[Measurement of the anterior chamber depth by the micrometer eyepiece].
Measurement of the anterior chamber depth by the micrometer eyepiece of the slit lamp is simple and easy. Refractive errors of the eye are important; they may cause a difference of over 0.6 mm when the chamber depth is between 2.6-4.3 mm. The variations of the difference are revealed in a curve, and by using a precalculated table, the actual chamber depths can be found for the apparent measured depths. The effects of the radius curvature and the thickness of the cornea are also discussed.
