Pigment-dispersion syndrome – http://id.who.int/icd/entity/52858449

Pigment dispersion syndrome (PDS) is an ocular pigmentation disease due to the deposition of pigment granules throughout the anterior segment of the eye and characterised by the presence of mid-peripheral, slit-like, radial iris transillumination (TI) defects, a vertical band of corneal pigmentation (Krukenberg (K)-spindle), and dense pigmentation of the trabecular meshwork. PDS is also associated with an increased risk of pigmentary glaucoma.
