Glaucoma test - Verification of the visual field of the symptoms of glaucoma

The visual field is simply the angle from which a normal person can see without moving his head, and the most important part on the peripheral nerves, which allows people to see over the rye.




The retina is a possibility that the peripheral vision, which is composed of blood vessels and nerves that are excited when the light hits, but many people with glaucoma symptoms have a faulty device, and simply lost objects or persons in May that the normal person.




The reason why chronic glaucoma affects peripheral vision is, because there are fewer cells in the periphery of the eye, and the view begins to fall, closing the central zone of the eye, glaucoma, the prognosis becomes increasingly serious.




Campimeter the eye is an instrument used to measure a visual field defect, and there are three main tools of a doctor used as a test for glaucoma. Together, these three instruments can provide a picture of the health of the eyes, even if automated tools are increasingly the preferred choice for use as a test for glaucoma.




Of course, an automated test system or aggravate glaucoma May upset some people, these methods may be more appropriate. The first test for glaucoma using the points of light, when you see these beams must press a buzzer, and does so for about 20 to 30 minutes. Followed when the light is not allowed to move the eyes, and must remain perfectly still, and with this method, the doctor may check your peripheral vision.




The visual field analyzer developed by Dr. Goldmann also used to check signal peripheral vision, glaucoma test, and manually operated by a doctor, instead of having automated sequences.




Static perimetry is another type of glaucoma that the test method involves the use of very little light left in a constant position to increase the brightness until you can see. This view of the glaucoma test usually by a very small peak in size gradually, and you must press the buzzer to hand when you notice the light coming into the house.




The Humphrey and Octopus glaucoma are two names for test equipment and a doctor in May to use one or two cases, the glaucoma and the test itself may take a long time in May, that eye fatigue.




Some drawbacks of the visual field test is that the glaucoma test itself can cause anxiety and it takes some time. Anxious people also some errors in pressing the buzzer too soon, so it's a good idea to be calm when you receive your glaucoma testing.




Most researchers believe that the eyes can take a test about 40 hours, but of course nobody can make such ridiculous glaucoma test, the doctor has to do with about 1 / 2 hour to an hour. Constriction of the waterfall and students can also have an impact on the glaucoma in these methods, people and a response time can also affect how the score on the examination of glaucoma.




Perimetry is probably the most useful manual testing method glaucoma today, but there are still problems in the timing of automated tests that should make the identification process and the accumulation of liquid water glaucoma symptoms much easier to identify over time.




Showing that his personal physician, the health of any defects that the tests in May as glaucoma are easily confused by a number of variables. It is also important to remember that the field of view most people diminishes with age. Myopia can create new problems of glaucoma and the test itself May also diagnose other eye diseases such as cataracts.




Doctors are looking for better tools and better with time, so I hope glaucoma automated test methods will be developed, taking no more than five minutes to complete the diagnosis of glaucoma, but for the moment it is mainly a process that will a physician that includes a measure of intraocular pressure, a study of the optic nerve and visual field test.




Glaucoma is a disease with drugs and even an individual must have their eyes constantly studied, and the score will change over time, with your eye doctor to recommend routine testing of glaucoma.




Of course, even with the treatment of glaucoma, usually a degree of peripheral vision is lost, so before receiving treatment for glaucoma, the symptoms you have less risk of loss of vision and the vision that Most will be back once the condition is.
