Overview
Symptoms of optic nerve glioma include proptosis, unilateral or bilateral visual impairment, involuntary eyeball movement, squinting, obstructive hydrocephalus and diencephalic syndrome.
History
Common Symptoms
Decreased vision (63%) is usually evident and can be documented with visual field examination if the child is old enough. Eventually mass effects will also occur, with proptosis and even intracranial sequelae including symptoms of raised intracranial pressure, focal neurological deficits and hydrocephalus from distortion of the midbrain. Involvement of the hypothalamus may result in polyuria or polydipsia.[1]
The symptoms of optic pathway gliomas usually develop over a period of months to years and usually depend upon the location of the tumor.
- Proptosis- It is the presenting symptom.
- Impaired vision- In patients with chiasmal lesions, it is the presenting symptom. Unilateral or bilateral visual impairment that starts as the loss of peripheral vision and eventually leads to blindness.
- Obstructive hydrocephalus may also be noted as presenting symptom.
- Other less frequent symptoms are:
- Involuntary eye ball movement
- Squinting
- Hypothalamic gliomas may present with symptoms of the diencephalic syndrome, which include:
- Daytime sleepiness
- Decreased memory and brain function
- Delayed growth
- Loss of appetite and loss of weight
- Precocious puberty- Due to involvement of hypothalamic-pituitary-gonadal axis precocious puberty may occur in 39 % of children with chiasmal optic nerve gliomas and NF-1.[2] In 10 to 20 percent of patients with optic pathway gliomas endocrinopathies due to hypothalamic extension are present.
