title: [Intraocular pressure after filtering operation or combined filter-cataract operation].
abstract: BACKGROUND
  The prevalence of glaucoma is 2% and of cataract 25% in patients at the age of 65 to 75 years. To this moment the discussion is open about the optimal therapy when there is simultaneous cataract and glaucoma. We evaluated and compared the intraocular pressure and the visual acuity in patients with filtering-surgery and combined surgery (= filtering surgery plus simultaneous cataract surgery).
  
  
  METHODS
  In a retrospective study 56 eyes of 45 patients operated by filtering surgery and 46 eyes of 40 patients operated by combined surgery were examined.
  
  
  RESULTS
  Patients with combined surgery showed significant higher frequency of fibrin in the anterior chamber compared to patients with filtering-surgery. After 12 months there was no significant difference in intraocular pressure between both groups. The IOP of the last examination was 16 +/- 4 mm Hg in eyes with combined surgery and 14 +/- 4 mm Hg in eyes with filtering surgery. Eyes with combined surgery showed an increase of visual acuity from 0.2 +/- 0.2 to 0.4 +/- 0.3, eyes with filtering surgery a decrease of visual acuity from 0.7 +/- 0.3 to 0.6 +/- 0.3.
  
  
  CONCLUSIONS
  Combined surgery is perioperatively associated with a higher frequency of complications, but showed 12 months postoperatively equal values of regulated intraocular pressure.
