Abstract
Purpose :
The conventional trabeculectomy still remains the most frequently performed glaucoma surgery. However, this standard surgical procedure is often accompanied by complications. Our goal was to compare retrospectively, the efficacy and safety of a modified filtering trabeculotomy, designed at the University Hospital of Würzburg with a conventional trabeculectomy in open angle glaucoma patients.
Methods :
We conducted a retrospective study of 188 patients with open angle glaucoma, who underwent either modified filtering trabeculotomy (101) or conventional trabeculectomy (87) in the years 2007-2014. Main outcome measures were visual acuity, intraocular pressure, complications, antiglaucomatous medication, subsequent surgeries, complete success and relative success according to the World Glaucoma Association.
Results :
There were no significant differences between two examined groups noted in the age (p=0,41), gender (p=0,06), best corrected visual acuity (logMAR) (p=0,79), intraocular pressure (p=0,12), side (p=0,07), type of open angle glaucoma (p=0,05), number of pseudophakic eyes (p=0,22) prior to the operation. The ‘complete success’ was in the both group statistically equal (p=0,84). This study found no difference between the groups in complications such as choroidal detachment, bleb-leakage or requirement for lens surgery (p=0,05), (p=0,26), (p=0,26) respectively.
Conclusions :
Both surgical procedures are equally effective in terms of reducing intraocular pressure. Both operation techniques have equal rates of postoperative complications.
