New Smartphone Accessory Can Take High-Resolution Images Deep Inside The Eye
Smartphones are substantially playing effective role in medical sciences. Different apps and accessories have been introduced to perform different health-related functions. One such invention is called Mobilevision which is capable to capture one of the most sensitive parts of human eye from with in.
The researchers team that is working on this revolutionary instrument for health care belongs to the Rice University. The team went to the eye specialists in order to ask what actually they needed most in curing eyes. The most frequent response from the doctors was: “Can you image the macula?” And this probably motivated them to present the doctors with the gift of a smartphone peripheral Mobilevision, which can really image macula, which is very sensitive part of the eye and is responsible for complete central vision.
“Whatever you look directly at you see in very high resolution, while your peripheral vision is blurry,” research team member Ashok Veeraraghavan, who is an assistant professor of electrical and computer engineering said. “The region of the retina that provides you with this high resolution is the macula. And degradation of the macula immediately affects your eyesight.”
Such an innovation will be a blessing especially for those who are patients of diabetes and other similar diseases that can degenerate the eye. These issues lead to snowball, so to avoid the worst, such patients’ eyes are consistently examined via scans etc.
The scanning process is not as simple as it may sound. In fact, it is always a source of discomfort for most of the patients. This is because scans not only require dilation of eyes with drugs for better imaging, they also need a patient to visit typical place where the scanning instrument is available — which is indeed a tough discipline for patients to follow every time.
With the arrival of the new smartphone accessory, this discomfort and stringent discipline is no more required from the patients. The instrument, however, needs to be designed as a super fast and accurate machine. Because it has to take the images of macula before even the one contraction of the eye pupil without losing precision and accuracy.
The instrument being discussed has the capabilities whatever it may take to image macula. Along with the required speed and accuracy, it offers patients an excellent feasibility. That is, they can perform these scans themselves at any place.
Check out the video below showing how the instrument works.
Firstly a large red disk is shown to the patient when he looks into the eyepiece. The patient needs to align the disk with his eye which he can easily determine by observing the appearance of disk — it will become perfectly bright after proper adjustment.
“That dark target induces pupil dilation naturally,” a researcher said. “When you present the eye with a stimulus that isn’t throwing a lot of photons at it, the eye dilates to collect more light and have a better look.”
Then by pressing the trigger, more than 10 images of the retina will be taken. The better one can be selected by the patient to send to the ophthalmologist for detailed analysis.
The team presented the first comprehensive results of their work at the Wireless Health 2014 conference in Bethesda, MD, in October 2014. It’s not known if this particular gadget has been commercialized since, but what is known is that it will bring a great advancement in the field of ophthalmology, and a couple of such devices may revolutionize the medical diagnostics.
