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.展开更多

The patient also felt clunk of the patellofemoral joint and knee locking. Under arthroscopic examination, a thick and fibrous plica was found medial to patellar, and a bucket tear along the plica from medial patellar retinaculum to infrapatellar fat pad. Polarized microscopic examination showed collagen fiber fragment and loss of light reflecting property. Neuroimmunohistology suggested up-regulation of synovial plica innervation in the area around the crack. This may be related to the pain. The bucket tear of mediopatellar plicacaused pain and lock of knee are more common than previously reported.展开更多
