Eye injuries caused by high intensity macro and micro focused ultrasound treatment: a case report.

BACKGROUND

High Intensity Macro and Micro Focused Ultrasound ( HIFU) is a safe and effective method for the treatment of skin laxity. However, the application of high-intensity focused ultrasound energy on eyelids has been associated with potential ocular complications including traumatic cataract, iridocyclitis, and conjunctival hemorrhage, among others.

CASE PRESENTATION

A 40-year-old female developed blurred vision in her left eye after receiving HIFU treatment on binocular eyelids, and her left far vision was 20/66. The examination revealed left eye iris depigmentation and conjunctival hemorrhage. Both eyes exhibited multiple white streaking or tadpole-shaped opacities in the lenses.

CONCLUSION

Excessive ultrasonic energy generated by HIFU can cause protein denaturation, leading to conditions such as traumatic cataract, visual impairment, injuries to the iris and conjunctiva when applied to the eyes. We recommend that individuals undergoing cosmetic treatment in the periorbital region should be highly aware of the possible ocular side effects.
