Portable, Patient-Operated Imaging System Could Help Doctors Diagnose Eye Health

A simple method to image a patient's eye developed at Rice University could help diagnose eye health and spot signs of macular degeneration and diabetic retinopathy. Generally, doctors have to dilate a patient's eyes - an uncomfortable, time-consuming process - before an exam that can involve expensive equipment. The new patient-operated, portable device is called mobileVision and it looks and works something like a reverse microscope. It pairs with a smartphone to give clinicians finely detailed images of the macula, the spot in the center of the eye where vision is sharpest, without dilation. Those images are then sent by phone to ophthalmologists who can make their diagnoses from afar.

    00:00:00 [Music] we are part of the mobile Vision team from Rice University and it's unfortunate but most people don't know that diabetes is the largest cause of blindness in the United States 80% of all people who have diabetes at one point or later will eventually develop diabetic retinopathy and many of them eventually go

    00:00:27 blind the recommendation of doctor as opthalmologist is to is for diabetic patients to get their retina screened once every 3 to 6 months or so the opthalmologist and optometras we've seen have told us numerous stories of patients coming in after years of not having been diagnosed with retinas that are really in bad shape we in the mobile Vision team at R University we're

    00:00:52 building a solution uh device mobile Vision that can help patients take images of Their Own retinas the images are directly sent to the opthalmologist to the doctors to their own pcps and can then be diagnosed by the doctors themselves this is the mobile Vision device the the latest prototype we have um and there's kind of a lot going on here but what what's happening is that

    00:01:19 I'm going to put this up against my my eye here and it'll sense when my eye is close enough um and it'll also let me figure out um how to adjust it such that it's properly aligned and right now the imag is going to be taken by this which is a camera that's mounted to a computer here um but there's no reason that this can't be replaced with a phone and that's our our sort of next step in the

    00:01:43 uh iteration of this prototype so I'll go ahead and show you what it looks like um let me go turn it on here all right so first step is to get it close enough to your face um and like I said it'll sense that by that little switch here so once it's close enough then I'm actually able to press the trigger button and so if I get aligned here going to press the trigger and

    00:02:12 that's it so in the time that that went out and went back in about 10 or so images of my retina have been taken um and with those we can do processing on them to kind of increase the quality of the retinal images you can see scalable health initiative is now around 4 years old uh initiative we started collaboratively with some faculty members students and our friends at

    00:02:38 Texas Medical Center it's been organically growing as we start to address more and more medical problems um so our driving goal is uh addressing uh building Technologies both for health care and wellness that can scale up to hundreds and thousands of millions of users quickly and that has been produc see results mobile vision is a great example U with that mindset and

    00:03:05 quite a few other projects are in pipeline which we expect to come out in coming [Music] years
