A 77-year-old client being treated for glaucoma asks the nurse what causes glaucoma. The nurse's response is:
a. the exact etiology of glaucoma is variable and often unknown.
b. spasms of the orbicular muscle.
c. changes to the suspensory ligaments, cili-ary muscles, and parasympathetic nerves.
d. bits of broken coalesced vitreous from the peripheral or central part of the retina.
ANS: A
The etiology of glaucoma is variable and often unknown. However, when the natural fluids of the eye are blocked by ciliary muscle rigidity and the buildup of pressure, damage to the optic nerve occurs. Spasms of the orbicular muscle can cause the lower lid to turn inward. If it stays this way, it is called entropion. The changes described contribute to decreased accommodation. Bits of coalesced vitreous that have broken off from the peripheral or central part of the retina is the definition of floaters.
