Purpose

To describe a minimally invasive surgical approach of IOFB removal based on the exact identification of its location through multimodal preoperative imaging.

Setting/Venue

Ophthalmology Department, G. Gennimatas Athens General Hospital NHS Trust, Vitreoretinal Service

Methods

Case presentation, step-by-step high-definition video analysis

Results

40-year-old male, hit in his left eye by a high velocity metallic foreign body while working in an elevator shaft and referred for further management after primary wound closure elsewhere. BCVA upon presentation 6/9, left. Dilated fundus examination, axial CT and cranial X-ray scans confirmed the presence of an IOFB. Further multimodal imaging applying midperipheral spectral domain OCT and B scan ultrasound identified its exact intraretinal location without definite encapsulation. Intraoperatively, a step-by-step approach was applied in an attempt to minimize mechanical neuroretinal manipulation upon removal of the IOFB achieving a satisfactory functional and anatomic outcome.

Conlusions

Treatment and rehabilitation of complex ocular trauma requires a detailed surgical plan based on comprehensive preoperative imaging in order to exactly localize the IOFB and remove it while minimizing the overall surgical morbidity
