Background: The aim of this study was to report on epithelial posttraumatic iris cyst that was successfully treated with needle aspiration and surgical excision with surrounding iris tissue.
Case Report: A 30-year-old women was treated for a large fluid-filled cyst in the anterior chamber of the left eye; 25 years before, she had an open globe injury. She observed deterioration of her visual acuity 1 year before her visit to our clinic. During ophthalmological examination, an iris cyst was diagnosed. As a result, she had Nd: YAG laser puncture of the cyst in the left eye, performed 5 months before she came to our clinic. After a short time of decompression, the cyst rapidly grew in size (2/3 of the anterior chamber), and her visual acuity was getting worse due to an aggressive growth of the iris cyst. Visual acuity was 0.06. Needle aspiration with surgical excision of the cyst with surrounding iris tissue was performed. Histopathologic examination confirmed an epithelial cyst. At the 1-year follow-up, there was no evidence of recurrence of the iris cyst, and BCVA was 0.2.
Conclusions: This case report provides evidence that needle aspiration with surgical excision of iris cyst seems to be an effective treatment method of this complication.
