Excerpt

Although silicone oil is widely used as an effective intraocular tamponade agent, it can cause various complications for cases with long-term tamponade, such as patients with cataracts, glaucoma, keratopathy, a preretinal membrane, or subretinal silicone oil movement. Therefore, immediate removal of silicone oil after retinal adhesion is recommended.1–3 Migration of silicone oil into the anterior chamber can also occur and induce damage to corneal endothelial cells and elevate intraocular pressure (IOP).4 The methods for completely removing silicone oil in the anterior chamber required removing all the silicone oil from the anterior chamber and the vitreous cavity and then reinfusing oil into the vitreous chamber; however, this method is time-consuming and complex, and retinal redetachment can occur during silicone oil removal.
