So what other areas make dopamine? I've heard that the eyes make trace amounts but haven't heard of other areas. I'm personally curious to learn if dopamine loss from the eyes impacts at all on glaucoma. I'm at an increased risk of glaucoma because my intraocular fluid pressures were right at the high end of normal (19-21 milligrams [or micrograms, I can never remember which] of mercury) on pressure tests the last two years, plus I'm very nearsighted. If my pressure readings get into the mid-20's I'd have to take eyedrops every day to lower the pressures and prevent the onset of the disease.
