Purpose |
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.
Design |
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.
