It has been my experience, and the advice from my two eye docs, that it is healthier for the eyes to use the CPAP and benefit from it overall than to not. I was very concerned about this because my eye pressure in my left eye had been steadily rising and changes in the optic nerve was happening. When I mentioned if I should stop use or decrease the CPAP pressure even if it meant less quality treatment, both doctors practically shouted no. It was their opinion (I did not see them both at the same time but on 2 different appts) that my eyes were healthier due to the oxygen I was keeping in my system because I was treating my sleep apnea.

If the use of the device does raise the eye pressure, it typically decreases once the person awakes and the CPAP is turned off. One study done on just 21 patients who were new users and were followed for just one month. Other eye conditions caused by untreated OSA improve or go away with the use of CPAP. The exception is anything to do with eye pressure but not enough studies (just the one) have been done to determine anything else.

The diagnosis of glaucoma does not happen until damage has been done to the optical nerve. One can have ocular hypertension for years and not have damage, which is what I have been experiencing. And, as the OP has said, one can have ocular hypertension and it not be "real" glaucoma (typically caused by blocked drain pipes or by changes to the optic nerve itself).

The reason I believe using a CPAP is better for a person with ocular hypertension than not using it, is simple: the eyes are not the only part of the body that is being strained. Sleep Apnea effects the entire body, every cell, every organ, every system. To not treat sleep apnea is an un-smart thing to do. Oxygen and sleep deprivation is harmful to everything, not just the eyes. The benefits far outweigh the risks.

Thankyou for this post Paula...ThanksThanks

RE: Cpap & Glaucoma
I appreciate everybody's viewpoints on this. Talked to my ophthalmologist this morning. I don't think he was all that familiar with this issue, but is educating himself now. I told him that I was still going to use the cpap (for all the reasons Paula02 and others have said), but that my primary concern was which masks to avoid other than the full face mask (like Fitlife). He wants me to just select a mask that works for me and come in for eye pressure checks (as they already know my baselines). He also said to talk to the sleep doctor about it, which, of course, I planned to do.

What this tells me is that this issue is a bit under the radar even for glaucoma specialists. Perhaps not enough study has really gone on about it. OR... the doc simply thinks I'm unnecessarily focused on this concern, which he considers minor, in the scheme of things. As mentioned earlier though, my situation is the opposite of many with glaucoma. I have higher eye pressure because of high intracranial pressure, and the studies do show that CPAP does help to lower this pressure. I might send an email to my other eye specialist and see what he has to say on the mask issue.

RE: Cpap & Glaucoma
I do not have glaucoma, but my eye pressures have been consistently on the high end over the last few years. Now that I started cpap, my eye pressures have actually dipped into the normal range. Not sure if it's directly related, but I'll take it.

That point is well taken. Now let me ask you a different question:

Did you read the rest of my post or just that one sentence? (OK, maybe not so different after all)

Because it appears that you did not, while I certainly did read yours. Twice.

You are welcome to your opinion about what might be more dangerous or more healthy, and I might even agree with you, but you would probably not even realize that because of how you might be forced to answer the question above, if answered truthfully.

Still, what you put forward is an opinion, and only an opinion.

I do not deal in opinions, because opinions often do not matter. I deal in facts, because they always matter, and usually, a whole helluva lot more than any opinion.

I was not disputing your opinion, again which I might even agree with; I was disputing what were presented as facts, in the most possible non-confrontational manner available. And after carefully rereading your post out of courtesy to you, I stand fully and vigorously by my answer, which is that one does not negate the other; both are separate phenomena and both are something to be taken into account. The last part of that last statement might also be an opinion, but the first part (both before and after the semicolon) is definitely none other than a fact.

And the only reason I deferred to the facts over opinion in the first place is because I have an opinion too, which is that I consider it irresponsible to ignore these facts when someone's health is at stake and they could easily be convinced by opinion instead of facts. I was doing exactly the right thing, and I'd do it again in a New York minute.

If you use CPAP, intraocular pressure increases. That actually IS a fact, if you believe the studies that were done on this. And CPAP improves 02 flow which has many positive results; that too is a fact.

CPAP increases intraocular pressure. CPAP also aids the flow of 02 to the retina and everywhere else that blood flows. Both are facts, and both exist. What is not a fact is that one negates the other. It doesn't.

That you may hold an opinion that one approach may be healthier than the other isn't even an argument against what are the facts, because your opinion has to do with how healthy one thing is as opposed to another, while what I am stating is that CPAP raises intraocular pressure, regardless of whether one or the other approach is healthier.

And whether your opinion reflects truth or not is not the question. But the question is also not whether your opinion invalidates what are the facts. An opinion never invalidates the facts, which is why it is called an opinion, and not a fact.

But there are no facts supporting that using CPAP actually negates the fact that using CPAP increases intraocular pressure, or that improving 02 flow by using CPAP which has been proven in studies to increase intraocular pressure, negates the side effects of that. And that in itself is also a fact, and not an opinion.

You may think they negate each other, but thinking that is so does not make it a fact, it only makes it an unsupported, unfounded opinion, held, so far, by three people.

The facts will still exist, regardless of opinion.

Opinions can be important. I value your opinion. But facts are undeniably more important, and certainly more valuable than any opinion, which they will always very greatly outweigh.

And that's a fact.

RE: Cpap & Glaucoma
As a person who suffers from closed angle glaucoma, and has just had laser surgery on each eye to reduce IOP, I have been most interested in this thread.

The great internet is not really a very good place to find unbiased medical opinion, IMHO, however I wanted to see if there were any reasonable, to me, arguments regarding CPAP and glaucoma out there in the cloud as it were.

I found this magazine:
http://glaucomanow.com/media/17219/glaucomanow_issue1_2013.pdf
Page 9 is the page of interest,

also this study seemed good, it is very long, but good detail:
http://www.nature.com/eye/journal/v24/n5/full/eye2009212a.html

I am seeing my eye surgeon soon and will bring up the topic of CPAP and Glaucoma. I am sure it will be an enlightening conversation for us both.

But the main take away from my reading today, for me, has been that if you have OSA you should have your eye pressures checked regularly, not just for/or because of Glaucoma, but because sometimes the pressures are raised, sometimes not and it is better to be safe than sorry...IMHO....Sleep-wellSleep-well
