Silicone oil removal-related vision loss.

Abstract

Silicone oil removal-related vision loss (SORVL) is a sight-threatening condition affecting a small fraction of patients after the removal of silicone oil, possibly underestimated. To date, a few cases have been thoroughly investigated; however, no clear and unique explanation has been found for this phenomenon. Most of the literature has been focusing on SORVL and in situ SORVL, gathering the 2 conditions under the same pathogenic mechanism. In this review, we provide a detailed update on SORVL describing its epidemiology and the reported signs and symptoms. Furthermore, we explore possible underlying mechanisms that may contribute to the development of SORVL giving insights into the pathophysiology of this rare and severe condition.
