视觉倒置(upside-down reversal of vision,UDRV)是一种罕见的视物变形症或视觉错觉,能扭曲物体的大小、形状或倾斜程度的临床症状.其特征是患者的视觉图像在冠状位发生瞬时 180°的倒置.迄今为止,UDRV在国内尚未见报道,但在国外文献的报道中,其严重影响患者视力和生活,给患者的心理带来了前所未有的冲击.本文讨论UDRV的潜在病因和临床特征,以期进一步提高临床医生对这种情况的认识,科学诊断和治疗,减少患者的心理困扰.尽管现有的UDRV研究有助于了解视觉形成的机制和可能的视觉调节机制,但具体的病因和机制尚不清楚.因此我们提出了一个视觉调控的假说"视觉独立调控中枢"来解释这种现象.
Upside-down reversal of vision(UDRV)is a rare clinica symptom of visual distortion or visual illusion that can distort the size,shape,or tilt of an object.Its characteristic is that the patient's visual image undergoes an instantaneous 180° inversion in the coronal position.So far,UDRV has not been reported in China,but in foreign literature,it seriously affects patients'vision and life,bringing unprecedented psychological impact to patients.Here,we discuss the potential etiology and clinical features of UDRV to further improve the understanding of this condition by clinicians,scientifically diagnose and treat the condition,and reduce the psychological distress of patients.Although existing studies on UDRV help us understand the mechanisms of vision formation and possible regulatory mechanisms of vision,the specific etiology and mechanisms are not yet clear.Therefore we propose a hypothesis of visual regulation:"visual-independent regulation center"to explain it.
