Visual modulation of the vestibulo-ocular reflex (VOR) was analyzed in 16 patients with non-neurologic Behçet's disease who had no manifest vestibular or ocular-motor symptoms. The VOR gains in the darkness were elevated in 63% of the patients. The elevated gain in the darkness was not attributed with certainty to vestibular adaptation to defective smooth pursuit, because only 25% of the patients manifested impaired smooth pursuit eye movements. Visual impairment occurred in some patients but did not correlate with the VOR elevation. An unknown mechanism affecting the vestibular system has been considered. The VOR elevation in the darkness may suggest the presence of a latent brainstem abnormality in the patients.
对16例无明显前庭或眼动症状的非神经型白塞病患者的前庭眼反射（VOR）视觉调节进行了分析。63%的患者在黑暗中的VOR增益升高。黑暗中增益升高不能确定归因于前庭对缺陷性平稳跟踪的适应，因为只有25%的患者表现出平稳跟踪眼动受损。一些患者出现了视力损害，但与VOR升高无关。已考虑存在影响前庭系统的未知机制。黑暗中VOR升高可能提示患者存在潜在的脑干异常。
