Here on Webvision, our goal is retinal education and even though Webvision is hosted here at the Moran Eye Center, we nevertheless try to include as much of the wider community as possible in posts and in content, though we will point out work that comes of of the Moran Eye Center from time to time. So, while we compiling chapters for information as well as posts to the front page here that we hope contain informative items relevant to the retina and the retinal research community, it is important from time to time to step back and ask why it is that we study the retina and get a bigger picture view of what role all of this biology plays in peoples lives.
This set of images (click the image above to enlarge) are optical coherence tomography (OCT) images of retained perfluoro-octane (PFO) droplets after repair of a complicated retinal detachment. PFO is a good surgical tool to help reattach the retina as they force sub retinal fluid out of any retinal tears and helps adhere the retina to the back of the globe. PFO also helps localize the margins of retinal detachments, and reduces the height of the retinal detachment which assists in surgical laser photocoagulation. Per Dr. Bernstein, “These subretinal droplets of PFO can remain in place indefinitely and cause minimal visual symptoms as long as they are not under or near the fovea.”
This paper by Y Lin, BW Jones, A Liu, JF Tucker, K Rapp, L Luo, W Baehr, PS Bernstein, CB Watt, JH Yang, MV Shaw and RE Marc examines the neuronal sprouting or neuritogenesis components of retinal remodeling found in retinal degenerative disease and describes a control process for retinoid X receptors (RXRs) in neuritogenesis.

ARVO 2011 has come and gone. Its taken me a couple of weeks to get through the post ARVO chaos and get caught up on my own work before posting some of the snapshots, but here they are. If you’d like to post your snapshots from ARVO here, send me an email (firstname.lastname@example.org) and we’ll arrange to add them to the list and credit you appropriately.
