ABSTRACT:
A method and apparatus for determining the strabismus angle between the optical axes of a fixing and of a strabismic eye, characterized in that from two light sources, the spacing of which from one another is adjusted to the pupillary distance of the fixing and of the strabismus eye respectively, one eye each is illuminated and a light reflection on the cornea of each eye is produced. By means of two optical receiving devices, the optical axes of which likewise are adjusted from one another to a distance corresponding to the pupillary distance of the eyes, the pupils of both eyes and both of the light reflections on the corneas of both eyes are imaged on one common image plane.
