Other signs and symptoms may be present and vary from person to person. This condition is caused by mutations in the OPA1 gene. It is inherited in an autosomal recessive manner. Treatment depends on the specific signs and symptoms seen in the patient."

Extraocular features can include progressive sensorineural hearing impairment, cognitive impairment, peripheral neuropathy, myopathy, ragged-red muscle fibers, and exercise-induced lactic acidemia, while additional ocular features can include progressive visual loss, central scotoma, and color vision abnormalities."
