Examination of 113 eyes vital-stained by Sudan powder revealed that fat on the skin of outer canthus may pass onto the precorneal film (in 68%), and that the most reliable staining is obtained by application on the bulbar conjunctiva below the limbus corneae at 6 o'clock. In 41%, the precorneal film had stained drops or foam, with a tendency towards an increase among pathological cases (infectious conjunctivitis and blepharitis). An increased amount of fat was found in the mucous thread of eyes affected with infectious conjunctivitis and lagophthalmos. In a small number of pathological cases fat was also detected on cornea, bulbar conjunctiva, and inferior fornix. The fatty layer on the lower lid margin was stained more frequently and more intensely than that on the superior. The secretion of the meibomian glands was stained in no more than a scant one half of the glands (on an average 44%), independently of age, sex, site, and diagnosis.
对113只经苏丹粉活体染色的眼睛进行检查发现，外眦皮肤上的脂肪可能会转移到角膜前膜上（68%），最可靠的染色方法是在角膜缘6点处下方的球结膜上涂抹。41%的角膜前膜有染色的液滴或泡沫，在病理病例（感染性结膜炎和睑缘炎）中有增加的趋势。在感染性结膜炎和兔眼症患者的眼黏液丝中发现脂肪量增加。在少数病理病例中，角膜、球结膜和下穹窿也检测到脂肪。下睑缘的脂肪层比上睑缘的脂肪层染色更频繁、更强烈。睑板腺的分泌物染色的腺体不超过一半（平均44%），与年龄、性别、部位和诊断无关。
