Intraocular Foreign Bodies
Causes of Intraocular Foreign Bodies
Explosions and any tool with a metal-on-metal mechanism can cause intraocular foreign bodies by causing small particles to fly in a person’s face. For example, using high-speed machines (such as drills and saws) or hammering a nail or other metal object with a hammer can produce white-hot particles of metal that resemble sparks. Any of these white-hot particles can enter the unprotected eye and become embedded deep within it. Foreign bodies that penetrate the inside of the eye can damage the structures within the eyeball and lead to an infection inside of the eye ( Endophthalmitis ).
