title: [Changes of blood-aqueous barrier after phacoemulsification in patients with previous glaucoma filtering surgery].
abstract: OBJECTIVE
  To evaluate the effect of trabeculectomy and/or phacoemulsification surgery on blood-aqueous barrier function.
  
  
  METHODS
  Phacoemulsification with implantation of intraocular lens was performed on 46 cataract eyes of 40 glaucoma patients following previous trabeculectomy (group 1), and 64 cataract eyes of 60 patients (group 2). The aqueous flare and cells were examined preoperatively and on days 1, 7, 30, 90 postoperatively using a laser flare-cell meter (LFCM).
  
  
  RESULTS
  The mean aqueous flare values were (15.12 +/- 2.87), (40.24 +/- 3.75), (24.33 +/- 3.38), (21.18 +/- 1.77), (16.51 +/- 1.70) photon counts/ms in group 1 preoperatively and on days 1, 7, 30, 90 after surgery (P < 0.05) respectively; and were (6.94 +/- 2.34), (26.27 +/- 10.21), (13.96 +/- 6.44), (9.07 +/- 2.67), (7.16 +/- 1.89) photon counts/ms in group 2 (P < 0.05) respectively.
  
  
  CONCLUSIONS
  Trabeculectomy can breakdown blood-aqueous barrier permanently while phacoemulsification damage the blood-aqueous barrier transiently. Phacoemulsification combined with a previous trabeculectomy can enhance this damage.
