OCT在弱视患者眼底研究中的应用

弱视是一种常见的儿童眼部疾病，如未进行及时的矫正与治疗，将对儿童视力造成不可逆的损伤，导致单眼或双眼视力下降或丧失。弱视的发病原因复杂，目前具体发病机制尚不明确，主要集中于中枢学说与外周学说，既往传统观念认为弱视患者眼底无明显器质性改变。近年来光学相干断层扫描(OCT)技术迅速发展，作为一种便捷、直观的眼科检查手段，其安全无创、非接触性及快速清晰的优点，使OCT越来越多地应用于弱视患者的视网膜检查，弱视患者眼底结构存在的异常解剖学结构也逐渐被发现，为弱视的外周学说发病机制提供一定佐证和依据，对弱视的检查、治疗评估和预后也起到一定作用，本文对OCT技术对弱视患者视网膜厚度、脉络膜厚度及血管密度的研究情况进行综述。

Application of OCT in the research of amblyopic fundus

Amblyopia is a common eye disease in children. If not corrected and treated in time, it will cause irreversible damage to children''s vision, resulting in loss of vision in one or both eyes. The pathogenesis of amblyopia is complex, and the specific pathogenesis is not clear at present, mainly focusing on the central theory and peripheral theory. Traditionally, there was no obvious organic change in the fundus of amblyopia patients. In recent years, optical coherence tomography(OCT)technology has developed rapidly. As a convenient and intuitive ophthalmic examination method, OCT has been increasingly used in retinal examination of amblyopia patients due to its advantages of safety, non-invasive, non-contact and rapid and clear. The abnormal anatomy structures of the amblyopia patients in fundus structure are also gradually been found. Providing some evidence and basis for peripheral theory of pathogenesis of amblyopia, amblyopia examine, postoperative evaluation and prognosis. In this article, the applications of OCT in retinal thickness, choroid thickness and vessel density are reviewed.
