Question 1

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?

Accepted Answer

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.

Question 2

corneal  thickness is 510+ 2. in glaucoma does that mean you add 2 points to my eye pressure reading of 15?

Accepted Answer

Generally yet: There is a nomogram relating corneal thickness to internal pressure and at a thickness of 510 (on the thinner side) the pressure estimate is 2 points higher.  If your eye pressure is 15, that is comfortably in the normal range.  Are you being treated to lower your pressure to that level?

Question 3

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?

Accepted Answer

Yes: Because the cornea is thin, your actual eye pressure is 2 points higher than measured.

Question 4

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

Accepted Answer

Get third opinion: This is a case where i would normally side with the glaucoma specialist, but you will never be convinced you received the correct diagnosis. I would advise you seek a third and final opinion from another ophthalmologist.

Question 5

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

Accepted Answer

Doubtful---glaucoma : Doubtful---glaucoma can effect anyone particularyly as they age.  Thankfully with good treatment you should not lose any vision to the disease.

Question 6

what are the causes of high eye pressure, besides glaucoma?

Accepted Answer

Contradictory quest: The definition of glaucoma is elevated pressure that causes optic nerve damage. So if there is anything that results in increased eye pressure that causes nerve damage then that is by definition glaucoma. Better to ask what causes nerve damage besides glaucoma, there are many causes such as atherosclerosis, high blood pressure, many other systemic conditions.

Question 7

how often should you have eye pressure checked in glaucoma?

Accepted Answer

Depends: On type of glaucoma, whether well controlled or not, whether starting new treatment.  Range varies from every 5 minutes to every year!

Question 8

what are the causes of high eye pressure other than glaucoma?

Accepted 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.

Question 9

does increased eye pressure mean that i have glaucoma?

Accepted Answer

No: If you are told you have increased eye pressure, you should get a glaucoma eye exam to confirm the elevated reading and to test for glaucoma formally.

Question 10

can i develop glaucoma without increased eye pressure?

Accepted Answer

Yes: Patients with glaucoma without increased eye pressure are commonly called "normal tension glaucoma" or "low tension glaucoma."  glaucoma is multifactorial and probably involves more than just eye pressure, i.e. Ocular perfusion pressure, neurosusceptibility, etc.
