Abstract:
Leber hereditary optic neuropathy (LHON) is a rare mitochondrial genetic disorder characterized by painless acute or subacute vision loss that develops during adolescence. Clinicians should know how to identify potential LHON and when to refer patients to a neuro-ophthalmologist for diagnosis and treatment. This case highlights the value of a thorough family history in ED patients.
