Because there are different types of brain tumors that can form behind the eyes, there can be different causes for them that can include cancer and genetic disorders or mutations. For example, an optic nerve glioma is a rare form of cancer that tends to affect children and is linked to different forms of the genetic neurological disorder called neurofibromatosis, notes Healthline. Treatment options for a brain tumor behind the eyes include surgery, radiation and chemotherapy.
Different types of brain tumors can affect the area behind the eyes, including optic nerve glioma, pineal tumors and rhabdoid tumors. Optic nerve gliomas can develop either on or near the optic nerve that is located between the brain and eye regions. The main symptoms of this condition are gradual vision loss, double vision and headaches. If this tumor is small it may be completely excised. A larger tumor may require radiation treatment to reduce its size before excision. Chemotherapy may also be part of the treatment plan.
Rhabdoid tumors affect different areas of the body, including the kidneys, central nervous system and other ares of the brain. When the condition leads to an orbital tumor, a protruding eye can occur, states the National Brain Tumor Society. The cause of this condition is a genetic mutation, notes the Children's Hospital of Philadelphia. The treatment options for either a pineal or rhabdoid tumor are also surgery, radiation and chemotherapy.
