This is a controversial issue right now. Half of the studies say yes, the other half no. There is no evidence in the literature to connect stress with glaucoma. However, the subject has been explored minimally. Because acute and chronic stress affect levels of steroids and other hormones, it is quite possible that some connection will eventually be shown.
More research is needed here.
Not that we're aware of. Although fluid intake is good, glaucoma patients should not drink as much as one quart of water within 15-30 minutes. While in some individuals a drink or two has been known to lower IOP, this positive effect lasts only a brief time and provides a misconception that IOP is being controlled, when in fact it is not. While patients should not look at alcohol intake as a treatment, a few drinks should not be harmful to a glaucoma patient. For years it was thought that caffeine had no effect on IOP, except in rare instances.
