The capsule of the lens has important physiologic and pathologic functions, and although much has been written concerning its structure, few modern expositions have appeared. The examination of that part of the lens capsule which is in front of the equator and commonly known as the anterior capsule is possible by direct inspection, by oblique illumination, with the ophthalmoscope, with the gonioscope and with the slit lamp. With the slit lamp, a trained worker sees the commonplace in a new light and examines the part with a broader conception of its possibilities. Pathologic study can be made only in a limited number of cases and then only after the removal of the eye, or an isolated portion of the capsule, or of the lens in its capsule.
A review of the anatomy of the capsule (fig. 1) shows that it consists of a thin, glass membrane, which exhibits a tendency
