title: Transpupillary argon laser photocoagulation and Nd:YAG laser cystotomy for peripheral iris pigment epithelium cyst.
abstract: OBJECTIVE
  To report the use of a combination of transpupillary argon laser photocoagulation and Nd:YAG laser cystotomy in the treatment of peripheral iris pigment epithelium (IPE) cyst.
  
  
  METHODS
  Case report.
  
  
  METHODS
  A 23-year-old man presented with a one-month history of blurred vision and pain in the right eye. Slit-lamp biomicroscopy and gonioscopy revealed, in the iridociliary sulcus, a large clear IPE cyst, which was demonstrated by ultrasound biomicroscopy (UBM). A combination of transpupillary photocoagulation to devitalize the epithelial lining and neodymium-doped yttrium aluminum garnet (Nd:YAG) laser cystotomy to drain the cyst was engaged.
  
  
  RESULTS
  Laser treatment resulted in vanishing of the cyst and disappearance of the subject symptoms. Two months postoperatively, no evidence existed of the iris pigment cyst regrowth.
  
  
  CONCLUSIONS
  The minimal invasiveness of the combination of transpupillary laser photocoagulation and cystotomy yielded a favorable result. This procedure may be an alternative to conservative regimen if IPE cyst is clearly defined and readily seen.
