Blisters on the eyeball are commonly caused by localized lymphatic circulation disorders, conjunctivitis, conjunctival cysts, and rubbing of the eye.
1. When the lymphatic circulation of the bulbar conjunctiva is not smooth, it may lead to small blisters on the bulbar conjunctiva.
2. Stimulation of local inflammation of the eye, such as: conjunctivitis, keratitis, etc. may lead to edema of the bulbar conjunctiva, which appears to be a blister on the eyeball externally.
3. Conjunctival lymphatic obstruction leads to the accumulation of lymphatic fluid and the formation of cysts, which appear to be blisters on the eyeball.
4. Rubbing the eye with the hand may cause edema of the bulbar conjunctiva, which may appear as blisters on the outer surface of the eyeball.
It is recommended that the patient seek medical attention in a timely manner to determine the cause based on the results of the examination.
