You really can't get more of a fastball down the middle for me here
I am an ophthalmologist specializing in retinal surgery for diabetics....so I may have a few things that will help you.
Uvietis: A catch all term for inflammation of any of 3 areas of the eye. Getting this once in your life is no big deal, but I always become very concerned if a patient experiences this over and over....the reason is that there is a VERY high correlation with certain autoimmune disorders, mostly RA, JRA, and lupus....I am not a believer that diet alone will reverse these once they onset, but it often DOES prevent onset and is very helpful for reducing symptoms, sometimes markedly. If you are getting a uvieitis, iritis (inflammation of the iris), or especially posterior uvietis on a regular basis, there is almost always a systemic underlying issue we need to explore. Going blind is extremely rare from it though, and is usually caused by the posterior form (itself very rare) that is very hard to detect.
Glaucoma: Sorry, but I do not believe the most common form of this has anything to do with diet. POAG, or Primary Open Angle Glaucoma, is by far the most common, and appears to be a mixture of anatomy, genetics, and neurology. It is caused by idiopathic, prolonged high eye pressure, which has no correlation to blood pressure. With this said, it is also the most treatable form, usually with eye drops or relatively non-invasive surgery.
Other forms of glaucoma are more inflammatory, such as pigmentary glaucoma. These also tend to run in families, but I believe nutrition likely has a role.
Anything specifically you are experiencing?
"They now look to a single and splendid government of an aristocracy, founded on banking institutions, and moneyed incorporations under the guise and cloak of their favored branches of manufactures, commerce and navigation, riding and ruling over the plundered ploughman and beggared yeomanry." - Thomas Jefferson, 1826
