intraocular pressure

I can sense elevated intraocular pressure

Submitted by Suekay on Sat, 01/30/2010 - 6:54pm

Glaucoma is known as the silent thief of sight because (in its common forms) there is no pain and no other symptoms until the damage has been done.

I don't have glaucoma, I have high IOP due to prolonged use of steroid drops. I know when the pressure is high, I can feel it. Firstly I get a pulsing, this means the pressure is up to about 25-30 then I get feelings of pressure and lastly if i blink fast I can see black striations in the shape of my iris.

Using lemon to lower my eye pressure from 21 to 14

Submitted by manasbahi on Sat, 01/30/2010 - 6:48pm

I do use once a week lemon drop, it has rules to do it. the lemon should be fresh and you cut it with a clean knife , and it should be at night before bed time. I squeeze one drop in each eye. and when Iwent to the dr. it droped from 21 to 14 which is great. I know it hurts a lot for few seconds then I feel cool in my eyes. " I wonder if anyone tried this"? I got the from my 90 years aunt who died and she had 20/20 eye vision and can thread the string in the needle.

Consciousnes and Eye Pressure - further thoughts

Submitted by bstruss on Fri, 01/22/2010 - 1:17pm

 Here is what i have noticed after several months of recording my eye pressures. 

  • I can sometime detect an immediate correlation between a 'negative' or stressful thought (or anxiety) and an increase in my eye pressure.

Kindness As A Tool for Managing Eye Pressure

Submitted by dave on Wed, 01/20/2010 - 1:26pm

Yesterday I saw some discussions that reminded me of the profound discovery I made several years ago in my own intraocular pressure data. I observed, time and time again, that simply disagreeing with another individual in an online forum would raise my intraocular pressure. (This effect does not require arguing -- simply disagreeing in a polite manner is often enough.) This is a universal phenomenon.

Panic attacks, adrenal exhaustion, eye pressure and consciousness

Submitted by dave on Sun, 01/17/2010 - 2:01pm

FitEyes post about the healing power of consciousnessLow blood pressure can be a problem for glaucoma patients because it results in insufficient blood supply to the optic nerve.

A lot of glaucoma patients suffer from anxiety, stress, panic attacks and other similar issues. Those issues lead to adrenal fatigue and adrenal exhaustion. And adrenal fatigue/exhaustion can lead to low blood pressure (hypotension).

Sleeping position alters intraocular pressure

How we sleep can raise or lower IOP

Patients with glaucoma often ask what they can do to favorably impact their disease. These patients are eager to engage in beneficial activities and to avoid detrimental activities to save their optic nerve from glaucoma. Unfortunately, most of glaucoma’s known risk factors are not modifiable—such as age, race, and family history. In glaucoma management, there is little credible data supporting any role of nutritional supplements, avoidance of certain exposures such as caffeine or smoking, or alternative interventions such as acupuncture. Doctors’ standard answer is usually to encourage patients to continue using their medications as prescribed and to keep their follow-up appointments faithfully.
Some new research presented at the May 2009 annual meeting of the Association for Research in Vision and Ophthalmology, Ft. Lauderdale, Fla., suggests that there may be a new modifiable risk factor within the patient’s ability to control: sleeping position.

Caveat: this article ignores ocular perfusion pressure. It is quite possible that the conclusions discussed in this article are incorrect. Sleeping with the head elevated may reduce IOP but it may also reduce blood flow to the optic nerve (and brain) and thereby reduce ocular perfusion pressure. It is quite possible that sleeping with the head elevated may do a glaucoma patient more harm than good. But read the article for one perspective.

Detective Work Required - Eye Pressure Going Up While On Relaxing Vacation

Submitted by dave on Sat, 12/26/2009 - 2:31pm

For many glaucoma patients, a vacation can present an opportunity to do some good thinking, maybe reflect on our direction in life or mentally solve some important questions that have been in the back of our mind but ignored because of our busy schedules.

Intraocular pressure too low after trabeculectomy

Submitted by Anonymous (not verified) on Thu, 10/22/2009 - 6:13pm

I had a trabecelectomy 3 months ago, 3 stitches were lasered afterwards and
my pressure was low, but not too low..since i lost considerable vision in
that eye, my doctor was satisfied..However, the pressure has gone too low and
he is trying a pressure patch, otherwise, suggests surgery to add another
stitch.. Any input??or similar experiences?? I really dont want another
surgery..

Fluctuating Intraocular Pressure

Submitted by Agnes on Sun, 10/11/2009 - 1:09pm

NOTICE: If you are engaged in self-tonometry and you have questions about your daily intraocular pressure fluctuations, you should read this comment about the difference in the way fluctuations are defined by mainstream ophthalmology and the fluctuations we observe in self-tonometry.

I will further preface this article by saying that I do not believe there has been a study done where subjects with normal, healthy eyes performed self-tonometry the way we are doing it.

I urge caution in comparing self-tonometry data against the data being discussed by Dr. Rick Wilson below.

It is good to try to understand as much as we can. However, I believe it is not good to misinterpret your own self-tonometry data -- or to jump to incorrect conclusions based on the apples and oranges fallacy.

On Wednesday, May 18, 2005, Dr. Rick Wilson a glaucoma specialist at Wills, and the glaucoma chat group discussed "Fluctuating IOP's."

Moderator:  Tonight's topic concerns fluctuating intraocular pressures (IOPs).  In a recent chat, you said studies have shown that fluctuating IOPs are more of a risk factor than a somewhat higher, but steady IOP.  Why is that?

 

Dr. Rick Wilson:  We are not sure. Several studies have shown glaucoma patients do not auto-regulate their circulation as well as patients without glaucoma.  In other words, if a patient's blood pressure increases suddenly, it pushes more blood into the eye, and the added blood flow and pressure cause more aqueous to be made.  A normal eye would sense the change and constrict the blood vessels to reduce the flow of the blood under higher pressure back to normal.

 

P:  Is that called "autoregulation?"

 

Dr. Rick Wilson:  Correct. Autoregulation should take place with decreased blood flow or pressure, increased metabolic needs of the eye, etc.  Clearly, a fluctuating IOP requires the eye to continually auto-regulate the blood flow to keep the optic nerve well supplied with oxygen and nutrients.  That may be onerous for the glaucomatous eye.

 

P:  Isn't some amount of IOP fluctuation normal even in healthy eyes?  For example, aren't pressures expected to be higher in the morning than in the later part of the day?  In any case, how much of a spread in IOP is considered normal?
