Iatrogenic Retinal Dialysis from instruments introduced through the sclerotomy

Bernd Kirchhof
Occasionally and usually unexpected the instrument (light pipe, cutter, forceps) introduced through the sclerotomy pushes forward condensed vitreous that is connected to the peripheral retina. The stress from the induced traction is usually sufficient to create a more or less large dialysis. Being aware of the risk, peripheral fundus inspection with indentation and eventual cryopexy or endolaser is the treatment of choice, not necessarily combined with a tamponade in otherwise attached retina.
