Abstract

• A fiberoptic illuminated infusion cannula for posterior segment surgery allows the introduction of viscoelastic substances under preretinal membranes in diabetics, defining the vascular epicenters and making scissors delamination easier and safer. This technique has been most helpful in diabetics who have an attached posterior hyaloid. It appears to reduce the incidence of posterior breaks. We have used this instrument successfully in 12 patients with diabetes who have severe fibrovascular proliferation with or without retinal detachment.
