Purpose: To present the prevalence of iridociliary cysts on patients submitted to UBM examination.Methods: We analyzed retrospectively the UBM images of 1157 patients in the period from September 1995 to June 2004. The inclusion criteria was the presence of UBM images from the four quadrants (superior, inferior, nasal and temporal). We assessed the cysts in relation to its number; localization and morphology in each quadrant. We took the measurements of the largest diameter, wall thickness and area of the cysts besides the angle recession area (ARA). The software UBM Pro 2000 was used. Results: The prevalence of the cysts was of 4.9%. Their prevalence was highest on women and on the right eye. They were more prevalent on the inferior and temporal quadrants. The cysts with largest diameter and area were located on the superior and temporal quadrants. No difference was found in relation to cysts’ wall thickness in all quadrants. Conclusions: Iridociliary cysts are more prevalent on the inferior and temporal quadrants. The location of the largest cysts are preferentially the superior and temporal quadrants. The cysts’ wall thickness is practically the same in all quadrants.
