I ended up using the prescribed drops----until CRPS intervened and I was too ill to deal with getting another prescription for the drops.

When I visited the eye doctor yesterday I was caffeine free and my eye pressure was normal. She wanted to attribute the low reading to the drops, but I had not used them for over a year. This time she accepted that caffeine caused the anomalous reading, no glaucoma.

Research on the net confirms that caffeine can cause high ocular pressure. Avoid caffeine before having an ocular pressure test.
