    Exploring safety, efficacy of high-intensity focused ultrasound in glaucoma

    New circular cyclocoagulation technique is noninvasive, repeatable and relatively pain-free



    Circular cyclocoagulation with HIFU is safe and effective. Compared with lasers, the selective ablation of ciliary bodies in the procedure and the controlled energy absorption, unrelated to ciliary bodies’ pigmentation, reduce both the impact on adjacent tissues and the hypotony risk (see Figure 2).

    The results after the first treatment are comparable to those reported in previous trials.4-7 In conclusion, these data demonstrated a possible step-by-step successful approach in most refractory glaucomatous eyes, with the UCP procedure demonstrating a good safety profile, despite multiple administrations.

    Some final take-home messages are:

    ·       This procedure is non-invasive (the eye remains closed) and repeatable with very low postoperative side effects;

    ·       UCP is selective for refractory glaucomas and reduces the risk of postoperative hypotony compared with diode laser procedure;

    ·       It is a relatively pain-free procedure;

    ·       UCP can be performed even in eyes with residual visual acuity.
