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 more
Needs evaluation: See an ophthalmologist for evaluation.Get a more detailed 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. ...Read more
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?
Depends on cornea: Eye pressure depends on corneal thickness: if thick, eye pressure reads as "greater than normal"; if thin, pressure is usually higher than measured. More info eyedoc2020@blogspot. Com ...Read more
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 more
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 more
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?
Probably fine: A pressure of 20 is within the normal range. You need to know your corneal thickness (pachymetry). The thicker, the better At your age eye pressure problems are rare. Eye pressure does not cause migraines or other headaches. ...Read more
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 more
Cant: That's the problem. I rare cases, if the pressure gets very high, it will hurt. But that's not typical. So you need to get the pressure checked on a periodic basis. ...Read more
Few: Unfortunately most cases of elevated eye pressure are from a gradual increase in the pressure which cannot be felt. An ophthalmologist can measure this. A far less common elevation, acute glaucoma, cause pain and vision loss quickly. If untreated, the major symptoms is vision loss but this takes a while in the usual case. Have your eyes checked regularly by your ophthalmologist. ...Read more
Usually cannot: Like blood pressure, it is difficult to feel any change unless it is at the extremes. Extreme high eye pressure is an emergency and results in loss of vision, pain, and even nausea. Having it measured with your doctor is the best way to catch the problem early and have it monitored. ...Read more
None, really.: High eye pressure (iop) is not caused by foods. Certain consumables lower iop like alcohol, caffeine, pot, and diuretics. Oral Prednisone or steroids are a possible cause of increased iop. Nothing quite substitutes for a healthy diet high in anti-oxidants, green leafy vegetables, etc. These are all around good, but no food needs to be avoided for high eye pressure. ...Read more
Depends on what's causing the high I pressure: If you have glaucoma, and have already been worked up by your eye doctor, then the eyedrops that are used are determined based on your other medical conditions present. If not, you have to be worked up first completely by the eye doctor to determine if you even have glaucoma. If you have narrow angles causing this, then eye drops won't be enough! You may also need laser iridotomy done to reduce pressures emergently. ...Read more
I was diag with ambylopia, nystagmus, high eye pressure and astigmatism. Is it normal to have this many eye conditions without an underlying cause?
Not rare: Astigmatism is a developmental ovalness of the eye and occurs to some degree in over 60% of humans. Amblyopia and nystagmus usually develop at birth or at young age. High blood pressure can occur at any age but is more common in those older than you. These are largely independent and not due to an underlying common cause. ...Read more
Your eye doctor: Will look to see if this high eye pressure can be monitored or needs treatment. The doc can perform tests to see if your eye pressure is causing any optic nerve damage. If the exam and testing is otherwise normal, the doctor may choose to monitor you without treatment at first. ...Read more
Yes: This is complicated and best discussed with your physician, as there are several possible causes. It (elevated intraocular pressure) can be caused by trauma, glaucoma, idiopathic (without cause) ocular hypertension, certain medications and other things that influence eye fluid (aqueous) production and drainage. ...Read more
Yes: One way is that it can interfere with eye fluid (aqueous) drainage, leading to increased pressure because the eye continues to produce fluid. ...Read more
