—After the introduction of bimanual vitrectomy, intraocular fiberoptic illuminators were devised with 20- and 19-gauge tips, and some were integrated in the membrane pick or in the infusion port.1-4 Disposable endoilluminators have become available. We modified a disposable endoilluminator by bending the 20-gauge metal shaft between 30° and 45° (Fig 1). This was accomplished manually and gently to minimize the damage to the optical fibers encased in the illuminator.One advantage of the modified probe is that it introduces a rotational dimension to the endoilluminator. Without the need to move the probe, clockwise or counterclockwise rotation of the probe can illuminate a large area of the retina (Fig 2). Consequently, viewing of the retinal periphery is accomplished without much distortion of the cornea. The probe can also be manipulated through a superonasal or inferonasal sclerotomy.
