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...
متن کاملElectroretinograms 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 کاملKDOQI Clinical Practice Guideline for Diabetes and CKD: 2012 Update.
The 2012 update of the Kidney Disease Outcomes Quality Initiative (KDOQI) Clinical Practice Guideline for Diabetes and Chronic Kidney Disease (CKD) is intended to assist the practitioner caring for patients with diabetes and CKD. Substantial high-quality new evidence has emerged since the original 2007 KDOQI guideline that could significantly change recommendations for clinical practice. As suc...
متن کاملPattern electroretinography in age-related macular degeneration.
OBJECTIVE To determine whether prolonged vascular endothelial growth factor inhibition is toxic to the retina by using pattern electroretinographic imaging in participants with neovascular age-related macular degeneration (AMD). METHODS We performed a prospective, single-arm clinical trial of 17 eyes in 17 treatment-naive participants with subfoveal choroidal neovascularization from AMD. On-l...
متن کاملClinical electroretinography for short wavelength sensitive cones.
We measured electroretinograms (ERGs) for the isolated short-wavelength-sensitive (SWS) cones using a substitution technique. The stimulus was a 5 Hz alternation of 460 nm and 565 nm or 490 nm and 565 nm light of equivalent photopic luminous efficiency. We used a 571 nm narrow-band adaptation field of 7000 td to improve SWS cone isolation and to suppress rod activity. The resulting SWS cone ERG...
