Purpose: To report a case of indocyanine green (ICG)–induced scotoma after macular hole surgery. Methods:A 67–year–old woman underwent internal limiting membrane (ILM) peeling using ICG staining for a macular hole. For the staining, 0.125% ICG solution was flashed onto the macular, and immediately aspirated by a cutter. Results: The macular hole was closed, and her visual acuity improved from 20/100 to 20/30. However, Goldmann perimetry revealed a small relative scotoma nasal to the fixation point at 3 months after surgery. Ophthalmoscopy, multifocal electroretinography, and fluoresein angiography detected no abnormality in the corresponding area. Conclusions: These data suggest that the visual field defect was not caused by damage of the pigment epithelial cells or retinal neurons but most likely by damage of the nerve fibers from ICG exposure.
