Penetrating TraumaAnother type of ocular traumatic injury is penetrating foreign body. This type of injury develops, usually, when a metallic fragment ricochets into the eye as a result of hammering on a metallic object for instance. Steel fragments are the most common type. They can be removed, oftentimes, by applying a strong magnetic force to the side of the eye (in an operative procedure). If there is no response, a needle-like forceps must be introduced into the eye to grasp the foreign body (as was done successfully, for the wire-like object shown below).
