Primary stromal iris cysts treated successfully with ab externo laser Nd:YAG photocoagulation

Two boys presented with primary solitary stromal iris cyst in the inferior quadrant. Both patients were treated with Nd:YAG laser puncturing the cyst wall. The cyst wall collapsed and fluid leaked out in the anterior chamber. No complication was noted. The cyst recurred in the first child at 2 months of follow-up and was re-treated with laser. There was no further recurrence after 12 months of follow-up in case 1 or after 10 months of follow-up in case 2. To the authors' knowledge, this is the first documented report of Nd:YAG treatment of primary stromal cyst.
