In the left eye examination; best corrected visual acuity (BCVA) was counting fingers at 1 meter, at biomicroscopic examination tobacco dusts in the anterior vitreous was noticed and at fundus examination retinal detachment at inferior half with off macula, a round retinal tear with operculum in the inferior nasal quadrant, and grade B proliferative vitreoretinopathy were detected. Twenty-three gauge (G) pars plana vitrectomy(PPV), phacoemulsification+intraocular lens implantation, endolaser photocoagulation around the tear were performed. Silicon oil(SO)1300 cst was used as retinal tamponade. The patient was given 1% prednisolone acetate 6x1, 0.3% ofloxacin 4x1, and 1% tropicamide 3x1 for one month after surgery. BCVA was 0.4(snellen), central macular thickness(CMT) was 296 μm, intraocular pressure was 30 mmHg at 4 months postoperatively. SO extraction, fluid-air-20% sulfur hexaflorur exchange were performed using a 23 G trocar (with valve) system. Two months after SO extraction, BCVA was decreased (from 0.4 to 0.2), retina was reattached with an appearance similar to macular edema. Optical coherence tomography showed increas macular thickness and a shadow behind the hyperreflective area. CMT was 406 μm. The findings were considered as an iatrogenic intraocular foreign body (IOFB). IOFB was removed via pars plana with 23 G forceps and examined under the microscope. It was a silicon piece of the flute needle tip. BCVA was increased and CMT was improved after removing IOFB.
