What are the different types of glaucoma screening tests?
different types of test screening of glaucoma include a commonly carried out air barrel test that measures intraocular pressure and an optical nerve damage test and a field of vision. Doctors also often measure the thickness of the cornea, perform gonioscopy and use optical nerves. Most of the available glaucoma screening tests are painless, harmless and quickly administered to patients in the Optometrist office, often as part of a routine annual eye test.
The air cloud test is the most common of glaucoma screening tests and is usually served during routine eye tests. The patient looks at a device that resembles a telescope and focuses on small light. The device releases the controlled air explosion that hits the eye surface and measures the eye resistance to air pressure. This allows optometrists to measure how much pressure is inside the patient's eyes.
The eye pressure can also be measured using an application tonomer in which the patiento is anesthetic and the optometrist touches the surface of the eye to urHe lived how much pressure is needed to align the cornea. Doctors also use the electronic indentation method. This procedure performs the same task with a digital tool similar to a pen that is also used to push the eye surface.
Patients with strong cornea may have eye pressure values that are higher than usual, even if they do not have glaucoma. A strong cornea can also mask glaucoma. Glaucoma screening tests, such as pachymmetry, use an ultrasonic wave tool to measure the patient corneal thickness. Determination of corneal thickness can help increase eye pressure assessment.
Ophthalmoscopy is a screening test of glaucoma that begins with pupils' dilation. Once the pupil is enlarged sufficiently, the doctor can look into the eyes and explore the back of the Eyeballs. Any damage to the optical nerve will usually be visible. The field of vision can also help determine whether the patient suffers from glaucoma assessment of his peripheralhim to see him.
other tests of glaucoma screening include displaying gonioscopy and optical nerve. Gonioscopy involves examining the front of the eyeball to see if the iris is closer to the rear of the cornea than it should be. If so, a closed angle is likely to diagnose. Optical nerves can be some of the four methods of displaying used to document optical nerve changes that occur over time: scanning laser polarimetry, confocal scanning laser ophthalmoscopy, optical coherence tomography and photos of discs.
glaucoma is not only the condition of the eye, but a group of related diseases caused by damage to the optical nerve. This optical nerve damage is usually caused by an unusually high pressure inside the eye. Loss of vision caused by glaucoma may be as gradual that patients rarely noticed this symptom by the undokud disease will not understand the disease. Glaucoma screening tests are essential because early diagnosis and interventions mayourselves to reduce the damage to the optical nerve and even prevent the loss of vision.
