Diseases affecting the posterior segment of the eye are currently treated with monthly to bimonthly intravitreal injections, which can predispose patients to severe albeit rare complications like endophthalmitis, retinal detachment, traumatic cataract, and\/or increased intraocular. In this study, we show that one time moderate intensity focused ultrasound (MIFU) treatment can facilitate the penetration of large molecules across the scleral barrier, showing promising evidence that this is a viable method to deliver high molecular weight medications not invasively. To validate the efficacy of the drug delivery system, IVT injections of vascular endothelial growth factor (VEGF) were used to create an animal model of retinopathy. The creation of this model allowed us to test anti-VEGF medications and evaluate the efficacy of the treatment. In vivo testing showed that animals treated with our MIFU device improved on the retinal tortuosity and clinical dilation compared to the control group while evaluating fluorescein angiogram (FA) Images.<\/jats:p>","DOI":"10.34133\/2022\/9840678","type":"journal-article","created":{"date-parts":[[2022,6,17]],"date-time":"2022-06-17T23:45:14Z","timestamp":1655509514000},"source":"Crossref","is-referenced-by-count":2,"title":["Development of Moderate Intensity Focused Ultrasound (MIFU) for Ocular Drug Delivery"],"prefix":"10.34133","volume":"2022","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2685-4410","authenticated-orcid":false,"given":"Alejandra","family":"Gonzalez-Calle","sequence":"first","affiliation":[{"name":"USC Ginsburg Institute for Biomedical Therapeutics, University of Southern California, Los Angeles California, USA"},{"name":"USC Roski Eye Institute, Keck School of Medicine, University of Southern California, Los Angeles California, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Runze","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering, University of Southern California, Los Angeles California, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Isaac","family":"Asante","sequence":"additional","affiliation":[{"name":"USC Ginsburg Institute for Biomedical Therapeutics, University of Southern California, Los Angeles California, USA"},{"name":"USC Roski Eye Institute, Keck School of Medicine, University of Southern California, Los Angeles California, USA"},{"name":"USC School of Pharmacy, University of Southern California, Los Angeles California, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Juan Carlos","family":"Martinez-Camarillo","sequence":"additional","affiliation":[{"name":"USC Ginsburg Institute for Biomedical Therapeutics, University of Southern California, Los Angeles California, USA"},{"name":"USC Roski Eye Institute, Keck School of Medicine, University of Southern California, Los Angeles California, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stan","family":"Louie","sequence":"additional","affiliation":[{"name":"USC Ginsburg Institute for Biomedical Therapeutics, University of Southern California, Los Angeles California, USA"},{"name":"USC Roski Eye Institute, Keck School of Medicine, University of Southern California, Los Angeles California, USA"},{"name":"USC School of Pharmacy, University of Southern California, Los Angeles California, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1527-3020","authenticated-orcid":false,"given":"Qifa","family":"Zhou","sequence":"additional","affiliation":[{"name":"USC Ginsburg Institute for Biomedical Therapeutics, University of Southern California, Los Angeles California, USA"},{"name":"USC Roski Eye Institute, Keck School of Medicine, University of Southern California, Los Angeles California, USA"},{"name":"Department of Biomedical Engineering, University of Southern California, Los Angeles California, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mark S.","family":"Humayun","sequence":"additional","affiliation":[{"name":"USC Ginsburg Institute for Biomedical Therapeutics, University of Southern California, Los Angeles California, USA"},{"name":"USC Roski Eye Institute, Keck School of Medicine, University of Southern California, Los Angeles California, USA"},{"name":"Department of Biomedical Engineering, University of Southern California, Los Angeles California, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"221","published-online":{"date-parts":[[2022,6,17]]},"reference":[{"issue":"14","key":"e_1_3_4_1_2","doi-asserted-by":"crossref","first-page":"2010","DOI":"10.1016\/j.addr.2005.09.004","article-title":"Topical and systemic drug delivery to the posterior segments","volume":"57","author":"Hughes P.
