Patients with functional vision disorder (FVD) may present with poor visual acuity, visual field loss, or a combination of the two. This paper illustrates the utility of objective tests in diagnosing FVD. We use sweep visual evoked potentials and eye tracking as objective tests for visual acuity and visual field, respectively. These measurements should be made early in the diagnostic process because appropriate treatment becomes more difficult the longer the patient has been undergoing medical workups and referrals. Additionally, objective proof of better visual functions can be used as confirmation of the absence of a serious organic disorder. The results are used to convince patients and parents that vision is potentially much better than the patient experiences and to explain FVD. Consultation should preferably take place in a multidisciplinary setting with trained ophthalmologists and psychologists.
功能性视力障碍（FVD）患者可能表现为视力差、视野缺损或两者兼有。本文阐述了客观测试在诊断FVD中的作用。我们分别使用扫描视觉诱发电位和眼动追踪作为视力和视野的客观测试。这些测量应在诊断过程早期进行，因为患者接受医学检查和转诊的时间越长，进行适当治疗就越困难。此外，视觉功能更好的客观证据可用于证实不存在严重的器质性疾病。这些结果用于让患者和家长相信其视力可能比患者自身感受要好得多，并解释FVD。咨询最好在多学科环境中由训练有素的眼科医生和心理学家进行。
