To evaluate the feasibility of whole blood in staining internal limiting membranes during internal limiting membrane peeling for macular hole.
A total of 32 consecutive patients of macular hole who need internal limiting membrane peeling were enrolled. After core vitrectomy, autologous whole blood was applied to cover macula to stain the macular area in fluid-filled vitreous cavity. The redundant blood was removed and only a very thin blood left on the macular area. The blood-stained internal limiting membrane was removed by forceps.
The membranes were effectively stained and removed. The macular hole was closed with a single surgery in 32 eyes (100%). The median best-corrected visual acuity was improved from 20/100 preoperatively to 20/40postoperatively. No fundus changes were observed during the follow-up period.
Whole blood could stain membranes and facilitate the visibility during membrane peeling. This method could prevent dye toxicity in dye-assisted membrane peeling.
