Purpose: We present our findings in a case with an intraocular foreign body in which the electroretinographic (ERG) findings were useful.Observations: A 37-year-old man was injured by an iron fragment that penetrated into his left eye through the cornea.His visual acuity was counting fingers, and a traumatic cataract prevented an examination of the fundus.B-mode ultrasonography showed a stick-like foreign body of approximately 14 mm in length in the eye.

Preoperative ERGs with a contact Sneakers for Men - Grey - Canvas Mesh Athletic Running Shoes lens electrode showed reduced responses with many blinking artifacts.Lensectomy and pars plana vitrectomy were performed and a fragment of a wire brush was seen embedded in the superior nasal retina which was removed.The decimal visual acuity improved to 1.2 two weeks later.

The postoperative ERG performed with a skin electrode showed nyx 22 brush reduced responses in the injured eye.Conclusions and importance: We recommend that the physiology of the retina be assessed by recording ERGs with a skin-type electrode as soon as possible after a traumatic injury to the eye.Keywords: Electroretinography, Skin electrode, Intraocular foreign body, Pars plana vitrectomy.
