‘Photopsia’ describes the symptom of visual disturbances that are typically flash-like, sudden in onset and brief, and occurring without light entering the eye. Patients reporting photopsia often pose a diagnostic challenge, given the wide range of possible neurological and ophthalmological causes. We review the common causes of photopsia, discuss the assessment and workup of this symptom, and stress the importance of close interdisciplinary liaison to help with its diagnosis and management. We discuss a patient with acute zonal occult outer retinopathy to illustrate these points.

视觉幻觉

“幻视”描述了视觉障碍的症状，这些症状通常像闪光一样，突然发作且短暂，并且在没有光线进入眼睛的情况下发生。鉴于可能的神经和眼科原因范围广泛，报告闪光感的患者通常构成诊断挑战。我们回顾了眩光的常见原因，讨论了该症状的评估和检查，并强调了密切跨学科联系以帮助其诊断和管理的重要性。我们讨论了一个患有急性带状隐匿性外层视网膜病变的患者来说明这些观点。
