Exercise has been shown to contribute to spikes in pressure as well. When the pressure is great enough to cause damage to the optic nerve , this is called pigmentary glaucoma. [ 1 ] As with all types of glaucoma, when damage happens to the optic nerve fibers, the vision loss that occurs is irreversible and painless.
Nd:YAG laser peripheral iridotomy (LPI) may be used in patients susceptible to or affected by angle closure glaucoma or pigment dispersion syndrome. During laser iridotomy, laser energy is used to make a small, full-thickness opening in the iris to equalize the pressure between the front and back of the iris, thus correcting any abnormal ...

Those with moderate amounts of myopia are more likely to have pigment dispersion syndrome or pigmentary glaucoma. [84] High myopia usually describes myopia of −6.00 or more. [65] [85] People with high myopia are more likely to have retinal detachments [86] and primary open angle glaucoma. [87]
Pigment dispersion syndrome – a condition characterized by loss of pigmentation from the posterior iris surface which is disseminated intraocularly and deposited on various intraocular structures, including the anterior surface of the iris. [medical citation needed]
