Glaucoma filtration surgery is currently the preferred method for patients in whom anti-glaucoma medication and laser treatment can not control intraocular pressure, and its postoperative filtering bleb scar formation is the leading cause of surgical failure. At present, there are some progresses in the basic and clinical studies of postoperative anti-glaucoma scar.
