A 61-year-old male suffered from sudden blurred vision and superior visual field defect oculus dexter. His vision was counting fingers at 20 cm. Fundoscopy demonstrated inferior pale retina and a large embolus located at the proximal inferior retinal artery. Branch retinal artery occlusion (BRAO) was diagnosed. Initial paracentesis, topical brimonidine tartrate, oral pentoxifylline, and hyperbaric oxygen therapy were performed but showed limited improvement. Hence, he received 25-gauge vitrectomy, artificial posterior vitreous detachment, blocked retinal artery massage, and bloodletting 5 days after onset...

PURPOSE: The vitreous cortex, epiretinal membrane (ERM), and inner limiting membrane (ILM) are transparent tissues and are thus difficult to visualize. Staining these structures can increase the efficiency of a nontraumatic removal. METHODS: The surgeon performs a partial core vitrectomy and induces a posterior vitreous detachment. The vital dye is then injected into the retrohyaloid space in balanced salt solution (BSS). The dyes used are TWIN (Alchimia srl, Padova, Italy), MembraneBlue-Dual (DORC International, Zuidland, the Netherlands), and Doubledyne (Alfa Intes, Casoria, Italy)...
