Answer to Question 1

ANS: C
The HOTV test consists of a wall chart of these letters. The child is asked to point to a corresponding card when the examiner selects one of the letters on the chart. The cover test determines ocular alignment. The Ishihara test is used for the detection of color blindness. The Snellen letter chart is usually used for older children.

Answer to Question 2

ANS: B
Binocularity is usually achieved by ages 3 to 4 months. 1 month is too young. If binocularity is not achieved by ages 6 to 12 months, the child must be observed for strabismus.
