AIM: This study was designed to answer the question of whether multifocal steady-state pattern-reversal electroretinography (ERG) is capable of detecting @entity227 . METHOD: Sixteen @entity1 (28 eyes) and ten normal subjects (20 eyes) were examined. Multifocal pattern ERGs were recorded with the RETIscan system and DTL electrodes. We stimulated with a steady-state checkerboard pattern reversal (three reversals during 171 ms sweep length, congruent with 17.5 reversals/s). The multifocal pattern ERG amplitudes were evaluated using discrete Fourier transformation (DFT) across three reversals. In cases of advanced @entity726 , the DFT-calculated amplitudes were combined in hemispheres and checked for correlations with corresponding @entity227 . In all binocularly examined @entity1 , side comparisons ("worse" eye vs "better" eye), and interindividual comparisons ( @entity726 vs normal) were carried out. RESULTS: In interindividual comparisons and interocular side comparisons, significant @entity735 were seen in the foveal records. No topographical correlation between multifocal pattern ERG amplitudes and @entity227 could be found. CONCLUSIONS: In @entity227 , multifocal steady-state pattern-reversal ERG using the present stimulation was significantly reduced in its foveal records but seems to be incapable of detecting them topographically.
