[Pigmentary dispersion: is iridectomy useful?].
Several clinical reasons induced Campbell to propose an iridotomy in cases of pigmentary dispersion: removing the inverse pupillary block, balancing pressures through the iris, and finally stopping the posterior erosion of the iris leading to pigmentary release. It is likely that certain failures in this method stem from an erroneous evaluation of the cases that could benefit from iridal perforation. Three conditions are required for this procedure to be successful: established ocular hypertension, an abnormally concave iris base, and absence of patent glaucoma.
