High-Intensity Focused Ultrasound Circular Cyclocoagulation in Glaucoma: A Step Forward for Cyclodestruction?

Figure 4

The image shows an ocular surface thermogram obtained with a digital infrared camera, of a representative patient during 6-second dose insonification, immediately after removal of the 6 o’clock hour transducer. A single evident circular red spot is well distinguishable (arrowheads), which corresponds to an area of increased temperature at the site of transducer. Asterisk indicates the nose of the patient.
