Conjunctiva appears gray-white membrane
Introduction
Introduction The gray-white membrane of the palpebral conjunctiva can be seen in various types of conjunctivitis, which is usually caused by infectious factors. Due to leakage, bleeding, and mechanization of the new blood vessels, scars are finally formed, forming a permanent mechanical film. Found in infectious conjunctivitis, membranous conjunctivitis, pseudomembranous conjunctivitis, epidemic keratoconjunctivitis and other infectious conjunctivitis. Conjunctivitis is mostly contagious, so it is advisable to wash hands, wash your face or wipe your hands without hands and sleeves. The washbasin, towel, handkerchief, etc. must be separated from others and should be boiled and disinfected frequently to prevent infection.

Red eye disease (infectious conjunctivitis): acute onset, conscious tearing, foreign body and burning sensation. Check eyelids, conjunctival edema, conjunctival hyperemia, purulent or mucous secretions, often make the upper and lower eyelashes stick together, and it is difficult to blink when getting up in the morning. In patients with severe bacterial red eye disease, the eyelids are red and swollen, and the sputum conjunctiva has an off-white membrane, which can be wiped off but easily regenerated, which is called pseudomembrane; the secretion of viral red eye disease is mostly watery or sticky, and there is a cold-like symptom, a small bleeding point under the bulbar conjunctiva. Accompanied by the same side of the ear lymph node enlargement, tenderness; allergic red eye disease secretions are thin, or mucin-like, filamentous, with obvious itching, eyelids, conjunctival edema, and often can find allergic causes.
Membrane conjunctivitis, also known as diphtheritic conjunctivitis, is acute suppurative conjunctivitis caused by diphtheria. It is characterized by a layer of gray-white membrane-like exudate that is not easily exfoliated on the surface of the conjunctiva, accompanied by symptoms of diphtheria, diphtheria, fever and other systemic poisoning. Due to the extensive vaccination of diphtheria vaccine, the disease is currently extremely rare in China.
Pseudomembrane conjunctivitis: severe acute conjunctivitis caused by some pathogens, a membranous exudation can form on the surface of the conjunctiva, which is formed by the condensation of proteins and cellulose exuded from the blood vessels on the surface of the conjunctiva. Membranous conjunctivitis, in fact, the formation of pseudomembrane is a manifestation of inflammatory response and is not specific. In addition to the general symptoms of acute conjunctivitis, the secretion of conjunctival sac is obviously increased, and the surface of the conjunctiva and the conjunctiva of the iliac crest is gray-white membranous exudation. The exudation membrane is generally easy to be peeled off. After peeling, the conjunctiva below it may have some bleeding, no obvious ulcer. A new pseudomembrane can be formed any more, and the exudation membrane is not easy to be peeled off in some serious cases. After the exfoliation, the wound surface is ulcerated and has more bleeding; generally, after 1 to 3 weeks, the pseudomembrane can gradually disappear. Since acute inflammation of multiple conjunctivitis can be accompanied by a pseudomembrane, diagnosis should be based on other clinical features, general conditions, and pathogens.
Diagnosis
Differential diagnosis
Differential diagnosis of leucorrhea in the palpebral conjunctiva:
1. The conjunctiva becomes shallow or pale: the conjunctiva becomes lighter or paler. When the anemia is different, the color of the conjunctiva becomes lighter or paler.
2, optic nerve head pale: clinically, the color of the nipple is light or pale is called optic atrophy, and strictly called optic atrophy refers to the degenerative lesion of the optic nerve, causing the color of the optic papilla to become pale or pale. Therefore, it should be determined from the color of the optic nipple and its function, that is, vision, field of vision, and the like.
3, the pupil turns white: China is a yellow species, the pupil is black, quiet and bright. If the color of the pupil is abnormal, it indicates that the disease has already occurred. The pupil area changes from black to white, the most common cause being senile cataract.
