ABC57 Health Alert: Sudden blindness, dealing with this rare hereditary disease

SOUTH BEND, Ind. -- Imagine your vision starts to blur, partially at first, maybe even in just one eye, but over time it starts to get worse. And when you talk to your doctor about it, you may discover you're one of just 100 people who get diagnosed with Leber Hereditary Optic Neuropathy, or LHON, each year.

That's what happened to Kris Garvey Graves.

LHON is a rare hereditary disease which only around 4,000 people in the US have been affected by.

Graves stopped by to discuss how she's now learning to live life with the sudden loss of vision.

The disease can cause blindness in six to 12 months and according to the Cleveland Clinic, often affects people in their childhood up to young adulthood, but, if someone carries the mutation, diagnoses can happen at any time.

You can learn more about LHON online here or here.

Graves also has a GoFundMe up to help with the costs of living with the disease.
