Pigment Glaucoma (Burned-out)

This 75 year-old woman was found to have cup-to-disc asymmetry. Her intraocular pressures were normal at 13 mmHg OD and 11 mmHg OS. She was found to have evidence of pigment dispersion syndrome and it was presumed that the optic nerve head asymmetry was from pigmentary glaucoma when she was younger.
