概括

视力缺陷在急性缺血性中风 (AIS) 后持续数月,影响噪音和视野中的视力敏度. 早期和持续的视力评估对于中风恢复和康复至关重要.

科学领域:

神经科学是一个神经科学.
眼科医生眼科眼科
神经学神经学

背景情况:

视力缺陷很常见,但在急性缺血性中风 (AIS) 后被低估.
之前的研究表明,在住院几天内,~68%的AIS患者出现显著的视觉功能缺陷.
本研究的重点是评估AIS后2-6个月的视力恢复.

研究的目的:

评估在经历轻度至中度急性缺血性中风 (AIS) 的患者视觉功能的恢复.
识别持续的视力缺陷及其与中风特征和病变位置的相关性.

主要方法:

在AIS后的第一周和2-6个月内,在iPad上进行视觉评估 (视觉敏度,VA-in-noise,视野,忽视,眼手协调).
结果与20个年龄相匹配的健康对照进行了比较.
记录了病变和手的优势的放射性确认.

主要成果:

最初,95%的患者视力敏度正常,但55%的患者视力敏度降低. 80%的人有视野缺陷,往往没有被注意到.
2-6个月后,视觉注意力正常化,但15%的人仍然减少了VA-in-noise,而35%的人保留了视野缺陷.
视觉运动障碍在40%的患者中持续存在,后部循环和左半球中风与持续的缺陷有关.

结论:

轻度急性缺血性中风 (AIS) 可以导致持续的视觉和视觉运动障碍.
对于中风患者来说,常规和纵向视力评估对于指导康复和评估驾驶适用性至关重要.
识别这些缺陷有助于优化中风幸存者的康复和功能结果.

Visual Agnosia

Visual Agnosia

Visual agnosia is a condition characterized by the inability to recognize visually presented objects despite having normal vision. For instance, a person with visual agnosia can describe the shape and color of an object but cannot identify or name it. This impairment does not affect their visual field, acuity, color vision, brightness discrimination, language, or memory. An example of this condition in a social setting is someone at a dinner party asking for "that silver thing with a round...

Prosopagnosia

Prosopagnosia

Prosopagnosia, also known as face blindness, is the inability to recognize faces. In severe cases, individuals with prosopagnosia may not recognize close family members, including parents and spouses, by their faces. For instance, someone with prosopagnosia might walk past their child in a crowd, only realizing their mistake upon noticing their child's distinctive backpack or favorite jacket. Prosopagnosia specifically impairs facial recognition, while the recognition of other objects or...
