pigment dispersion syndrome


Also found in: Acronyms, Wikipedia.

pigment dispersion syndrome

increased resistance to flow of aqueous humor through the pupil from the anterior chamber to the posterior chamber, leading to posterior bowing of the peripheral iris against the zonules; a possible mechanism for pigmentary glaucoma.
