Ciliary Body Metastasis Treated with Radiotherapy Alone in a Case of Lung Adenocarcinoma: A Case Report

Aim: To describe local treatment of ciliary body metastasis in a case of metastatic adenocarcinoma of the lung using radiotherapy only.

Presentation of Case: A 62-year-old lady, diagnosed case of metastatic non-small cell lung cancer, presented to us with blurred vision, diminution of near and distance vision and floaters in left eye in October 2023. She was further evaluated and treated with radiotherapy.

Discussion: Ciliary body metastasis in a non-small cell lung cancer is extremely rare. Intraocular metastasis by any cancer most commonly involves choroid followed by iris and ciliary body. Symptoms include blurred vision, pain, floaters, visual field defects, red eyes, double vision and blindness. Management includes therapies for systemic control and radiotherapy for local control.

Conclusion: Lung cancer patients with eye symptoms must be evaluated for the presence of ocular metastasis. External beam radiotherapy is deemed as a safe local therapy option in cases where other modalities have failed.
