UW Scientists, Biotech Firm May Have Cure For Colorblindness

An anonymous reader writes with news about a possible cure for colorblindness. "For the more than 10million Americans with colorblindness, there's never been a treatment, let alone a cure, for the condition that leaves them unable to distinguish certain hues. Now, for the first time, two University of Washington professors have teamed with a California biotech firm to develop what they say may be a solution: a single shot in the eye that reveals the world in full color. Jay and Maureen Neitz, husband-and-wife scientists who have studied the vision disorder for years, have arranged an exclusive license agreement between UW and Avalanche Biotechnologies of Menlo Park. Together, they've found a new way to deliver genes that can replace missing color-producing proteins in certain cells, called cones, in the eyes."

      It's not so cut and dried, actually. A lot of colour vision requires processing in the cortex so there isn't necessarily a clear cut relationship between the number of cone classes and an animal's colour acuity. A great example is the mantis shrimp which has a large number of different cone classes yet has crap colour vision. I don't know what bird colour acuity is or how it compares to our own, but don't assume it's necessarily better because they are tetrachromats. For instance, the wikipedia says that pigeons are pentachromats but they may not have access to the fifth channel. Many birds also have colour oil droplets in front of some photoreceptors in order to further tune their range. In effect, this may give them more than 4 cone classes.

I had the delight of attending several of teking Jerry's "General Physiology" course at MIT, which was filled with weird anecdotes and a profound scientific view of "how do things *really* work, and how did they get that way" with the evolutionary theory of ambulatory knishes avoiding predation by hungry students in Harvard Square.

      Jerry's experiments with electrodes on individual visual neurons and work with other colleagues made very clear that much of vision is edge detection in the retina itself, which explains why that silly dress color illusion works so well. The cortex does not get raw color: it gets pre-processed information about "this region is much redder than that region, and far less blue and green compared to other regions, so it's definitely red". And I'm afraid it's also why the very silly "let's put grids of electrodes in the back of the eye" is never going to to work well. The electrodes are immersed in salty fluid, and the current spreads *much* too far: it recruits far too many of the pre-processing cells, and even putting a brilliantly designed electrode grid on the retina itself would skip all the subtle pre-processing in the retina and require much more complex pre-processing than visual researches like to even think about.

But like a tetrachromatic woman, unless industry started making cameras & video displays that reproduced that "near-infrared" hue as a primary color, you'd be permanently destroying any sense of color aesthetics you've ever had and guaranteeing that nearly everything would look worse under most real-world non-daylight lighting conditions.

      UV? Not happening without artificial corneas. Normal human corneas yellow with age & filter out UV light.

In a trichromat, all your reds are, say, 6, all your greens are 5, and all your blues are 4. In a green anomaly, all your reds are 6, all your greens are 5.8, and all your blues are 4.

Accordingly, "Ao" was assigned "green" first but as the concept of "Blue" started to materialize, "Midori" became the new "Green" so that "Ao" could start covering things that were "Blue." That would explain why phrased implying youth ("He is still Green", etc. . .) use the character for "Ao," as they are old phrases that would have been invented before the concept of "Blue" came along.

    Turns out the biological lens of your eye blocks UV light, but if you get an artificial lens, your retinas can register UV light.

    There's some natural variation....

    This has been understood for some time. As others have mentioned, various military orgs have used teams with varied color vision as a way of "seeing through" camouflage. Biologists have suggested that the variety in human color vision is adaptive, giving our hunting ancestors' teams an improved chance of spotting spotting prey against various backgrounds, and the addition of dogs (with their very different color vision from ours) improved this teamwork. This is all hypothetical, though, since (as far as I know) it hasn't actually been tested scientifically.

    Back in high school (in the 60s), I had a science teacher who did a good illustration of it all. He made the usual demo of a spectrum using a prism, on a sheet of white paper. Then he had students come up and mark the visible ends of the spectrum, covering up each student's marks with another sheet of paper before the next student made their marks. The result was two columns of dots that didn't line up at all; their variants was around 10% of the width of the spectrum. I'd made marks that I could identify, and saw that my UV mark was right at the average point, while my IR mark was one of the farthest out. This explained some things I'd already noticed about the ways that different people saw colors.

    This has been known to the photography industry since color film was first produced. Different varieties of film (and now CCDs) have different sensitivities, and different photographers have different preferences for brands of film based on this.

    One of my funny personal anecdotes on the topic was once (in Jr High, as I recall), I asked some visitors why the front-left panel of their car was a different color than the rest of the car. They gave me a funny look, then said the car was all black, which everyone else present agreed with. I objected that only that one panel was black; the rest of the car was a deep red. This got me more funny looks, and the fellow who owned the car said that the car had been in a minor accident that damaged the front-left panel, so it was replaced. After that, my family thought I had something called "black-red color blindness" (which is odd, because I was actually the only one without that defect ;-). I was taken to an optometrist, who verified the "condition", but assured my parents that it wasn't a significant problem, and didn't need treating. Actually, there was a simple treatment: glasses that block near-IR light, and I've accidentally got several sunglasses that do just that, making for oddly muted reds.

    As I got more into photography, I eventually noticed that my eyes have slightly different color vision, with things looking slightly bluer in the left eye and slightly redder in the right eye. This seems to be extremely common, actually, though most people don't notice it until it's mentioned and they start trying to spot it in different lighting condition.

I've been waiting all my life for this; color blindness cost me a career as a pilot, and only in 2012 did I get a chance to get in through the side door (passed the Farnsworth and map tests and got a nice Letter of Evidence from the FAA, thanks OK City FSDO for the great help ^_^). Now tech will catch up with me again, and even if it was needles up the urethra, shut up, take my money, let's DO THIS. Everyone who's ever been denied flying because of this stupid condition will be lined up to take however many needles are necessary.

    If this pans out, the Drs. Neitz have free beer and food wherever I reside for the rest of my natural lifespan.

    Preacher: Are you a sinner? Do you wish to be saved?

    Dr. James Xavier: Saved? No. I've come to tell you what I see. There are great darknesses. Farther than time itself. And beyond the darkness... a light that glows, changes... and in the center of the universe... the eye that sees us all.

    I'm red-green colorblind too & wear glasses all the time. The only time it's a big factor for me is with light hues. Dark red/green I can tell the difference. Traffic lights have position (& they do look different to me anyway). Heck, I didn't find out about it until I was out of college & saw the Ishihara tests.

      The dual color LEDs in the network closet? Not so much. I wouldn't mind having an inexpensive magnifying glass to make one or the other pop.
