The Effectiveness of Visual Training in Convergence Insufficiency Patients

Visual training is the main type of management for CI patients clinically; however, the existing training protocol required patients to make several visits to the clinic for visual training, which might increase the burden for patients and result in higher failures in training. Therefore, this study will use a simple training method by utilizing prisms for CI patients to train at home, then compare visual symptoms and binocular vision after the training.
