一些眼病包括与年龄有关的黄斑变性,高血压性视网膜病变,裂孔源性视网膜脱离,萄葡膜炎和慢性开角型青光眼等的患病率和严重性已知是具有种族的差异。在开角型青光眼中,黑种人似乎比白种人更为普遍,更具侵害性。而且发病年龄也比白种人要早。为了明确某些解剖因素对青光眼性损害是否有诱发的关系,作者等对眼部正常的30名(20名白种人,10名黑种人)自愿者的医学生进行了视盘大小测量的前瞻性研究。病人和方法:视盘水平和垂直直径的测量是使用一个有十字线的12倍放大镜刻尺测量,误差为0.02mm,采用柯达彩色胶卷,用Zeiss
The prevalence and severity of some eye diseases, including age-related macular degeneration, hypertensive retinopathy, riparian retinal detachment, grapevitis and chronic open-angle glaucoma, are known to be racially different. In open-angle glaucoma, blacks appear to be more common and invasive than Caucasians. And the age of onset than the white earlier. To clarify whether some anatomical factors have an evoked association with glaucomatous lesions, the authors looked at the size of the optic disc in medical students with 30 normal volunteers (20 white, 10 black) volunteers Sexual research. Patients and Methods: The horizontal and vertical diameters of the optic disc were measured using a 12x magnifying glass ruler with an error of 0.02 mm using Kodak color film with Zeiss
