I heard that target eye pressure for most glaucoma patients should be 14 - 15. Is that true?

I heard that  target eye pressure for most glaucoma  patients should be 14 - 15. Is that true?

Some variation: Normal eye pressure range is 10-21. Glaucoma is when eye pressure exceeds eye resistance to that pressure and varies with the individual case. 14-15 is generally a good target for most cases but some require a lower pressure and some can tolerate higher pressures. Your optimum can be decided with the help of your ophthalmologist. ...Read more

Glaucoma (Definition)

Glaucoma refers to a group of eye conditions that lead to damage to the optic nerve, the nerve that carries visual information from the eye to the brain. In many cases, damage to the optic nerve is due to increased pressure in the eye, also known ...Read more

Can caffeinated tea or coffee increase eye pressure in glaucoma patients?

Can caffeinated tea or coffee increase eye pressure in glaucoma patients?

Unlikely: Factors that affect intraocular pressure are varied and multifactorial and not completely understood. Effect of caffiene probably negligible. ...Read more

What eye pressure do doctors start patients on eye drops to prevent glaucoma?

What eye pressure do doctors start patients on eye drops to prevent glaucoma?

Depends: Every patient needs a risk analysis of the various risk factors. Based on that analysis a target pressure is determined. As a group only about 10% of patients with IOP 24 or greater will develop glaucoma therefore not all patients with elevated need to be treated. I have many patients with elevated pressure that I have followed for decades who have not developed glaucoma. ...Read more

At which eye pressure do doctors start patients on eye drops to prevent glaucoma?

At which eye pressure do doctors start patients on eye drops to prevent glaucoma?

It depends...: on the individual. If the glaucoma is early, moderate, or severe, then the target eye pressure will be set according to the appearance of the optic nerve, visual field test, and a number of other tests for glaucoma. Typically though, if the pressure approaches the mid to upper 20s or higher, treatment is usually started. ...Read more

Would an eye transplant work for a glaucoma patient?

Would an eye transplant work for a glaucoma patient?

Not really...: In complicated situations, such as eye injury or infection, the loss of vision can be caused by several simultaneous processes. For example when the clear cornea has been damaged, and there is glaucoma as well, a corneal transplant (with cataract or glaucoma surgery as well) may help improve vision.... But this is not technically an "eye transplant for glaucoma.". ...Read more

Does flying on an airliner changer the eye pressures in glaucoma?

Maybe a little: Altitude can cause changes in eye pressure, but most commercial airplanes are pressurized to less than 8000 feet and private planes generally don't go high enough to make a difference. Whatever the case, the duration of most flights is so short that it shouldn't make a difference. Glaucoma damage takes years to develop and a short spell of elevated pressure is not worrisome! ...Read more

Could glaucoma eye pressure test be done before eye dilation?

Could glaucoma eye pressure test be done before eye dilation?

Yes: Intraocular pressure should always be measured prior to dilation as it typically increases a little after dilation, especially when monitoring for glaucoma. There are a few conditions where it may be checked after and eye doctors will typically recheck pressures after dilation to ensure accuracy of their technician, but as a rule, this should be documented prior to dilation. ...Read more

Can having sinus congestion affect glaucoma pressure in an eye?

Not really: Sinus congestion can be quite unpleasant but the pressure in the sinus is not transmitted to the eye. These are separate and independent problems. ...Read more

Does having sinus congestion also affect the glaucoma pressure in an eye?

Does having sinus congestion also affect the glaucoma pressure in an eye?

No: Sinus pressure can be felt around the eye, often making a patient think the pressure in the eye is elevated. Sinus congestion has no affect on intraocular pressure. ...Read more
