New apparatus for measuring forces in strabismus.
An apparatus for measuring muscle forces in strabismus has been developed. The globe is fixed with a modified suction cup, force applied is measured by strain gauges, and the excursion of the globe is measured by a light pointer and tangent screen. The values of force generation tests for normal horizontal rectus muscles performing 30 degrees saccades lie mainly within the range of 60 to 80 G.
