The key to Glaucoma Prevention is regular eye exams by detecting glaucoma early enough for successful Glaucoma Treatment.
It’s best to have routine Eye Care Exam checkup, every 2 to 4 years after age 40 and every 1 to 2 years after age 65.
If you’re at increase risk, you doctor may recommend more frequent monitoring.
Remember nothing beats a healthy diet with the right balance of Vitamins and Minerals when it comes to preventing an eyesight problem.
A Test to detect Glaucoma and help with Glaucoma Prevention:
Tonometry is a simple, painless procedure that measures your intraocular pressure. It is usually the initial screening test for glaucoma prevention.
Two common techniques age air-puff Tonometry and applanation tonometry.
Air puff tonometry uses a puff of air to measure the amount of force needed to indent your Cornea.
An applanation tonometry is a sophisticated device that’s usually fitted to slit lamp.
For this extremely accurate test, your doctor numbs your eyes with drops and has you sit in front of flit lamp, where a small flat tipped cone pushes lightly against your eyeball.
The force required to flatten (applanate) a small area of your cornea translates into a measure of the IOP.
Test for optic nerve damage:
Your doctor may also use laser light and computers to create a three dimensional image of your optic nerve.
This can reveal slight changes that may indicate the beginnings of glaucoma.
Visual field test:
To check how your visual field has been affected by glaucoma, the doctor uses a perimeter test.
One method, known as tangent screen perimetry, requires you to look at a screen with a target in the center.
Your eye doctor manipulates a small object on a wand at different location in your visual field.
You indicate whenever you see the object come into view. By repeating this process over and over again, the doctor can map your entire visual field.
To distinguish between Open Angle Glaucoma prevention and acute Closed Angel Glaucoma prevention your eye doctor may use a technique call gonioscopy (goe-nee-os-kuh-pee), in which a special lens is placed on the eye to inspect the drainage angle.
Tomography, can measure how fast fluid drains through he trabecular mesh work.
To receive a diagnosis of glaucoma, a person must exhibit several factors.
These include an elevated IOP, areas of Eyesight Loss and damage to the optic nerve.
In glaucoma, the optic disk will show visible signs of damage.
The optic disk is the area where all the nerve fibers come together at the back of the eye before exiting the eyeball.
An optic disk that has been affected by glaucoma appears indented, or excavated, as if someone scooped out part of the center of the disk.
This condition is known as cupping. The normal contour and color of the disk may be affected by the loss of nerve fibers.
If your doctor determines that you have elevated IOP, an excavated optic disk and loss of visual field, you’ll likely be treated for glaucoma.
If you have only slightly elevated eye pressure, an undamaged optic nerve and no visual field loss, you may not need Glaucoma Treatment but more frequent examinations this may be advised to detect any future changes.
If you have signs of optic nerve damage and visual field loss, even if you eye pressure is in the normal range, you may be treated to lower eye pressure further, which may help slow the progression of glaucoma.
Remember the key to Glaucoma Prevention is regular Eye Care Exams.
