Binocular Approaches in Amblyopia Treatment Based on Dichoptic Stimulation

The discovery that binocular dysfunction may play a critical role in the development of amblyopia has led to the development of a novel approach based on contrast-rebalanced binocular stimulation of both eyes. This approach, known as dichoptic stimulation, enables the treatment of amblyopia by facilitating the cooperation of both eyes. Dichoptic treatment approaches are founded on the theoretical premise that binocular imbalance plays a significant role in both monocular and binocular impairments in amblyopia, and that preserving binocular function capacity is essential. Therefore, these approaches are designed to promote the collaborative functioning of the eyes, enhance stereopsis, and improve binocular fusion. This review systematically examines and synthesizes the existing literature on dichoptic stimulation techniques aimed at improving binocular function in the treatment of amblyopia. Based on various studies in the literature, the fundamental principles of these treatment methods are outlined, and the results obtained in comparison to traditional monocular treatments are highlighted. The clinical efficacy of dichoptic treatment methods is evaluated in terms of their contribution to enhancing binocular function in amblyopia. Additionally, information is provided regarding the outcomes, treatment durations, efficacy levels, and potential side effects of these treatment approaches in different patient groups. This review offers a comprehensive assessment of the integration of dichoptic treatment approaches into clinical practice, highlighting both their advantages and disadvantages, and aims to provide a guiding perspective on their future use.
