Electroretinograms and Normative Data
Electroretinography (ERG) is an important clinical tool that provides an objective quantitative measure of retinal function. Decreased a and b wave amplitudes and prolonged latencies correlate to reductions in retinal function that may be the result of toxicity, ischemic damage, or retinal dystrophy (Fishman et al. 2001, Ophthalmology monographs). Furthermore, since the different components of ...
متن کاملElectroretinograms from noncorneal electrodes.
A. lthough it has long been known that retinal action currents are present, the electroretinogram (ERG) has not become the subject of detailed investigation in the human until recent years. Before Riggs demonstrated that the response might be easily recorded from an electrode supported by a contact lens, no satisfactory method for continuous recording from the human was available. This techniqu...
متن کاملMultifocal electroretinograms in normal subjects.
Multifocal electroretinography (ERG), developed by Sutter in 1992, is a method of recording the spatial distribution of focal ERG in a short time period using multi-input stimulation. Using this technique, we can detect the spatial extent and severity of damage to the macula. In this study, we recorded multifocal ERGs from 20 eyes of 20 normal subjects and analyzed the topographical properties ...
متن کاملEfficacy and Variability of Aerosol Delivery from Portable DC-Powered
Method We compared the MiniElite and MicroElite (Philips/Respironics, Murrysville, PA), Traveler (DeVilbiss, Somerset, PA) and Trek S (Pari Respiratory Equipment, Midlothian, VA) using 200 uL of radiolabelled Tc as sodium pertechnetate in normal saline, added to either a 3 mL ampule of 2.5 mg albuterol and .25 mg in 2.0 mL of budesonide in separate tests. Particle size was measured by cascade i...
متن کاملRod multifocal electroretinograms in mice.
PURPOSE To test the feasibility of recording rod multifocal electroretinograms (ERGs) from the mouse eye. METHODS Multifocal ERGs were recorded from normal mice (C57BL/6J) using an array of equal-sized hexagons. Local stimuli were blue (W47A), and the number of blank frames between successive flashes at the same location was fixed at 14 (minimum 200 msec between flashes). Flash and surround i...
