[A case of ocular siderosis caused by iron ore]

A patient complained of vision loss of his left eye which was crushed by iron ore for 11 months. The cornea of the injured eye was thin and swollen, and a large amount of rust-like material was observed to be deposited. An intraocular foreign body was found by orbital CT. During vitrectomy, a piece of metal sheet was found near the ora serrate, and the intraocular structure was severely damaged, and characterized by vitreous brown turbidity, a white optic disc, occlusion of blood vessels in the fundus, and peripheral retinal atrophy with degeneration.
