Computer automated electrooculography
Computers and Biomedical Research, 1972Abstract Clinical electrooculography requires a patient to track two points in the visual field separated by at least 30° visual angle in a horizontal plane while recording the concomitant change in potential from electrodes placed at the external canthi of the two eyes.

The electrooculogram (EOG) assesses the function of the retinal pigment epithelium (RPE), and also the interaction between the RPE and photoreceptors. This is done by noting the changes in the corneoretinal standing potential (the difference between the retina and electropositive cornea) during the dark-adapted and light-adapted states.

Electrooculography After Photodynamic Therapy
Documenta Ophthalmologica, 2005To evaluate the changes in electrooculography (EOG) after photodynamic therapy (PDT).Thirty-eight eyes of 38 patients (21 males, 17 females) with choroidal neovascularization secondary to age related macular degeneration were included in this study. Standart PDT with verteporfin was performed on each patient. Serial EOG recordings were performed before,

Electronystagmography and Electrooculography
Ophthalmologica, 1974Nystagmus is defined as involuntary, rhythmically repeated oscillations of one or both eyes. Qualitative and quantitative recording of these oscillations is called nystagmography. Electronystagmography (ENG) and electrooculography (EOG) are based on the recording of variations of the standing potential.

Electrooculography based font and punto analysis
2017 Medical Technologies National Congress (TIPTEKNO), 2017EOG is a measurement method that allows eye movements to be made into a testable signal based on the fact that the eyeball behaves like a battery. This method can measure the electrical potential of the pigmented layer of the eyeball in the retina through the instrument of electrodes placed around the eye. thus, eye movements get a quantifiable aspect.

Design of Wheelchair based on Electrooculography
2020 International Conference on Communication and Signal Processing (ICCSP), 2020The number of disable people are increasing at a rapid rate, disability to control limbs due to accidents or inherently are major cause of immobility. Immobility hinders daily activities and leads to social restrictions which isolate them from the rest. Various techniques like mechanized wheelchair have been designed for quadriplegic people.

Electrooculography as a Tool For Managing Application
2018 IEEE 20th International Conference on e-Health Networking, Applications and Services (Healthcom), 2018Eye movements are captured using the electrooculography method. This method uses an electrical potential which is able to measure thank to the eye movement and change a dipole of it. The aim was the design and realization of a light target made of LEDs, which illumination is controlled by movements of eyes.

Electrooculography by Wearable Graphene Textiles
IEEE Sensors Journal, 2018Study of eye movements and measurement of the resulting biopotentials, referred to as electrooculography (EOG), may find increasing use in applications within the domain of personalized medicine provided that the limitations of conventional “wet” electrodes are addressed.

Detection of myasthenia gravis using electrooculography signals
2016 38th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2016Myasthenia gravis (MG) is an autoimmune neuromuscular disorder resulting from skeletal muscle weakness and fatigue. An early common symptom is fatigable weakness of the extrinsic ocular muscles; if symptoms remain confined to the ocular muscles after a few years, this is classified as ocular myasthenia gravis (OMG). Diagnosis of MG when there are mild,

Eyes: Pupillography and Electrooculography
2000Abstract Investigators have claimed that various responses of the eyes can be used to determine many things, from interest in sexual feelings to the relative degree of processing occurring in the brain. Some of the more common areas of research have included relating the size of the pupil to arousal and examining eye movements in ...
