A novel dynamic random-dot stereopsis assessment to measure stereopsis in intermittent exotropia.

ABSTRACT:

Background

To investigate dynamic stereopsis in intermittent exotropia [X(T)] patients using a novel dynamic random-dot stereopsis assessment method.

Methods

A novel dynamic random-dot stereopsis test was performed using novel self-programmed software, which consisted of red and green dots and four blocks on the screen. The test included motion + disparity (MD), motion (M), and disparity (D), where the D cues ranged from 200 to 1,200 arc-seconds. The characteristics of preoperative dynamic stereopsis in 83 X(T) patients and associations with clinical features were analysed, and the prognosis was followed up on the 1^st day and at the 2^nd, 6^th and 12^th months postoperatively.

Results

Preoperatively, the mean reciprocal values
