Canthotomy and cantholysis prior to ultrasound circular cyclocoagulation (UC3 Eye Tech Care) in refractory glaucoma.

Case Report: The case is presented on a patient with primary open-angle glaucoma treated with the novel ultrasound circular cyclocoagulation technique (UC3 [EyeTechCare, Rillieux La Pape, France]), who had previously undergone glaucoma surgery. Due to having extreme palpebral rigidity, worsened by the pre-operative local anesthesia injections, a canthotomy and cantholysis were needed to correctly position of the UC3 probe cone. Clinical outcome as regards the IOP and the surgical wound was very satisfactory.

Discussion: In complex cases of refractory glaucoma in which cyclo-destructive surgery is limited for anatomical reasons, a complementary oculoplasty technique may be a good option.
