Concept
Eye injury
Summary
Physical or chemical injuries of the eye can be a serious threat to vision if not treated appropriately and in a timely fashion. The most obvious presentation of ocular (eye) injuries is redness and pain of the affected eyes. This is not, however, universally true, as tiny metallic projectiles may cause neither symptom. Tiny metallic projectiles should be suspected when a patient reports metal on metal contact, such as with hammering a metal surface. Corneal foreign body is one of the most common preventable occupational hazard. Intraocular foreign bodies do not cause pain because of the lack of nerve endings in the vitreous humour and retina that can transmit pain sensations. As such, general or emergency department doctors should refer cases involving the posterior segment of the eye or intraocular foreign bodies to an ophthalmologist. Ideally, ointment would not be used when referring to an ophthalmologist, since it diminishes the ability to carry out a thorough eye examination.
Flicking sand, flying pieces of wood, metal, glass and stone are notorious for causing much of the eye trauma. Sporting balls such as cricket ball, lawn tennis ball, squash ball, shuttlecock, and other high speed flying objects can strike the eye. The eye is also susceptible to blunt trauma in a fistfight. Children’s games such as bow-and-arrows, bb guns and firecrackers can lead to eye trauma. Road traffic accidents (RTAs) with head and facial trauma may also have an eye injury - these are usually severe in nature with multiple lacerations, shards of glasses embedded in tissues, orbital fractures, severe hematoma and penetrating open-globe injuries with prolapse of eye contents. Other causes of intraocular trauma may arise from workplace tools or even common household implements, including bottle-caps suddenly propelling at great force.
About 5.3 million cases of foreign bodies in the eyes occurred in 2013.
Multiple complications are known to occur following eye injury: corneal scarring, hyphema, iridodialysis, post-traumatic glaucoma, uveitis cataract, vitreous hemorrhage and retinal detachment.
