title: A simple photogrammetric method of measuring anterior chamber volume.
abstract: We devised a convenient method of measuring anterior chamber volume in man. Photographs of the anterior chamber were taken with a Zeiss photographic slit lamp with a Polaroid attachment, and measured with a specially constructed transparent scale. Using this method, the standard deviation of individual measurements of volume on different occasions in a given eye was 8 microliter. The standard deviation of the differences between right and left eyes of normal subjects was 10 microliter. The volume of the anterior chamber measured in 78 eyes of 39 normal subjects (mean age, 28 years; range, 19 to 56 years) was found to be 209 +/- 37 microliter (mean +/- SD). We observed a small negative correlation between the age of the subject and the volume of the anterior chamber.
