Station six
(allowed 5 minutes)
A 5 year-old boy is esotropic as shown below.
Orthoptic assessment reveals an esotropia of 60 D with a visual acuity of 6/6 in the right eye and 6/24 in the left. The AC/ A ratio is 7.

Cylcoplegic refraction gives the following results:

Right eye + 2.00 DS
Left eye + 8.00 DS

Interpupillary distance with distant fixation.

Interpupillary distance with cover test
and distant fixation.
a. What will happen to the esotropia when he wears the 
     glasses?

b. What is the interpupillary distance (in mm) for the 
     glasses?
