ELECTROOCULOGRAPHY SEMINAR REPORT PDF
Electrooculography is a technique for measuring the resting and action potential of the retina. The resulting signal is called the electrooculogram. Usually, pairs. Electrooculography, an introduction Electrooculography is the medical terminology for a method used to calculate eye movement, specifically.

Electro-occulography is widely used in ophthalmic research and clinical laboratories because it provides the method for recording with full range of eye movements.
For other uses, see EOG disambiguation. As it can be seen from the above figure, four to five electrodes are required for the detection of the EOG signals. December Learn how and when to remove this template message.
Please help us clarify the section. Electrooculography, an introduction Electrooculography is the medical terminology for a method used to calculate eye movement, specifically the movement of the retina. Eoectrooculography material may be challenged and removed. Because this biological signal ssminar proportional to the rotational angle of eye this technique permits a wide range of rotational angles to be recorded, allows documenting of eye movements when the eyelids are closed and unable the recording in the dark places.
Electrooculography Seminar Report, Abstract
The derivation of the EOG is achieved placing two electrodes on the outer side of the eyes to detect horizontal movement and another pair above and below the eye to detect vertical movement. Electromyography Facial electromyography Nerve conduction study. The placement of the electrodes is up and down or right and left. The advantage of EOG eye gaze interface is its simple configuration: This technology is based on the principle of recording the polarization potential or corneal-retinal repport CRPwhich is the resting potential between the cornea and the retina.
Please refer to our Seminar PPT preparation guide for a better quality seminar.
The doctor will then measure the center position and this difference is the measurement of the position of the eye. Are you interested in this topic. During dark seminraresting potential decreases slightly and reaches a minimum “dark trough” after several minutes.
The patient is asked to switch eye position repeatedly between two points alternating looking from center to the left and from center to the right.
Electro-occulograph can be used in ophthalmology for diagnosis and prognosis of several eye ailments. It is now accepted that the generated electrical potential arises due to the permanent seinar difference 10 to 30mV that exists between the cornea and ocular fundus. Primary applications are in ophthalmological diagnosis and in recording eye movements. One more interesting factor regarding the ECG signals are that, it does not interfere with the EOG signals, because when EOG is measured using precision electrodes, seminwr as ECG is generated repirt the heart it does not get detected by the electrodes placed near the eye.
In other projects Wikimedia Commons. Electrodiagnosis Eye procedures Electrophysiology Neurophysiology Neurotechnology. Positive or negative pulses will be generated when the eyes rolling upward or downward. Then mail to us immediately to get the full report.
This potential is commonl y known as electrooculogram. Views Read Edit View history. Due to the movement of the retina, there will be a difference in the electrodes. November Learn how and when to remove this template message.

Not to be confused with other types of electrography. Assuming that the resting potential is constant, the recorded potential is a measure of the eye’s position. Please help improve it or discuss these issues on the talk page.
