Background: A multitude of ophthalmic treatment and management strategies have been successful for the treatment of exotropia, some of which include home-based exercise programs and vision training programs. Vision training has been found to be successful in improving stereovision, giving patients the ability to see in 3D, and for convergence insufficiency. Case Report: This report describes a 14-year-old female athlete presenting with post-operative left eye exotropia with hyperphoria who was not able to appreciate stereopsis. A personalized action plan was designed to minimize suppression and to improve left-right ocular motor symmetry, which included home exercises and structured vision training. In the 29-week program, stereopsis improved from 0.00 mm to 16.00 mm. With regular vision training, the patient demonstrated improved stereopsis, decreased suppression, better precision of fixation, improved eye discipline of the left eye, and better coordination of both eyes. Ultimately, she was able to appreciate 3D. Conclusions: Vision training, as part of the post-corrective surgery rehabilitation program, can restore the ability to see in 3D. Vision training for consecutive exotropia and rehabilitation of stereoscopic vision can be achieved without interrupting sports-specific activities and competitive play.
