Bimanual bipolar diathermy for treatment of bleeding from the anterior chamber angle.

We used a modified bimanual bipolar diathermy technique to treat bleeding vessels in the anterior chamber angle in two patients. We attached one lead of a Mentor Wet Field coagulator to an instrument positioned in the anterior chamber angle at the bleeding site, and attached the second lead to a needle positioned externally at the corneoscleral limbus in the same meridian. Diathermy current passed between the instrument tips to coagulate the bleeding vessels.
