Purpose: Trabeculectomy is a frequently used surgical procedure in open-angle glaucomas. The present study analyses the outcome and complications after trabeculectomy or re-trabeculectomy depending on the preoperative intraocular pressure (IOP) < 30 mmHg and >= 30 mmHg. Methods: One hundred and eighteen patients were included in this retrospective study. Primary ocular outcomes were the postoperative IOP at discharge and postoperative complications such as choroidal detachment and flattening of the anterior chamber. The necessity of postoperative interventions such as needle revisions, viscoelastic injections or surgical revision was documented. Results: In this survey 118 patients (68 men, 50 women) were included (age [arithmetic mean] 68.3 +/- 12.1 years). The postoperative follow-up period was 6-9 months. In 60 patients the preoperative IOP was < 30 mmHg, in 58 patients >= 30 mmHg. Postoperative complications were flattening of the anterior chamber (< 2 corneal thickness) in 11 patients (9.3%) and temporary choroidal detachment in 20 patients (16.9%). On the day of discharge the mean IOP was 9.8 mmHg. Hence the IOP was on average reduced by 17 mmHg (SD 11.2 mmHg). Postoperative interventions were necessary in 28 patients (23.7%). Seventeen (14.4%) developed tenon cysts which were treated by needle revision of the bleb. Nine patients (7.6%) underwent a viscoelastic injection for persistent hypotony and 10 patients underwent bleb revision (8.5%). Conclusions: This study does not show statistically significant differences depending on preoperative IOP in temporary choroidal detachment and postoperative interventions. A postoperative flattening of the anterior chamber was found statistically significantly more often in patients with higher preoperative IOP.
