Pigment dispersion syndrome (PDS) is an eye disorder that can lead to a form of glaucoma known as pigmentary glaucoma. It takes place when pigment cells slough off from the back of the iris and float around in the aqueous humor .
Krukenberg's spindle is the name given to the pattern formed on the inner surface of the cornea by pigmented iris cells that are shed during the mechanical rubbing of posterior pigment layer of the iris with the zonules that are deposited as a result of the currents of the aqueous humor.
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]
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 dispersing factor (pdf) is a gene that encodes the protein PDF, which is part of a large family of neuropeptides. [1] Its hormonal product, pigment dispersing hormone ( PDH ), was named for the diurnal pigment movement effect it has in crustacean retinal cells upon its initial discovery in the central nervous system of arthropods .

The discolored skin is caused by excessive deposits of melanin (normal skin pigment). Most newborns with IP will develop discolored skin within the first two weeks. The pigmentation involves the trunk and extremities, is slate-grey, blue or brown, and is distributed in irregular marbled or wavy lines. The discoloration sometimes fades with age.
There are a wide range of depigmenting treatments used for hyperpigmentation conditions, and responses to most are variable. [11]Most often treatment of hyperpigmentation caused by melanin overproduction (such as melasma, acne scarring, liver spots) includes the use of topical depigmenting agents, which vary in their efficacy and safety, as well as in prescription rules.
