A 65-yeаr-оld mаle with а histоry оf chronic glaucoma has progressive optic nerve damage and elevated intraocular pressure. A clear corneal incision is made and viscoelastic material is injected into the anterior chamber over the lens to increase and maintain anterior chamber depth. The endoscope is inserted through the temporal incision to view the nasal ciliary processes, which is coagulated with the endpoint of shrinkage and whitening. The endoscope is moved in an arc, allowing treatment of the processes over an arc of 180° and a second corneal incision is made 90° away and 180° of ciliary processes are destroyed with laser therapy. The surgeon has completed coagulation of 270° of angle. The eye is reformed with balanced salt solution. Wounds are checked for leakage and sutures are placed to seal the wound.
