“…He found the standard deviation between the 10 series to be almost double that of the within series estimate, very similar 'to my findings in Table I. Bleeker (1960) seems to be right in pointing out that Rosengren overlooked the physiological fluctuations when he explained his findings solely as "incorrect judgment by the observer". Physiological variation must exist but how large?…”

In connection with a population study of the anterior chamber depth (ACD), measured optically with Haag Streit 900 instruments, a field study of the method was performed. The random error of measurement was estimated in two ways: a) on the basis of the triple readings of the measuring procedure: s.d. = 0.020 mm and b) by reexaminations after a few weeks in a random sample of 52 persons: 0.037 mm, i.e. a significantly larger value. Corresponding results for corneal thickness were obtained (0.007 and 0.013 mm).A highly significant side difference -with larger left eye values -was (0.019 mm), in 900 pairs of eyes. The correction values due to radius of corneal curvature were found to be negligible. Against a background of large interpersonal variations of ACD the methodological problems seem to be small. ACD is a precise anatomical measure with this method. L n ACD (mean difference: 0.020 mm) and in corneal thickness

“…39 The reason for this discrepancy with the previous studies on human subjects may be due to the measurement techniques used or the data collection protocols used in the different studies. In our present study, we took six measurements over 24 hours, as opposed to two measurements 12 hours apart 39 or serial measurements between 0900 and 1700 38 in the previous studies.…”

“…Assessing the case after the use of miotics may be misleading here; both the width of the angle and even the depth of the anterior chamber (Bleeker, 1960) may decrease as a consequence of their use. In any case, as surgeons who use one drainage procedure for all types of glaucoma usually incorporate iris surgery in their techniques, the "curable" part of the closed-angle element is incidentally taken care of.…”
