Biomicroscopic examination revealed that the anterior chambers were very shallow bilaterally (Fig. 1).
(a) Scheimpflug screening of the patient's right eye during the first examination revealed anterior chamber shallowness, lens thickening, and anterior transposition of the iris-lens diaphragm. The anterior chamber depth is 1.97 mm and the lens thickness is 4.74 mm. (b) The patient's right eye as it appeared on the fifth day of discontinuation of the drug. The image shows a deepening of the anterior chamber and transposition of the iris-lens diaphragm to the usual position. The anterior chamber depth is 3.42 mm and the lens thickness is 4.27 mm.

A Scheimpflug image showed anterior chamber shallowness, lens thickening, and anterior transposition of the iris-lens diaphragm (Fig. 2a). Her uncorrected visual acuity was 20/20 in both eyes and the anterior chamber depth was normal (Fig. 2b).
