Description

 

Emerging molecular, gene, and cell-based therapeutics targeting ocular diseases could prevent and potentially reverse cell degeneration and subsequent vision loss. However, reliable and safe delivery of these therapeutics into targeted ocular layers is an ongoing concern of the FDA, which may affect the advancement of these potentially life-changing new treatments. To increase delivery accuracy, reliability, safety, and ease of the new molecular therapeutic procedures, we propose to develop B-scan OCT-guided robotic-assisted subretinal therapeutic delivery techniques. 

Our group is collaborating with VUMC researchers Dr. Karen Joos and Dr. Jin-Hui Chen on developing OCT-guided robotic control algorithms for the targeted delivery of drugs into specific locations within the retina. As part of our research, we will be enabling robot-assisted hand-held tools and collaborative (hand-on-hand) robotic tools to assist and semi-automate the last step of targeted drug delivery. We will be comparing these modes of assistance via in-vivo studies, enucleated cadaveric eyes, and bench-top phantom models.
