Small oil droplets in the eye after surgical treatment of retinal detachment are usually caused by the fact that when the silicone oil is removed, some of the silicone oil droplets are attached to the wall of the eyeball and cannot be removed completely, and there is no good way to eliminate them. If there is no obvious discomfort, it can be observed, and complications such as elevated intraocular pressure can be treated with surgery. Patients with retinal detachment usually need to be treated by surgery, such as vitrectomy, during which silicone oil is injected into the eye to press against the retina to promote its restoration, and the silicone oil can be removed when the retina is restored to its original position. However, some small droplets of silicone oil may adhere to the wall of the eye, making it impossible to remove all of the silicone oil. These droplets may break away from the wall of the eye and cause a round black shadow to float in the patient’s field of vision, and there is no good way to remove them. If the patient has no obvious discomfort, he can be observed and followed up. If complications such as elevated intraocular pressure occur, the patient can be treated with trabeculectomy. It is recommended that postoperative retinal detachment patients follow the doctor’s instructions, have regular checkups, and consult a doctor when discomfort occurs.
