OBJECTIVE: To study the anterior chamber in pigmentary glaucoma by anterior ultrasound biomicroscopy (UBM), and to determine the effect of YAG-laser iridotomy on intraocular pressure (IOP) and iris morphology in pigmentary glaucoma. MATERIAL AND METHODS: Seven patients (14 eyes) with a diagnosis of pigmentary glaucoma were studied. YAG-laser iridotomy was performed on all patients with demonstrable iris concavity by UBM, performing UBM one week post-iridotomy and control of the IOP at one week, six months, and one year following treatment. RESULTS: The existence of iris concavity was demonstrated in six of the seven patients (12 of 14 eyes), by performing YAG-laser iridotomy in all cases. Remission of the iris concavity was observed in five of the six patients (ten of 12 eyes) and good control of IOP was achieved without additional topical treatment in three (six eyes). At one year, the number of drugs needed for IOP control decreases (p < 0.005, Wilcoxon test, correction for small samples). CONCLUSIONS: In this sample, YAG-laser iridotomy rectified the iris concavity present in pigmentary glaucoma, reducing IOP and the number of drugs needed for its control. LA: Spanish
