Multiple components of epiretinal tissues detected by triamcinolone and indocyanine green in macular hole and retinal detachment as a result of high myopia.

PURPOSE: To examine three layers of membranes detected by triamcinolone acetonide (TA) and indocyanine green (ICG) during surgery for macular hole and retinal detachment (MHRD) as a result of high myopia.
DESIGN: Histologic study.
METHODS: We excised three layers of membranes visualized with TA and ICG that were tightly adhering to the retinal surface during vitrectomy and examined them by transmission electron microscopy.
RESULTS: The first membrane was made of acellular collagen fibers, suggestive of vitreous, and the second was comprised of parts of fibroblast-like cells and collagen fibrils, suggesting a proliferative epiretinal membrane. The third membrane was an internal limiting membrane.
CONCLUSIONS: Multiple components of epiretinal tissue could be delaminated with the assistance of TA and ICG during surgery for myopic MHRD.
