Electroretinography in dogs: a review
Electroretinography (ERG) in the form of full-field, flash ERG is the most commonly used technique in veterinary ophthalmology for diagnosing the functioning of the outer retina. Under light stimulation spatially distributed different cell types within the retina produce time-varying electric responses. These are recorded in the form of ERG traces consisting of a series of positive and negative...
متن کاملElectroretinography 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...
متن کاملElectroretinography in Dogs and Cats. Part II. Technique, Interpretation, and Indications
Electroretinography, a technique that objectively assesses the function of the retina, is used to evaluate the progression of retinal disorders. Part I of this two-part presentation discussed the morphologic and physiologic characteristics of the retina. The information presented in Part II can help practitioners determine when an electroretinogram (ERG) is recommended. In addition to the stand...
متن کاملThe determination of dark adaptation time using electroretinography in conscious Miniature Schnauzer dogs
The optimal dark adaptation time of electroretinograms (ERG's) performed on conscious dogs were determined using a commercially available ERG unit with a contact lens electrode and a built-in light source (LED-electrode). The ERG recordings were performed on nine healthy Miniature Schnauzer dogs. The bilateral ERG's at seven different dark adaptation times at an intensity of 2.5 cd.s/m(2) was p...
متن کاملComparison of two electroretinography systems used in dogs: the HMsERG and the RETIport.
The purpose of the study was to compare two different electroretinography (ERG) instruments used on the same animal in a laboratory setting. Retinal function in both eyes of 12 healthy miniature schnauzers was evaluated under general anesthesia. Scotopic and photopic ERGs were recorded by the HMsERG and the RETIport using the Dog Standard Protocol recommended by the European College of Veterina...
