A client does not understand why vision loss due to glaucoma is irreversible. What explanation by the nurse is best?
a. "Because eye pressure was too high, the tissue died."
b. "Glaucoma always leads to permanent blindness."
c. "The traumatic damage to your eye was too great."
d. "The infection occurs so quickly it can't be treated."
ANS: A
Glaucoma is caused when the intraocular pressure becomes too high and stays high long enough to cause tissue ischemia and death. At that point, vision loss is permanent. Glaucoma does not have to cause blindness. Trauma can cause glaucoma but is not the most common cause. Glaucoma is not an infection.
