Ciliary body metastasis from renal cell carcinoma successfully treated with intravitreal bevacizumab

PURPOSE: To report an innovative new treatment option for ciliary body tumor metastasis from renal cell carcinoma treated with intravitreal bevacizumab. OBSERVATIONS: A 70-year-old Caucasian man presented with a ciliary body tumor as a result from metastasis from renal cell carcinoma. It was preferable to treat the ciliary body tumor in the least invasive manner possible based on the patient's health, systemic metastasis, and the invasiveness of local resection. The tumor was treated with intravitreal bevacizumab for attempted tumor regression. Complete tumor resolution occurred following three injections. CONCLUSIONS AND IMPORTANCE: There is no consensus on treatment for ciliary body metastases from renal cell carcinoma. Based on the successful result of our patient, intravitreal bevacizumab could be an acceptable treatment option for this type of intraocular tumor. It affords a relatively non-invasive method of tumor regression without undergoing major intraocular surgery.
