目的 探讨吲哚青绿血管造影 (indocyanine green angiography,ICGA)是否对视网膜电图(electroretinogram,ERG)产生影响。 方法 采用 Topcon5 0 IA眼底照相机行 ICGA,随机抽取 2 0例 38只眼 ,采用 Neuropack 电生理记录仪检测 ICGA前后全视野 ERG反应。 结果 38只眼 ICGA前、后全视野 ERG暗视视杆细胞反应的 b波潜伏期、振幅及最大反应 a、b波潜伏期、振幅和明视 a、b波潜伏期、振幅的差异均无显著性的意义 (P>0 .0 5 )。 结论 ICGA对 ERG各反应不产生明显影响 ,ERG可于 ICGA后进行检测。
Objective To investigate whether indocyanine green angiography (ICGA) affects the electroretinogram (ERG). Methods Topcon5 0 IA fundus camera was used to perform ICGA. Twenty-eight eyes (38 eyes) were randomly selected. Neuropack electrophysiological recorder was used to detect the ERG response before and after ICGA. Results There was no significant difference in the latency, amplitude and maximal responses of a, b wave latency, amplitude and the apparent wave amplitude of a, b wave in the ERG strabismus before and after ICGA in 38 eyes Significance (P> 0.05). Conclusion ICGA has no significant effect on the ERG response, and ERG can be detected after ICGA.
