Silicone oil obscuring vision by migrating behind an intraocular lens in an intact capsular bag after previous retinal detachment surgery

摘要

Silicone oil is used on a regular basis during vitrectomy for the surgical management of complex or recurrent retinal detachment. Incomplete removal of particles can cause postoperative complications. A 68-year-old pseudophakic patient with previous retinal detachment surgery presented with reduced vision. On examination, silicone oil could be visualized lodged between the hydrophobic intraocular lens (IOL) and intact posterior capsule. YAG laser capsulotomy was performed to clear the visual axis and disperse the oil droplets into the vitreous cavity. Corrected distance visual acuity improved to 6/6 and symptoms resolved. Silicone oil can accumulate in the capsular bag after vitrectomy even in patients with an intact posterior capsule. It is important to ascertain the type of IOL material used during cataract surgery and to properly identify the positioning of the oil droplets to safely treat the patient and avoid unnecessary complications.
