Iris cysts: Varied presentations and review of literature.

An iris cyst is a nonkeratinized squamous epithelial-lined space involving a layer of iris. The presentation of iris cyst can be variable-innocuous or presenting with secondary complications. The identification of whether the cyst is primary or secondary is important. The prognosis of primary iris cysts is good, as the majority does not require treatment and that of secondary iris cysts is much more capricious depending on their presentation. Their optimal management often poses a challenge for ophthalmologists. Here, we will present two cases of iris cysts with diverse presentation along with a review of the literature of this rare clinical entity.
