Abstract

Incidence of ocular injuries is high although it is well protected by the bony orbit and surrounding structures. It is an emergency requiring immediate management. Injury may occur by foreign body or chemicals. It may be blunt injury or penetrating or perforating injury. Chemical burns may be due to alkalies or acids and need emergency management starting with thorough washing of the eye. Injuries with blunt objects may range from simple abrasion to rupture of the globe and can damage the cornea, sclera, iris and ciliary body, lens, vitreous, choroid, retina or the optic nerve. Penetrating injury is a single full thickness wound of the eyeball caused by a sharp object. In perforating injury, there is a double full thickness wound with entry and exit wounds due to a sharp object. Foreign body may be retained in the eye with penetrating injury and cause damage due to mechanical effect, infection or specific chemical action of metals. Siderosis bulbi is due to electrolytic dissociation of the iron metal by the current of rest in the eye leading to atrophy of cells. Chalicosis is due to foreign body with pure copper content giving rise to a violent suppurative reaction with shrinkage of globe. Sympathetic ophthalmitis is a condition in which the normal eye gets seriously inflamed after injury to the other eye. Unless steroids are started early, the prognosis may not be good.
