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.

What are cotton wool spots in diabetic retinopathy?

Cotton-wool spots are nerve fiber layer infarctions from occlusion of precapillary arterioles. With the use of fluorescein angiography, there is no capillary perfusion. These are frequently bordered by microaneurysms and vascular hyperpermeability.

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.

Do cotton wool spots obscure vessels?

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 funds.
