Látótérteszt

Látótérteszt, meaning "visual field test" in Hungarian, refers to a medical examination used to assess a person's peripheral vision. This test measures the extent of the visual field, which is the entire area that can be seen when the eye is fixed in one position. It helps detect any blind spots or areas of reduced vision that may not be apparent during a routine eye exam.

There are several methods for conducting a látótérteszt. The most common type is confrontation visual field testing, where a healthcare professional moves a target, such as a finger or a small object, into the patient's peripheral vision from different directions. The patient is asked to indicate when they first see the target. Another method is automated perimetry, which uses a computer-controlled machine. In this test, the patient looks at a central point on a screen, and lights of varying brightness appear in different locations. The patient presses a button each time they see a light.

A látótérteszt is crucial for diagnosing and monitoring various eye conditions, including glaucoma, optic nerve damage, stroke, and neurological disorders. It can also identify vision loss caused by certain medications or injuries. Abnormal results may indicate a problem with the eye itself, the optic nerve, or the brain's visual pathways. Early detection through a látótérteszt can lead to timely treatment and potentially prevent further vision loss.
