PDS from Iris Cysts (2)

This 47 year-old man presented with bilateral narrow angles. On examination he was found to have large iris cysts of the pigment epithelium. His intraocular pressures were normal in both eyes but there were portions of his iridocorneal angle that were closed and therefore an iridotomy was performed in the left eye. This video shows the patient before and after the iridotomy. This patient also had pigment dispersion caused by abrasion of the pigment epithelium against the lens zonules.
