The most important thing is what type of "doctor' you are seeing. As a diabetic and potential glaucoma patient you should be under the care of an EYE MD also called ophthalmologist. You should not be under the care of a non-physician optometrist ( OD degree) so 1. be sure you are under the care of EYE MD. If not get in to see one immediately. If you are under the care of an Eye MD I would get a second opinion from an Eye MD that specializes in glaucoma. You were on steroid eye drops for a long time. We normally don't like to do that as about 8% of people develop increased intra ocular pressure (IOP) also known as steroid glaucoma. FML is a steroid and normally we would not put anyone one on chronic FLM therapy for allergic conjunctivitis or dry eye. I don't know what CMC is abbreviation for so please tell me, perhaps it also is a steroid. Your 'doctor' is thinking along the same lines as steroid OHT (ocular hypertension) means the pressure is up because of chronic steroid use. The tests that were suggested are to see if you have permanent damage (side vision test, and measurement of nerve fiber layer by OCT). re-read this several times. Get with an EYE MD, if you are get a second opinion. I am making an assumption you DO NOT wear contacts. If you do they should be discontinued. If you have heavy duty dry eyes (unusual in young male) and not get relief with artificial tears 2-4 times/day then you might be a candidate for restasis or cequa which will not raise pressure in your eyes.
