    Transscleral delivery is an emerging, high-potential method for delivering drugs to the posterior eye. If successful, it could offer non-invasiveness comparable to drops and delivery efficiency comparable to intravitreal injection.Author: Victor H Barocas, Ram K Balachandran

Transscleral drug delivery to the retina and choroid.

    https://www.ncbi.nlm.nih.gov/pubmed/12062532
    In vitro and in vivo studies suggest that the transscleral route may offer a means to achieve the goal of sustained, targeted drug delivery to the posterior segment. Potentially therapeutic concentrations of macromolecules with retention of bioactivity can be attained in the choroid and retina via minimally invasive transscleral delivery.

    Oct 31, 2001 · The utilization of some type of sustained-release delivery system would thus appear to be necessary for the successful utilization of transscleral drug delivery. An ideal sustained-release transscleral delivery system would provide controlled, long-term drug release, specific scleral site delivery, and prolong drug–sclera contact time.Author: Dayle H Geroski, Henry F Edelhauser

    3.1. Drug quantification, stability, and ability of transscleral diffusion. Relatively long drug stability is required for the proposed implant to be therapeutically efficient. The drug must be loaded into the hydrogel implant via hydrogel immersion in the drug solution. During subsequent implant application, the drug must be released from the ...Author: Ana-Irina Cocarta, Radka Hobzova, Jakub Sirc, Tereza Cerna, Jan Hrabeta, Karel Svojgr, Pavel Pochop,...

    Nov 30, 2017 · ABSTRACTIntroduction: The sclera is considered the ‘static barrier,’ a main barrier for transscleral drug delivery. The characterization of passive and iontophoretic transport across the sclera in vitro is the first step toward our ability to predict transscleral drug delivery. Although previous studies have investigated this topic, the quantitative structure permeation relationships (QSPR ...Author: S. Kevin Li, Jinsong Hao
