title: Retrospective Comparison of Intermediate-term Efficacy of 350 mm2Glaucoma Drainage Implants and Medium-sized 230-250 mm2Implants.
abstract: OBJECTIVE
  To compare the intermediate-term efficacy of a large surface area Baerveldt 350 mm2glaucoma drainage device (GDD) with medium surface area implants (Baerveldt 250 mm2and Molteno 3, 230, or 245 mm2).
  
  
  METHODS
  This is a retrospective, nonrandomized comparative trial.
  
  
  METHODS
  A total of 94 eyes of 94 patients of mixed glaucoma diagnoses without any prior glaucoma surgical procedures and who had undergone a glaucoma drainage implant surgery with either a large Baerveldt 350 mm2GDD or a medium-sized GDD (Baerveldt 250 mm2or Molteno 230 or 245 mm2) were reviewed for intraocular pressure (IOP), number of glaucoma medications, and visual acuity (VA) preoperatively, and at 1, 2, and 3 years postprocedure.
  
  
  RESULTS
  No significant differences were found in mean IOP, number of glaucoma medications used, and VA at 1, 2, and 3 years postoperatively. The rate of additional glaucoma procedures was similar between the two groups.
  
  
  CONCLUSIONS
  There is no clear evidence that a larger implant surface area beyond 230 to 250 mm2is advantageous in providing intermediate-term IOP control.
  
  
  CONCLUSIONS
  It may be technically easier to surgically place a GDD that does not need to have its wings placed underneath the recti muscles, and the IOP results are similar.
