Anyone heard of this? Foal going blind!!

Gggrrrr. Can't get it to work. In summary...

Foal born. All fine and about 5 months old now. Suddenly goes inexplicably blind about 6 weeks ago. All eye scans ok and optic nerve ok too. Anyone seen anything like this before?
 
Has had thousands of shares on FB. Hope they do find a cause. There is no optic nerve damage, no ulceration, or any visual damage.

Have heard of similar cases in the USA, only a few, but all were Lepto infected.
