### Patient: Doctor, I have been diagnosed with Ependymoma. What medical tests do I need to undergo?
### Doctor: You need to undergo an ophthalmic examination and evaluation to check your eyes because the tumor may have spread to your eyes. You also need other therapeutic procedures on eyelids, conjunctiva, and cornea. For diagnosis and treatment, an ophthalmologic and otologic examination is necessary. If required, there may be a need for lens and cataract procedures. In addition to this, a biopsy may be required to confirm the diagnosis. If there is a corneal disease, you may need a corneal transplant. Lastly, there may be a need for procedures on the spleen, known as a splenectomy, if the tumor has spread to the spleen.
