光应激时试验是检查眼底黄斑功能的常用方法,但近年有些学者发现青光眼光应激时较正常人明显延长,而且这一改变出现在视野变化之前。本文对32例开角青光眼进行光应激时测定并加以讨论。我们对已确诊开角青光眼随访患者随机选择32例,64只眼,年龄16～61岁,平均51岁。测试时药物控制眼压在正常范围,其中39只眼视野有改变。另外我院健康医护人员,共30名,60只眼,年龄30～56岁,平均49岁,眼压正常,无任何眼病者作为对照组。两组均采用国际视力表检查远视力,如有屈光不正给予镜片矫正。所测的最好视力做为基础视力,然后用不透光眼罩遮盖左眼,用苏州产Yz-2型交流电眼底镜中光斑置右眼前2～3cm照射10秒后立即撤光,测定视刀恢复到照射
Light stress test is to check the macular function of the common method, but in recent years some scholars have found that glaucoma light stress was significantly longer than normal, and this change appears in the visual field before the change. In this paper, 32 cases of open-angle glaucoma were measured and discussed during light stress. We randomly selected 32 patients, 64 eyes, aged 16 to 61 years with an average of 51 years of age. Test control of intraocular pressure in the normal range of drugs, of which 39 eyes have changed field of vision. In addition, our hospital health care workers, a total of 30, 60 eyes, aged 30 to 56 years, mean 49 years, normal IOP without any eye disease as a control group. Both groups were using the international visual acuity chart to check the distance vision, if refractive errors were given lens correction. The best visual acuity measured as the basis of vision, and then cover the left eye with opaque goggles, ophthalmic Yz-2 produced in Suzhou ophthalmic ophthalmic fundus in the right eye 2 ~ 3cm 10 seconds immediately after irradiation retreated, measured by the knife Revert to irradiation
