Infusion aspiration mismatch during 25-gauge vitrectomy with conversion to 20-gauge vitrector.
We report intraoperative hypotony throughout the 25G vitrectomy procedure of an elderly patient with dense vitreous hemorrhage when switching to a 20G cutter. This was due to fluidic mismatch between the 25G infusion and 20G aspiration systems. No leakage from the sclerotomy sites or choroidal effusion was noted.
