Herein, we report a patient who complained of progressive, painless blurring of vision in the left eye for six months. On examination, a large smooth non-transilluminant iris mass was seen extending from 11 o'clock to 5 o'clock region and touching the corneal endothelium. Surgical excision was performed and the patient's vision improved from HM to 6/48. http://pubs.sciepub.com/ajmcr/4/6/9/ajmcr-4-6-9.pdf non-traumatic iris cyst large acquired iris cyst trypan blue
