How High Is Dangerous Eye Pressure
Glaucoma: Intraocular pressure, iop. Normal is between 10-21. This is an indicator of the relative pressure in the eye. Fluid is formed behind the lens and flows into channels in the front of the eye. Elevated pressure can indicate glaucoma, that can cause vision loss by damage to the optic nerve. It is typically painless. Low pressure can indicate the eye is very sick, from inflammation or scarring. Read moreSee 1 more doctor answer

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. Read more
The same way: Treatment of eye pressure high enough to cause problems is the same for teenagers as it is for adults. This would be a sequence of eyedrops, laser and operative surgery. Elevated pressure in teenagers is very uncommon so a good examination by an ophthalmologist should be undertaken to discover any other problems. Read more
Various: Eye pressure can be falsely elevated (machine error, operator error, corneal scar, etc.), elevated due to thick central corneal thickness, high due to recent eye surgery (i.e. Retained viscoelastic, etc.), etc. However we commonly refer to high eye pressure as having glaucoma, but it's not always true since there are ocular hypertensives with high pressure that never develop glaucoma.

Many things: Glaucoma is caused by high intraocular pressure. Some people can have high pressures (ocular hypertension) and not have developed glaucoma yet. Many things can increase intraocular pressure including impaired "drainage channels", neovascularization, inflammation, and impaired venous outflow. In order to determine the cause, a complete eye exam with an ophthalmologist would be required. Read more
Contact lens care: Poor contact lens hygiene can lead to eye irritation and infection but will not directly cause your eye pressure to go up. If the infection is severe enough, then the pressure could go up as a secondary effect, but this will not happen merely because of not taking proper care of your lenses. Read more
Had annual eye exam. Eye pressure showing high-24. I am 43. Need to go for further tests. How worried should I be?
Some may: Very few medications cause elevated eye pressure in and of themselves. Some eyes are shaped in such a way as to be at risk for increased pressure (narrow angles). Certain medications are able to cause narrow angles to become even more narrow, causing the pressure in the eye to elevate. If you are at risk for certain glaucomas, you should see a doctor before starting any new diet medication. Read moreSee 1 more doctor answer
No: Contacts can cause problems with the eye surface such as allergies to contact cleaning solutions, infections, poor oxygen supply to the cornea, but do not affect the intraocular structures. Eye pressure is determined by the rate at which the aqueous fluid is made within the eye and resorbed through a structure called the trabecular meshwork (also within the eye). Read more
See ophthalmologist: Opticians make and fit eyeglasses using a prescription from an optometrist or better yet, an ophthalmologist. Eye pressures vary but there is a normal range. If it is high enough to risk visual damage, we call that glaucoma. A high pressure needs immediate evaluation as good treatment is available. See an MD ophthalmologist to protect your eyesight if you have this problem, Read more
Rule out glaucoma: Eye pressure normally runs between 10 and 20mmhg (milimeters of mercury). If the pressure runs higher, eye doctors want to evaluate if there is an underlying cause for it, such as glaucoma. Other factors can cause the pressure to appear high, such as a thick cornea or excessive squeezing during the test. Have a full dilated eye examination soon. Read moreSee 2 more doctor answers
My eye pressure in left eye 25 and 27 in right eye. Field test abnormal. I have always had high pressure around 21-23. Your thoughts?
If your eye pressure is 20 what does that mean? He told me it was high but do I need to worry about anything? Would this cause migranes and headaches?
Usually not: Elevated intra-ocular pressure usually causes no symptoms on its own. The results oif long-standing elevation of intra-ocular pressure can be peripheral visual loss. Extreme elevation of intra-ocular pressure as in acute angle closure glaucoma often causes eye pain, nausea, vomiting and blurred vision. Read moreSee 1 more doctor answer
