To study the usefulness of ocular torsion analysis as an adjunct to examining central vestibular compensation.
Prospective evaluation.

Seven patients with intractable Meniere's disease underwent elective transtympanic gentamycin labyrinthectomy. Serial examination of patient progress was performed using fundus photography, subjective visual vertical estimations, electronystagmography, and audiometry.
Ocular torsion analysis reveals unexpected initial and early contraversive torsion behaviour in some patients, which may represent an early irritative phenomenon stemming from either the gentamicin or the Meniere's disease itself.
Despite the sensitivity of the ocular torsion measures, there appears to be no useful predictive correlation between ocular torsion and audiometric functioning that might predict impending hearing loss. Nevertheless, ocular torsion analysis reveals subtle changes in vestibular system functioning and may provide useful adjunctive information in the assessment of vestibular ototoxicity.
研究眼扭转分析作为检查中枢前庭代偿辅助手段的效用。

7例难治性梅尼埃病患者接受了择期经鼓膜庆大霉素迷路切除术。使用眼底摄影、主观视觉垂直估计、眼震电图和听力测定对患者进展进行系列检查。
眼扭转分析显示，部分患者出现意外的初始及早期反向扭转行为，这可能代表了源自庆大霉素或梅尼埃病本身的早期刺激性现象。
尽管眼扭转测量具有敏感性，但眼扭转与听力功能之间似乎不存在可预测即将发生听力损失的有用预测相关性。然而，眼扭转分析揭示了前庭系统功能的细微变化，并可能在评估前庭耳毒性时提供有用的辅助信息。
