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

Figure 3

Anterior segment optical coherence tomography of scleral modifications after successful UCCC. (a–c) Second-generation probes (8-second treatment; 4 mm wide active area); (d–f) first-generation probes (6-second treatment; 2.5 mm wide active area). Intrascleral hyporeflective spaces (arrows and asterisks), with a different degree of internal reflectivity, are clearly recognizable within the stroma. These spaces are prominent after seven days from the treatment (a), and persist, even though reduced, after one (b) and three (c) months. No significant macroscopic differences are detectable between the two generation probes, even though the current probes seem to induce a greater scleral delamination. Scans were taken at the superior-temporal quadrants, 3 mm from the site of previous filtration surgery.
