The folds observed above the white of the eye are due to a clear layer of tissue called the conjunctiva that covers the top of the eye. This fold is formed due to the conjunctiva and not due to the structure of the wall of the eye. In a normal eye above the conjunctiva, which is in the inner canthus of the eye, there will be a normal fold of the conjunctiva in this area due to the compression of the surrounding tissues, a structure called the semilunar fold of the conjunctiva. The semilunar fold on the human eye is equivalent to the third eyelid in lower animals, which emerged with degeneration during evolution and is part of the normal eye structure. There is another condition that causes the conjunctiva to develop folds elsewhere. In the event of an acute inflammatory reaction in the conjunctiva, this can cause the conjunctiva to become congested and edematous, and the edema can cause folds to appear in other areas of the conjunctiva as well, and if this is the case the conjunctival folds suggest an inflammatory reaction. The inflammatory reaction will need to be treated with appropriate medication and the folds will subside after the edema of the conjunctiva has subsided.
