Vertical vergence adaptation for normal and hyperphoric patients

Academic Article


  • This paper discusses the use of vertical fixation disparity (VFD) measurements to determine a patient’s ability to adapt to vertical prism. Vertical vergence adaptation for orthophoric patients, hyperphoric patients, and patients with vertical deviations associated with superior oblique paresis is reported. The effect of orthoptic training on the ability to adapt to vertical prism is also reported. © 1992 American Academy of Optometry.
