Moran Eye Center International Outreach

South Sudan_Moran Eye Center

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.

Complicated Retinal Detatchment

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.”

Images graciously provided to Webvision by Cyrie Fry of the Moran Eye Center.

Retinoid Receptors Trigger Neuritogenesis in Retinal Degenerations

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.  Continue reading “Retinoid Receptors Trigger Neuritogenesis in Retinal Degenerations”
