Neodymium YAG Laser Cystotomy for Giant Secondary Iris Cyst

Abstract

We aimed to report a case with giant secondary iris cyst that was successfully treated with Neodymium YAG laser cystotomy (Nd: YAGLC). The case was 79 years old man having the visual loss in his left eye for several months. The visual acuity of his left eye was at the level of finger counting from one meter. The slit-lamp biomicroscopy revealed pseudoaphakia and a giant iris cyst in the chamber of the left eye unless intraocular pressure elevation. After Nd: YAGLC was applied to the cyst, it dramatically shrank and disappeared. At the 6th month following the treatment, there was no recurrence of the cyst. Nd: YAGLC is a safely treatment modality to be able use to effectively treat the giant secondary iris cyst without intraocular penetration.
