The condition is often seen in blepharitis, a chronic inflammatory disease involving the lid margin, eyelashes, and glandular tissue, and can be classified as scaly blepharitis, ulcerative blepharitis, canthal blepharitis, and so on. The symptoms are usually congestion of the lid margin, flushing, loss of eyelashes, punctate ulcers, increased discharge, etc., so it may manifest as a rotten eye. This condition is caused by the presence of irritating factors around the eyes or by unreasonable eye habits, long-term use of poor quality cosmetics, etc., so it is important to avoid these conditions. For the treatment of the disease, you can use saline or boric acid lotion locally to clean the lid margin, and in addition, you should apply antibiotic eye ointment to avoid aggravating the infection.
