Being able to see oil splashes after retinal surgery is usually caused by drops of silicone oil inside the vitreous humor. Commonly used surgical procedures for retinal surgery include vitrectomy, while patients with diseases such as retinal detachment need to have silicone oil injected inside the eye to press against the retina to promote retinal reset during surgery. Generally, the silicone oil can be removed three to six months after surgery, but some drops of silicone oil may still remain in the eye, causing the patient to look at things as if they were floating in oil. When removing the silicone oil, we usually try to flush the eyeball with an irrigation solution to facilitate the discharge of the remaining drops, but inevitably a small amount of silicone oil drops will remain, which is normal, and the patient does not need to be nervous.
