A client is having intraocular pressure measured for both eyes. Which response by the client best indicates that the client understands why this is necessary every year?
a. "Elevated eye pressure can cause high blood pressure."
b. "If eye pressure is too high, your eyes will dry out."
c. "Elevated eye pressure can press on blood vessels in the eye."
d. "Increased eye pressure causes the tear ducts to become blocked."
C
Intraocular pressure is the pressure generated by the fluids inside the globe of the eye. As intra-ocular pressure increases to above normal, it compresses the blood vessels and the optic nerves. As the blood vessels are compressed, oxygenation to the internal eye structures, including the nerves and photoreceptors, is diminished. The nerves and photoreceptors require a constant supply of oxygen and will die if blood flow is inadequate, leading to blindness. The other state-ments are inaccurate.
