Scotometry

Scotometry is a method of studying visual function that is used to determine the presence and characteristics of scotomas - areas of the visual field in which vision is absent or reduced.

Scotomas can occur due to various diseases of the eye or brain, such as glaucoma, degenerative changes in the retina, or brain tumors. They can be temporary or permanent and cause varying degrees of visual impairment.

Scotometry is carried out using special devices called scotometers. The patient is asked to look at a fixed point in the center of the screen, while the specialist gradually reduces the light intensity and moves the light spot across the screen. In this case, the patient must indicate the moment when the spot ceased to be visible. Based on the results of the study, a map of scotomas is formed - a graphic representation of areas of reduced or absent visual sensitivity.

Scotometry is an important method for diagnosing eye and neurological diseases, and also allows assessing the effectiveness of treatment and predicting the development of diseases. Currently, there are various types of scotometers that allow research to be carried out with high accuracy and efficiency.

In conclusion, scotometry is an important method for studying visual function, which allows us to determine the presence and characteristics of scotomas, which helps in the diagnosis and treatment of various diseases. Scotometricians play an important role in eye health and vision research.

Scotometry is a medical term that describes a condition where the patient's eye is unable to discern small details in close objects. This problem occurs due to a malfunction of the retina, which is responsible for vision in the dark and in bright light.

Scotometry is used to determine the threshold at which a person could not distinguish objects at some distance from him. This will help determine the degree of visual impairment and, therefore, prescribe adequate treatment. It is important to note that scotometric tests are the only reliable method for measuring visual acuity in uncorrected eyes. They do not replace the diagnosis and treatment of ophthalmologists and can only be carried out by specialists.

However, sometimes, scotoma can also be the result of problems with the brain, such as tumors or stroke. In this case, the scotometric test may not indicate the patient's exact condition. Depending on the type of problem, your doctor may suggest other diagnostic and treatment methods.
