목적 : Indocyanine green (ICG) staining to assist internal limiting membrane peeling during pars plana vitrectomy is a commonly performed procedure in macular hole surgery. Since ICG dye toxicity to the retina is mentioned in number of publications, we analyzed the duration and the pattern of persistence of residual ICG dye after macular hole surgery.
방법 : A retrospective chart review was performed on 11 eyes of 10 patients who had undergone pars plans vitrectomy with ICG guided ILM peeling for repair of macular hole. One patient was treated in both eyes and two patients were reoperations. Seven patients were treated in one eye and was primary surgical procedure. We observed residual ICG fluorescence using Spectralis HRA (Heidelberg Engineering, Heidelberg, Germany) bluepeakTM autofluorescence imaging system using 810nm ICG filter.
결과 : When imaged at 1 month after surgery, macular hole was usually closed in all except one patient who had a chronic macular hole beyond two years. ICG autofluorescence was found even at 22months after surgery in one patient and usually showed hyperfluorescence at the fovea and multiple stippled hyperfluorescent dot pattern surrounding the fovea and sometimes located along the vessels. There was no correlation between persistent hyper fluorescence and visual acuity.
결론 : We can observe ICG autofluorescence even up to 22 months after surgery. Postoperative visual acuity may not be related to the duration and the pattern of persistent ICG dye. Therefore the extent of ICG toxicity requires further investigation.
