Twenty-two eyes affected with keratoconjunctivitis sicca have been subjected to double trials using the double-blind randomized cross-over technique. Polyvinyl alcohol in a 5% concentration improved the condition whereas liquid paraffin aggravated it, as estimated subjectively, and by the measurement of the break up time of the corneal film, and, finally, by the scoring of rose bengal vital staining of exposed cornea and conjunctiva. The conclusion is drawn that oil is contraindicated in keratoconjunctivitis sicca, and that rose bengal scoring (modified Bijsterveld method) is a valuable aid in control of the sicca syndrome.
对22只患有干燥性角结膜炎的眼睛采用双盲随机交叉技术进行了双试验。主观评估、测量角膜膜破裂时间以及最后对暴露的角膜和结膜进行孟加拉玫瑰红活体染色评分结果显示，5%浓度的聚乙烯醇可改善病情，而液体石蜡则会加重病情。得出的结论是，干燥性角结膜炎禁用油性药物，并且孟加拉玫瑰红评分（改良的比斯特费尔德方法）有助于控制干燥综合征。
