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

Design: Interventional case report. Methods: New micro vertical scissors were developed and used for the ablation of RAP vessels. Results: The length of the inner side of the tip is 180 μ m, which is approximately one seventh that of regular vertical scissors. The scissors handled easily and the RAP vessels were ablated with less retinal damage compared with that associated with use of standard vertical scissors. Postoperatively, intraretinal hemorrhage was reduced and hyperfluorescence seen on indocyanine green angiography resolved. Conclusions: The new micro vertical scissors developed for the ablation of RAP vessels can be used safely and effectively during this surgical procedure.展开更多

DESIGN: Interventional case report. METHODS: Images from fluorescein angiography, indocyanine green (ICG) angiography, and optical coherence tomography (OCT) were examined before and after ablation. RESULTS: The hot spot on late-phase ICG, the leakage on fluorescein angiography, the pigment epithelial detachment, and macular edema on OCT decreased postoperatively. However, a large hyperfluorescent lesion was detected on ICG 6 months postoperatively with recurrent cystoidmacular edema. CONCLUSIONS: A new RAP lesion can develop even after the original lesion seemed to resolve after ablation.展开更多
