title: [Visual outcome after trabeculectomy - a retrospective study].
abstract: BACKGROUND
  Trabeculectomy (TE) is the standard operation for glaucoma. An alternative interventional treatment of glaucoma is the cyclophotocoagulation (CPC). In a data analysis in 2012, a visual loss was found after transscleral CPC. The aim of this study was to investigate the outcome after TE.
  
  
  METHODS
  91 patients with pseudoexfoliation (n=38), open angle (n=22), normal tension (n=8), congenital (n=1) and secondary glaucoma (n=22) were included. The follow-up time was 24 months. Intraocular pressure (IOP), best corrected visual acuity (BCVA) and the total number of antiglaucoma drugs (AGD) were recorded.
  
  
  RESULTS
  The mean age was 68.18±12.12 years. Mean IOP reduction after 24 months was 14.76±10.62 mmHg (-49%, p<0.001). On average, 2.34±1.17 (-85%, p<0.001) AGDs could be reduced. A mean BCVA decrease of 0.15 logMAR (±0.26, p<0.001) was found.
  
  
  CONCLUSIONS
  TE is a successful method for lowering the IOD. However, postoperative visual loss is possible.
