A layer of folds on the eyeball is usually related to the relaxation of the bulbar conjunctiva, ocular congestion and edema, conjunctival tumors or ocular trauma, and once detected, prompt medical treatment is needed. 1. Loose conjunctiva: Due to congenital developmental abnormality or aging, the conjunctiva may become loose, and then folds may appear with the movement of the eyeball. 2. Ocular congestion and edema: If you suffer from conjunctivitis or eyelid entropion or ectropion, etc., the conjunctiva may become congested and edematous, and the enlarged conjunctiva will be squeezed during the movement of the eyeballs, resulting in folds in the eyeballs. 3. Conjunctival tumor: it may lead to abnormal proliferation of the conjunctiva to increase its volume, and then be squeezed to cause the eyeball folds. 4. Eye trauma: If the eye is traumatized and the conjunctiva is lacerated, the conjunctiva may wrinkle together, resulting in a folded eyeball. If there is a layer of folds on the eyeball, it is important to consult a doctor as soon as possible to clarify the cause of the problem and follow the doctor’s instructions.
