On the side away from which the lens is drawn the iris falls back and the anterior chamber is deepened. The with- drawal of support from behind the iris in this position causes it to be tremulous on movements of the eye, a condition termed iridodonesis. The vitreous humour at the site of the rupture in the suspensory ligament may protrude forward to the back of the iris, and even pass through the pupil into the anterior chamber (Fig. 190).. Fig, 191.—Section through the anterior part of an eye in which the lens has become dislocated into the anterior chamber as the result of blow. Secondary glaucoma ensued. Occasionally, when the lens is much drawn over to one side, and the iris much pushed back on the other, its pupil- lary margin will there slip around the edge of the lens to its posterior surface, a partial dislocation of the lens through the pupil being the result. In some cases the backward displacement of the iris round the side of the lens is so exten- sive that part of it clinically disappears from view; this is called retroflexion of the iris. When, as the result of the pressure backward of the iris against the suspensory ligament, that structure becomes torn through in its entire circumference, the lens may be dislocated forward into the anterior chamber (Fig. 191) or.
