Webvision-EOG-Creel | The Electro-oculogram: Clinical Applications | The electrooculogram measures the potential that exists between the cornea and Bruch's membrane at the back of the eye. The potential produces a dipole field with the cornea approximately 5 millivolts positive compared to the back of the eye, in a normally illuminated room. Although the origin of th... | Electro-oculogram |

Webvision-ERG-Creel | The Electroretinogram and Electro-oculogram: Clinical Applications | The global or full-field electroretinogram (ERG) is a mass electrical response of the retina to photic stimulation. The ERG is a test used worldwide to assess the status of the retina in eye diseases in human patients and in laboratory animals used as models of retinal disease. | Electroretinogram; Electro-oculogram |

Webvision-VEP-Creel.pdf | Visually Evoked Potentials | Detailed explanation of visually evoked potentials. The terms visually evoked potential (VEP), visually evoked response (VER) and visually evoked cortical potential (VECP) are equivalent. They refer to electrical potentials, initiated by brief visual stimuli, which are recorded from the scalp overl... | Visually Evoked Potentials |

Webvision-mfERG-Creel | The Multifocal Electroretinogram: Clinical Applications | The most important development in ERGs is the multifocal ERG (mfERG). Erich Sutter adapted the mathematical sequences called binary m-sequences creating a program that can extract hundreds of focal ERGs from a single electrical signal. This system allows assessment of ERG activity in small areas of ... | Multifocal Electroretinogram |

cochet-bonnet_esthesiometer_exam | Cochet-Bonnet Esthesiometer (similar to Von Frey Hair) Exam | The Cochet-Bonnet esthesiometer , similar to Von Frey Hair testing, has been used in studies to quantify sensory changes in the trigeminal system, especially the cornea. The device uses a thin fiber to test sensation. The shorter the fiber, the more sensation is felt. The monofilament is applied per... | Exam, Cochet-Bonnet Esthesiometer |

coloboma.jpg | Bilateral Iris Colobomas | Coloboma literally means a "gap"-and can be used to describe any fissure, hole, or gap in the eye. The term most often is used to refer to a congenital gap in the disc, retina, the choroid, and the iris. Colobomas occur because the embryonic fissure fails to fuse. Since the fissure closure begins in... | Congenital Pupillary Abnormalities; Pupil; Etiology, Pupil Disorders; Pathology, Pupil Disorders; Correctopia |

glaucoma notching | Notching of the Neuro-retinal Rim | The neuro-retinal rim becomes thinner; in particular the rim superotemporally and inferortemporally may develop a notch which is usually superior or inferior and rarely nasal or temporal. These notches are believed to be due to focal ischemic damage to the neuro-retinal rim. Glaucoma with Notching a... | Glaucoma |
