This 42-year-old man was struck below the left eye eleven years ago.  Immediately afterward he noted that the left eye was deviated upward and he saw double.  He has no other complaints now.  Visual acuity is 20/20 in each eye unaided.  Except for the left hypertropia and the limited depression in the left eye, his eyes are normal.  Because of the large deviation, it has not been possible to test him adequately for single binocular vision with prism.

1.	Examination at this time would include:
	a. careful fundus examination with emphasis on the inferior periphery b. biomicroscope examination of the anterior segment c. saccadic velocity testing far up and far down gaze d. all of the above
2.	The most important next test would be:
	a.  prism and cover measurements in the primary position,      upward and downward with either eye fixing b. determination of past pointing c. determination of Botox sensitivity d. corneal sensitivity
