摘要169名非选择的1-5岁儿童（338只眼）通过双闪光照相机和自动对焦相机筛查斜视、高度屈光参差和高度屈光不正，无睫状肌麻痹。由护士或技术人员进行摄影，并由配镜师分析照片。用光学演示眼测试了该方法对屈光不正的灵敏度。调查结果：5例内斜视，1例外斜视，1例4屈光度的直视远视性屈光参差; 1例双眼假阳性高度远视（+2.5屈光度）。照片检查显示33例（66只眼; 19.5%）轻度屈光不正：其中2例为-1.0和-1.75D的对称性近视，31例为+0.25至+4.25D的对称性远视。128例（256眼）正常。其中，对37例非选择病例（74只眼）进行了临床检查，视网膜检影检查显示为-1.0至+3.25屈光度的对称病例。对照组无假阴性病例。2.4%的照片在技术上失败或由于儿童的不合作。由技术人员或护士进行的双闪光照相检查为婴儿斜视和/或屈光不正导致弱视的大规模筛查提供了一种有价值的工具。
Abstract 169 non‐selected 1–5 year‐old children (338 eyes) were screened by two‐flash photoskiascopy with an autofocus camera for strabismus, high anisometropia and high ametropias without cycloplegia. The photography was performed by nurses or technicians and the photographs were analyzed by an optician. The sensitivity of the method for the refractive errors was tested with an optical demonstration eye. Findings: 5 esotropias, 1 exotropia, 1 straight‐eyed hypermetropic anisometropia of 4 diopters; 1 false positive high hyperopia (of +2.5 diopters) of both eyes. The examination of the photographs showed slight refractive errors in 33 cases (66 eyes; 19.5%): two of them of symmetrical myopia of ‐1.0 and ‐1.75 diopters and 31 of symmetrical hyperopia of +0.25 to +4.25 diopters in rhinoscopy. 128 cases (256 eyes; 76%) were normal on the photographs. Of these, 37 non‐selected cases (74 eyes) were checked clinically and were symmetrical cases of ‐1.0 to +3.25 diopters on retinoscopy. No false negative cases appeared among these control cases. 2,4% of the photographs failed technically or because of non‐cooperation of the children. Two‐flash photoskiascopy, performed by technicians or nurses provides a valuable tool for mass screening of infants for strabismus and/or ametropia causing amblyopia.
