Fusion exercises for treatment of intermittent exotropia and phoria.

Abstract

INTRODUCTION:

Fusion exercises have been used in the management of intermittent exotropia (X(T)) for over one hundred years. The opinions regarding their efficacy are controversial.

PATIENTS AND METHOD:

Dynamics of binocular status were investigated retrospectively in ninety-six patients with X(T). Forty-eight subjects had specific orthoptic treatment (treatment group). Forty-eight had no orthoptic treatment (control group). Both groups were matched for age, sex, and race. The orthoptic treatment consisted of a cat stereogram, home-based fusion exercises, which patients were asked to perform twice daily.

RESULTS:

The treatment group showed significant enhancement of binocular function, particularly control of strabismus and stereoacuity for distance. The control group showed further deterioration of binocular functions.

CONCLUSION:

Our results suggest patients with X(T) objectively improve their binocular function after fusion exercises.
