      Retinal texture could provide early biomarker of Alzheimer's disease

      Biomedical engineers at Duke University have devised a new imaging device capable of measuring both the thickness and texture of the various layers of the retina at the back of the eye. The advance could be used to detect a biomarker of Alzheimer's disease, potentially offering a widespread early warning system for the disease. The results appear online on May 13 in the journal Scientific Reports . "Previous research has seen a thinning of the retina in Alzheimer's patients, but by adding a light-scattering technique to the measurement, we've found that the retinal nerve fiber layer is also ...

      Machine learning increases resolution of eye imaging technology

      Biomedical engineers at Duke University have devised a method for increasing the resolution of optical coherence tomography (OCT) down to a single micrometer in all directions, even in a living patient. The new technique, called optical coherence refraction tomography (OCRT), could improve medical images obtained in the multibillion-dollar OCT industry for medical fields ranging from cardiology to oncology. The results appear in a paper published online on August 19 in the journal Nature Photonics . "An historic issue with OCT is that the depth resolution is typically several times better than the lateral resolution," said Joseph Izatt, the Michael J. Fitzpatrick ...

      Handheld device takes high-resolution images of children's retinas

      Engineers and physicians at Duke University have developed a handheld device capable of capturing images of a retina with cellular resolution. The new probe will allow researchers to gather detailed structural information about the eyes of infants and toddlers for the first time. "Diagnostic tools that examine and image the retina have been well-designed for adults, but are exceedingly difficult to use in infants and young children who can't hold the required position or focus for long enough periods of time," said Cynthia Toth, professor of ophthalmology and biomedical engineering at Duke University. "Before now, it hasn't been ...
