Question 5

The Hirschberg test shows the corneal light reflex displaced 2 mm nasally in the left eye. This suggests approximately:

Accepted Answer

15 prism diopters of esotropia

Answer

Each 1 mm of corneal reflex displacement approximates 15 prism diopters, so 2 mm nasally equals roughly 30 PD esotropia — but the standard teaching is ~15 PD per mm.
