What (who) is purpuric pigmentary angiodermatitis - definition

EYE DISEASE CHARACTERIZED BY SLIT-LIKE DEPIGMENTED AREAS OF THE IRIS WITH UP TO 50% OF PATIENTS GOING ON TO DEVELOP GLUACOMA
Pigment Dispersion Syndrome; Pigmentary glaucoma; Pigment-dispersion syndrome; Pigmentary dispersion syndrome

Pigmented purpuric dermatosis         
HUMAN DISEASE
Progressive pigmentary dermatosis; Progressive pigmenting purpura; Purpura pigmentosa chronica; Majocchi-Schamberg disease; Pigmentary purpuric eruptions
Pigmented purpuric dermatosis refers to one of the three major classes of skin conditions characterized by purpuric skin eruptions.
X-linked reticulate pigmentary disorder         
RARE X-LINKED GENETIC CONDITION
Partington amyloidosis; Partington cutaneous amyloidosis; Reticulate pigmentary disorder; Familial cutaneous amyloidosis; Partington syndrome type II; X-linked reticulate pigmentary disorder with systemic manifestations
X-linked reticulate pigmentary disorder is a rare X-linked genetic condition in which males manifest multiple systemic symptoms and a reticulated mottled brown pigmentation of the skin, which, on biopsy, demonstrated dermal deposits of amyloid. Females usually only have linear streaks of hyperpigmentation.

Pigment dispersion syndrome

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. Over time, these pigment cells can accumulate in the anterior chamber in such a way that they begin to clog the trabecular meshwork (the major site of aqueous humour drainage), which can in turn prevent the aqueous humour from draining and therefore increases the pressure inside the eye. A common finding in PDS are central, vertical corneal endothelial pigment deposits, known as Krukenberg spindle. With PDS, the intraocular pressure tends to spike at times and then can return to normal. 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. As with all types of glaucoma, when damage happens to the optic nerve fibers, the vision loss that occurs is irreversible and painless.
