To examine three layers of membranes detected by triamcinolone acetonide (TA) and indocyanine green (ICG) during surgery for macular hole and retinal detachme nt (MHRD) as a result of high myopia. Histologic study. We excised three layers of membranes visualized with TA and ICG that were tightly adhering to the retina l surface during vitrectomy and examined them by transmission electron microscop y. The first membrane was made of acellular collagen fibers, suggestive of vitre ous, and the second was comprised of parts of fibro-blast-like cells and colla gen fibrils, suggesting a proliferative epiretinal membrane. The third membrane was an internal limiting membrane. Multiple components of epiretinal tissue coul d be delaminated with the assistance of TA and ICG during surgery for myopic MHR D.
