Description
Summary:[LANGUAGE= "English"] Purpose: Pattern electroretinography (PERG) is a specific test for the analysis of functions of ganglion cells and macula. In this study, the authors investigated the PERG recordings in myopia.Subjects and Methods: Four groups were formed according to the refraction of 160 eyes of 80 myopic and control subjects as follows: Group 1 (Controls): Between 0.00 and -0.75 D; Group 2: -1.00 and -3.00 D; Group 3: -3.25 and -6.00 D; Group 4: -6.25 and. 10.00 D. Amplitudes and latencies of P50 and N95 waves were recorded in all subjects.Results: P50 and N95 wave amplitudes were lower in high myopes (Groups 3 and 4) than low myopes (Groups 1 and 2; p0.05).Conclusion: Reduction in the amplitudes of P50 may be caused by macular dysfunction and reduction in the amplitudes of N95 may show the functional impairment of ganglion cells in high myopia.
