Penetrating keratoplasty-induced glaucoma
Secondary glaucoma after penetrating keratoplasty is a common and serious complication. On the one hand, increased intraocular pressure damages the function of corneal graft endothelial cells, which is one of the main reasons for corneal transplant failure after graft rejection. On the other hand, it also causes irreversible damage to the optic nerve, ultimately leading to loss of visual function. With the development of ophthalmic microsurgery technology and immunotherapy research, the indications for keratoplasty are constantly expanding. Although the incidence of early postoperative glaucoma related to wound leakage and graft adhesion has decreased, the anterior segment lesions are becoming more and more complicated, and secondary glaucoma is still a common and serious complication after surgery.
