Detachment of intact posterior lens capsule: secondary to contusion in penetrating ocular trauma.

Severe contusion of the lens in a penetrating scleral injury of the eye of a young patient resulted in separation and bleb-like detachment of the posterior lens capsule with subcapsular accumulation of a fibrin-containing exudate. This separation of the posterior lens capsule resulting from increase of permeability with subcapsular fluid accumulation is believed to represent a possible basic mechanism of posterior lens involvement without capsule rupture secondary to ocular trauma.
