What should the nurse suspect a patient is developing when he is observed holding his Bible 6 inches from his face and turns his head to read out of the corner of his eyes?
Glaucoma
Cataracts
Macular degeneration
Presbyopia
The Correct Answer is C
A. Glaucoma
In glaucoma, peripheral vision is lost first, so people look straight ahead and miss things to the side. Not consistent with looking out of the corner of the eyes.
B. Cataracts
Cataracts cause overall blurry vision, not central vision loss. People may complain of glare or faded colors.
C. Macular degeneration
Involves loss of central vision, leading the person to use peripheral vision (look from the corner of the eye) and hold objects very close.
D. Presbyopia
Affects the ability to focus on near objects, common with aging, but does not cause the person to use peripheral vision.
