As opposed to additional vital dyes such as for example indocyanine green (ICG), BBG was proven to possess an excellent protection profile offering adequate anatomical and practical postoperative outcomes1,2. However, the presence of epiretinal membrane (ERM) formation may impair sufficient staining and complete removal of the ILM, which may result ERM recurrences due to residual ILM fragments including indefinite extent of cells and collagen remnants at the vitreal side of the ILM3. In a previous study Shimada et al.4 found BBG has high affinity to ILM and low affinity to ERM. Additionally, Schumann et al.5 reported BBG showed no staining with ERM specimens intra-operatively. In this report, we present our observations about BBG’s staining features for ERM, and outcomes of the longer exposure time for BBG under air pressure using optical coherence tomography (OCT) and multifocal electroretinogram (mfERG). buy Aldoxorubicin LEADS TO 4 instances ERM was stained with BBG intensely.

Histopathologic study of the ERM exposed fibroblast like cells along with intensive connective cells. The ILM was absent of cells and handful of connective cells was noticed (Fig. 2).

Discussion ERM recurrence is observed in approximately %10 of cases after surgery6. The reasons for recurrence are the incomplete removal of the ERM and the persisted ILM after ERM peeling, even the ERM seems to have been completely peeled3. To enhance the visualization of these transparent or semitransparent structures and to overcome ERM recurrence, various staining methods have been used, including indocyanine green (ICG), trypan blue (TB), triamcinolone acetonide (TA), and brilliant blue G (BBG)7. Of these stains, BBG shows no retinal toxicity or adverse effects related to the dye were observed in animal and human studies2. ILM that persists after ERM peeling acts as a scaffold for cell proliferation, leading to ERM recurrence. In a previous study, Shimada et al.4 found that BBG has low affinity to ERM and recommended the reapplication of BBG after.
