This happens when the normally clear aqueous humor becomes less transparent, thus blocking the visual axis and by intraocular pressure elevation due to blockage of the trabecular meshwork, as seen in secondary open-angle glaucoma (SOAG). Some of these \u201cparticle-related pathologies\u201d acquire ocular conditions like pigment dispersion syndrome, pseodoexfoliation and uveitis. Others are trauma-related, such as blood cell accumulation in hyphema. While medical and surgical treatments exist for SOAG, there is a notable absence of effective preventive measures. Consequently, the prevailing clinical approach predominantly adopts a \u201cwait and see\u201d strategy, wherein the focus lies on managing secondary complications and offers no treatment options for particulate matter disposal. We developed a new technique utilizing standing acoustic waves to trap and direct intraocular particles. By employing acoustic trapping at nodal regions and controlled movement of the acoustic transducer, we successfully directed these particles to specific locations within the angle. Here, we demonstrate control and movement of polystyrene (PS) particles to specific locations within an in vitro eye model, as well as blood cells in porcine eyes (ex vivo). The removal of particles from certain areas can facilitate the outflow of aqueous humor (AH) and help maintain optimal intraocular pressure (IOP) levels, resulting in a non-invasive tool for preventing secondary glaucoma. Furthermore, by controlling the location of trapped particles we can hasten the clearance of the AH and improve visual acuity and quality more effectively. This study represents a significant step towards the practical application of our technique in clinical use.<\/jats:p>","DOI":"10.3390\/mi15060786","type":"journal-article","created":{"date-parts":[[2024,6,17]],"date-time":"2024-06-17T12:48:40Z","timestamp":1718628520000},"page":"786","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Harnessing Standing Sound Waves to Treat Intraocular Blood Cell Accumulation"],"prefix":"10.3390","volume":"15","author":[{"given":"Avraham","family":"Kenigsberg","sequence":"first","affiliation":[{"name":"Department of Chemistry, Institute of Nanotechnology and Advanced Materials, Bar-Ilan University, Ramat Gan 5290002, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2683-7787","authenticated-orcid":false,"given":"Shany","family":"Shperling","sequence":"additional","affiliation":[{"name":"Sackler Faculty of Medicine, Tel Aviv University, Tel Aviv 6997801, Israel"},{"name":"Goldschleger Eye Institute, Sheba Medical Center, Tel Hashomer, Ramat Gan 5262000, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ornit","family":"Nagler-Avramovitz","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Institute of Nanotechnology and Advanced Materials, Bar-Ilan University, Ramat Gan 5290002, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Heli","family":"Peleg-Levy","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Institute of Nanotechnology and Advanced Materials, Bar-Ilan University, Ramat Gan 5290002, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6600-2100","authenticated-orcid":false,"given":"Silvia","family":"Piperno","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Institute of Nanotechnology and Advanced Materials, Bar-Ilan University, Ramat Gan 5290002, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alon","family":"Skaat","sequence":"additional","affiliation":[{"name":"Sackler Faculty of Medicine, Tel Aviv University, Tel Aviv 6997801, Israel"},{"name":"Goldschleger Eye Institute, Sheba Medical Center, Tel Hashomer, Ramat Gan 5262000, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8717-1659","authenticated-orcid":false,"given":"Ari","family":"Leshno","sequence":"additional","affiliation":[{"name":"Sackler Faculty of Medicine, Tel Aviv University, Tel Aviv 6997801, Israel"},{"name":"Goldschleger Eye Institute, Sheba Medical Center, Tel Hashomer, Ramat Gan 5262000, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2288-5375","authenticated-orcid":false,"given":"Hagay","family":"Shpaisman","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Institute of Nanotechnology and Advanced Materials, Bar-Ilan University, Ramat Gan 5290002, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9264-764X","authenticated-orcid":false,"given":"Noa","family":"Kapelushnik","sequence":"additional","affiliation":[{"name":"Sackler Faculty of Medicine, Tel Aviv University, Tel Aviv 6997801, Israel"},{"name":"Goldschleger Eye Institute, Sheba Medical Center, Tel Hashomer, Ramat Gan 5262000, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,6,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"154","DOI":"10.1097\/ICU.0000000000000352","article-title":"Update on Pigment Dispersion Syndrome and Pigmentary Glaucoma","volume":"28","author":"Okafor","year":"2017","journal-title":"Curr.
