Laser Iridotomy Ineffective in Pigment Dispersion Syndrome After All
March 25, 2011
Ophthalmology: For many years, the conventional wisdom- which made a lot of sense- was that pigment dispersion syndrome is due to posterior bowing of the iris against the zonules, and therefore an iridotomy would halt further pigment dispersion by equalizing the pressure gradient and making the iris more flat.
