Validation of a new fiber electrode prototype for clinical electroretinography.

PURPOSE To validate a new fiber electrode prototype for clinical electroretinography (ERG). METHODS A recently developed prototype of a disposable reference-coupled fiber electrode (patent pending Brazilian Institute of Industrial Property # PI0602186-7), including one fiber for corneal signals and a second fiber acting as reference was tested in a group of 20 healthy volunteers (17-31 years;...

Electroretinography in dogs using a fiber electrode prototype

We compared two electroretinography (ERG) electrodes in dogs using ERG standards of the International Society for Clinical Electrophysiology of Vision (ISCEV). Ten healthy Yorkshire terrier dogs (mean age, 2.80 ± 1.42 years; 6 females) weighing 5.20 ± 1.56 kg were evaluated using an ERG system for veterinary use. Dark- and light-adapted ERG responses were recorded using an ERG-Jet electrode and...

A gold foil electrode: extending the horizons for clinical electroretinography.

A gold foil ERG electrode is described. The device is inexpensive and simple to fabricate. Since it is hooked over the lower lid and makes minimal touch contact with the inferior limbal area, it can be used in circumstances which require prolonged testing of retinal function or in eyes with corneal pathology. Because the optics of the eye are not compromised, it is possible, with the use of app...

Electrode comparison in pattern electroretinography.

In recent years, there has been great interest in recording the pattern electroretinogram (PERG) in glaucomatous and diabetic populations. The Dawson, Trick, and Litzkow thread electrode (DTLTE) and the gold foil electrode (GFE), commonly used for recording PERGs, were compared for variations in amplitude of response, test-retest variability, and patient comfort. Two study centers collected dat...

A New Clip Electrode for Clinical Electrocardiography.

IN every cardiac emergency the application of the electrodes for taking electrocardio-grams should require the least possible time. Time saved may be a life saved. The prompt establishment of the presence of and the exact type of cardiac mechanism disorder by electro-cardiographic tracings, is a prerequisite to effective therapy. The electrocardiogram must often be taken while external cardiac ...
