![]() ![]() A variety of medications are used to treat ocular hypertension. Treating Changes in Eye PressureĬhanges in eye pressure that do not affect vision may not need to be treated, unless the patient is at risk for glaucoma. These tests may include ophthalmoscopy, perimetry or visual field testing, pachymetry, and optical coherence tomography. If abnormal intraocular pressures are detected, then you may need more specialized tests to determine your risk of developing eye disease. No instruments will touch your eye, so you won’t need an anesthetic. Your doctor will warn you to expect a quick pulse of air, which may be surprising. This test estimates the pressure in your eye using a puff of air. Before the test, you’ll receive anesthetic drops to numb the eye, so you won’t feel anything. The tonometer is briefly placed on the cornea to determine eye pressure. Your eye doctor may put fluorescein, the same dye used during a slit lamp examination, in your eye to make it easier to see. This test measures the amount of force needed to temporarily flatten a part of your cornea. Your eye doctor may use one of the following tonometry methods to measure intraocular pressure: ![]() If glaucoma is a concern, your eye doctor will also carefully examine your optic nerve for signs of damage. A diagnosis of glaucoma will require more than just eye pressure measurement because it is possible to have glaucoma and have normal eye pressure. The test most commonly used to measure intraocular pressure is tonometry, which is often used to screen for glaucoma. Eye surgery, especially cataract surgery.Underlying eye condition, such as pseudoexfoliation syndrome, pigment dispersion syndrome, or corneal arcus, or a thin cornea.Long-term use of certain medications, in particular corticosteroids.Inadequate or increased aqueous drainage.Excessive or decreased aqueous production. ![]() What Is Causing Changes in Your Eye Pressure?Ĭhanges in eye pressure may be caused by: Hypotony may be treated with a variety of techniques, depending on the cause. While some persons may have visual symptoms at 10 mm Hg, others may have no symptoms at 6 mm Hg. The risk of vision problems increases when eye pressure falls below 6 mm Hg, although this number can vary. When eye pressure is too low it can cause problems with vision. ![]() Hypotony: When intraocular pressure is less than 8 mm Hg, a person is considered to have hypotony. If the condition continues to progress, permanent eye damage and blindness can result. Glaucoma typically causes no pain and produces no symptoms, but if left untreated it can eventually affect peripheral vision. They suffered from arterial hypertensionĪlthough hypertension is a risk factor for glaucoma, you can have higher than average eye pressure and not have glaucoma.In a study published in the European Journal of Ophthalmology, researchers found that patients with intraocular hypertension had a higher risk of developing open-angle glaucoma if: Ocular hypertension is a risk factor for glaucoma, a disease that damages the optic nerve. Although ocular hypertension can affect anyone, it may be more common in persons with certain risk factors. What Is Ocular Hypertension?Īn increase in blood pressure is called hypertension, and an increase in intraocular pressure is called ocular hypertension.Īn eye is considered to have ocular hypertension if intraocular pressure is consistently 21 mm Hg or higher. For this reason, going to the eye doctor regularly is important, as eye pressure changes can be detected during a routine office visit. Abnormal intraocular pressures usually don’t cause symptoms. Intraocular pressure varies with changes in heart rate or respiration, and may also be affected by exercise and fluid intake.Īlcohol consumption and caffeine use also cause temporary changes in intraocular pressure, as can coughing, vomiting, or straining to lift heavy objects.Ī significant change in intraocular pressure that persists and remains untreated can eventually cause vision problems and lead to eye disease. Slight changes in eye pressure from one season to another - or even during the course of a day - are normal.Ĭhanges in intraocular pressure can be caused by anatomical problems, inflammation of the eye after trauma or infection, genetic factors, and medication use. Intraocular pressure is the tissue pressure within the eye, which is determined by the balance between the production and drainage of aqueous humor, the clear fluid inside the eye. ![]()
