title: [Monitoring intraocular pressure and therapy after trabeculectomy in both eyes during a 2-year period].
abstract: OBJECTIVE
  To evaluate the level of intraocular pressure (IOP) and glaucoma therapy during two years after trabeculectomy (TE) with two releasable sutures (RS) on the first and the second operated eye.
  
  
  METHODS
  In a retrospective study, preoperative and postoperative IOP and glaucoma therapy in 40 patients with open angle glaucoma, were evaluated. Patients underwent standardized TE with two RS on both eyes performed by the same surgeon. The first (worse) eye was operated on an average of three years after the diagnosis of glaucoma, and after 8.2 +/- 6.9 months the second (better) eye was operated on.
  
  
  RESULTS
  TE with RS significantly decreased the level of IOP (p < 0.0001) and therapy (p < 0.0001) during a two year follow up period. There was no significant difference in IOP (p = 0.226) and glaucoma therapy (p = 0.086) between the first and the second operated eye. IOP was stabilised within 2-3 months after surgery for most patients, however glaucoma therapy was added for some to keep the target pressure. After one year IOP and therapy were stable for all patients.
  
  
  CONCLUSIONS
  There is no difference between the first-worse and the second-better operated eye regarding IOP and glaucoma therapy during a two year period.
