I have poor eyesight and the first doctor told me the pressure was normal. A second doctor told me the pressure was high and put me on eye drops. After a year he told me it was still high. A third doctor told me its normal and to stop the eye drop. I really don't understand. Is there a different way of reading eye pressure?

The causes for high pressures in the eye: 1. Glaucoma, 2. Ocular hypertension, 3 Extremes of normal. Depending on how high your pressure is: i.e just over normal 21 or very high >28 let's say on 2 consecutive readings with a few weeks in between, then it is considered abnormal and must go for further investigations such as OCT, Visual field and may be packymetry. However, it is important to look at the optic disc as well. If they are abnormal looking, we must monitor you more closely and if there is family history as well. Other than that, by delaying a few weeks to find out why you have high pressures, without any treatment will cause you no harm. It is very important to make the correct diagnosis, because if it is glaucoma, you must use the eyedrops for life. If you already have poor eyesight because of this then you must seek a formal opinion and try not to change doctors too often as it requires serial measurements. PS. you can still have glaucoma even if your pressure is low or normal!
