Basic Science and Pathophysiology

No assessment of eye problems can be undertaken without a knowledge of the basic anatomy of the eye.

The majority of eye problems presenting to the ED relate to the anterior eye.

Common sites of injury and infection are:

  • Cornea
  • Conjunctiva
  • Eyelids

Visual disturbance can arise as a result of a problem with any structure along the visual axis or neural visual pathway.
