Purpose:
To describe the ultrasound biomicroscopic (UBM) features and complications associated with iris cysts.
Design:
A retrospective case series.
Methods:
Thirteen patients with iris cysts were identified in a 10 year period study at a ophthalmologic reference Center in Mexico City. The variables included demographic data, ocular and medical history, clinical course, and complications. All patients were examined by UBM, and type, number, location, and acoustic characteristics of cysts were evaluated. Descriptive statistics were performed.
Results:
Thirteen patients were included (8 men and 5 women). The mean age was 44.5 ± 15.5 years (range 6-70 years). The origin most prevalent was neuroepithelial (92.3%), and 7.7% had stromal cysts. Regarding to location 76.9% were found in the periphery, and 69.2% between meridians II and VI. All cysts showed a moderate to high reflectivity in the wall. Complications were present in 38.5% of cases (15.4% partial angle closure, 15.4% secondary angle closure glaucoma and 7.7% dyscoria).
Conclusions:
Most cysts are derived from iris pigmented epithelium, with a benign course and a minor rate of complications. The UBM is an indispensable tool that allows us to plan more specific and conservative treatments, with less damage to ocular structures and, therefore, better visual prognosis.
