Very common question. High intraocular pressure can often be a sign of glaucoma which can lead to different degrees of vision loss if not properly treated. Now on the bright side, there are also people with elevated pressure who don't have glaucoma. There are many factors including optic nerve anatomy, peripheral vision changes, anatomy of drainage angle, corneal thickness and retinal nerve fiber thickness that go into making the diagnosis of glaucoma. It sounds like you are borderline at worst so keep your follow up appointments and if needed in the future someday it might be that you actually have to start treatment for glaucoma but as long as you are under the care of a good ophthalmologist, you should have nothing to worry about. It might be that you never develop glaucoma, also. That would be great.

I am a 31 year old man with a similar condition - high myopia -11 with floaters and currently on medication for reducing eye pressure. I have been taking this from the past 3-4 years.
