Hyper-infusion pressure for diabetic membrane dissection.

Vitrectomy was performed on 17 eyes (16 cases) with diabetic macular traction detachment with highly active fibrovascular proliferative tissue. Membrane dissection was performed with the central retinal artery temporarily occluded by hyper-infusion pressure from 82 to 105 mmHg, introduced over a duration of 0.9 to 16.5 minutes (average 4.1 minutes). With this technique, nearly complete hemostasis was achieved during membrane dissection. The retina was anatomically reattached in 16 eyes (94%); visual improvement of two lines or better was obtained in 15 eyes (88%). Membrane dissection under temporary hyper-infusion pressure prevented complications by allowing good visualization, remarkably reducing the surgical time requirement.
