EOD Primary Tumor

This input is used for staging

Notes

**Note 1:** If both eyes are involved, code the information for the most extensively involved eye in this field. **Note 2:** Pathological staging information from an enucleation always takes precedence over clinical staging, except in cases with neoadjuvant treatment where clinical disease is as extensive as or more extensive than disease at surgery.
