Corneal sensitivity was determined in 5 women with regular menstrual cycles by means of a new aesthesiometer developed by Dräger. Throughout one menstrual cycle we measured corneal touch thresholds (CTT) daily and did serial determinations of urinary luteinising hormone and pregnanediol levels. CTT rose in 4 women with proved ovulation in the days before or on the day of ovulation, while corneal sensitivity remained unchanged in one anovulatory subject. We observed no changes in CTT prior to menstruation. The decrease in corneal sensitivity might be related to the preovulatory oestrogen peak.
通过Dräger公司研发的新型麻醉测量仪，对5名月经周期规律的女性进行了角膜敏感度测定。在一个月经周期内，我们每天测量角膜接触阈值（CTT），并连续测定尿促黄体生成素和孕二醇水平。在4名已证实排卵的女性中，CTT在排卵前或排卵当天升高，而在一名无排卵的受试者中，角膜敏感度保持不变。我们观察到月经前CTT没有变化。角膜敏感度的降低可能与排卵前雌激素高峰有关。
