Abstract
Purpose: To evaluate usefulness and safety of removal of silicone oil from the vitreous cavity via the anterior chamber.
 Methods: The procedures were performed between 2012 and 2020 in 31 patients who required endotamponade with the use of light silicone oils. In most of the patients, the procedure was combined with cataract removal, secondary lens implantation or transscleral fixation of an artificial lens. A passive bimanual technique was used to replace silicone oil with fluid.
 Results: The procedure to remove silicon oil via the anterior chamber proceeded without serious intra- and postoperative complications. There were no hypotony observed in first postoperative day.
 Conclusion: Patients eligible for the procedure are those who have preoperative indications for silicone oil removal and whose removal path via the anterior chamber is not associated with a special need to remove the lens from the eye.
Highlights
Removal of silicone oil from the vitreous cavity constitutes a permanent part of retinal surgery
The anatomical condition of the eye, intraocular pressure (IOP) values achieved on the first postoperative day and 30 days after surgery like observed complications were analysed
The procedure to remove Silicon oil (SO) via the anterior chamber proceeded without serious intra- and postoperative complications
Summary
Removal of silicone oil from the vitreous cavity constitutes a permanent part of retinal surgery. Silicone oil endotamponade is used in many diseases, the most frequently mentioned ones being retinal detachment, ocular complications of diabetes or eye trauma [1]. Due to their gravity, silicone oils can be divided into light and heavy silicone oils. The most common is pars plana, active aspiration using the 2 or 3 port technique Another option is passive oil removal in the same way. In the case of heavy silicone oil, due to its high specific gravity, greater than specific gravity of water, the technique of active aspiration from the eye constitutes the only possible way of its removal [4], [5]
