A Rare Complication Causing Another Rare Complication: Corneal Dellen with Infiltration Secondary to Subconjunctival Silicon Oil

The usage of silicon oil (SO) in vitreoretinal surgery is associated with potential complications. One such complication is the extravasation of SO into the subconjunctival space through open sclerotomies. Subconjunctival SO (SCSO) can cause irregularities in the ocular surface which predisposes to complications like corneal dellen. This corneal dellen can get infected in rare situations. SCSO needs to be removed to stabilize the ocular surface. We present a case of corneal dellen with infiltration which developed as a consequence of SCSO and its management.
