlm.nih.gov] Cotton-wool spots in PR represent infarctions of the retinal nerve fiber layer.[ncbi.nlm.nih.gov] Purtscher described sudden blindness in patients with severe head trauma due to a remote retinopathy, characterised by bilateral retinal haemorrhages, cotton wool spots, and[ncbi.nlm.nih.gov]

  • Papilledema

    wool spots In chronic phase, optic disc elevation and blurred margins, but no hemorrhages or cotton wool spots In atrophic phase (optic nerve axons have died), optic disc[kellogg.umich.edu] wool spots and hard exudates may result in complete vision loss.[ncbi.nlm.nih.gov] The presence of exudates, cotton wool spots, or hemorrhages is rare in most conditions associated with optic disc swelling other than papilledema and the non-arteritic form[news-medical.net]
