Intraocular pressure is pressure inside the eye. The continuous renewing of fluids in the eye causes intraocular pressure. Normal eye pressure ranges from 10 ? 21 mm Hg. Ocular hypertension occurs due to an increase in eye pressure. Open angle glaucoma, one of the leading causes of blindness in adults, occurs due to an imbalance of drainage fluid. This condition increases eye pressure. If this eye condition is not treated, it may damage the optic nerve causing permanent blindness. Xalatan eye drops are prescribed for reducing eye pressure in patients with open angle glaucoma. The medication is sold at Big Mountain Drugs and other Canada online pharmacies for discounted prices.
How the Eye Pressure Occurs
Eye pressure should be within a normal range for the proper functioning of the eye. The pressure in the eye occurs due to pressure exerted by fluids in the eye on the walls of the eyeball. There are two types of fluids in the eyes. These are the aqueous humor and the vitreous humor. Aqueous humor has a fluid-like consistency and is in front of the eye and the lens. Vitreous humor has a gel-like consistency and is behind the lens. Aqueous production and its outflow maintain the ocular pressure. Any problem with the production and drainage of the aqueous humor leads to ocular hypertension.
Diagnosing Eye Pressure
Intraocular pressure is checked by an ophthalmologist. This test helps identify the presence of glaucoma. The ophthalmologist may perform a number of tests. These include a Tonometry exam, Gonioscopy exam, Opthalmoscopy exam, and a visual field test and a pachymetry.
- Tonometry Exam ? The Tonometry exam enables the ophthalmologist to measure the eye pressure. This is done by numbing the eyes with eye drops and using a tonometer. The tonometer measures the cornea resistance pressure.
- Gonioscopy Exam ? The Gonioscopy exam enables the ophthalmologist a clear visual of the drainage angle of the eye. This is an essential examination for diagnosing glaucoma and the type of glaucoma.
- Opthalmoscopy Exam ? An opthalmoscope provides the ophthalmologist the ability to look into the optic nerve for any signs of damage. Eye drops dilate the pupils in order for the ophthalmologist to get a closer look at the optic nerve.
- Visual Field Test ? This is a test that helps identify the presence of glaucoma by checking for blank spots in the vision. This requires the covering of one eye while the other remains on a specified target. The visual field test is conducted with a perimeter.
- Pachymetry ? The pachymetry measures corneal thickness.
Lowering Eye Pressure
Ocular hypertension requires treatment. Damage to the optic nerve resulting in blindness is guaranteed without treatment. Treatment methods depend on individual cases and the measure of ocular hypertension. The most common method of lowering eye pressure is through medication. Most often, a patient diagnosed with ocular hypertension may be prescribed eye drops for lowering eye pressure. Xalatan is a popular eye pressure medication sold at Big Mountain Pharmacies. The medication works by aiding in opening drainage channels in the eye. The opening of the drainage channels enables the drainage of excess fluid, thereby, reducing eye pressure. The doctor may prescribe the number of times the patient may use the medication.
Side Effects of the Eye Drops
Side effects of the eye drops may be mild and tolerable. These include blurred vision, dizziness, dry or watery eyes, dizziness, eye discomfort, stinging or burning sensation etc. There may be some severe side effects of the eye drops. These include eye pain, infection, swelling, sensitivity to light, redness of the eyes and allergic reactions. These side effects require immediate medical attention.
Eye pressure increases the risk of glaucoma and blindness. The only manner of detecting eye pressure is through an eye check-up. Patients diagnosed with ocular hypertension, when prescribed with Xalatan, should purchase the eye drops through Canadian pharmacies for reduced prices.
