What does cotton wool bodies 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.

What disorders can cause cotton-wool spots on the retina?

Ischemic disorders that can result in cotton-wool spots include retinal vascular occlusions, ocular ischemic syndrome and severe anemia.

How 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.

What are cotton-wool spots in eyes?

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.

Are cotton wool spots normal?

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 exudates?

Cotton-wool spots are often referred to using the misnomer “soft exudates” and are described as slightly elevated, small, yellow-white or gray-white, cloud-like, linear or serpentine lesions with fimbriated borders in the superficial retina (Fig. 51.13).

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 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 does a cotton wool spot look like?

On ophthalmic fundus exam, cotton wool spots may appear as small, yellow-white (or grayish-white), slightly elevated lesions, which look like clouds with a fimbriate border in the superficial retina. Usually they are less than 1/3 disc areas in diameter, and are commonly found in the posterior pole of the fundus.

What’s the difference between cotton wool spots and exudates?

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 a disease of the retina cause visual symptoms?

Retinal diseases vary widely, but most of them cause visual symptoms. Retinal diseases can affect any part of your retina, a thin layer of tissue on the inside back wall of your eye.

What are the different types of retinal diseases?

Common retinal diseases and conditions include: 1 Retinal tear. A retinal tear occurs when the clear, gel-like substance in the center of your eye… 2 Retinal detachment. A retinal detachment is defined by the presence of fluid under the retina… 3 Diabetic retinopathy. If you have diabetes, the tiny blood vessels (capillaries)…

Can a untreated retinal disease cause blindness?

Untreated, some retinal diseases can cause severe vision loss or blindness. Many retinal diseases share some common signs and symptoms. These may include: You may need to try looking with each eye alone to notice these. It’s important to pay attention to any changes in your vision and find care quickly.

Where are the nerve cells located in the retina?

Retinal diseases vary widely, but most of them cause visual symptoms. Retinal diseases can affect any part of your retina, a thin layer of tissue on the inside back wall of your eye. The retina contains millions of light-sensitive cells (rods and cones) and other nerve cells that receive and organize visual information.
