The minimum significant (p = 0.05 level) detectable change noted on measuring anterior chamber depth by a photographic method was found to be 7% either way from the mean. The minimum significant change for a peripheral chamber depth 5 mm from the optic axis was found to be 25% either way.
通过摄影方法测量前房深度时，在0.05显著水平上检测到的最小显著变化，发现无论朝哪个方向偏离均值均为7%。对于距视轴5毫米处的周边房深度，发现最小显著变化无论朝哪个方向均为25%。
