LHON Awareness Day - Mito Patients

LHON Awareness Day banner! Thursday 19 September

LHON stands for Leber’s Hereditary Optic Neuropathy. In LHON the optic nerve is particularly vulnerable to mitochondrial defects because of the high-energy requirements and the need to keep the retina transparent to light.

LHON has a prevalence of 1/25,000 to 1/50,000 and it is more frequent in males.

Every year we work to draw more attention to this condition. Help us shine a light on LHON.

This year LHON Awareness will be on Friday 19th September.
