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

Abstract

. 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.

An Unusual Case Of Ruptured Post-Traumatic Iris Implantation Cyst With Co-Existent Anterior Chamber Cilia

“…8 Our case had a good surgical outcome, even after 6 months post surgery there were no complication or recurrence, probably as the cyst was removed completely. In our case, the cilia might have entered into the AC along with corneal, conjunctival or eyelid epidermis.…”

“…The time taken between trauma and appearance of the cyst may range from 6 months to 20 years. 8 In a review of cystic iris lesions in children, only 4 of 57 iris cysts were of secondary origin, of which two were post-traumatic epithelial ingrowth cysts. 9 Small iris cysts may remain asymptomatic and static in size.…”

“…As many studies have found, surgical intervention has better outcome and lower recurrence rate compared to laser therapy [2,4,5]. Other non-invasive technique include irrigation with 100% ethanol and subsequent excision of the epithelial implantation cysts.…”

“…Various treatments had been advocated including Nd: YAG laser puncture of cyst, cyst aspiration, surgical removal by cystectomy or total excision with iridocyclectomy and laser treatment with photocoagulation or cryotherapy [1,2,4,5]. As many studies have found, surgical intervention has better outcome and lower recurrence rate compared to laser therapy [2,4,5].…”

“…Traumatic iris cyst is generally difficult to manage and has poor visual outcome as a result of the extensive proliferation of epithelial cells with pre-and post-operative complications [1,2]. Potential iris cyst complication are corneal edema, corneal decompensation, iritis, hyphema, raised intraocular pressure, subluxation of the lens, cataract and band keratopathy [3].…”
