Subluxated cataract

The patient is looking down. With the slit-lamp, the superior equator of the lens is at the margin of the pupil at 12 o'clock. The subluxated (partially dislocated) lens is heading towards a luxation (dislocation) into the floor of the vitreous chamber. In rural India, a couching mark had to be sought whenever a dislocated lens was present. In this patient the dislocation was spontaneous. That is a potentiality whenever a cataract is neglected and allowed to go beyond the mature stage.
