Glaucoma Test | Glaucoma Drugs

The visual field is quite simply the angle at which a normal person can see without moving their head, and the most important part involves the peripheral nerves, which let people see out of the corners of the rye.

The retina makes peripheral vision possible as it is composed of blood vessels and nerves which become excited when light hits them, but many people suffering from glaucoma symptoms have defective peripheral vision, and they may simply miss objects or people that a normal person would see.

The reason that k affects ones peripheral vision is because there are fewer cells in the periphery of the eyes, and as sight begins to decrease, closing in on the central areas of the eyes, the glaucoma prognosis gets more and more severe.

The campimeter is a common eye instrument that is used in order to measure a defective visual field, and there are three main instruments that an eye doctor will use as a glaucoma test. Together these three instruments can form a picture of the health of your eyes, although automated instruments are now increasingly the preferred option to use as a glaucoma test.

Of course, an automated glaucoma testing system may aggravate or upset some people, so these methods can be most suitable. The first glaucoma test uses spots of light and when you see these beams you have to press a buzzer, and you will do this for about 20 to 30 minutes. When tracking the light you are not allowed to move your eyes and must keep them perfectly still, and using this method an eye doctor can monitor your peripheral vision.

The visual field analyzer created by Dr. Goldmann also uses spots of light in order to check peripheral vision, and this glaucoma test is operated manually by a physician, as opposed to having automated sequence.

Static perimetry is another type of glaucoma testing method that involves using a very low light that stays in one position with the brightness constantly increased until you can see it. This glaucoma test light will usually start out as a very tiny pinprick gradually going in size, and you have to press the hand buzzer when you notice the light coming into focus.

The Humphrey and the Octopus are two common glaucoma testing equipment names, and a eye doctor may utilize one or both of them, and the glaucoma test itself can take a long time which may result in eye fatigue.

Some disadvantages of visual field testing is that the glaucoma test itself can cause anxiety and it also takes quite a long time. Anxious people will also make a number of errors by pressing the buzzer too soon, so it is a good idea to be calm when you go out to receive your glaucoma testing.

Most eye researchers believe that a proper test could take around 40 hours, but of course no one would take such a ridiculous glaucoma test, so the doctor has to make do with around 1/2 hour to an hour. Cataracts and constricted pupils can also have an affect on these glaucoma testing methods, and a natural persons reaction time may also affect how they score on the glaucoma exam.

Static perimetry is probably the most useful manual glaucoma testing method today, but there still problems of timing in automated tests that should make the process of identifying aqueous fluid buildup and glaucoma symptoms much easier to identify over time.

You show let your eye doctor know of any particular health defects that you may have as the glaucoma tests are easily confounded by a number of variables. It is also important to remember that the visual field for most people will decrease with age. Myopia can create further problems and the glaucoma test itself may also diagnose other eye conditions, such as cataracts.

Doctors are seeking better and better tools over time, so hopefully automated glaucoma testing methods will eventually be developed that will take no longer than five minutes for a conclusive glaucoma diagnosis, but for now it is mostly a process that a doctor will undertake which will consist of a measure of intraocular pressure, a study of the optic nerve, and the visual field test.

Glaucoma is not a static illness and even with medication an individual needs to have their eyes constantly studied and this score will change over time, with your ophthalmologist recommending routine glaucomas examinations.

Of course, even with glaucoma treatment, usually a certain amount of peripheral vision will be lost, so the sooner you receive treatment for your glaucoma symptoms the less risk you’ll have a vision loss and the more vision that will return once the condition is treated.
