We reviewed the longterm course of intraocular pressure (IOP) in 66 eyes of 53 glaucoma patients that underwent surgery for cataract and/or glaucoma. The series included primary open angle glaucoma 25 eyes, primary closed angle glaucoma 23, capsular glaucoma 7, traumatic glaucoma 4 and glaucoma secondary to iritis 7. In 34 eyes, extracapsular cataract extraction with intraocular lens implanta-tion (ECCE+IOL) was performed alone (group 1). Simultaneous surgery with (ECCE+IOL) and trabeculotomy was performed in 13 eyes (group 2). Simultaneous surgery with (ECCE+IOL) and trabeculectomy was performed in 19 eyes (group 3). When the postoperative course was evaluated by Kaplan-Meier life table analysis, the survival probabilities of IOP at 4 years were 0.55±0.16 for group 2 and 0.73±0.10 for group 3. There was no significant difference between the two groups. In group 1, the survival probability at 2 years was 0.94±0.06 for 17 eyes with closed angle glaucoma and 0.58±0.16 for 17 eyes with open angle glaucoma. The difference was significant (p<0.05). In group 3, the survival probability of filtering bleb was 0.31±0.12 at 2 years. The intraocular pressure was well-controlled even after disappear-ance of filtering bleb in several eyes.
