Blistering of the patient’s eyes may be caused by vesicular conjunctivitis, conjunctival lymphatic obstruction, and herpes zoster infection. 1. Vesicular conjunctivitis: when human microbial proteins come into contact with the tissues of the conjunctiva, an allergic reaction can occur. This allergic reaction will combine with immunoglobulin through the cells of the skin and conjunctiva, leading to the release of histamine from the mast cells, which will lead to swelling of the local small blood vessels, redness, swelling, itchiness and other symptoms, and ultimately lead to blistering of the eyes of the patient. 2. Conjunctival lymphatic vessel blockage: As there are a large number of lymphatic vessels in the conjunctival tissue, when the lymphatic vessels are blocked, it will cause the lymphatic fluid in the conjunctival tissue to stagnate, resulting in the appearance of small blisters on the surface of the patient’s eyes. 3. Herpes zoster infection: If the patient is infected with herpes zoster infection, blisters may appear on the eyelids of the patient, and may be accompanied by eye pain and other uncomfortable symptoms. It is recommended that patients with eye blisters and other discomforts consult a doctor to evaluate their condition and follow the doctor’s instructions for treatment.
