The orthophorization of heterophoria
1Department of Ophthalmic Optics, University of Manchester Institute of Science and Technology, U.K.
Abstract:
The distribution of heterophoria within the general population is significantly non-normal and a high incidence of approximate orthophoria is observed. This observation has been named the orthophorization of heterophoria. It has been suggested that prism adaptation is the mechanism underlying orthophorization. A prolonged occlusion experiment has been used to investigate this possibility and further supports this theory.
