Report of an examination of 127 Arabs in the Red Sea City of Aqaba, Jordan. The results are compared with those of the author's examinations, using a similar apparatus, of 659 Eskimos in Western Greenland and 810 Caucasians in Copenhagen. Ultraviolet (u.v.) light is at a maximum in the Red Sea territory, considerable in Greenland, and negligible in Copenhagen. The prevalences of the following degenerative processes are high at the Red Sea, somewhat lower in Greenland, and low in Copenhagen: Climato-keratopathy gr. III (across the cornea, often with autofluorescent spheroids, always with conjunctival location as well), conjunctival spheroids (39%), and pinguecula (90% at the Red Sea). The prevalence of the conjunctival spheroid degeneration greatly exceeds that of the corneal. No difference is demonstrable between tropical and arctic keratopathy. The investigations performed gave results bearing out the view that u.v. light is responsible for all the above degenerative processes. Pterygium is equally frequent at the Red Sea and in Greenland. Lipid deposits (6%) and scleral plaques are not more prevalent at the Red Sea, a fact which argues against an ultraviolet genesis.
约旦红海城市亚喀巴127名阿拉伯人的检查报告。将结果与作者使用类似设备对西格陵兰岛659名爱斯基摩人和哥本哈根810名高加索人进行检查的结果进行了比较。紫外线在红海地区强度最大，在格陵兰岛相当可观，而在哥本哈根则可忽略不计。以下退行性病变的患病率在红海地区较高，在格陵兰岛略低，在哥本哈根较低：III级气候性角膜病变（横跨角膜，常伴有自发荧光球体，结膜部位也总是存在）、结膜球体（39%）和睑裂斑（红海地区为90%）。结膜球体变性的患病率大大超过角膜的患病率。热带和北极角膜病变之间没有明显差异。所进行的调查结果支持紫外线是上述所有退行性病变原因的观点。翼状胬肉在红海地区和格陵兰岛同样常见。脂质沉积（6%）和巩膜斑块在红海地区并不更普遍，这一事实与紫外线成因相悖。
