What do cotton wool spots indicate?
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.
Do cotton wool spots obscure vessels?
Cotton wool spots appear on fundoscopy as white, fluffy lesions with hazy or feathered edges in the superficial retina. Underlying retinal vessels may be obscured.
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.
Can lupus cause cotton wool spots?
Mild lupus retinopathy consists of cotton–wool spots, perivascular hard exudates, retinal hemorrhages, and vascular tortuosity [7]. Moderate lupus retinopathy has focal or generalized arteriolar constriction and venous tortuosity.
Are cotton-wool spots serious?
Disease entity In otherwise healthy patients, the observance of a cotton wool spot (CWS) is not considered normal. A single cotton wool spot in one eye can be the earliest ophthalmoscopic finding in diabetic or hypertensive retinopathy.
Are cotton-wool spots common?
Finally, idiopathic causes of cotton-wool spots have been described, but these cases are rare and always a diagnosis of exclusion. Fortunately for the clinician, most patients who present with cotton-wool spots have other systemic or ocular findings that help narrow down their specific etiology.
Are cotton-wool spots normal?
In otherwise healthy patients, the observance of a cotton wool spot (CWS) is not considered normal. A single cotton wool spot in one eye can be the earliest ophthalmoscopic finding in diabetic or hypertensive retinopathy.
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 an eye exam detect lupus?
Regular comprehensive ocular examinations are important for early detection of ocular complications associated with SLE. By being aware of the systemic and ocular manifestations of SLE, optometric physicians can provide better care for their patients with lupus.
Do cotton-wool spots affect vision?
Cotton-wool spots (CWS) (Figure) are acute signs of vascular insufficiency to an area of retina. They have been described in many conditions, but only occasionally cause symptoms in patients. The most common symptoms associated with retinal CWS can include scotoma, arcuate defects, blurred vision, and amaurosis fugax.
Are cotton-wool spots Microaneurysms?
cotton-wool spots or ‘soft exudates’ either totally isolated or associated with fewer than 10 microaneurysms. These observations suggest that cotton-wool spots may be an early finding in diabetic retinopathy.
What kind of lesion is a cotton wool spot?
HIV, human immunodeficiency virus. A cotton-wool spot, or soft exudate, is a yellow-white lesion in the superficial retina that usually occupies an area less than one fourth that of the optic disc ( Fig. 69-19 ). A cotton-wool spot can occur singly or in conjunction with many others ( Fig. 69-20 ).
What causes cotton wool spots on chest X-ray?
Cotton – wool spots, or cytoid bodies, are not exudates, but rather are retinal infarcts. Hypertensive optic neuropathy is a late finding. [ncbi.nlm.nih.gov] An ECG may show some abnormalities that may be suggestive of right heart failure. Chest x – ray may also show enlargement of the chambers of the right heart. [medicinenet.com]
Can a cotton wool spot cause vision loss?
Cotton wool spots in general are visually asymptomatic, however, a patient may present with vision loss if the fovea is involved 13). Systemic symptoms of the underlying cause may be present. Diagnosis is usually achieved by a complete ocular examination, including a detailed dilated fundus exam.
How to diagnose cotton wool in the retina?
Fluorescein angiography can be particularly helpful in identifying some of these changes as well as small macular branch retinal vascular occlusions. A truly isolated cotton-wool spot in an otherwise healthy patient requires further investigation before ascribing it to idiopathic causes.
