摘要 目的建立配戴框架眼镜时周边屈光的测量系统及方法,并检验其有效性,评估其可靠性。方法以Grand Seiko WAM-5500型自动验光仪为基础,将头托替换为自制的视角选择固定装置,增加弧形游动视标架,作为周边屈光的测量系统。并按照光路追迹原理搭建装置,测量框架眼镜周边部光线偏折引起的测量角度补偿量。使用上述改装的系统和角度校正方法测量35名近视者配戴框架眼镜时视网膜黄斑中心凹和鼻、颞侧偏离中央凹10°、20°、30°水平方向上7个点的屈光状态。并另招募35名近视者作为对照组,采用传统方法测量其裸眼状态时上述7个点的屈光度。比较两种方法测量值标准差的差异,评估其可靠性。结果①该系统和方法测量配戴框架眼镜时周边屈光的所得值标准差与传统测量方法所得值标准差的差异无统计学意义(P〉0.05),说明其可靠性较好;②近视者框架眼镜矫正下视网膜周边部呈远视性离焦。结论本系统及方法用于屈光不正患者框架眼镜矫正下的周边屈光测量具有良好的可靠性和有效性。 Objective To establish a systematic specified measurement for peripheral refraction in myopic eyes under spectacle correction. Methods A peripheral refractive measurement system was established based on the Grand Seiko WAM-5500 autorefractor. An accessory with a modified visual angle device was used to replace the headrest. A ray-tracing method was used for determining the offset of the visual field angle. Using this system and technique, peripheral refraction was measured at 7 different points at 10° intervals over the central ±30° of the horizontal visual field on 35 myopic subjects under spectacle correction conditions. The same measurement for peripheral refraction was also taken on another 35 myopic subjects (control group) under uncorrected conditions by using the unmodified system. The reliability of the system and technique were analyzed by using an independent samples t-test. Results This system and technique were effective for measuring peripheral refraction in myopes under spectacle correction. The reliability of this method was in compliance with traditional methods for measuring peripheral refraction under spectacle correction (P〉 0.05). Peripheral refractions were more hyperopic than that of the fovea in myopic subjects under spectacle correction. Conclusion This system and technique are effective and reliable for measuring peripheral refraction in myopic eyes under spectacle correction.
