Low Intraocular Pressure Symptoms
Often none: With slow pressure rises from open-angle glaucoma there are really no symptoms only late vision loss. With acute closed-angle glaucoma there is pain and pressure with a red eye. Often patients notice "steamy vision" with rings around lights from corneal swelling from the high pressure - this is an emergency. ...Read more
Generally no: The normal eye pressure range is 10-21. Anything above this might be elevated but you will not feel that elevation until the value reaches the high 40's or above. This is why pressure should always be taken when you visit your ophthalmologist as the feeling of pressure is not a clue for the patient. ...Read more
Different ways: Commonly, goldmann applanation with the blue light or air puff pneumotonometer. We also use tonopen, icare, pascal, reichert's, perkin's, and palpation depending on the cornea status. Schiotz is rarely used anymore. ...Read more
Mm Hg: Or torr.Get a more detailed answer ›
Agree: The one thing worth mentioning is that the effect of exercise is typically transient - to enjoy the lowering iop effect, the exercise must be done on a regular basis. All types of exercise (aerobic, isometric, etc) seem to have some benefit. ...Read more
Normal IOP 10-20: Intraocular pressure (aka IOP) usually runs between approximately 10 and 20 mm Hg. It is frequently elevated in glaucoma, although not always. A pressure of 22 is elevated, although like with blood pressure there can be fluctuations. If you have no family history of glaucoma, I would recommend a recheck in 6 months. If you do have a history, I would have it rechecked in 3 months. ...Read more
Glaucoma is uncommon:
Your eye pressure is usually normal.
Elevated pressures that are too high for too long can hurt the delicate eye tissue.
The nerve can die and the vision can be lost.
You can have the pressure measured easily at the eye doctors office.
The test is simple and no pain

Great question: We know high IOP is the biggest risk factor, but other than that, genetics, aging, certain ethnicity (African American, Latino, Asian), thin corneas, high myopia, migraine, raynauds, systemic hyper- or hypotension, diabetes, chronic corticosteroids, eye injury, inflammation, & probably many more (yet to be determined) factors. Early detection w/ a comprehensive eye examination beginning under 40. ...Read more
Many treatments: Your Eye physician determines which treatment would seem most appropriate for lowering intraocular pressure in your eye. This determination is based on disease severity, health factors& desired target range of intraocular pressure. Treatment may range from eye drops (1 or more types), oral medication (rare), laser, to incisional glaucoma surgery. Most often, 1 or more of these treatments will work ...Read more
NO: Typically not, the normal range is usaully between 7-21 mm hg. 25 may be normal for some people though and may not cause a problem, glaucoma. 25 may also be artifically elevated due to a thicker than average cornea (which may affect the measuremant of intraocular pressure), this can be a normal variant (thick cornea). ...Read more
Exercise: Exercise is the only natural way that I know of that is supported by research. ...Read more
None: There is no known way to prevent iop to increase (other than medications). ...Read more
None known: Since, in most cases, the cause of increased intraocular pressure is unknown, we also do not know any ways to prevent it from rising. The best course is to follow your ophthalmologist's plan to monitor and manage the pressure. ...Read more
A range: The generally accepted range is 10 to 21 mm hg as measured by standard instrumentation such as the goldmann tonometer and other devices. ...Read more
Yes: Succinylcholine does increase intraocular pressures for about 20 minutes after administration. ...Read more
Schiotz tonometer: I commonly use a sterilized schiotz indentation tonometer in a sterile field. The accuracy is fair, but the instrument can be sterilized and will not compromise the sterile field. ...Read more
How often should I have my intraocular pressure checked? I have intraocular hypertension. Once/yr. Doesn't seem enough, after checking every 6 months.
Depends: If you have a long history of stable pressure and normal visual fields and normal corneal thickness and normal nerve fiber thickness on hrt/gdx/oct testing and you do not have diabetes and you are not african american and you are not asian then twice a year would be good depending on how high the pressure is. Three times a year will keep you on a short leash but will keep you very safe. ...Read more
How does levodopa/carbidopa cause a rise in intraocular pressure? I understand that it can cause an acute rise in that pressure but how?
Ok to take an SSRI (Paxil (paroxetine) 20 mg) with history of elevated intraocular pressure and 'glaucoma suspect' status? Thanks
Best ask Eye Dr.: The provider assessing your eye issues is the best by far to ask about this. It's very good that you are thinking of it before doing it. We wish more folks would! With so many on SSRIs now, they must have had experience with the impact on such eye issues. Good luck w/ finding the best views on this. ...Read more
In davinci hysterectomy with glaucoma what is the safest degree of tilt in the Trendelenburg position to eliminate rise in intraocular pressure.
No exact number: There is not an agreed upon number. Each case should be reviewed on a case by case basis. Your Gyn surgeon may want to send you for preop clearance by your eye doctor to determine if you are a candidate for Robotic surgery. Eye injury from trendelenberg is rare but it can occur. Your gyn surgeon will also need to determine if your case can be done robotically if steep trendelenberg is not approved ...Read more
Hi IOP after CE: If corrected intraocular pressure > than 21mmHg, have eyeMD check position of IOL to be sure haptics are in correct position, no uveitis, do gonioscopy to be sure IOL haptics not touching eye drain/no foreign body. If all ok, pressure lowering drops are 1st used; po pills sometimes needed; if not helping, a laser procedure to open more holes in drain can be tried; last resort: trabeculectomy, tube ...Read more
