It is hard to give your an answer since i don't know your other information such as your pressure, your corneal thickness and the results of a Humphrey Visual Field etc. And Glaucoma is a multi-factorial, complex eye disease with specific characteristics. And high eye pressure is one of symptoms of Glaucoma. But not all people with Glaucoma have high eye pressure, some of them are with normal eye pressure.
No. High eye pressure alone does not always lead to glaucoma. But it is a risk factor that can lead to glaucoma. Once you find your eye pressure is higher than the normal, you should go to see a doctor to have a comprehensive eye exam so that the doctor can figure out the causes of high eye pressure and then he will take measures to keep the eye pressure under control. Once the high eye pressure is under control, it won't cause glaucoma. While if you let the high eye pressure untreated, it may lead to galucoma.
High intraocular pressure can make the retinal nerve be oppressed, which then slowly lead to vision loss, this is glaucoma. Having a good rest can make the intraocular return to normal, unfortunately, this is not likely. So if you do not have a treatment, your eyes will in a state of high intraocular pressure, and it will gradually become worse until blind. It is not acute glaucoma, this process may be very slow, perhaps it will take a few years to go to blind. In any case, you should have a treatment early.
Normal intraocular pressure should be within the range of 11~21mmHg. However, due to the different degrees of tolerance of each optic nerve on the intraocular pressure, some peopleâ€™s intraocular pressure is higher than the normal value, but it do not damage optic nerve and visual field, this is called ocular hypertension, but rather glaucoma. Some people may have glaucomatous, the optic nerve and visual field are damage, but their intraocular pressure is in the normal range, which called normal tension glaucoma. That is to say high intraocular pressure is not necessarily glaucoma, people who have glaucoma can also have a normal intraocular pressure.
