[Symptoms of glioma of the optic nerve
It manifests itself in the first decade of life with a slow decrease in vision, then exophthalmos joins, although sometimes the sequence of events can be reversed.
The following signs of glioma of the optic nerve are distinguished:
- Dysfunction of the optic nerve with impaired vision is proportional to the degree of exophthalmos.
- The disc of the optic nerve is swollen initially, later becomes atrophic.
- Occasionally visible are opticociliary vascular shunts.
- It can spread intracranially towards the chiasma and the hypothalamus.

Treatment of glioma of the optic nerve
Treatment of glioma of the optic nerve depends on the spread of the tumor in the rear direction.
- Observation is indicated in the absence of signs of growth, good vision and lack of cosmetic defects.
- Surgical removal with preservation of the eye is indicated in case of tumor growth, especially with low vision and pronounced exophthalmos.
- Irradiation in combination with chemotherapy is indicated for intracranial dissemination, in which removal is impossible.
The forecast is ambiguous. Some tumors are dormant and grow very slowly, while others are progressing intracranially and threatening life.
