Both peripheral displacement thresholds and measurement of optic disc parameters have been advocated in the early diagnosis of glaucoma at the stage before scotomata are detected on conventional visual field assessment. The peripheral movement displacement thresholds were measured in 50 eyes of 50 patients with ocular hypertension and a significant correlation was found with neuroretinal rim areas measured using a computerised image system. There was also a significant correlation with optic disc diameter but no correlation with cup-disc ratio. The results support the proposition that measurement of peripheral movement displacement thresholds may be a useful tool in the detection of early glaucomatous optic nerve damage.
在常规视野评估检测到暗点之前的青光眼早期诊断中,周边位移阈值和视盘参数测量均得到了提倡。对50例高眼压症患者的50只眼睛测量了周边运动位移阈值,发现其与使用计算机图像系统测量的神经视网膜边缘面积存在显著相关性。与视盘直径也存在显著相关性,但与杯盘比无相关性。结果支持这样的观点,即周边运动位移阈值测量可能是检测早期青光眼性视神经损伤的有用工具。
