目的：研究中风后视觉症状的频率和类型。设计：前瞻性多中心队列研究方法：采用标准化转诊/调查方案，详细评估视力、眼球排列/运动、视野和视知觉，加上生活质量评分。结果：共招募了915例患者，平均年龄为69.18岁（标准差14.19）。报告的症状包括复视、视物模糊、阅读困难、视野丧失、知觉困难和视物模糊。百分之十六（149）没有视觉症状：22例患者通过正视评估进行了正常的眼部检查，127例诊断为中心/周边视力丧失、眼球运动或知觉异常。84%的患者有视觉症状，但50名患者的眼科检查正常。两组患者的症状类型及生活质量评分差异无统计学意义。治疗包括屈光，棱镜，闭塞，正视练习，低视力aids，和advice.Conclusions：那些没有视觉症状，85%的客观测量视力损害。相反，6.5%有视觉症状的人有正常的正视检查。因此，视觉症状的存在或不存在并不意味着视觉障碍的存在或不存在，并且可能与视觉障碍、认知或沟通障碍的恢复有关。
Aim: Investigate the frequency and type of visual symptoms following stroke.Design: Prospective multicenter cohort study (Vision in Stroke [VIS]) in accordance with Declaration of Helsinki.Methods: Standardized referral/investigation protocol with detailed assessment of visual acuity, ocular alignment/ motility, visual field and visual perception, plus quality of life score.Results: A total of 915 patients were recruited with a mean age of 69.18 years (standard deviation 14.19). Reported symptoms included diplopia, blurred vision, reading difficulty, field loss, perceptual difficulty, and oscillopsia. Sixteen percent (149) had no visual symptoms: 22 patients had normal eye examinations by orthoptic assessment and 127 had diagnoses of central/ peripheral visual loss, ocular motility or perceptual abnormalities. Eighty-four percent had visual symptoms, but 50 patients had normal eye examinations. There was no significant difference in type of symptom and quality of life score. Treatment included refraction, prisms, occlusion, orthoptic exercises, low vision aids, and advice.Conclusions: Of those with no visual symptoms, 85% had objectively measured visual impairment. Conversely, 6.5% of those with visual symptoms had normal orthoptic examinations. Thus the presence or absence of visual symptoms does not infer absence or presence of visual impairment and may relate to recovery of visual impairment, cognitive, or communication impairment.
