Electrooculography After Photodynamic Therapy

Documenta Ophthalmologica, 2005
To 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, 1974
Nystagmus 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), 2017
EOG 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), 2020
The 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), 2018
Eye 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.

Detection of myasthenia gravis using electrooculography signals

2016 38th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2016
Myasthenia 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

2000
Abstract 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 ...

Low-Cost Wireless Electrooculography Speller

2018 IEEE International Conference on Systems, Man, and Cybernetics (SMC), 2018
While communication is an innate ability to most of us, individuals with severe motor disability such as amyotrophic lateral sclerosis (ALS) have difficulty in daily communication. Nowadays, with the help of human-computer interface (HCI), they can communicate using bio-signal which can be measured from the human body and monitored. Electrooculography (

Multiclass electrooculography using common spatial pattern

2012 35th International Conference on Telecommunications and Signal Processing (TSP), 2012
In this paper we apply common spatial pattern (CSP) to the classification of electrooculography (EOG) signals with four distinct classes, namely, eye blinks (EB), eye rotation clockwise (ERC), vertical eye movement (VEM) and horizontal eye movement (HEM). We first describe the CSP and Linear Discriminant Analysis (LDA) algorithms with two classes.
