“…Gender differences in ERG b-wave amplitude have been noted by several investigators, with amplitude being slightly smaller in males [10,11]. This has been attributed to the greater axial length in comparison with females.…”

“…The effect of age on ERG parameters has been well documented [10]. Although the precise factors causing the decrease in ERG amplitude in the elderly are not well understood, it is likely that preretinal media changes, a reduction of photopigmental density, and increased retinal neurodegeneration could account for such age-related amplitude reduction [5].…”

Purpose: The aim of this study is to present the largest normative database using multifocal electroretinography (mfERG) in the context of a multicenter clinical trial. Methods: This investigational study included 156 eyes from 78 Caucasian subjects aged 45-70 years without known ophthalmic disease or diabetes mellitus; the subjects were recruited from 11 clinical sites in the setting of the EUROCONDOR project. Standardized mfERG acquisition (103 hexagons per eye) was established based on the International Society of Clinical Electrophysiology in Vision. At least one technician per site received both specialized training and certification. The main variables that could have influenced the results were considered in the analyses. Results: The normative database was based on 111 eyes. The overall mean P1-implicit time (IT) was 33.94 ± 1.70 ms, and the mean P1 amplitude was 30.58 ± 5.20 nV/deg². Age and gender were independently related to predictors of P1-IT but not of P1 amplitude. The responses that were averaged for the 6 rings showed a longer P1-IT time in the fovea, decreasing progressively to the parafovea and perifovea. By contrast, P1 amplitude values sharply decreased with retinal eccentricity. Conclusions: This normative database can be used as a comparative index of expected normal values in the clinical setting and for examining the effect of studies testing neuroprotective agents.

Por se tratar de exame objetivo e pouco invasivo, tem grande utilidade na avaliação pré-operatória de pacientes com catarata madura, nos quais não é possível avaliar o fundo do olho (GRANITZ, 1994).…”

“…Essa resposta é complexa, pois é o resultado do conjunto da atividade de milhões de células retinianas (BIRCH, 1989;BIRCH & ANDERSON, 1992;DANTAS, 1995;YANASE & OGAWA, 1997). A sua importância se dá por tratar-se de meio diagnóstico objetivo (TZEKOV & ARDEN, 1999), não invasivo (SAFATLE et al, 2005) e capaz de avaliar a função retiniana, detectando precocemente lesões nas suas camadas mais externas (MARMOR & ZRENNER, 1998;KOMAROMY et al, 1998a).…”

Electroretinogram (ERG) is an objective and noninvasive diagnostic tool for the evaluation of retinal function, capable to detect early, lesions of the outermost layers in several species of animals. One of its main indications is to evaluate pre-surgical patients for cataract surgery. The determination of normal ERG values is essential if the aim is, by measuring the values; aid the diagnosis of retinal degeneration, despite of the presence of media opacity (cataract
