Thank you for the additional information and test results.
It sure does appear from that one visual field test that you have glaucomatous visual field loss in your right eye. Of course, without knowing your optic nerve morphology and eye pressure history it is impossible to rule out other causes....
I would say that you should consult with a glaucoma specialist rather then just be labeled a "glaucoma suspect" and sit around and watch things......vision lost to glaucoma can never, ever, be restored.
It is hard to tell if all your symptoms are related but, from what you have posted, I do not believe that there is one underlying cause...
Does this make sense to you?
It's safe for you to press the positive feedback button now if you so desire. And, never fear, even after you press that button I'll still be right here to continue helping you, but, as I do work for tips, I want to make sure you are happy before rating me.

Concerning your nodule I would probably like to see it checked in 6 to 9 months as we really do not have any data on how it has been changing over time. In that light, it seems prudent to get a look at it again a bit sooner.
