We measured the corneal thickness in 24 eyes of 12 healthy females aged between 19 and 29 years. Ultrasonic pachometer was used throughout. Pre-liminary measurements of the corneal thickness were conducted from 8 o'clock in the morning till 8 o'clock in the evening at an 2-hour interval. We could observe the presence of diurnal rhythmical fluctuation in the corneal thickness. In the majorityof cases, the corneal thickness attained the mini-mum value at 4 pm.

We then measured the corneal thickness between 4 and 5 pm, 3 times a week for up to 2 months. The corneal thickness increased for one week after ovulation and then started to decrease till the onset of menstruation. The finding indicates that the corneal thickness changes along with the menstrual cycle, probably due to the influence by sex hor-mones.
