my approach to glaucoma: ammonia and neurodegenerative disease

My newest find.
We know from TCM about the liver - eye connection. Here is how one of these links works.
I have finally managed to check ammonia level (apart from other liver function tests).
A big hit. A big elevation (surprise, because I do not have any classic symptoms of ammonia overload).
High ammonia = subclinical hepatic encephalopathy = increased intercranial pressure and many other things commonly associated with glaucoma.
There is a plethora of research about the liver's impact in neurodegenerative diseases, surprisingly none about the liver's involvement in the pathogenesis of glaucoma.
