Abstract

This report describes a novel therapeutic technique called photo-mediated ultrasound therapy (PUT). PUT applies synchronized short pulse duration (nanosecond) laser and ultrasound burst on targeted tissue, offering high-precision localized treatment. PUT is based on controlled induction and promotion of micro-cavitation activity in the target tissue. PUT is able to safely and effectively treat retinal neovascularization in rabbits with persistent nonperfusion up to 4 weeks after PUT in the choroidal vasculature.Clinical Relevance- PUT can selectively remove retinal angiogenesis in clinically-relevant disease models in humansized eyes (rabbit) without damaging surrounding tissue.

摘要

本报告描述了一种名为光介导超声疗法(PUT)的新型治疗技术。PUT将同步的短脉冲持续时间(纳秒)激光和超声脉冲应用于目标组织,提供高精度的局部治疗。PUT基于对目标组织中微空化活性的可控诱导和促进。PUT能够安全有效地治疗脉络膜血管系统中PUT后持续无灌注达4周的兔视网膜新生血管。临床意义——PUT可以在人眼大小(兔)的临床相关疾病模型中选择性地消除视网膜血管生成,而不损伤周围组织。
