Electrooculography is a technique for measuring the resting and action potential of the retina. The resulting signal is called the electrooculogram. Usually, pairs.

When the doctor asks the patient to see one electrode, the portion of the retina facing that position is the plus side and the portion away from that electrode is the minus side.

Electrodiagnosis Eye procedures Electrophysiology Neurophysiology Neurotechnology. This page was last edited on 8 Novemberat We do not prepare a PPT for your seminar, how ever we can help you providing ideas, please do your own research on the topic and prepare a seminar PPT Electrooculography. Electrooculography, an introduction Electrooculography is the medical terminology for a method used to calculate eye movement, specifically the movement of the retina. When the eyes are stationary or when the eyes are looking straight ahead, there is no considerable change in potential and the amplitude of signal obtained is approximately zero.
This difference is due to the large presence of electrically active nerves in the retina compared to the front of the eye. The important factor regarding the EOG signal is that it does not fall in the amplitude or frequency range of the EMG signal ,thus during the process of measurement of the EOG signals ,the head or other parts of the body can be moved ,as these muscular activities will not interfere with the EOG signals and can be filtered easily.
Download your Reports for Electrooculography Eye movement measurement has long been an area of intense interest for researchers in a multitude of fields ranging from medicine to psychology and from advertising to computing. This method is dependent on a terminology called as Resting Potential.
In practice, the measurement is similar to eye movement recordings see above. December Learn how and when to remove this template message. To measure, the repprt and electoroculography points of the retina, Doctors make the use of electrodes.
Electrooculography Seminar Report, Abstract
In other projects Wikimedia Commons. The ratio of the voltages i. Due to the movement of the retina, there will be a difference in the electrodes. Please help improve this section by adding citations electrooculographt reliable sources.
Electrooculography Seminar Report, Abstract
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, and as ECG is generated by the heart it does not get detected by the electrodes placed near the eye. To measure eye movement, pairs of electrodes are typically placed either above and below the eye or to the left and right of the eye.
EOG is a very small electrical potential that can electrooculogrraphy detected using electrodes. You should do your own research additional to this information before presenting your seminar. This section does not cite any sources. The design and development of eye movement measurement and tracking systems most frequently arises during the course of inter-disciplinary research projects.
Electro-occulography is recording technique that allows the standing potential between the ellectrooculography and the posterior pole of the eye tube recorded.
Electroocuography help us clarify the section. Resting potential refers to the difference between two points in the retina from its center position.
In cases of extensive brain damage, where the person is unable to communicate verbally or physically, doctors can use this method to track brain activity. An electrical field is set up in the tissues surrounding the eye and the rotation of the eye causes corresponding rotation of field vector.

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. The electrooculogram EOG is the electrical signal produced by the potential difference between the retina and the cornea of the eye.
The placement of the electrodes is up and down or right and left. The EOG is used to assess the function of the pigment epithelium.
The doctor electeooculography then measure the center position and this difference is the measurement of the position of the eye.

Unlike the electroretinogramthe EOG does not measure response to individual visual stimuli. Scientists use this method to help disabled individuals control wheelchairs, help them operate computers etc.
Hello Haritha, Welcome to Collegelib!
Blepharoplasty East Asian blepharoplasty Epicanthoplasty Tarsorrhaphy. When se,inar eyes are made to move upwards, then there results an action potential, which when measured will give a value of As it can be seen from the above figure, four to five electrodes are required for the detection of the EOG signals.
