The conjunctiva is divided into the lid conjunctiva, bulbar conjunctiva and fornix conjunctiva. The bulbar conjunctiva usually clings to the lid and does not become lax, the fornix conjunctiva is the conjunctiva at the folds, and the bulbar conjunctiva is the clear membrane around the cornea on the surface of the eye. When there is laxity, it is seen externally as a membrane-like fold, mostly in the elderly, with similar skin laxity and muscle laxity. As we age, the conjunctiva also laxifies, and most patients have no obvious symptoms of self-conscious discomfort; when the conjunctiva is lax to a certain degree, functional tear overflow occurs. The patient’s subjective symptom is more tears, as the loose conjunctiva blocks the tear dots, allowing the tears that should normally drain to the tear dots and tear ducts to converge on the surface of the eye.
