Could you tell me all they know about high eye pressure?

High eye pressures: Can cause glaucoma. This is a condition which damages the optic nerves. Early on, this causes basically no symptoms. It initially affects small focal areas of the peripheral vision. If it gets worse, then it can start affecting the more central part of your vision. If your eye pressures are high, then you should be followed regularly by your ophthalmologist and use drops to lower it if needed.
