Making stereopsis related to the ability of ocular deviation: a new paradigm for assessment of intermittent exotropia.

ABSTRACT:

Aim

To investigate the underlying factors by establishing a new paradigm for assessing control ability under stereopsis testing conditions.

Methods

This was a prospective observational study. We evaluated the control ability of intermittent exotropia (IXT) patients in three conditions: natural 2D optotype viewing, 2D optotype viewing with polarized glasses, and 3D optotype viewing with polarized glasses. Recording with a smartphone, we captured videos to analyze the accurate time of spontaneous exodeviation and subsequent realignment before and after breaking fusion. Additionally, the correlation of stereopsis were also analyzed.

Results

A total of 48 patients (age range: 4-33y; 54.17% male) participated in the study. When viewing 3D optotypes with polarized glasses,
