Perimetry is a visual field test that produces a map of your complete field of vision. this test will help a doctor determine whether your vision has been affected by glaucoma. during this test, you will be asked to look straight ahead as a light spot is repeatedly presented in different areas of your peripheral vision.

The visual field test is a subjective measure of central and peripheral vision, or side vision, and is used by your doctor to diagnose, determine the severity of, and monitor your glaucoma. the most common visual field test uses a light spot that is repeatedly presented in different areas of your peripheral vision. less common testing may be performed by a technician manually moving a target to map areas of damage. Glaucoma tests are a group of tests that diagnose glaucoma, an eye disease that can cause vision loss and blindness. there is no cure for glaucoma, but early diagnosis and treatment may help protect against serious vision loss. learn more.

Glaucoma Symptoms And Signs Causes
Glaucoma is a type of eye disease that affects the optic nerve and causes vision loss. most types of glaucoma are due to elevated pressure inside the eye, called intraocular pressure (iop). there are two main types of glaucoma: angle-closur. A visual field test is performed at the initial visit or as soon as glaucoma is suspected. it evaluates vision loss due to glaucoma, damage to the visual pathways of vision test glaucoma the brain, and other optic nerve diseases. when glaucoma is diagnosed the visual field data is used to determine the severity of disease.

Ophthalmoscopy is used to examine the inside of the eye. ophthalmoscopy can be performed on a dilated or undilated eye. an eye doctor uses special magnifying lenses and medical devices to view the optic nerve. the color, shape and overall health of the optic nerve is important in glaucoma assessment. the doctor may also use a digital camera to photograph the optic nerve. sometimes, stereo photographs are taken to give a 3-dimensional picture in order to better assess the overall shape of the optic nerve. pachymetry is the method of measuring the thickness of the cornea. although research is still being conducted on the importance of corneal thickness, pachymetry is starting to play a larger role in glaucoma testing. the thickness of the cornea seems to influence the eye pressure reading when tonometry is performed. The visual field test is a subjective measure of central and peripheral vision, or “side vision,” and is used by your doctor to diagnose, determine the severity of, and monitor your glaucoma. the most common visual field test uses a light spot that is repeatedly presented in different areas of your peripheral vision. A visual field test is performed at the initial visit or as soon as glaucoma is suspected. it evaluates vision loss due to glaucoma, damage to the visual pathways of the brain, and other optic nerve diseases. when glaucoma is diagnosed the visual field data is used to determine the severity of disease. this staging information is useful in choosing a target intraocular pressure and determining follow-up. after the initial diagnosis the doctor will repeat the visual field test to check for worsening disease. this may be done in three to twelve months depending on the severity. if there are worsening defects or new areas of damage, a lower intraocular pressure and change in therapy may be needed. many studies have shown that visual fields are variable over time and there is a learning curve when taking the test, so your doctor may ask you to repeat the test to confirm your results. imaging of the optic nerve and surrounding tissues is an objective test that can also detect glaucoma damage and progression. this information can help your doctor make treatment decisions, and as the technology improves it will be even more useful. however, at this time it has not replaced the visual field test. we still need both types of testing because there are times that the optic nerve changes before the visual field, but also times when changes to the visual field are observed before damage to the optic nerve is detected. If you have glaucoma, you know that the main goal is to prevent damage to the optic nerve. if undetected or untreated, this can cause irreversible damage to the eye. that's why it's important to find the best treatment of glaucoma for you.
A complete eye exam includes a check for glaucoma. glaucoma is an eye disease usually caused by having elevated pressure in the eye. glaucoma can cause vision loss, often without any warning signs or symptoms. regular eye exams, including specific diagnostic tests, are important for early detection of glaucoma. if diagnosed early enough, glaucoma can be properly managed to prevent major loss of vision.
Visual field testing, also known as perimetry, is a test that measures how sensitive a person's vision is. during a visual field test, you will look straight ahead at a small light or other target and will be asked to let the examiner know when you see a light flash off to the side in your peripheral vision. most visual field testing today is computerized. visual field testing usually needs to be repeated several times before the doctor can make a valid assessment.
