title: Encapsulated filtering blebs after trabeculectomy with mitomycin-C.
abstract: OBJECTIVE
  To determine the frequency of encapsulated blebs after guarded filtration procedures with mitomycin-C.
  
  
  METHODS
  The authors reviewed the charts of all patients who had undergone a guarded filtration procedure with mitomycin-C. There were 235 patients (283 cases) who had more than 1 month of follow-up.
  
  
  RESULTS
  An encapsulated bleb developed in 7 eyes (2.47%) of 6 patients. Identification of bleb encapsulation occurred at a mean follow-up time of 29.7 +/- 14.6 days after surgery. The mean intraocular pressure at that point was 24.2 +/- 13.5 mm Hg in the affected eyes. Three eyes were treated medically, and needling was performed in 4 eyes.
  
  
  CONCLUSIONS
  There is a low frequency of encapsulated bleb formation after guarded filtration procedures with adjunctive mitomycin-C.
