We developed an endolaser probe that is capable of delivering argon laser light for photocoagulation of retinal breaks or vascular fronds. Energy is transmitted through a fiberoptic cord from a console outside of the surgical area to an endolaser probe inside the operating suite. The probe can be fired into fluid- or gas-filled media. With the use of this system, panretinal photocoagulation can be performed rapidly and conveniently during a vitrectomy procedure. We have also successfully managed posterior retinal tears and bleeding fibrovascular fronds with this system.
