Retina in rheumatic diseases: standard full field and multifocal electroretinography in hydroxychloroquine retinal dysfunction.
BACKGROUND The purpose of this study was to evaluate and compare full-field electroretinography (ERG) and multifocal electroretinography (mfERG) results in detecting retinal dysfunction in a large number of asymptomatic patients treated with hydroxychloroquine (Hy). METHODS Fifty eyes in 50 patients with rheumatic diseases who had been using Hy for a period of time ranging from 30 months to 1...
متن کاملFull-Field versus Multifocal Electroretinography
Full field electroretinography (ffERG) or conventional electroretinography represents the summed electrical response of the entire retina evoked by a flash light from an arc bowl (Ganzfeld stimulus bow) scattered in the eye through a dilated pupil. Clinical applications of ffERG were initiated in the 1940s, therefore clinical and basic studies on ERG date back to several decades. In 1989, the I...
متن کاملNormal Values of Standard Full Field Electroretinography in Healthy Subjects in Northern Iran
Background: Electroretinography (ERG) is known as a diagnostic test for evaluating the performance of different layers of the retina. Its normal values maybe different in different populations. Objectives: Determining the normal values of ERG parameters in patients presenting to an ophthalmologic center in Guilan in northern Iran. Materials and Methods: Fifty-five people presenting to a teach...

PURPOSE To determine measurement variability of N1P1 amplitudes and the R1/R2 ratio in normal subjects and hydroxychloroquine users without retinopathy. DESIGN Retrospective, observational study. SUBJECTS Normal subjects (n=21) and 44 patients taking hydroxychloroquine (n=44) without retinopathy. METHODS Multifocal electroretinography (mfERG) was performed twice in one session in the 21 n...
