The patient has known chronic glaucoma, more severe in the left eye. She is brought to the outpatient procedure suite and anesthetized with a periocular anesthetic. The left eye is prepared and sterilely draped, followed by insertion of a lid speculum. A clear corneal incision is made temporally with the diamond blade approximately 3.4 mm in width. Viscoelastic material is injected into the anterior chamber over the pupil and lens to increase and maintain anterior chamber depth. Viscoelastic is then injected under the iris for 180° to visualize the ciliary body processes with the endoscope. The endoscope is inserted through the temporal incision, viewing the nasal ciliary processes. The ciliary processes are coagulated through the endoscope with the endpoint of shrinkage and whitening.
