    Abstract:
    BACKGROUND: During the last few years combined cataract and glaucoma surgery is an established method to control intraocular pressure (IOP) and visual rehabilitation in patients with cataract and glaucoma. Despite this, there are currently only few data concerning the results of combined surgery for primary open-angle glaucoma (POAG) and pseudoexfoliation glaucoma (PEXG). PATIENTS AND METHODS: To study the course of PEXG and POAG with respect to IOP regulation and visual acuity, 100 eyes with POAG (72 patients) and 22 with PEXG (19 patients) were evaluated which underwent a combined phacoemulsification and goniotrephination between 1993 and 1997. All patients had no glaucoma or other ocular surgery before. The mean follow up after operation was 39.5 (range 16 - 72) months. RESULTS: The mean preoperative IOP in PEXG (31.8 +/- 10.3 mm Hg) was significantly higher than in the POAG group (25.3 +/- 6.4 mm Hg) (p=0.0004). At follow up IOP decreased to 16.7 +/- 2.8 mm Hg (POAG) and 15.1 +/- 4.0 mm Hg (PEXG) (p < 0.0001). The absolute IOP lowering effect was significantly better for PEXG than for POAG (p=0.0003). All patients received medical treatment before surgery, whereas at follow up 59.0 % (POAG) and 81.8 % (PEXG) were untreated. The median preoperative visual acuity for the POAG was 0.32 (PEXG 0.25), visual outcome 0,63 (PEXG 0.5). CONCLUSION: The combined cataract and glaucoma surgery is a successful method of IOP control and visual rehabilitation. It seems that there is a tendency for a better efficiency and an untreated IOP regulation after surgery for PEXG. Thereby early surgical intervention could be an advantage for this glaucoma entity.
