OPTIC ATROPHY

NEURO-OPHTHALMOLOGY: OPTIC ATROPHY

AetiologicaL FACTORS in Children
- Hydrocephalus
- Hereditary (dominant, recessive, or x-linked)
- Space occupying lesions (intracranial, orbital)
- Heavy metal poisoning (lead, arsenic)
- Secondary to papilloedema
- Cerebral DegenerationsClinical Findings

FINDINGS
- Diminished vision
- Pupil reaction to light reduced
- Marcus Gunn Pupil – (consensual reaction greater than direct)
- Pallor of optic disc and reduced vessels on disc.
- Visual field changes

Investigations
- Visual Evoked Potential - (of particular value in children too young to measure vision or visual fields.)
MRI Scan is necessary

Note: Optic Atrophy requires a full neurological investigation
