ELECTROOCULOGRAMS Meaning and
Definition
-
Electrooculography, abbreviated as EOG, refers to the measurement and recording of the electrical activity generated by the movement of the eye muscles. The primary purpose of electrooculography is to assess and analyze the eye movements and determine their patterns or characteristics. The instrument used to record these electrical potentials is called an electrooculograph.
Electrooculograms are obtained by placing electrodes on various locations around the eyes, specifically on the outer canthi and inner canthi, to detect the eye movements effectively. The outer canthi electrodes measure the potential difference between the front and back of the eye, while the inner canthi electrodes record the vertical eye movements. This differential measurement allows for the differentiation and measurement of the horizontal and vertical eye movements.
The recorded electrooculograms provide valuable information about eye movements, such as saccades, smooth pursuits, and nystagmus, among others. These eye movements can be indicative of various neurological and ophthalmological conditions, such as ocular motor disorders, vestibular dysfunction, and visual impairments. By analyzing the electrooculograms, clinicians and researchers can evaluate and diagnose these conditions, monitor the effectiveness of treatments or interventions, and understand the eye movement patterns during different tasks or activities.
In summary, an electrooculogram is a graphical representation of the electrical activity generated by the eye muscles when the eyes move. It is an important diagnostic tool used in neurology and ophthalmology to evaluate patterns of eye movements and identify abnormalities related to these movements.

Etymology of ELECTROOCULOGRAMS
The word "Electrooculograms" is derived from combining three different components: "electro-", "oculo-", and "-grams".
"Electro-" is a prefix derived from the Greek word "ēlektron", meaning "amber" or "electricity". It is commonly used in scientific and medical terms to indicate an electrical or electronic aspect or process.
"Oculo-" is a prefix derived from the Latin word "oculus", meaning "eye". It is used in medical terms related to the eye or vision.
"-grams" is a suffix derived from the Greek word "gramma", meaning "something written" or "a record". It is commonly used to refer to a chart, a graphic representation, or a written recording of something.
