Optic nerve atrophy in adrenoleukodystrophy detectable by optic coherence tomography.
The adrenoleukodystrophies (ALDs) are a group of metabolic disorders characterised by the accumulation of very long-chain fatty acids in all tissues. The two most frequent ALD phenotypes are adult-onset adrenomyeloneuropathy (AMN) and childhood cerebral ALD. Visual system involvement in the adult phenotype is well described as impairment of visual function and optic disc pallor on clinical examination accompanied by demyelination of the optic nerves seen on MRI. Thinning of the retinal nerve fiber layer and ganglion cell death has been described in a neonatal form of ALD. Our patient provides evidence, through ocular coherence tomography scanning of the retina, that such degenerative changes also underlie the visual dysfunction seen in the AMN phenotype.
