Answer to Question 1

Correct Answer: 1, 4
The use of morphine and narcotic drugs may cause small pupils with poor response to light. The use of anticholinergic drugs such as atropine may cause dilated, poorly responsive pupils. Pupils that are unequal in size may indicate previous eye surgery or a serious neurologic problem, such as increased intracranial pressure. One dilated and unresponsive pupil may indicate paralysis of the oculomotor nerve.

Answer to Question 2

Correct Answer: 1, 2, 3
Retinitis pigmentosa results in progressive night blindness, with loss of visual acuity and peripheral vision. A patient who has one dilated and unresponsive pupil may have paralysis of the oculomotor nerve. A change in blue-green perception is an age-related change caused by the atrophy of photoreceptor cells in the eyes.
