Abstract
We report an unusual case of asymptomatic subconjunctival entrapment of a cilium. A 64-year-old man presented with a 3 month history of a painless black line in the conjunctiva of the left eye, and slit-lamp examination revealed a cilium under the conjunctiva. The patient remained asymptomatic without conjunctival edema or hyperemia during a 2 week follow-up. To the best of our knowledge, this is the first report of an asymptomatic cilium inside the subconjunctival space.
