Swollen eyes should be promoted by cold compresses to reduce the swelling. Oedema of the eyes is caused by various factors such as inflammatory stimuli, allergic factors, prolonged low hanging position of the eyes or the effect of systemic diseases on the eyelids, such as water and sodium retention due to chronic heart failure and renal insufficiency, which causes a large amount of fluid to accumulate in the soft tissue spaces under the skin of the eyes, resulting in eyelid swelling. The contraction of the subcutaneous myofibrillar tissue increases the intertissue fluid pressure, which facilitates the return of fluid to the veins and accelerates the reduction of ocular edema. Cold compresses can promote the edema to subside, but can only temporarily improve the symptoms, must be targeted at the cause of eye edema treatment, eliminate the cause, in order to fundamentally eliminate the eye edema.
