Eye implant measures pressure, releases fluid, in glaucoma

Caltech’s Azita Emami, Aubrey Shapero, Abhinav Agarwal and colleagues have developed a miniaturized, fully wireless, highly-sensitive, implantable, continuous pressure sensor that can remain in the human eye for four years.  The goal is early detection and treatment of glaucoma progression. Current tonometer measurement, which requires anesthesia, only measures pressure during an appointment, and can miss […]

Direct brain path for sight, sound via implanted microscope

Rice University’s Jacob Robinson, with Yale and Columbia colleagues, are developing FlatScope — a flat, brain implanted microscope that monitors and triggers neurons which are modified to be fluorescent when active. While capturing greater detail than current brain probes, the microscope also goes through deep levels that illustrate  sensory input processing — which they hope to […]

Less invasive, soft tissue artificial retina

Oxford University student Vanessa Restrepo-Schild is developing a synthetic, soft tissue retina that more closely resembles human tissue than current artificial retina technology. Unlike existing implants, the cell-cultures are created from natural, biodegradable materials and do not contain foreign bodies or living entities. This makes the implant less invasive than a mechanical device, and less […]

Transparent, stretchable lens sensor for diabetes, glaucoma detection

UNIST professors Jang-Ung Park, Chang Young Lee and Franklin Bien, and KNU professors Hong Kyun Kim and Kwi-Hyun Bae, have developed a contact lens sensor to monitor biomarkers for intraocular pressure, diabetes mellitus, and other health conditions. Several attempts have been  made to monitor diabetes via glucose in tears.  The challenge has been poor wearability, as the electrodes […]

Diabetic retinopathy-detecting algorithm for remote diagnosis

Google has developed an algorithm which it claims is capable of detecting diabetic retinopathy in photographs.  The goal is to improve the quality and availability of screening for, and early detection of,  the common and debilitating condition. Typically, highly trained specialists are required to examine photos, to detect the lesions that indicate bleeding and fluid […]

Eye tracking + VR to improve brain injury diagnosis, track recovery

Eye tracking technology, combined with VR, is proliferating, with myriad medical, gaming, and education applications. SyncThink uses eye tracking, built into an Oculus Rift,  to detect if a person has the ability to keep the eyes synced with moving objects, to determine brain injury and track recovery. The company has been granted 10 patents, for  eye-tracking hardware, and […]
