摘要
中心视力下降是导致老年性黄斑变性等疾病患者对比敏感度、色觉等视功能下降的主要原因.研究发现中心视力下降患者在中心凹外视网膜功能相对较好位置可形成新的视觉任务区域,称之为优选注视点.本文综述了利用微视野仪进行视网膜最佳注视点定位和首选视网膜位点训练的相关文献,总结了目前的研究现状和不足.本文旨在对中枢性视力丧失患者视力状况的研究进行综述,为中枢性视力丧失患者视力康复方案的选择提供帮助.
Abstract
Low central visual acuity is mainly caused by decreases or deficiencies in contrast sensitivity,color vision,and other vis-ual functions in patients with age-related macular degeneration.Studies have found that patients with central visual acuity loss can form a new visual task area,called the preferred retinal locus,at a relatively good position outside the foveal retina.In this paper,relevant articles about the optimal fixation point location and the training of the preferred retinal locus using microvisual field instru-ments are reviewed,and the current research status and shortcomings are summarized.The purpose of this paper is to review the pro-gress of research on the visual condition of patients with central vision loss and to provide information that will aid the selection of visual rehabilitation programs for such patients.
