In this report a 31-year-old man who underwent successful endoscopy-assisted removal of foreign body in anterior chamber angle after a failed conventional surgery through limbal incisions was performed. The patient presented to our hospital complaining of redness and decreased vision in his left eye secondary to ocular trauma. One day prior the patient was hammering metal when the injury occurred. Upon examination, gonioscopy, orbital computed tomography (CT) and ultrasound biomicroscopy (UBM) revealed a foreign body in the inferior anterior chamber angle of his left eye. To remove the foreign body by a routine microscopic surgery through limbal incisions was failed. Five days after the first surgery, gonioscopy revealed peripheral anterior synechia in the inferior angle and UBM examination showed that the foreign body was embedded in the angle structures. With the assistance of endoscopy, the foreign body was removed through the existing limbal incision with forceps.
