100 Possible Causes for Blurred Vision, Cotton Wool Spots, Night Blindness

  • Diabetic Retinopathy

    However, bleeding can reoccur and cause severely blurred vision.[web.archive.org] 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] A 39-year-old woman with typical retinitis pigmentosa (RP) for 9 years and a positive family history of night blindness was diagnosed with diabetes mellitus (DM).[ncbi.nlm.nih.gov]

  • Retinopathy

    A 57-year-old woman with systemic lupus erythematosus (SLE) complaining of blurred vision in both eyes was diagnosed with bilateral HCQ retinopathy and CMO based on characteristic[ncbi.nlm.nih.gov] An ocular examination revealed multiple retinal cotton-wool spots and hard exudates. Interferon treatment was suspended.[ncbi.nlm.nih.gov] The short duration and rapid progression of symptoms along with the lack of family history of night blindness prompted a diagnosis of autoimmune retinopathy (AIR).[ncbi.nlm.nih.gov]

  • Branch Retinal Vein Occlusion

    Case report of a 60-year-old woman who complained of fever, chills, headache, lymphadenopathy, and blurred vision in the right eye following an insect bite to the lower right[ncbi.nlm.nih.gov] PURPOSE: To describe and follow cotton wool spots (CWS) in branch retinal vein occlusion (BRVO) using multimodal imaging.[ncbi.nlm.nih.gov] Abstract The ocular clinicopathologic features of this unique patient were congenital stationary night blindness, drusen of the optic nerve head, cilioretinal artery, intraretinal[ncbi.nlm.nih.gov]

  • Retinitis

    A second HIV negative patient presented with blurred vision and lid swelling and was found to have peripheral VZV retinitis confirmed by PCR.[ncbi.nlm.nih.gov] Very early CMV may resemble cotton wool spots, but with lesions larger than 750 µm, CMV must be considered.[eyewiki.aao.org] In young patients with the symptom of night blindness, it is important to differentiate retinitis pigmentosa from stationary night blindness.[ommbid.mhmedical.com]

  • Ocular Toxoplasmosis

    Suddenly blurred vision, floater, and pain could be caused by Toxoplasma gondii. Flashing, may necessitate a more precise peripheral fundus examination.[ncbi.nlm.nih.gov] The most common complaint of the patient is that of night blindness, followed by peripheral visual field loss. The patient had the typical features of RP.[egyptretinaj.com] KEYWORDS: Toxoplasma gondii; blurred vision; diagnosis; ocular toxoplasmosis; retinal scar; treatment[ncbi.nlm.nih.gov]

  • Cytomegalovirus Retinitis

    Patients receiving immunosuppressive therapy should be monitored for blurred vision, floaters, or visual loss and referred for urgent assessment to ensure accurate diagnosis[ncbi.nlm.nih.gov] The patient was found to have an exudative retinal detachment involving the fovea, subretinal hemorrhage, cotton wool spots, and active CMV retinitis temporal to the exudative[ncbi.nlm.nih.gov] Generally night precedes tunnel vision by years or even decades.

  • Acute Hypertensive Retinopathy

    A 34-year-old woman presented with a short history of headache and blurred vision.[nejm.org] Image in 2012: Three years later, the cotton-wool spot completely vanished.[atlasophthalmology.net] Destruction of the peripheral retina with laser (panphotocoagulation) decreases the neovascularization but also results in night blindness and constriction of the visual field[neuro-ophthalmology.stanford.edu]

  • Idiopathic Intracranial Hypertension

    Other symptoms include visual changes (blurred vision, transient visual obscurations, double vision).[racgp.org.au] Cotton wool spots were present in 4% of subjects, exudates in 3% and pseudodrusen in 4%.[ncbi.nlm.nih.gov] Vision problems : Blurry vision, double-vision, blind spot, loss of peripheral vision, progressive vision loss, blindness.[schmidtlaw.com]

  • Vasculitis

    Eyes may be red, itchy and burning, increased sensitivity to light, blurred vision.[allergy.org.au] Additional ophthalmic manifestations include isolated cotton-wool spots, cranial-nerve palsies, ocular hypotony, and pupillary abnormalities. 2 To detect these conditions,[dx.doi.org] Eye inflammation and blurred vision are also symptomatic, and in very severe cases blindness can occur.[rarediseases.org]
