This is a 67 year old male who has elevated intraocular pressures in both eyes, the right greater than the left. At age 13 he had severe blunt trauma to the right eye and had a very slow recovery and then a gradual decline again during his childhood. He had been treated for elevated intraocular pressure for over 20 years at the time these videos were taken. The patient has extensive angle recession and has a secondary pigment dispersion syndrome in the right eye. While his axial eye lengths are symmetrical his anterior chamber depth on the right side is deeper than the left (3.52 mm OD and 2.30 mm OS). This patient has been published: McKinney, J. K. and W. L. Alward (1997). "Unilateral pigment dispersion and glaucoma caused by angle recession." Arch Ophthalmol 115(11): 1478-9. Asymmetric pigmentary glaucoma caused by unilateral angle recession: Ritch, R. and W. L. Alward (1993). "Asymmetric pigmentary glaucoma caused by unilateral angle recession." Am J Ophthalmol 116(6): 765-6. NOTE: This clip is presented both under angle recession and under pigmentary.
