• Local Resection: For smaller tumors, a local resection may be performed to remove the tumor while preserving as much of the eye as possible.

2. Radiation Therapy

Radiation therapy is frequently used either as a primary treatment or as an adjunct to surgery. The types of radiation therapy include:

• Brachytherapy: This involves placing radioactive seeds directly in or near the tumor, allowing for targeted radiation while minimizing damage to surrounding healthy tissue.
• External Beam Radiation Therapy (EBRT): This method delivers high-energy rays from outside the body to target the tumor, often used when surgery is not feasible or as a follow-up to ensure all cancer cells are eradicated.

3. Chemotherapy

While systemic chemotherapy is not typically the first line of treatment for ciliary body tumors, it may be considered in specific cases, particularly for metastatic disease or when the tumor is not amenable to surgery. Chemotherapy regimens may include agents such as:

• Dacarbazine
• Temozolomide

4. Immunotherapy

Emerging treatments, including immunotherapy, are being explored for their effectiveness against ocular tumors. These therapies aim to enhance the body’s immune response to fight cancer cells. Agents such as checkpoint inhibitors may be considered in clinical trials or specific cases.

5. Follow-Up and Monitoring

Post-treatment follow-up is crucial for early detection of recurrence or metastasis. Regular ophthalmologic examinations, imaging studies, and monitoring of symptoms are essential components of ongoing care.

Conclusion

The treatment of malignant neoplasms of the ciliary body (ICD-10 code C69.40) requires a comprehensive approach that may include surgery, radiation therapy, chemotherapy, and emerging immunotherapies.
