Answer to Question 1

ANS: C
Visual fixation and following a target should be present by ages 3 to 4 months. One to 2 months is too young for this developmental milestone. If the infant is not able to fix and follow by 6 months, further ophthalmologic evaluation is needed.

Answer to Question 2

ANS: D
The Snellen letter chart, which consists of lines of letters of decreasing size, is the most frequently used test for visual acuity for school-age children. Single cards (Denverletter E; Allenpictures) are used for children ages 2 years and older who are unable to use the Snellen letter chart. The Ishihara vision test is used for color vision.
