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.

The doctor will then measure the center position and this difference is the measurement of the position of the eye. EOG is a very small electrical potential that can be detected using electrodes. This method is dependent on a terminology called as Resting Potential. When light is switched on, a substantial increase of the resting potential occurs “light peak”which drops off after a few teport when the retina adapts to the light.

Are you interested in any semunar of this Seminar, Project Topics. 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. Many experiments show that the corneal part is a positive pole and the retina part is a negative pole in the eyeball. Electrooculography was used by Robert Zemeckis and Jerome Chenthe visual effects supervisor seminzr the movie Beowulfto enhance the performance capture by correctly animating the eye movements of the actors.

The resulting signal is called the electrooculogram. The typical EOG waveforms generated by eye movements are shown in Fig 3. Electrooculography Published on Nov 23, semiinar During dark adaptationresting potential decreases slightly and reaches a minimum “dark trough” after several minutes.

Eye movements are the most frequent of all human movements. Assuming that the resting potential is constant, the recorded potential is a measure of the eye’s position.

From Wikipedia, the free encyclopedia. November Learn how and when to remove this template message. Despite the recent technological improvements, eye trackers remain very much a high cost research and academic tool requiring specially trained personnel to set-up and operate the systems. Positive or negative pulses will be generated when the eyes rolling upward or downward.

By using this site, you agree to the Terms of Use and Privacy Policy. To measure eye movement, pairs of electrodes are typically placed either above and below semina eye or to the left and right of the eye. Electrooculography EOG is a technique for measuring the corneo-retinal standing potential that exists between the front and the back of the human eye. Since these positions are constant, a change in the recorded eleftrooculography originates from a change in the resting potential. For other uses, see EOG disambiguation.

Enucleation of the eye. Then mail to us immediately to get the full report. In the process of detection, the electrodes act electrooculograpyy a transducer converting the ion current obtained at the skin to electron current. This section does not cite any sources.

For this reason, it is possible to detect eye movement with the appropriate placement of electrodes on the skin surrounding the eyes. Electro-occulography is widely repotr in ophthalmic research and clinical laboratories because it provides the method for recording with full range of eye movements. Phacoemulsification Cataract surgery Capsulorhexis. In other projects Wikimedia Commons. The ratio of the voltages i.

The EOG is one of the very few methods of recording eye movements that does not require a direct attachment to the eye itself.
