There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Title: Collagen Photocrosslinking for Treatment of Glaucoma
Abstract:
Glaucomatous vision loss is mediated through mechanical force transduction near the optic nerve due to elevated intraocular pressure. Resulting retinal ganglion cell damage is believed to be mediated through strains in the collagenous scleral tissue adjacent to the optic nerve head (peripapillary sclera). Therefore, stiffening of the peripapiallary scleral tissues is hypothesized to be a promising treatment for glaucoma.
This work tests the hypothesis that stiffening the peripapillary scleral tissue protects against pressure-induced glaucomatous vision loss. To do so, 1) a photocrosslinking technique was developed to selectively stiffen peripapillary sclerae in vivo, 2) investigation of this technique’s effects as a potential treatment were investigated in glaucomatous rats, and 3) a theoretical computer model was created to predict crosslink distribution and magnitude for future scleral photocrosslinking procedures.
