We present a case with conjunctival inclusion cyst at inferior fornix treated by marsupialization.

A 23-year-old woman visited our clinic complaining of left lower eyelid swelling. Ophthalmologic examination and CT scan showed a cystic mass from inferior conjunctival fornix to anterior orbit with shallow fornix and focal symblepharon. The cyst was effectively removed with marsupializaion. Postoperatively, there was no recurrence of cyst and the fornix was deepened.

Marsupialization can be a considerable treatment option in conjunctival inclusion cyst, especially when accompanied by shallow fornix and symblepharon.
