Objective evaluation of fusional vergence after a vision therapy protocol in typical binocular vision.

ABSTRACT:

Introduction

Vision therapy is an effective treatment option for binocular vision and accommodative anomalies. However, its effect on typical binocular vision is less documented. The aim of this study was to evaluate objectively the change in near fusional vergence amplitudes in adults with typical binocular vision after performing a vision therapy protocol.

Methods

Thirty-four adults were randomly classified into an experimental group (EG), who underwent a vision therapy protocol for 12 weeks, and a control group (CG), who received a placebo treatment for 12 weeks (Phase 1). In Phase 2, the CG performed the same therapy protocol as the EG. Fusional vergence amplitudes were measured objectively in a haploscopic set-up using smooth and step fusional vergence tests.
