Foam in the external part of the eye has been measured at the slit-lamp on 274 normal subjects. Foam occurred in 78%, most frequently in the outer canthus, on the skin round this, and in the lateral half of the lid margin. The age group of 30-50 years predominated. The foam-covered areas averaged 1.1 mm2, the largest amount always being found laterally (0.93 mm2). The lateral amount of foam was maximal in the age group of 30-50 years, while the medial maximum was seen in the age group of 60-70 years. The incidence of foam was not correlated to the lipid layer on the precorneal film, expressibility of Meibomian secretion, scales on the lid margin, or greasy hair. A hypothesis has been advanced for the mainly lateral position of the foam: blinking whips up the foam, which possibly has sebum admixed.
在裂隙灯下对274名正常受试者的眼外部泡沫进行了测量。78%的受试者出现了泡沫，最常见于外眦、其周围皮肤以及睑缘外侧半。30至50岁年龄组占主导。泡沫覆盖面积平均为1.1平方毫米，最大量总是出现在外侧（0.93平方毫米）。外侧泡沫量在30至50岁年龄组中最大，而内侧最大值出现在60至70岁年龄组。泡沫的发生率与角膜前膜上的脂质层、睑板腺分泌的可挤压性、睑缘鳞屑或油性头发无关。针对泡沫主要位于外侧的情况提出了一种假说：眨眼会激起泡沫，而泡沫中可能混有皮脂。
