title: A new approach to the Hirschberg test.
abstract: Forty patients with horizontal strabismus were examined in order to establish a correlation between measurements obtained by the alternate cover under the amblyoscope and measurements made by passively placing the corneal reflex in symmetry of that of the fixating eye. In order to reduce errors, the pupils were constricted to two mms and a very intense and bright one mm corneal reflex produced. Both measurements were very similar and a correlation of r=0,94 was found. Accuracy was significant at the p=0,005 level.
