Glaucoma risk: Pigmentary dispersion is a syndrome where pigment is liberated from the back to the iris due to chaffing and is released into the aqueous humor. The pigment gradually obstructs the drainage apparatus of the eye and in about 30% of the time, may cause enough elevation in the eye pressure to cause glaucoma (pigmentary glaucoma). Its more common in younger myopic males. Treatment is available.

Provided original answer
The Krukenberg spindle is a vertically shaped endothelial pigment deposition on the inside surface of the cornea. It represents a significant clinical sign of pigment dispersion syndrome, along with mid-iris transillumination defects, heavy gonioscopic angle pigmentation, and pigment on the equator of the lens where the zonular fibers attach.

What causes pigment dispersion syndrome?

Lens fibers rub iris: When the supporting lens fibers (zonules) of the lens are anteriorly placed on the lens, they can rub against the back of the iris leading to scraping off pigment which then circulates through the front of the eye. Most this is an interesting anatomical happening but in some cases the pigment clogs the eye drains causing glaucoma.
