The changes of the lens location during medical control of intraocular pressure. a. The crystalline lens was totally dislocated into the anterior chamber in the left eye with corneal edema due to pupillary-block glaucoma; the intraocular pressure was 45 mmHg. b. The same lens dislocated in the right eye with normal intraocular pressure of 16 mmHg; the iris atrophy was clearly observed around the pupil. c. With control of the pressure, the corneal edema disappeared in the left eye and the lens was still in the anterior chamber. Marginal atrophy around the pupil was apparent. d. After the patient stood up from lying on his back, the spontaneous backwards movement of lens into the vitreous cavity in the left eye was detected. The white arrow indicated the dislocated lens in the inferior vitreous cavity
