Can vasculitis affect eyesight?
Vasculitis can disrupt the blood supply to nerves around the eye which supply the muscles that move the eye (the third nerve, the fourth nerve and the sixth cranial nerves). Damage to any of these nerves usually results in double vision.
Is retinal vasculitis serious?
Retinal vasculitis is a sight-threatening inflammatory eye condition that involves the retinal vessels. It may occur as an isolated idiopathic condition, as a complication of infective or neoplastic disorders, or in association with systemic inflammatory disease1 [Table 1].
Can you go blind from vasculitis?
Vasculitis involving the eye typically is a result of inflammation of the tiny blood vessels of the retina (retinal vasculitis). Retinal vasculitis ranges in severity from mild to severe. Damage to the blood vessels of the retina can cause partial or complete blindness.
What are cotton wool spots?
Cotton-wool spots (CWSs) are common retinal manifestations of many diseases including diabetes mellitus, systemic hypertension, and acquired immunodeficiency syndrome. Clinically they appear as whitish, fluffy patches on the retina and eventually fade with time.
What causes vasculitis in the eye?
Diseases which cause retinal vasculitis include Behcet’s disease, systemic lupus erythematosus, antiphospholipid antibody syndrome, systemic necrotizing vasculitis, Wegener’s granulomatosus, Takayasu’s vasculitis, and Giant Cell arteritis.
Are cotton wool spots serious?
Cotton-wool spots are tiny white areas on the retina, the layer of light-sensing cells lining the back of the eye. Caused by a lack of blood flow to the small retinal blood vessels, they usually disappear without treatment and do not threaten vision. They can, however, be an indication of a serious medical condition.
What are cotton wool spots caused by?
Cotton wool spots are believed to occur secondary to ischemia from retinal arteriole obstruction. It is thought to represent nerve fiber layer infarct and pre-capillary arteriolar occlusion.
What causes retinal cotton wool spots?
Cotton wool spots are an abnormal finding on funduscopic exam of the retina of the eye. They appear as fluffy white patches on the retina. They are caused by damage to nerve fibers and are a result of accumulations of axoplasmic material within the nerve fiber layer.
Are cotton wool spots permanent?
Each cotton wool spot lesion leaves a permanent retinal defect. The destruction of the ganglion cell layer and nerve fiber layer will lead to a small focal defect in the area of the cotton wool spot as well as a more diffuse defect in retinal sensitivity due to the permanent damage to the nerve fiber layer.
Can cotton wool spots be treated?
Abundant cotton wool spots are seen in Malignant hypertension. Diabetes and hypertension are the two most common diseases that cause these spots, and the best treatment would be to treat the underlying disease.
