PURPOSE: To elucidate the characterization of intraocular pressure (IOP) spike after trabeculotomy, and after the combined procedure of phacoemulsification and aspiration (PEA) and intraocular lens (IOL) implantation. METHODS: Included in this study were 39 patients (53 eyes) with primary open-angle glaucoma with IOPs uncontrolled even with anti-glaucoma medication. We conducted a retrospective study for the following two groups: Patients who underwent trabeculotomy alone (25 eyes) and patients undergoing trabeculotomy combined with PEA and implantation of an IOL (28 eyes). RESULTS: In 7 (28%) of the 25 eyes after trabeculotomy alone and 7 (25%) of the 28 eyes after the combined procedure, transient IOP elevation was found postoperatively. The incidence of hyphema-related IOP spike was significantly higher in eyes after trabeculotomy alone (16%) than after the combined procedure (0%). After removal of the blood present in the anterior chamber in eyes with hyphema-related IOP spikes, the IOP levels were well controlled. CONCLUSIONS: Hyphema-related IOP spike is one of the common complications in eyes after trabeculotomy alone, and the combined procedure decreases the incidence of this complication. It is thought that removal of prolonged massive hyphema is effective as treatment for hyphema-related IOP spike.
