Optic Nerve Glioma | Symptoms & Causes

What are the symptoms of optic nerve gliomas?

Brain tumors can cause a variety of symptoms in children based on their age and the location of the tumor. Keep in mind that the symptoms of an optic nerve glioma may resemble other more common conditions or medical problems, such as needing glasses to correct poor vision. It is important to consult your child's physician for a diagnosisThe most common optic nerve glioma symptoms are:

  • vision problems
  • proptosis (eyeball protrusion), which occurs when the tumor is pushing the eye outward from the socket
  • hormonal problems including abnormal growth, weight gain or loss

What causes optic nerve gliomas?

In most cases, the cause of optic nerve gliomas is not known. It’s important to understand that these and other brain tumors most often occur with no known cause. There’s nothing that could have been done or avoided that would have prevented the tumor from developing.

Optic nerve gliomas are more common in kids who have a genetic condition called neurofibromatosis 1 (NF1). NF1 can cause tumors to form, and optic nerve gliomas occur in about 15 percent of children with this disease. In these cases, about two-thirds of the time, the tumor stops growing and disappears forever on its own without treatment.
