Subconjunctival cysts following silicone oil injection: a clinicopathological study of five cases.
OBJECTIVE
To study the occurrence, risk factors and management of subconjunctival cysts formed following the use of intraocular silicone oil as a tamponade.


METHODS
We analyzed 5 cases of single and multioculated subconjunctival oil cysts between 1986 and 1996.


RESULTS
Cysts were observed 15 days to 4 months following silicone oil injection. Clinically they showed minimal inflammatory signs but histopathology of removed cysts showed emulsified silicone oil globules with chronic inflammatory cellular infiltration.


CONCLUSIONS
Though silicone oil is considered to be nontoxic, it can cause chronic inflammation when spilled into the subconjunctival space.
