Glaucoma due to penetrating keratoplasty

Secondary glaucoma after penetrating keratoplasty is a common serious complication. Elevated intraocular pressure, on the one hand, damages the function of corneal graft endothelial cells, which is one of the main reasons behind corneal graft failure after graft rejection, on the other hand, it also causes irreversible damage to the optic nerve, which ultimately leads to visual function. Lost. With the development of ophthalmic microsurgery technology and immunopharmaceutical research, the indications for corneal transplantation continue to expand. Although the incidence of early postoperative glaucoma related to wound leakage and graft adhesion has decreased, the lesions in the anterior segment of the eye are increasing The more complex, secondary glaucoma remains a common serious complication after surgery.
