RETINA PEARLS: Bimanual Vitreoretinal Surgery for Tractional Retinal Detachment Due to Proliferative Diabetic Retinopathy

In this issue of Retina Today, Elliott Sohn, MD, provides surgical pearls for performing bimanual vitreoretinal surgery for tractional retinal detachment due to proliferative diabetic retinopathy using 20- or 23-gauge instrumentation. We extend an invitation to readers to submit pearls for publication in Retina Today. Please send submissions for consideration to Ingrid U. Scott, MD, MPH (; or Dean Eliott, MD ( We look forward to hearing from you. —Ingrid U. Scott, MD, MPH; and Dean Eliott, MD Managing eyes with tractional retinal detachment (TRD) due to severe proliferative diabetic retinopathy (PDR) can be challenging for vitreoretinal surgeons (Figure 1). TRD from PDR, resulting from contraction of epiretinal fibrovascular proliferative membranes, requires surgery when it involves or threatens the macula or has a combined rhegmatogenous retinal detachment (RRD) component. In bimanual vitreoretinal surgery, two instruments are used simultaneously to manipulate the same tissue inside the eye. This concept typically excludes the use of a single- function light pipe as one of the instruments, although this too can be used for manipulation. Due to the complexi… [read more...]

SURGICAL UPDATES: The Next Generation Machines for Modern Vitrectomy

At the 2011 Association for Research and Vision in Ophthalmology (ARVO) meeting, the Vit-Buckle Society met to discuss three current-generation vitrectomy machines. 2010 was a banner year for vitreoretinal surgical equipment. To help start a discussion about the surgical platforms, Christopher Riemann, MD; Derek Kunimoto, MD; and Jorge Fortun, MD, presented a quick summary of the Dutch Ophthalmic USA (Exeter, NH), Bausch + Lomb (Aliso Viejo, CA), and Alcon Laboratories, Inc. (Fort Worth, TX), systems, respectively (three lectures linked to EYETUBE.NET). In the first half of the year, the Constellation Vision System (Alcon Laboratories, Inc.) gained significant traction in hospitals, universities, and some ambulatory surgical centers (ASCs). In the second half of the year, all kinds of excitement broke loose with two new machines introduced (the Associate [Dutch Ophthalmic USA]; and the Stellaris PC [Bausch + Lomb]) and the voluntary recall of the Constellation by Alcon. Indeed, the second half of 2010 was the equivalent of a soap opera. Our hospital had purchased two Constellations in the last weeks of June, just prior to the recall. In fact, our in-service training was scheduled to take place on the Mond… [read more...]

    Efrem D. Mandelcorn, MD, FRCSC; Jonathan Prenner, MD; and Charles C. Wykoff, MD, PHDIn the absence of capsular support, the ophthalmic surgeon is faced with a number of choices for implantation of an intraocular lens (IOL). Myriad techniques have been described for fixation of an IOL [read more...]
