Overview
Common physical examination findings of optic nerve glioma include nystagmus, strabismus, proptosis, visual impairment, afferent pupillary defect, edema and/or pallor of optic disc, torticollis and deficits of cranial nerve II.
Physical Examination
Eyes
- Nystagmus may be present.[1][2]
- Strabismus may be present
- Visual impairment may be present
- Proptosis
- Afferent pupillary defect may be present
- Fundoscopic examination may show pallor and/or edema of the optic disc due to atrophy. Initially, optic nerve head is swollen but subsequently it becomes atrophic. Central retinal vein occlusion and optociliary collaterals may occasionally be seen.
- On slit-lamp examination iris hamartomas (Lisch nodules) may be identified in optic nerve glioma patients with associated NF-1.
Head
- Torticollis may be present[3]
Neurological
- Mental status may be altered if obstructive hydrocephalus is present.
- There are deficits in cranial nerves II- Involuntary eyeball movement and loss of peripheral vision in one or both eyes may be present.
Skin
- Lesions may be present:
