Glaucoma Eye Pressure Readings
In glaucoma can eye pressure readings vary if the same machine isn't used every time and there is a different doctor performing the reading?
Yes: Many variables affect pressure reading including the machine type, the method, the calibration, the operator, time of day, breathing and ocular perfusion, position, etc.See 1 more doctor answer
Corneal thickness is 510+ 2. In glaucoma does that mean you add 2 points to my eye pressure reading of 15?
No: The more important way to judge the pressure in the eye is whether or not there is any evidence of damage from pressure on the optic nerve head. The corneal thickness is a separate measurement the shows whether there is or is not an increased risk of developing glaucoma. Your measurement of 510 means that you do have an increase risk to developing glaucoma.See 1 more doctor answer
Glaucoma w/30% nerve damage. Pressure reduced from 30 to 15. Cornea is 516 thick. Do I add 2 points to eye pressure reading because cornea is thin?
Not really: The adjustments to pressure based on corneal thickness are largely out of favor today. The more important thing is to have regular pressure measurements by the same technique. If you went from 30 to 15 with treatment, you are doing very well.See 1 more doctor answer
My optometrist says I don't have damage but glaucoma specialist says I do. Who is right? Eye pressure readings and field test vary between offices
I've been diagnosed with glaucoma. Thirty years ago I had a problem with chronic eye infections. I was also treated for high intra-ocular eye pressure readings. Is it even a remote possibility that the eye infections affected the drainage systems of the
No,: No, this is very unlikely, unless the infections were actually a form of inflammation inside your eye, known as uveitis or iritis. The drainage system that is involved in pressure control of the eye are inside the eye, and eye infections generally affect the inside of the eye.See 4 more doctor answers
Maybe: Glaucoma means the pressure in the eye over time has caused damage to the optic nerve. Increased eye pressure is a risk factor for glaucoma but it does not necessarily mean you have it. Examination and evaluation by an eye md can help determine if you have glaucoma or are at risk of glaucoma and if treatment is needed.See 2 more doctor answers
Yes: Possibly so - other factors such as age and actual pressure readings will play a role in your specific risk for developing glaucoma. It would be wise to follow up with an eye specialist and understand your risk and recommendations for risk reduction through intra-ocular pressure control.See 2 more doctor answers
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.See 2 more doctor answers
Per doc schedule: May return right away if iop very high if start new therapy may check in 1 mo if stable, may check every 3-4 mo if suspect, may check every 6-12 mo.See 1 more doctor answer
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.
No: Not all increased eye pressure results in glaucoma. Ocular hypertension is considered a glaucoma suspect and is followed until progressive optic nerve damage is detected, which can be a different pressure for different patients. Various ethnicities define elevated eye pressure with different cutoffs.See 1 more doctor answer
0-70: Minimum 0 mmhg when the eye is completely collapsed and too much fluid is exiting the eye for the amount made. Maximum somewhere around 70 mmhg since eventually the eye can't make any more fluid (ischemic ciliary body). With repeated injections, you may be able to make the eye pressure higher. Glaucoma is when the pressure causes retinal ganglion cell loss (a different number for everyone).See 3 more doctor answers
If my eye pressure has come out to be 24, is it for sure that I have glaucoma. If yes, then how can it be treated.?
Not definitive: Glaucoma is a condition in which the eye pressure exceeds the ability of the circulation in the back of the eye to withstand it. A pressure of 24 is normal for some. If you have no field loss, thick corneas and healthy looking discs, then you probably have nothing to worry about. Get a second opinion with an ophthalmologist to see what your status is.See 5 more doctor answers
In glaucoma if target eye pressure is met, is it possible pressure won't need to be lowered further so that adding a 2nd drop won't be necessary.
Expert Dr. Said glaucoma progressing too fast, but eye pressure is sufficiently lowered & nothing else he can do. Should I accept or get 2nd opinion?
