Question
What are the dangers of pediatric optic nerve glioma?
Answer
Increased intracranial pressure or direct compression of the dura mater, blood vessels, and nerves due to the tumor. This is seen in the vast majority of patients and is an early symptom that worsens as the tumor expands. 2) Dry heaves: Often due to increased intracranial pressure affecting the vomiting center in the medulla oblongata and the vagus nerve being strained. Severe headache can lead to second-degree neuron-induced dry heaves, often presenting as vomiting. Children with posterior fossa tumors may experience dry heaves earlier and more frequently, which can be mistaken for gastrointestinal disorders. Visual impairments: Including changes in vision, field of view, and fundus of the eye. Due to increased intracranial pressure or direct compression of the optic nerve by the tumor, over time this can lead to optic nerve atrophy and interfere with vision.
