d. Redness of sclera/conjunctiva.
(1) The sclera is the outermost layer of the eyeball and is made up of tough,
firm, connective tissue (see figure 5-1).
(2) The conjunctiva is the delicate membrane that lines the eyelids and
covers the exposed surface of the sclera (see figure 5-1).
e. Possible erosion of the corneal surface.

TREAT CHEMICAL BURNS TO THE EYE
a. Gently hold patient's eye open with your fingertip. Pain may make it difficult
for the patient to keep his eye open (see figure 5-2).
b. Use sterile water in flushing the patient's eye. If sterile water is not
available, use potable water, or IV solution. Any liquid that is safe to drink may be used
in an emergency (see figure 5-3).
