Abstract

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.

Özet

Amaç: Pattern elektroretinografi (PERG), ganglion hücre tabakası ve makula fonksiyonlarını değerlendirmekte kullanılan özgül bir testtir. Bu çalıþmada miyopisi olan olgularda PERG sonuçları değerlendirilmiþtir. Hastalar ve Metod: Seksen olgunun 160 gözü refraksiyon düzeylerine göre dört gruba ayrıldı. Grup 1 (kontrol grubu): 0.00 ile -0.75 D arasında, Grup 2: -1.00 ile -3.00 D arasında, Grup 3: -3.25 ile -6.00 D arasında, Grup 4: -6.25 ile -10.00 arasında refraksiyon düzeyine sahip olgulardan oluşmaktaydı. Tüm olgularda P50 ve N95 dalgalarının amplitüd ve latansları kaydedildi. Bulgular: Yüksek miyopisi olan olgularda (Grup 3 ve 4), düşük miyopisi olan olgulara göre (Grup 1 ve 2) P50 ve N95 dalga amplitüdleri daha düşük bulundu (p0.05). Sonuç: Yüksek miyopisi olan olgularda, P50 dalga amplitüdünde azalma makuler fonksiyon bozukluğundan, N95 dalga amplitüdünde azalma ganglion hücre tabakasındaki fonksiyon bozukluğundan kaynaklanabilir.
