Secondary glaucoma after penetrating keratoplasty

Abstract

OBJECTIVE: To investigate the etiology and management of secondary glaucoma after penetrating keratoplasty (PKP). METHODS: Eighty cases (80 eyes) with secondary glaucoma occurring in 1,450 cases (1,500 eyes) of PKP, its causes, time of onset and the relationship with the primary disease were analyzed. According to different causes, they were treated with different therapies. RESULTS: The intraocular pressure (IOP) of 63 cases (63 eyes) became normal after drug treatment for 2 - 3 weeks. In 17 cases (17 eyes) who had received antiglaucomatous operations, 13 cases' (13 eyes) IOPs were normal and 4 cases' (4 eyes) still high. CONCLUSIONS: Accurate perioperative management can decrease the incidence of secondary glaucoma after PKP. The majority of secondary glaucoma can be controlled by different therapies according to different causes.
