Electrooculography: Recording eye movements and analyzing the state of the retina

In today's world, medical diagnostics and research play an important role in understanding various aspects of the human body. One of the technologies used to study eye movements and the state of the retina is electrooculography. This electrical method allows you to record and analyze potential changes between electrodes attached to the skin at the inner and outer corners of the eye.

The operating principle of electrooculography is based on the use of eye movements that occur when looking in different directions or when tracking a moving object. When the eyes move, electrical potentials are generated that can be detected by electrodes on the skin. Measuring the potentials between the electrodes allows us to determine the direction and amplitude of eye movements.

The advantage of electrooculography is its non-harmfulness and the absence of the need for complex and expensive devices. The thin electrodes used in this method usually do not cause discomfort to the patient and can be easily attached to the skin in the eye area.

Electrooculography has found applications in a variety of fields, including medicine and scientific research. In medical practice, it can be used to diagnose and monitor certain diseases associated with disorders of the motor functions of the eye, such as nystagmus (involuntary rhythmic movements of the eye) and strabismus (discrepancy in the direction of gaze of both eyes). Electrooculography can also be useful in sleep studies and identifying sleep stages such as rapid eye movements (REM).

In addition, electrooculography can be used to assess the condition of the retina. Measuring the resting potential, that is, the potential between the electrodes in the absence of eye movements, can provide information about the electrical activity of the retina. This may be useful in detecting pathological changes associated with retinal diseases such as retinopathy and glaucoma.

However, it should be noted that electrooculography has its limitations. For example, it is not accurate enough to measure fine eye movements, and its usefulness is limited in environments with strong electromagnetic interference. Also, the results of electrooculography may depend on the position of the electrodes on the skin and other external factors.

In conclusion, electrooculography is a useful tool for recording eye movements and analyzing retinal health. It has applications in both medical diagnostics and scientific research, helping to understand various aspects of eye function. Despite some limitations, this technique remains a valuable research tool in advancing knowledge about eye movements and retinal diseases.

Electrooculography is an electrical method for recording eye movements that is widely used in clinical practice to diagnose various diseases of the eye and neuromuscular system.

The essence of the method is to attach thin electrodes to the skin at the inner and outer corners of the eye. During eye movement, a change in potential occurs between these electrodes, which is recorded and analyzed by special equipment.

Electrooculography allows you to measure both the speed of eye movements and their amplitude. This allows you to determine the presence and degree of disturbances in the functioning of the eye muscles, as well as assess the functional state of the retina.

In addition, measuring the resting potential allows one to judge the condition of the retina. This is especially important for diagnosing diseases associated with poor circulation in the eyeball.

There are various modifications of electrooculography that make it possible to record not only horizontal and vertical eye movements, but also their rotation. In addition, electrooculography can be used to study the eye's response to various stimuli, such as light pulses or sound signals.

Electrooculography is a non-invasive and safe diagnostic method that can be used both in clinical practice and in scientific research. Its use provides valuable information about the functioning of the eyes and neuromuscular system, which helps in the diagnosis and treatment of various diseases.

Electrooculology (EOG) is a method of electrographic study of the biopotentials of the sleepy, waking, and functional states of the human brain. The EEG method is an electrophysiological study of the brain aimed at determining the spectral composition of the electrical potentials of the cerebral cortex

Electrooculography is the study of electrical processes occurring in the human visual system to assess the state of the organ of vision. The organs affected by these processes include the neuromuscular system of the eye, the orbit, the lens and other structures.

EOG results provide the doctor with important information about the functioning of the nervous system, autonomic regulation processes and the internal balance of the human body as a whole. Thus, EOG is very important in the practical medicine of a neurologist, otorhinolaryngologist, and endocrinologist. The method is often used by specialists in other fields of medicine and therapeutic areas. Indications for EO diagnostics are chronic headaches for unknown reasons, frequent attacks of epilepsy with the absence of noticeable background brain activity, mental illness, etc.
