背景/目的驾驶员在双目视觉下没有意识到自己的视野(VF)缺陷而导致的汽车事故已经成为一个问题。我们开发了一种简单的自查表(钟表双目版(CCBE))，帮助青光眼患者识别他们的双眼室颤异常，并评估其有效性。考生将图表逐渐顺时针旋转360度。在每30°时，受试者确认注视，并指示是否可以看到所有四个目标。青光眼患者44例88眼，平均年龄64.4±13.1岁；视力正常者32例眼，平均年龄32.0±8.4岁。除CCBE测试外，对青光眼患者还采用瑞典交互阈值算法-标准30-2和双眼Esterman程序进行静态VF测试。结果VF异常定义为中心30°内两个或两个以上邻接点，其灵敏度为<；10 分贝。CCBE试验对HFA和Esterman结果的敏感性分别为85%和82%。我们还对第一组(汽车/摩托车)司机使用了英国的VF标准，CCBE的灵敏度为88%。该表对视力正常的受试者具有100%的特异度。结论CCBE测试使青光眼司机在双眼状态下能够注意到他们的VF异常。这种简单的自查方法在驾驶执照等场合的应用似乎很有前景。
Background/aimsCar accidents caused by drivers unaware of their visual field (VF) defects under binocular vision have become an issue. We developed a simple self-check chart (CLOCK CHART binocular edition (CCBE)) to help patients with glaucoma recognise their abnormalities in the binocular VF and evaluated its usefulness.MethodsThe chart has four targets displayed at 10°, 15°, 20° and 25° eccentricities. The examinee gradually rotates the chart 360° clockwise. At every 30°, the examinee confirms the fixation and indicates if all four targets can be seen. This study enrolled 88 eyes of 44 patients with glaucoma (mean age, 64.4±13.1 years) and 64 eyes of 32 visually normal individuals (mean age, 32.0±8.4 years). Except the CCBE test, static VF testing using the Humphrey field analyser (HFA) Swedish Interactive Threshold Algorithm-Standard 30-2 and binocular Esterman programmes was also performed for the subjects with glaucoma.ResultsVF abnormality was defined as two or more contiguous points with a sensitivity of <10 dB within the central 30°. The CCBE test had sensitivities of 85% and 82% with respect to the HFA and Esterman results, respectively. We also used the British VF standards for Group 1 (car/motorcycle) drivers, and a sensitivity of 88% was obtained for the CCBE. The chart had a specificity of 100% for the visually normal subjects.ConclusionThe CCBE test enables drivers with glaucoma to notice their VF abnormalities under binocular condition. The application of this simple self-check method appears promising for occasions such as driver licensing.
