Puccioni describes a cases of bilateral luxation of the lens in a young peasant girl. The lens was dislocated upward and inward in one eye and upward and outward in the other. Since she was much disturbed by asthenopia both lenses were extracted by means of s small flap operation. There having been no trauma and the eyes being otherwise healthy, the author thought the condition to have been brought about by the patient's habit of carrying heavy objects on her head. The straining of the muscles of the neck might so increase the intraocular tension that a weak zonula would be ruptured.
