[Can the use of intraocular silicone oil increase the risk of sympathetic ophthalmia?].
METHODS
We report two cases of SO (sympathetic ophthalmia) among 1,456 vitrectomies and 255 silicone oil injections performed since 1990. In both patients intraocular silicone oil was used. Both cases were clinically documented and one pathologically demonstrated.


CONCLUSIONS
No cases were reported among vitrectomies without silicone oil. We found a longer delay between injury and the onset of the disease in comparison to the literature. Pathological findings confirmed a foreign body granulomatous reaction. Chronic inflammation caused by silicone oil might be involved in the development of SO. Larger series are necessary to establish a possible relationship between silicone oil and SO.
