Optic pathway glioma (code 2086)
Optic pathway glioma is a benign tumor that develops along the optic nerve (chiasm, tract, and radiations). It is characterized by impaired or lost vision and may be accompanied by diencephalic manifestations, such as reduced growth and altered sleep patterns. Optic pathway glioma is often associated with neurofibromatosis type 1 (NF1).
