Abstract.

Background: There are different surgical approaches for cataract and concomitant primary open-angle glaucoma (POAG). In a retrospective study we examined the long-term results of cataract extraction combined with trabeculotomy. Patients and methods: Between1990 and 1997, 194 eyes with cataract and POAG were operated on in a combined manner. Eighty-eight eyes received a trabeculotomy (TT), in 82 eyes a trabeculectomy was added to the trabeculotomy (TT+TE) and in 24 eyes, in which probing of Schlemm's canal was impossible, standard trabeculectomy (TE) was performed. Pre- and postoperative intraocular pressure (IOP), glaucoma medication, and the intra- and postoperative complications of all patients were analyzed. Results: Hyphema was the most common complication in the TT group (20.5%). Fibrin reaction occurred in 27.8% of all cases. There was no statistically significant difference in postoperative IOP between the TT group and the TT+TE group. A statistically significant decrease in IOP compared to preoperatively lasted 60 months in the TT group. In eyes with a preoperative IOP ≤20 mmHg, none of the three procedures reduced IOP significantly (<20% of the preoperative IOP). In the first 2 years after operation 50% of the patients had no need for antiglaucomatous medication. Conclusions: Cataract surgery combined with TT resulted in few complications. In low-tension glaucoma the combination with TT is not sufficient to decrease the IOP. In patients with higher preoperative IOP, however, cataract surgery combined with TT could be – on the basis of a postoperative observation time of 72 months – a suitable method for lowering the IOP sufficiently. Furthermore, the use of antiglaucomatous substances was reduced by this combined procedure.
