Eye Health Prevention and Technology: How Far Are We?
Eye to eye. It seems like a play on words, but it perfectly expresses the concept of the attention we must have for ocular health, too often forgotten and severely tested by our habits, starting from the hours spent in front of smartphones and tablets to get to good habits .
The goal is not only to prevent classic vision defects such as myopia, but also to anticipate cataracts, macular degeneration and glaucoma. To "mark the way" in the context of SaluTO – Medicine and Wellness, Saturday 26 September at 19.30 in live streaming, there are Michele Reibaldi, full professor of Ophthalmology at the University of Turin and Eros Pasero, professor of Electronics, Department of Electronics and Telecommunications of the Politecnico di Torino. Because in the future, technology will help those with severe eye conditions.
The bionic eye? It is far!
An artificial organ for sight. A dream? At the moment, yes, although headlines such as "transplanted an artificial eye to a patient who begins to see lights and shadows" often appear in the newspapers. "It is not true and it is not right to deceive the blind" – Pasero specifies. We are very far from the technological eye.
In May, a research by the University of Hong Kong on an artificial eye with potential even higher than the human eye was published in the famous journal Nature. But how do I connect it to the brain that has to use it? This is the real problem, very far from the solution ”.
This does not mean that research is stopped. On the contrary, even if we are very far from a system of interconnection with the brain. “As early as the 1990s, a Japanese scientist, Fukushima, provided a model of an artificial retina which led to the use of the first human neuron model, described by Mc Culloch and Pitts in 1943, to develop a model of the retina. – resumes the expert. But we are talking about models, far from an artificial eye. And the question of how to use it always remains. Carver Mead at Caltech developed an artificial retina on silicon many years ago. Excellent circuit to connect to a computer, but unfortunately not to the brain. No doubt we will sooner or later reconstruct every part of the human body in bionic form. In the case of the transplantable eye, perhaps more then than before.
There are already electronic "readers" who read and speak. This is within our reach. But the transplant artificial eye is far away. And I repeat we must not deceive people who already suffer and could delude themselves. So no media sensationalism and we wait ”.
