Chapter 14 Sensory Function
1. During accommodation, pupillary dilation partially compensates for the
reduced size of the retinal image by:
A) thickening the lens.
B) contracting the ciliary muscle.
C) increasing light entering the pupil.
D) narrowing the palpebral opening.
2. With aging, progressive inelasticity and thickening of the lens causes which
accommodation disorder?
A) Cataracts
B) Hyperopia
C) Presbyopia
D) Astigmatism
3. In order to maintain fixation on stable objects during head rotation,
compensatory movements occur.
, A) vertigo
B) nystagmus
C) conjugate gaze
D) eyelid vacillation
4. The red eyes of bacterial conjunctivitis are accompanied by ,
which differentiates it from the red eyes of acute glaucoma.
A) mydriasis and headaches
B) blurred or iridescent vision
C) tearing, itching and burning
D) cloudy, painful corneas
5. An acute episode of angle-closure glaucoma is preceded by:
A) central visual field loss.
B) prolonged pupil dilation.
C) corneal surface trauma.
D) vitreous humor fluid loss.
6. Diabetic and hypertensive retinopathy are both characterized by the
appearance of:
A) macular edema.
B) cloudy corneas.
C) microinfarctions.
D) intraretinal hemorrhages.
7. Although both vertigo and dizziness can result from peripheral or central
vestibular disorders, vertigo is distinctly different because it causes:
A) light-headedness.
B) an illusion of motion.
