Acute Central Retinal Artery Occlusion Associated with Intraocular Silicone Oil Tamponade

Abstract

Many systemic and ocular factors may cause acute central retinal artery occlusion (CRAO). Herein, we aimed to describe a case of CRAO due to intraocular silicone oil (SO) tamponade. To the best of our knowledge, a case like our has not been reported previously. A 58-yearold male patient had undergone combined pars plana vitrectomy-lensectomy and intraocular SO for lens luxation and vitreus hemorrhage associated with a blunt ocular trauma in his right eye. Two weeks after the surgery, he presented with acute vision loss in the same eye. He was diagnosed with acute CRAO and it should be related with mechanical press or raised intraocular pressure (IOP) associated with SO. He was treated by partial removal of SO immediately. In spite of the regression of retina edema, his visual acuity did not improve due to optic atrophy. SO may cause CRAO due to raised IOP and/or its mechanical pressure and this complication must be kept in mind. (Turk J Oph thal mol 2012; 42: 238-40)
