As you read this text, how much do you notice from the lateral parts of your computer or mobile phone?

A visual field actually means the area that your eye can notice while focusing on a specific focal point (up, down and on both sides of the point where the eyes are focused). The vision is typically the sharpest in the middle of the field of view.

The visual field test determines what your vision is in both eyes and whether there is a loss of vision that has occurred over time.

The visual field is useful for diagnosing and monitoring the following eye conditions:

• glaucoma;
• macular degeneration;
• macular edema;
• diabetic retinopathy;
• diabetic maculopathy;
• optic glioma;
• swelling of the optic nerve (ocular neuritis);
• lower lid (ptosis).

The visual field is also used to diagnose:

• brain tumor;
• multiple sclerosis;
• stroke;
• temporal arteritis;
• conditions of the central nervous system;
• pituitary disorders;
• high blood pressure;
• the effect on the central retina of certain drugs.

In our clinic, an automated static perimeter test of the visual field is performed.

It is a device which purpose is to examine your field of vision, i.e. it creates a map of what you can and cannot see.

An optometrist / nurse is with you during the test.

You sit in front of the device which looks like a round deep plate and your head is placed on a support for stability.

The untested eye is covered with a patch. It is necessary to look at the central part of the apparatus during the test. Small, dim lights will start to appear in different places and you need to press the button every time you see a light. The test tracks which lights you have not seen.

The lights do not move through the screen but shine at different intensities in different locations. This test is therefore static.

Some lights are stronger and easier to notice but some are very faint and barely noticeable. These dim lights that you can barely see determine your lower threshold for light sensitivity. This parameter is very important for the diagnosis of many diseases of both the retina and the optic nerve but also through this diagnostic method, diseases and conditions of the brain are detected.

In patients who find it difficult to concentrate for 15 to 30 minutes.

The visual field test is radiation-free imaging.

There is a possibility to pay in installments without interest and additional costs.
