Is there any kind of mobile device which can provide high-quality images of the macula without dilation during the eye exam?

    Currently, there is a kind of new device called mobileVision, looks and works something like a reverse microscope.The device can take finely detailed images of the macula, the spot in the center of the eye where vision is sharpest, without artificially dilating the pupil. Those images can then be sent by cellphone to ophthalmologists who can make a diagnosis remotely.A patient looks into the eyepiece and sees a large dark red disk. When the system is shifted around freely, the appearance of the disk changes dramatically-appearing brightest and most uniform when perfectly aligned with the patient's eye.When this happens, the patient hits a button that moves the target out of the way and allows the camera to see into the eye, with help from a battery-powered light source.That dark target induces pupil dilation naturally.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. When the patient can clearly see the disk, the pupil is dilated and the system is aligned.Once the retina is illuminated. We have a window of only a few hundred milliseconds to snap as many frames as we can before the pupil constricts again.At that point, the patient's job is done. In an ideal situation, a mobile clinic anywhere in the world could use multiple mobileVision systems to gather data from many patients very quickly.

    Of course there is. That is mobilevision. A smart and simple method developed at Rice Univ. to image a patient's eye could help monitor eye health and spot signs of macular degeneration and diabetic retinopathy, especially in developing nations.The mobileVision is patient-operated and portable device. It can be paired 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 artificially dilating the pupil. Those images are then sent by cellphone to ophthalmologists who can make their diagnoses from afar.
