Abstract
PURPOSE: To evaluate dye retention in the fundus after indocyanine green (ICG)-assisted internal limiting membrane peeling. METHODS: Ten eyes with stage 3 or 4 nondiabetic idiopathic macular hole (MH group) and six eyes with diffuse diabetic macular edema (DM group) were studied. The fundus was examined with 780-nm infrared illumination by a scanning laser ophthalmoscope (SLO) after ICG-assisted internal limiting membrane peeling. The postoperative follow-up period ranged from 6 to 12 months (mean+/-SD, 3.7+/-2.6 months). RESULTS: Fluorescence from ICG was detected in all studied eyes in both groups up to 6 months after surgery. At 9 months after surgery, ICG fluorescence was visible in all eyes of the DM group, but in only one-third of eyes of the MH group. No fluorescence was detected in fellow eyes that had not been operated on. CONCLUSION: The present study using SLO revealed that ICG remains in the fundus for over 6 months after surgery. The results also suggested that a longer time might be required for dye clearance from the diabetic retina than from the nondiabetic retina. Copyright (c) Japanese Ophthalmological Society 2006.
