Post-traumatic inclusion cysts of the iris: a longterm prospective case series

Purpose: Post-traumatic cysts of the iris pose a diagnostic and therapeutic challenge for ophthalmic surgeons. This prospective case series highlights the clinical spectrum and longterm outcomes of different modes of treatment in these cases. Methods: Eleven cases of post-traumatic iris inclusion cysts, treated with Nd:YAG laser and/or surgical excision were evaluated prospectively over periods ranging from 6 months to 3 years. Ultrasound biomicroscopy features and postoperative outcomes in each were evaluated. Results: Laser iridotomy of the cyst offers a non-invasive method of therapy in these cases but has a high rate of recurrence. The outcomes in most cases were poor, with worse results and more complications encountered in younger age groups. Conclusions: Iris inclusion cysts have overall poor surgical outcomes as the result of the extensive proliferation of epithelial cells, which may explain why the condition takes a rapid course in younger patients and why severe complications are encountered postoperatively in this age group.
