FDA approves software for iPhone-based vision test
The FDA recently gave clearance to Vital Art and Science Inc. (VAS) to market software which enables people with degenerative eye conditions such as macular degeneration and diabetic retinopathy to monitor their vision at home with their iPhone. The software, which is called myVisionTrack, isn't a replacement for regular visits to the doctor, but rather allows patients to keep tabs on their vision in between visits with eye care professionals. Using a proprietary patented shape-discrimination hyperacuity (SDH) test, myVisionTrack enables patients to regularly assess their vision function. The device stores test results, tracks disease progression and automatically alerts a healthcare provider if it suspects significant deterioration of visual function in the patient. In the video below, VAS President Mike Bartlett -- who previously worked for many years at Texas Instruments -- demonstrates how the software works and why it's so important. VAS notes that retinal diseases affect approximately 40 million individuals worldwide and 13 million in the United States. While treatments have been developed to deal with degenerative eye conditions, early diagnosis is of paramount importance. Notably, the FDA clearance is only applicable when the software is run on an iPhone 4S. Consequently, the software won't be available as a general download and will only be pre-loaded onto iPhone 4S devices by the company. That said, VAS hopes that a downloadable version of the software will become available sometime in the future. In the meantime, Bartlett is hoping that his company's software will be utilized in conjunction with clinical drug trials. Speaking to mobihealthnews, Bartlett explained: Right now we're looking for collaboration opportunities like clinical drug trials. In all of the clinical drug trials [for degenerative eye diseases], all of the data is being collected in the clinic. We want to enable them to collect data as often as hourly or daily instead of every month or so. Because of the nature of vision problems, we expect the first big deployments will be done by the drug companies. iOS devices being used to assist the vision impaired is of course nothing new. The iPad's ability to zoom in extremely close on pictures has proven to be very beneficial for individuals diagnosed with macular degeneration. Furthermore, a study presented at the the American Academy of Opthalmology this past November noted that tablets with backlit screens like the iPad help individuals with degenerative eye conditions read faster and more comfortably.
Alt-week 7.28.12: social mathematics, Pluto's moons and humans-on-a-chip
Alt-week peels back the covers on some of the more curious sci-tech stories from the last seven days. It's a beautiful world we live in. And, while the sweet and romantic part is debatable, strange and fantastic is not. Our universe is one populated by non-planetary celestial bodies with their own non-planetary satellites, high school social hierarchies based on predictable mathematical formulas and military-funded "gut-on-a-chips." It's a weird place filled with weird stories, and we just can't get enough of it. So, what has the last seven days brought us from the fringes of science and tech? Keep reading after the break to find out. This is alt-week.
Subretinal implant uses light instead of batteries, shows promise in initial testing
There's been significant progress in bringing sight to the blind in recent years, and this looks set to continue that miraculous trend. Scientists at Stanford University have invented a subretinal photodiode implant for people who have lost their vision due to degenerative retinal diseases. Existing tech involves batteries and wires, but the new implant works without such crude appendages. Instead, it's activated by near-infrared beams projected by a camera that's mounted on glasses worn by the patient and can record what the patient sees. The beams then stimulate the optic nerve to allow light perception, motion detection and even basic shape awareness. It hasn't actually been tested with humans just yet, but the first few rodents volunteers have yet to lodge a single complaint.
Intel drops $21 million for ten percent stake in eye-tracking firm Tobii
Tobii has managed to impress quite a few folks with its eye-tracking technology -- most recently in the form of the "Eye Asteroids" arcade game -- and it looks like Intel has been paying particularly close attention to the company. As Computer Sweden reports, Intel (or Intel Capital, specifically) has now shelled out roughly $21 million to buy a ten percent stake in the Swedish company, which hopes to soon see its eye-tracking system used in everything from desktops and laptops to phones and even vehicles. Presumably, having Intel at the table will give it a considerable boost in those endeavors.
New high-precision eye surgery robot helps doctors stay sharp
A researcher at the Netherland's Eindhoven University of Technology has invented a new type of eye surgery robot designed to steady the ophthalmologist's hands and minimize error -- always a good thing when it comes to having needles and knives near your peepers. Kind of like an Igor to a mad scientist, the robot is considered a "slave" to its "master" doctor, who controls the automaton's arms using two joysticks. The doctor is still in charge of the cuts, but the technology makes sure the MD jabs that needle in at the exact same entry point each time without shaking to minimize ocular marring. Another notable feature is the robot's ability to switch between tools quickly, ensuring that if this whole doctor thing doesn't work out, it'll at least have a job at Hibachi waiting.

AOptix e-Gate could improve global airport security, replace ID checks with iris scans
You're certainly not alone if you think that the current airport security process is far from ideal. AOptix hopes to streamline and speed up security procedures by replacing manual boarding pass and ID checks with a biometric kiosk called e-Gate. The new system, which verifies passenger identities by matching an iris scan with a boarding pass, just received (IATA) approval, and is currently being tested in three airports around the world. It's not as slick as a similar concept we saw earlier this summer, but e-Gate could be implemented with a trusted traveler program, creating special lanes for pre-approved frequent fliers -- similar to the US Customs Global Entry system in place today. We don't see it replacing X-ray machines and check-in interviews, but it could remove human error from the equation -- at least when it comes to verifying your identity. Jump past the break for the full scoop from AOptix, or you can check out the system for yourself at the Future Travel Experience in Vancouver. Update: e-Gate is in fact a potential component of Checkpoint of the Future, which we saw conceptualized in June.%Gallery-133007%
IATA's Checkpoint of the Future uses biometric IDs to separate do-gooders from terrorists (video)
This, ladies and gentlemen, could be your Checkpoint of the Future -- a new airport security prototype that promises to move away "from a system that looks for bad objects, to one that can find bad people." Unveiled at the IATA's annual conference in Singapore yesterday, the setup is comprised of three, 20-foot long detectors -- one for "known travelers," one for high-risk flyers, and one for everyone else. Instead of funneling passengers through the same checkpoint, then, the prototype would use eye scanners and biometric chips to verify their identities and analyze their personal history, before dividing them into groups. People who complete and pass government background checks would waltz through the fast pass lane with their carry-on luggage in tow, whereas those deemed particularly risky would have to undergo a more intensive, full-body scan within the "Enhanced" security lane. The rest of us, meanwhile, would be directed to the "Normal" detector, which would automatically scan us for liquids, metals and everything that is evil. The IATA says this risk-based approach would reduce security lines and lower airport costs, but it would still require governments to share data on their own citizens, which could pose a major hurdle to widespread adoption. For now, the IATA and governmental agencies are still hammering away at the details and have yet to announce a pilot program, but you can check out an audio-less demo video of the prototype, after the break.
Bionic eye closer to human trials with invention of implantable microchip
We've had our eye -- so to speak -- on Bionic Vision Australia (BVA) for sometime, and with the invention of a new implantable microchip it's coming ever closer to getting the bionic eye working on real-deal humans. The tiny chip measures five square millimeters and packs 98 electrodes that stimulate retinal cells to restore vision. Preliminary tests are already underway, and clinicians are in the process of screening human guinea pigs for sampling the implants -- the first full system is still on track for a 2013 debut. In the interest of future success: here's mud in your eye, BVA! Full PR after the break.
Researchers debut one-cubic-millimeter computer, want to stick it in your eye
This as-of-yet-unnamed mini computer was fashioned as an implantable eye pressure monitor for glaucoma patients, but its creators envision a future where we're all crawling with the little buggers. Taking up just over one cubic millimeter of space, the thing stuffs a pressure sensor, memory, thin-film battery, solar cell, wireless radio, and low-power microprocessor all into one very small translucent container. The processor behind this little guy uses an "extreme" sleep mode to keep it napping at 15-minute intervals and sucking up 5.3 nanowatts while awake, and its battery runs off 10 hours of indoor light or one and a half hours of sun beams. Using the sensor to measure eye pressure and the radio to communicate with an external reader, the system will continuously track the progress of glaucoma, without those pesky contacts. Of course, the mad scientists behind it look forward to a day when the tiny device will do much more, with each of us toting hundreds of the computer implants all over our bodies -- looks like a bright future for cyborgdom.
Visualized: the last glass eye maker in Britain
We'll be the first to admit that there's not a lot of tech in use here -- this is the story of a man using techniques that are hundreds of years old. Still, it's a mesmerizing glimpse into the creation of art with a hugely useful purpose: glass eyes. The video below is a study of Jost Haas, a Londoner who shapes each orb by hand, said to be the last man in Britain who still manufactures them this way. It's a 16mm film shot by Ben Todd and, if you like, you can consider this your five minutes and three seconds of zen for the day. Update: Loudmouthman was kind enough to share this link that contains another video of Mr. Haas in action plus some further information from one of the recipients of his work.
Nintendo 3DS warning label: children under six shouldn't use 3D mode
Ever since the device was first shown at E3, we've been under the impression that the Nintendo 3DS is too good to be true -- three-dimensional, portable versions of beloved N64 games? That's un-possible. The other shoe we've been waiting to drop might have just done so with Nintendo's recently released 3DS warning label; not only does it caution adults to stop using the device if they start to feel ill, it also says that children under six shouldn't use the handheld's 3D functionality at all, as it may affect the development of their poor, innocent eyes. This isn't quite as explosive a story as the mainstream media will likely make it out to be -- 3D display experts have long discussed the possible repercussions the technology has on eyesight. The worry isn't that displays like the one included in the 3DS will actually harm your vision, but that the way it "tricks" your eyes into seeing 3D might impair the way you actually see depth, which is, of course, the coolest dimension. Of course, there's no firm research confirming these worries, but Nintendo's playing it safe -- the 3DS' parental controls will allow parents to lock the device into 2D mode for their under-six progeny.
Artificial bee eye gives diminutive robotic air drones wider range of vision
We'd bother telling you up front that it also gives them a new sense of purpose, but you're already versed in how the impending Robot Apocalypse is going to go down. Wolfgang Stürzl and his best buds over at Bielefeld University in Germany have just published a report detailing how an artificial bee eye could improve the vision of miniature robots -- ones that fly, in particular. By using a catadioptric imaging system, which captures an image using both mirrors and lenses, they were able to utilize a single camera to capture a full 280-degrees of vision, and a lowly internal computer is able to stitch the two panes together in order to create a usable image that humans can interpret. The idea here is to provide more sight with less space, bringing us one step closer to actually having our very own 'fly-on-the-wall' moment. Comforting, no?
Eye-tracking lie detectors inch a little closer to reality
If lie detection is your thing, choices aren't exactly scarce: you can go with Lego for the kids, Skype-centric for remote fibber identification, or even use a headband if you can corral your suspect long enough. Hoping to add to that list is the University of Utah, whose eye-tracking lie detector has been licensed to a local company in order to explore its viability as a commercial product. As with Blade Runnner's Voight-Kampff empathy test, Utah's methodology revolves around monitoring things like eye movement, pupil dilation and response time -- with the major difference being that you're trying to identify truth evaders rather than skinjobs. John Kircher, one of the lead researchers, claims results so far have been as good as or better than those obtained with polygraph testing, though he admits the project is still in its early stages. No worries, though, we're sure they'll perfect the technique in time for our post-apocalyptic, Vangelis-scored future.
Amblyopic six-year-old uses Nintendo DS to regain normal eyesight
Ben Michaels was on the verge of losing sight in his right eye. The solution? Two hours of Mario Kart DS a day -- using only his bad eye -- until the condition improved. And improve it did. We wonder if using the comparatively dim original DS handheld helped... and we're dying to know what fantastic anecdotal treatments the autostereoscopic Nintendo 3DS might afford civilization at large.
Australian researchers unveil bionic eye prototype, implants coming in 2013
We've been hearing about things like bionic eyeballs -- specifically cameras which are implantable into human eyes -- for quite some time now. But it looks like Bionic Vision Australia has actually developed a real, working prototype. BVA, along with researchers at the University of New South Wales, have shown off their advanced prototype of the "eye," which boasts a pair of glasses mounted with a camera, a pocket-mounted CPU, and a wireless electrode chip which must be surgically implanted in the eye. The electrode chip has 98 electrodes which stimulates cells on the optical nerve, resulting in improved vision for those with vision problems resulting from optical nerve problems. Clinical trials are scheduled to begin later this year in Melbourne, with the hope that actual patients will be treated sometime in 2013. Kudos! The full press release is after the break.
Stem cell therapy restores British man's eyesight
Russell Turnbull, now 38, lost almost all the sight in his right eye after trying to break up a fight and being sprayed with ammonia 15 years ago. The result for him was what's known as Limbal Stem Cell Deficiency, which caused him great pain, the need for therapeutic treatment, and economic dependency. Good news for Russell is that he can put all that behind him now, after becoming one of the first recipients of a new stem cell grafting procedure, whereby healthy tissue from his left eye was implanted into his right and -- just like a video game medpack -- restored his vision to normal. For the moment, this treatment is limited to patients with at least one healthy eye, but given the pluripotent nature of stem cells, it is hoped that tissue from elsewhere in the body could one day be used to regenerate damaged parts, such as the cornea in this case. You may find further enlightenment in the video after the break.
Video: doctors implant tooth into eye, restore sight, creep everyone out
Osteo-odonto-keratoprosthesis. It's a real procedure that really does revive people's ability to see, yet we get the feeling that people will be more, um, excited about how it's done than why it's done. The seemingly Mary Shelley-inspired doctors extract a tooth from a blind person and drill a hole through it, where a prosthetic lens is placed, and the resulting macabre construction is implanted into the blind person's eye. The tooth is necessary as the body would reject an artificial base. It's not at all pretty, and it cannot repair every type of blindness, but it's still a major step forward. To hear from Sharron Thornton, the first American to have undergone the procedure, check the video after the break, but only if you can handle mildly graphic content -- you've been warned.

BrainPort lets you see with your tongue, might actually make it to market
We first saw the crazy BrainPort in 2006, but the intervening time hasn't been wasted by its developers, who've brought the quirky visual aid to the cusp of commercial viability. If you'll recall, the device translates signals from a head-mounted camera to electrical pulses that lightly zap your tongue in response to visual stimuli -- early results have shown people can regain a good bit of their spatial awareness and even read large writing. The next step is FDA approval, which is expected by year's end, meaning that the BrainPort could arrive as early as 2010. There is a steep entry fee though, with prices expected to begin at $10,000, but the very fact you'll be able to buy it is a milestone in our book. Edifying video after the break. [Thanks, Toy]
New FpsBrain pills claim to make your eyes see games better
Listen, we're not doctors. Obviously. If we were doctors, we probably wouldn't be blogging. We'd be off doing highly lucrative doctor stuff. Still, even without years of fancy doctor schoolin', we can assure you that taking pills of any sort won't make you better at playing video games -- even when those pills are the new gamer-oriented FpsBrain Zoom "visual performance" enhancing capsules.These meds are set apart from FpsBrain's other offerings, which contain enough caffeine and guarana to allow most toddlers to tap into the Speed Force. Instead of filling you with raw energy, Zoom allows you to actually see better during your lengthy Halo 3 sessions, providing you with the ocular edge that ... aw, screw it. Taking good care of your eyes is important, but ordering dubious pills from European countries probably isn't the best way to do so. We prefer carrots! They're crunchy, delicious and American.
British physics professor perfects "tunable eyeglasses" -- no eye doctor required
We've seen small scale liquid lenses progress from concepts to commerical applications, and now Joshua Silver, a retired physics professor at Oxford University, has perfected what he calls "adaptive glasses," applying similar tech in a singular and ingenious way. Aimed at helping developing nations where glasses are expensive and doctors are often in short supply, Silver's spectacles are made of tough plastic with with silicone liquid in the lenses. When purchased, each lense will have a syringe attached to it, and the wearer will be able to adjust the amount of liquid in the lenses -- which essentially changes the prescription -- without the need for an optician. About 10,000 pairs have been distributed in Ghana on a trial basis, with plans to distribute one million pairs in India in the next year -- the ultimate goal is one billion by 2020. And somewhere else in the world, a room full of opticians cry into their beer.
