Abstract
- 59 males and females were tested for the purpose of measuring the basic lacrimation under topical anesthesia of cornea and conjunctiva with 0.5% pontocaine using Toyo No.5 filter paper of 4.5 X 35mm in size. The total mean is 1.52mm/min and the means of male and female are 1.65mm/min and 1.37mm/min respectively. The mean of persons under 30 years of age is 1.68mm/min and that of over 30 years is 1.31mm/min. The means of male and female under 30 years of age are 2.12mm/min and 1.16mm/min and those of over 30 years are 1.01mm/min and 1.60mm/min respectively. The difference between means under 30 years and that of over 30 years in male is statistically significant but other differences are statistically not significant. The difference between auther's and other's values is, I suppose, derived partly from different filter paper used, and smallness of the number of person is another factor influenced.
