Progress of research on tear change and treatment in conjunctivochalasis

Conjunctivochalasis is a common age-related ocular surface change. The loose conjunctiva accumulates between the eyelid, causing changes of tear secretion, excretion and tear components, leading to tear film instability and incomplete tear river. Dry and blurred symptoms appear. The visual quality and life quality reduced. The current treatments include local eye drops, traditional Chinese medicine and surgery. The common used surgical methods include crescent-shaped resection, conjunctival suture fixation, bipolar coagulation, lower eyelid tension reducing and so on. These methods improve patients' lacrimal symptoms and signs in varying degrees.
