RESULTS: VS/VSS may be primary or secondary to a variety of etiologies, including ophthalmologic or brain disorders, systemic disease, and medication/hallucinogen exposure. Evaluation involves ruling out secondary causes and mimics of VS. Increasing evidence suggests that VSS is a widespread process extending beyond the visual system. Pathophysiology may involve cortical hyperexcitability or dysfunctional connectivity of thalamocortical or attention/salience networks. VSS is typically a benign, non-progressive syndrome and can be managed with non-medicine strategies. Though no medication provides complete relief, some may provide partial improvement in severity of VS.
结果:VS/VSS可能是各种病因的原发性或继发性,包括眼科或脑部疾病,全身性疾病,和药物/致幻剂暴露。评估涉及排除VS的次要原因和模仿。越来越多的证据表明,VSS是一个超越视觉系统的广泛过程。病理生理学可能涉及皮质兴奋过度或丘脑皮质或注意力/显着性网络的功能异常连接。VSS通常是良性的,非进展综合征,可以用非医学策略管理。虽然没有药物可以完全缓解,一些可以提供部分改善VS的严重程度。
