The appearance of folds on the surface of the white eye is mostly seen in conjunctival disease. According to the different manifestations, it can be divided into the following conditions. First, conjunctival congestion with edema is most often seen in allergic conjunctivitis. For this disease, anti-allergy, symptomatic treatment and local cold compresses need to be given. Second, conjunctival laxity. This condition is most commonly seen in middle-aged and elderly people and can be seen as an abnormal accumulation of conjunctiva in the conjunctival sac, sometimes exposed outside the lid fissure, usually causing significant dryness and discomfort in the eye. Conjunctival circumcision may be considered to relieve the symptoms. Third, eye fatigue caused by excessive eye use. As long as reasonable rest is taken, the symptoms can usually improve on their own, but it is recommended that good eye habits must be maintained.
