Lateral Heterophia Sequentially Measured by a Stepping Prism System

Puntos clave

This research aims to evaluate lateral heterophoria using a stepping prism to detect variations.
Utilized a computer-controlled stepping prism system for measurements.
Applied a modified version of Von Graefe's method.
Captured phoria variations sequentially, starting from the break of fusion.
Sequential measurements revealed characteristics of heterophoria not seen in single measurements.
Identified phoria variations that provide deeper insights into eye alignment.

Resumen

ABSTRACT Lateral heterophoria values have been measured sequentially by means of a computer controlled stepping prism. Von Graefe's method, with minor modifications, was used. A modification of this method is shown by which phoria variations can be followed, starting from the break of fusion. These subjective measurements of heterophoria show characteristics that would not be revealed by a single measurement.
