PURPOSE: To report on the successful closure of a persistent chronic macular hole using indocyanine green (ICG) during the second surgical approach.
DESIGN: Interventional case report.
METHODS: A patient with a long standing macular hole (18 years) underwent pars plana vitrectomy with peeling of the internal limiting membrane (ILM). While no dye was used during the first operation, ICG (0.05%, Pulsion) was applied during the second procedure. The light source was turned off immediately after the ICG application until the dye was washed out after a period of 15 seconds. Tissue harvested during the second surgical approach was prepared for electron microscopy.
RESULTS: After the failure of the first operation, areas of incomplete ILM peeling could be stained using ICG and a thorough ILM removal was achieved. Postoperatively, the macular hole was closed, as confirmed by optical coherence tomography. Visual acuity increased from 20/200 to 20/50. No visual field defects were seen postoperatively. There were only few cellular elements adherent to the retinal surface of the ILM as seen during electron microscopy.
CONCLUSION: In cases where tractional forces due to incomplete ILM removal are considered responsible for the persistence of a macular hole, ICG is useful to identify areas of unpeeled ILM. Under certain safety precautions no adverse effect on functional outcome was seen.
