Evidence of glaucoma - Glaucoma common tests used for diagnosis

There are a number of diagnoses that can opthalmalogist, and a series of tests used for glaucoma if you have an eye problem. The diagnosis of glaucoma is an important part of managing their condition and reporting changes in pressure may need to receive immediate medical attention. There are three glaucoma tests are used to see if you have the disease.




Test visual acuity




Visual acuity test is used to test his vision. This is commonly known as the Snellen chart, which most people when they visit the doctor for his yearly physical. If you are studying the Snellen chart, an ophthalmologist retinoscopes used to measure the angle of the eye.




The doctor will also want to check your near vision that you normally use for reading. It is common to be given a small card that contains the word lines that are progressively smaller. Over 40 who have difficulty reading small lines, because its hard to aim with a view to adapting them more difficult.




Another test for glaucoma is the slit lamp, to project beams of light in the bedroom of the eyes, allowing the physician to study the structure of the cornea, iris, lens, and d 'other parts of the eye. The doctor will have a magnificent view of the optical structure, and easily one of the drainage problems as a result of the symptoms of glaucoma.




Glaucoma test begins by placing the chin on the chin and head against a bar at that time, there is some light, while the doctor examines the eye. Structure of the cornea should be smooth and clear and free of any irregularities, and is very easy for a doctor in the opinion of glaucoma clouds.




A doctor will also examine the structure of their students to determine if you need a treatment of glaucoma. Students normally get in a bright room in May, but have an irregular shape due to a worsening of the inflammation of the iris or in cases of glaucoma.




Further evidence that glaucoma can be used is a measurement of intraocular pressure, which measures the amount of fluid pressure in the eye that is located inside the eye. Approximately 10 to 20 mm Hg is a normal level, but the range really varies depending on the individual.




It is common for a opthalmalogist periodically to measure the pressure inside the cavity of the eye to easily identify the symptoms of glaucoma.




The Goldmann tonometer is another type of glaucoma and the test device, which measures eye pressure by the pressure of a flat probe against the cornea, and then to the extent of the resistance to the process of flattening. An example of the cornea is a certain percentage and a lot of pressure just to give everything.




Glaucoma is a test device pneumotonometer most people who have some experience and it takes a small puff of air into the eye to measure pressure. The pneumotonometer is often a good measure of whether the pressure is too high, which opthalmalogist symptoms glaucoma can investigate further.




There is also a device called campimeter which can be used in the projections of glaucoma, but it is better to measure the damage if the glaucoma is under development. The campimeter consists of a rectangular matrix in which the patient is in a central location on the map, and are advised to focus on a point outside the circle. One issue is whether you'd still see the center points.




Glaucoma Campimeter test is about 80% accurate, but cheap in May ideal for early detection, even if you can not replace a professional visit to an ophthalmologist.




It is important to bear in mind when taking a test for glaucoma that natural body clock, and stress can increase or decrease the amount of intraocular pressure in the eye and changes also occur in May from week to week and months. Beta-blockers and hypertension medications can interfere with a glaucoma test, and doctors usually ask many questions about the drugs in his life before taking to provide a conclusive diagnosis of glaucoma.




There are also tonometers can be used at home, but should not be replaced by an examination of glaucoma by an ophthalmologist could play, taking a risk in your view is not a good opportunity to take. In case of doubt, this is a good idea simply to see a professional to care for your eyes checked for glaucoma symptoms.
