The aim of this study was to compare an automated confrontation visual field testing (ACV) device with traditional finger-counting confrontation visual field testing (FCV).
Forty-five eyes of 45 subjects with glaucoma, 5 eyes of 5 subjects with neurologic disease and 15 eyes of 15 normal subjects (age matched to the subjects with glaucoma by frequency) were tested on both ACV and FCV. All subjects with glaucoma and neurologic disease had visual field loss on white-on-white Humphrey perimetry (HVF). The FCV was performed in 8 meridians in a normally lighted room, whereas ACV was performed in a darkened room. The ACV device consisted of a black rectangular box with 4 1.0-mm red light-emitting diodes at each corner and a fixation hole at the center. Four automated randomized presentations were presented, and the subject was asked to identify the number of red lights seen (from 1 to 4). Any point missed on any of the presentations on either test was recorded as a failure.
All normal subjects passed both tests. FCV detected field loss in 33.0% of glaucomatous eyes, whereas ACV detected field loss in 58% of glaucomatous eyes (P < 0.001). Subjects with glaucoma who passed FCV but failed ACV had an average mean deviation of -7.77 dB on HVF, compared with subjects who failed both FCV and ACV, who had an average mean deviation of -19.74 dB on HVF (P < 0.001). All subjects with absolute visual field loss because of advanced glaucoma or neurologic disease failed both tests. No subject who passed ACV failed FCV.
Gross confrontation visual field testing using an automated testing device has a greater sensitivity in the detection of moderate visual field loss than finger counting confrontation visual fields.
本研究旨在比较自动对照视野测试（ACV）设备与传统手指计数对照视野测试（FCV）。
对45例青光眼患者的45只眼、5例神经系统疾病患者的5只眼以及15例正常受试者（年龄与青光眼患者按频率匹配）的15只眼进行了ACV和FCV测试。所有青光眼和神经系统疾病患者在白色对白色的Humphrey视野计（HVF）检查中均有视野缺损。FCV在正常照明房间的8个子午线上进行，而ACV在暗室中进行。ACV设备由一个黑色矩形盒子组成，每个角有4个1.0毫米的红色发光二极管，中心有一个固定孔。进行了四次自动随机呈现，要求受试者识别看到的红灯数量（从1到4）。任何一次测试中任何一次呈现遗漏的任何点都记录为失败。
所有正常受试者两项测试均通过。FCV检测到33.0%的青光眼眼中有视野缺损，而ACV检测到58%的青光眼眼中有视野缺损（P<0.001）。通过FCV但ACV测试失败的青光眼患者在HVF上的平均平均偏差为-7.77 dB，而FCV和ACV测试均失败的患者在HVF上的平均平均偏差为-19.74 dB（P<0.001）。所有因晚期青光眼或神经系统疾病导致绝对视野缺损的受试者两项测试均失败。通过ACV测试的受试者没有FCV测试失败的情况。
使用自动测试设备进行的粗略对照视野测试在检测中度视野缺损方面比手指计数对照视野测试具有更高的灵敏度。
