Allergic blepharitis symptoms?

Eyelid edge hyperemia, eyelashes and eyelid edge surface attached to epithelial scales, eyelid edge surface can be a little sebum overflow, sebum gathered in the eyelashes root end, forming yellow wax secretion, dry scab, scales and scab skin removed, exposed the hyperemia of eyelid edge surface, but no ulcer and pus point, eyelashes easy to fall off, and can be reborn.

If the inflammation does not heal for a long time, it can lead to blepharoplasty, and the posterior lip is blunt and round, but can not be in close contact with the eyeball. If it is accompanied by conjunctivitis, there can be swelling and outward turnover of lacrimal dots, resulting in epiphora. The lower eyelid eczema caused by lacrimal overflow forces the patient to wipe tears frequently and make the lower eyelid ectropion, which aggravates lacrimal overflow.

The sebaceous glands on the eyelid edge secrete a lot of fat. After drying, they scab and bind the eyelashes into bundles. After the scab is removed, hemorrhagic ulcer and small abscess can be seen at the root of the eyelashes. Because the lesions are deep into sebaceous glands and hair follicles, the hair follicles are damaged, and the eyelashes are easy to fall off and not easy to regenerate, forming bald eyelashes, even if the regeneration position is not correct. Nearby scar contraction, the formation of trichiasis or eyelash disorder, stimulate the cornea; If the lesion is delayed for a long time, the eyelid margin will be thickened and deformed. Accompanied by chronic conjunctivitis, lacrimal overflow, eczema around the skin, and even lower eyelid ectropion, etc., leading to the aggravation of lacrimal overflow, tears and promote ectropion and chronic conjunctivitis.
