Although abrasion injuries are painful, they usually heal quickly after treatment. Secondary complications of contusion may be traumatic cataract or secondary glaucoma. Thermal burns damage eye tissue much as they do other skin tissues, but corneal burns may result in opaque scar tissue. Intraocular foreign bodies are the most serious type of penetrating wounds.
Treatment varies according to the type and extent of the wound.
Most superficial wounds are painful but heal well with treatment. Subconjunctival hemorrhages appear worse than they are, and usually self-absorb in time. Internal ocular injury is less visible and always requires examination by a medical eye specialist. Tetanus inoculation is indicated whenever the eye is penetrated by injury.
