Abstract

Cone electroretinograms (ERGs) in response to different color flashes were examined using a Ganzfeld stimulus in 19 eyes after successful retinal detachment surgery. In the operated eyes, the short wavelength sensitive (S-) cone b-wave was reduced more than the mixed long (L-) and middle (M-) wavelength sensitive cone b-waves. The ratio of the S-cone ERG b-wave amplitude between operated eyes and fellow eyes was significantly lower than the L- and M-cone ERG b-waves (P < .01). These ERG results indicated that the S-cone system is more impaired than the L- and M-cone systems after retinal detachment surgery.

摘要

在19只视网膜脱离手术成功后的眼睛中，使用全视野刺激检查了对不同颜色闪光的视锥细胞视网膜电图（ERG）。在手术眼中，短波长敏感（S-）视锥细胞的b波比混合的长（L-）和中（M-）波长敏感视锥细胞的b波减少得更多。手术眼与对侧眼之间S视锥细胞ERG b波振幅的比值明显低于L和M视锥细胞ERG b波（P < 0.01）。这些ERG结果表明，视网膜脱离手术后S视锥细胞系统比L和M视锥细胞系统受损更严重。
