Uveal metastasis is the most common intraocular malignancy. Lung cancer is one of the most common malignancies that metastasize to uvea. Iris involvement is rarely reported. Here we report a case of iris metastasis from pulmonary adenocarcinoma that was treated with photodynamic therapy (PDT). A 65-year-old Chinese man was referred to our hospital for iris white neoplasm and blurred vision for 2 weeks in his right eye. His accepted pulmonary lobectomy, radiotherapy and chemotherapy for pulmonary adenocarcinoma 1year ago and liver metastases were found 2 months earlier. At presentation, anterior segment examination of the right eye showed a hypopigmented, vascularized papillary 3.8 *3.19mm neoplasm located on the temporal iris expanding to 9-clock anterior chamber angle. The patient refused to accept MRI, biopsy and treatment. One week later the tumor grew up to 5.5*7.4mm with diffuse mixed conjunctiva congestion and elevated IOP. A modified PDT was applied. Intravenous verteporfin (3mg/m2) was infused with a 1min bolus. PDT with 3 partly overlapped 5mm laser spots, 689nm (50J/cm2) and 166s were performed 4 minuets later without contact lens. The neo-genesis vessels were occluded with small patch bleeding on the edema tumor that was separated from the anterior chamber angle in the 3days follow-up. PDT may be a safe, noninvasive and psychologically well-accepted treatment for iris metastasis.
