periorbital ecchymosis
Introduction
Introduction The raccoon eye sign is called a panda or raccoon. It expresses blood stasis around the eyelids on both sides, that is, the cyanosis of the skin tissue around the eyes, and the bleeding of the capillaries under the skin may be accompanied by swelling, pain, and temporary visual blur. Systemic starch precipitation, platelet hypoplasia or intracranial hemorrhage can cause microvascular bleeding in the eyelids, causing pathological raccoon eyes; trauma such as eye sockets or eyelid contusions can also cause subcutaneous hemorrhage, and form black The appearance of the eye circles.
Cause
Cause
Systemic starch precipitation, platelet hypoplasia or intracranial hemorrhage can cause microvascular bleeding in the eyelids, causing pathological raccoon eyes; trauma such as eye sockets or eyelid contusions can also cause subcutaneous hemorrhage, and form black The appearance of the eye circles. Subcutaneous tissue has signs of bleeding, go to the hospital for a blood test to see if there is thrombocytopenia, there may be thrombocytopenia.

The microvascular venous bleeding in the eyelids forms the appearance of dark circles. Due to frequent staying up late, emotional instability, eye fatigue, aging, venous blood flow velocity is too slow, eye skin red blood cells are insufficient oxygen supply, excessive accumulation of carbon dioxide and metabolic waste in venous blood vessels, chronic hypoxia, blood stasis caused You can check the blood to see if there is any abnormality of the liver and kidney.
Diagnosis
Differential diagnosis
Periorbital ecchymosis needs to be distinguished from the following symptoms.
Congenitally inherited white form:
Congenitally inherited dark circles, so that patients suffer from their childhood, no matter whether the sleep is sufficient, the eyelids are not wrong. If it is a congenital type, the family will be a panda family. Not only will there be dark circles, but the color around the lips and wrinkles will be deeper. Under pathological biopsy, the pigmentation site is in the lower layer of the epidermis and the upper layer of the dermis, resulting in a long-term black-gray eye circle.
Such dark circles are usually associated with skin color typing. Those with darker skin such as type 4 to type 6 have this type of genetic dark circles; they are also related to race, such as Indians, Southeast Asians, or Residents, etc., have darker pigments around the eyes and deeper eyelids, thus forming deeper natural dark circles.
Vascular stagnation type of dark circles:
This is most common in the clinic because of poor circulation of the venous return in the eye socket or the face. The skin on the face is the thinnest skin of the human body. The dermis of the eyelids is covered with veins. If the blood circulation is not good, the blue-black tone of the veins will be reflected on the skin, making the face look darker; The upper blood vessels are swollen and swollen, causing shadows under the eyes and forming a panda eye with bubbles.
This type of dark circles is related to life, including staying up late, insomnia, emotional stress, crying, long-term improper use of eyesight, etc. Changes in estrogen, such as before women's menstruation, late pregnancy, etc., can also cause vascular swelling. In addition, there are long-term nasal diseases, such as allergic rhinitis, sinusitis, nasal congestion or nasal septum caused by nasal congestion, congestion, etc., because the venous return of the lower eye face is drained through the nasal veins, if the venous pressure becomes larger, The lower eyelid venous return will become worse, causing venous blood to stagnate and produce dark circles.
Pigmentation caused by skin diseases:
This is the post-inflammatory pigmentation caused by dermatitis of the eyelids. People with atopic physique are particularly prone to this condition because of atopic dermatitis of the eyelids and allergic rhinitis. Especially when the skin is dry, the eyelids are more dull and dull. Allergic contact dermatitis of the eyelids is also a common cause of pigmentation. Because the skin of the eyelids is thin, it is less tolerant to any skin care products or cosmetics than the general skin. In addition to the eye shadow and eye cream rubbed on the eyelids, facial cleanser, cream or nail polish (contact caused by eyelids), They are the culprit causing allergic contact dermatitis of the eyelids. Pigmentation caused by these chronic dermatitis is also a major factor in dark circles.
