This project called “Bianco, a multimedia project on visual deficiencies” by an amazing photographer/photojournalist Stefano da Luigi was sent by photojournalist extraordinaire and friend of Webvision, Trent Nelson. Stefano da Luigi’s work in this photoessay, a winner of the Visa Pour L’Image, Perpignan 2011 Multimedia Award is a stunningly intimate series of images of people experiencing aspects of blindness or the clinical treatment of low vision. Images like these are tacit reminders of why those of us do the research we do… They are why we engage in long days and longer nights of work… They are why we fight long odds of funding and strive to change the world for people that suffer from visual deficits and blindness.
Webvision hopes that its readers will take the time to click through to these images and use them as touchstones to guide your work.
This is the first photograph in a new category, “Who’s That?”, a evolving compendium of found imagery from years back of vision scientists. The idea is that on occasion, one runs across imagery of vision scientists from other times and it makes for a compelling look back at history. At the 2007 ARVO, Don Fox helped set up a presentation on the early years of ARVO where he showed some images of John Dowling, George Wald, Brian Boycott and more while Bob Barlow, John Dowling and Harris Ripps spoke for almost two hours about the early history of ARVO and neuroscience research at the Marine Biology Lab at Woods Hole.

We here at Webvision have a certain fondness for insects and believe that our understanding of vision and visual pathways can benefit greatly from the study of insect visual systems. Our understanding of visual processing is actually pretty limited and simpler visual systems to study from eye to brain are found in insects compared to vertebrates.

I missed this paper in the chaos and runup to ARVO, but its conclusions are remarkably compelling. Imagine that you were blind for years, perhaps from birth and suddenly, you were able to see with perfect clarity. Would you be able to recognize items like a pyramid, a box or a sphere by sight when you only knew these objects previously by touch?

We here at Webvision love art, particularly scientific art or scientifically inspired art. Friend of Webvision, Nancy Parmalee pointed “Retina” out the other day on Twitter and it turns out “Retina” is/was an art installation in 2002 by Deborah Aschheim at the Pasadena Armory Center for the Arts. I don’t know if it is still in place. Any additional information from the community on this installation or on its current status would be appreciated.
Efforts to explore chromosome 10q26, a major candidate region associated with age-related macular degeneration (AMD) have proven difficult and controversial. This particular region of interest is two neighboring genes, ARMS2 and HTRA1. However, efforts in trying to explore the functional involvement of either HTRA1 or ARMS2 in AMD have proven to be difficult and have often yielded conflicting results.

This is normal fluorescein angiogram of a human retina showing the tunic of capillaries that surround the fovea and rather nicely illustrates the Foveal Avascular Zone (FAZ) discussed in The Simple Anatomy of The Retina. Photograph was made by James Gilman of the Moran Eye Center.
This paper is the result of a collaborative effort between Bryan William Jones, Mineo Kondo and Hiroko Terasaki, Carl Watt, Kevin Rapp, James Anderson, Yanhua Lin, Maggie Shaw, Jia-Hui Yang and Robert Marc.
This work presents a substantial advance in models of Retinitis pigmentosa (RP), an set of inherited blinding diseases characterized by progressive loss of retinal photoreceptors. Continue reading “Notable Paper: Retinal Remodeling in the Tg P347L Rabbit, a Large-Eye Model of Retinal Degeneration”
This is the fourth paper in the category, 100 Papers You Should Read (in vision science).
William Rushton once said “The trouble with colour vision is the mentality of those that write on it-and of those that read. In most aspects of physiology it is sufficient to offer a fairly plausible and adequate hypothesis; but colour visionaries want nothing less than the truth. The cause of this unreasonable demand lies in this, that whereas nearly all the phenomena of nature are simply observed, those of sensory physiology can also be experienced. So in colour vision we perceive the essential hollowness of formal scientific explanation.”
