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.
