Artificial retinas have the potential to restore some sight to people with certain kinds of blindness, but they contain complex electronics that can overheat. Now a Stanford team has found a way to potentially bypass the issue.

The Injectsense implant is designed to constantly monitor a glaucoma patient's intraocular pressure, transmitting readings to the cloud.

A new device has been designed to improve diagnosis of dry eye disease, perhaps also leading to more effective treatments.

An app designed to detect early signs of several eye diseases has surpassed an 80 percent accuracy rate, equaling the sensitivity of devices used by trained ophthalmologists.

A study reveals measuring the speed of pupil dilation while undertaking a cognitive test could help identify early, pre-symptomatic stages of Alzheimer’s.

Two new autism detection methods are promising to offer clinicians objective diagnostic tools that are not based on subjective behavioral assessments. Both systems are in early stages of clinical verification but they enter a busy field of research into autism biomarkers.

​Despite the fact that dry eye disease (DED) is a relatively common condition, there are relatively few drugs approved for its treatment. This is because the testing of such medications on actual human eyes would be quite risky. With that in mind, scientists have developed a blinking eye-on-a-chip.

​There are already a number of inexpensive new devices that allow doctors in developing nations to image patients' retinas. In order to get a better look at what's going on, though, an optical coherence tomography (OCT) scanner is required – and a cheaper one of those has now also been developed.

Presbyopia is a common form of age-induced far-sightedness. Now a Stanford team has developed a pair of high-tech specs called autofocals, which use fluid-filled lenses, depth-sensing cameras and eye-tracking technology to make sure whatever a wearer is looking at stays sharp.

​In remote communities, a family doctor may or may not be present, but an ophthalmologist likely isn't. That's why Brazilian startup Phelcom Technologies created the Eyer, a smartphone-connected device that allows patients' retinal-scan images to be analyzed by ophthalmologists via the internet.

The subjective sense that time moves faster as we get older is a universal one, and over the years​ scientists have proffered a number of different explanations as to why this happens. A new and strange hypothesis attempts to explain the phenomena, and it has to do with our aging brains.

​Caused by autoimmune diseases, chemical burns, or sometimes even as a side effect of eye surgery, corneal melting is an incurable disease that's a major cause of blindness. It could someday be treated using a contact lens, however, which is currently in the works.
