Blunt Injuries to the Eye
A blunt impact may damage the structures at the front of the eye (the eyelid, conjunctiva, sclera, cornea, iris, and lens) and those at the back of the eye (retina and optic nerve). Such an impact may also break (fracture) the bones that surround the eye. Blunt trauma occasionally also results in cuts (lacerations) to the tissues of the eye.
Injured eyes may be very swollen and difficult to open. Still, doctors need to open the eyes to examine them and make sure there is no injury that will affect vision. The eyes almost always can be opened gently, although instruments may be needed to do so.
BLUNT TRAUMA can cause:
1 . black eye
2 . subconjunctival hemorrage
3 . hyphema
4 . retinal detachments
5 . fractures
