Abstract

I desire to report an interesting case having a total apparent strabismus—convergent—of 62°; with a view to demonstrating a method for this individual case by Professor Landolt, of Paris. From my clinical notes, taken at the time (1886), I present the following: A young man, 19 years of age, applied for treatment, "for loss of vision in the right eye." Ophthalmoscopic examination revealed:

Right and left eyes, hyperopia total, 3.5 D.

Right eye, convergent strabismus apparent, 52°.

Angle K (angle between the lens of fixation and the radius of the cornea, which passes through the pupil) +10°.

Therefore we have a case with a total convergent strabismus of 52°+10°=62°, an exceptionally high degree. The field of fixation, measured with Landolt's perimeter, was:

It will readily be observed that the field of fixation is strongly limited to the outer side of both eyes. Binocular vision abolished, it was found impossible to
