A new digital ophthalmoscope, devised by a research team led by the University of Warwick can provide both doctors and high street optometrists with a hand held eye disease diagnosis device equal to the power of bulky hospital based eye diagnosis cameras. It will also give optometrists the ability to email detailed eye maps of patients to specialist eye doctors.

Advances in digital electronic circuits have prompted the boost in functions and ever- smaller size of such popular consumer goods as digital cameras, MP3 players and digital televisions. But the same cannot be said of the older analog circuits in the same devices, which process natural sights and sounds in the real world. Because analog circuits haven't enjoyed a similar rate of progress, they are draining power and causing other bottlenecks in improved consumer electronic devices.
