Abstract

The review presents new ideas about developmental mechanisms of amblyopia, which are currently discussed in literature. Objective evidence has accumulated that amblyopia affects both monocular and binocular functions in visual processing. Given the increasing evidence of fundamental and clinical research, it is most likely that binocular dysfunction is primary, and monocular reduction is visual acuity is secondary to this disease. Amblyopia is rather binocular than monocular pathology, and binocular interaction seems to play a critical role in the pathogenesis of strabismic, anisometropic and combined forms of amblyopia. According to this theory, it seems appropriate to begin the treatment with the restoration of binocular vision, which also leads to the restoration of the vision of the amblyopic eye. Poor visual functions in amblyopia is associated with the presence of suppression in binocular conditions of vision. Suppression transforms the structurally binocular system functionally monocular. Therefore, the first and most important step to restore binocular vision should be considered the elimination of suppression. The quantification of suppression is a critically important step for the improvement of new therapies for amblyopia based on the global perception of movement associated with the function of the dorsal extrastriate visual cortex. This new understanding of amblyopia now becomes the basis for carrying out a large volume of diverse studies that provide the development of more effective therapies that will primarily focus on eliminating suppression and restoring binocular vision.

弱视的双眼相互作用。
本文综述了目前文献中关于弱视发育机制的一些新观点。客观证据表明,弱视在视觉加工过程中同时影响单眼和双眼功能。鉴于越来越多的基础和临床研究证据,双眼功能障碍很可能是原发的,单眼视力下降是继发的。弱视是双眼而非单眼的病变,双眼相互作用似乎在斜视、屈光参差和混合型弱视的发病机制中起关键作用。根据这一理论,从恢复双眼视力开始治疗似乎是合适的,这也会导致弱视视力的恢复。弱视的视觉功能低下与双眼视力的抑制有关。抑制将结构上的双目系统转变为单眼系统。因此,恢复双眼视力的第一步和最重要的一步应考虑消除抑制。基于与背侧纹外视觉皮层功能相关的整体运动感知,抑制的量化是改善弱视新疗法的关键一步。这种对弱视的新认识现在成为开展大量不同研究的基础,这些研究提供了更有效的治疗方法,主要集中在消除抑制和恢复双眼视力。
