Résumé
The intravitreal route faces many challenges in rapidly and effectively reaching posterior eye pathology, with administered therapeutics experiencing non-specific distribution around and premature clearance from ocular tissues. Nanobubbles and ultrasound may improve outcomes of intravitreally administered drugs by influencing the directionality of drug-containing particle migration. In this study, we assessed the impact of trans-scleral or corneal ultrasound application on the distribution of intravitreally-injected nanobubbles. Rhodamine-tagged gas entrapped nanobubble formulations were prepared and injected into ex vivo bovine and porcine eyes and subjected to ultrasound (1 MHz, 0-2.5 W/cm
