is selfie that could save your eyes. An embedded sensor that can help people with glaucoma in the eye pressure monitor them using the smartphone's camera.
Glaucoma occurs when fluid builds up in the eye. and this could exert pressure on the eye, damaging the optic nerve. Accurate pressure is very important to provide treatment, but one-off measurements during check-ups produce variable results and can be misleading.
Mandel Yossi Bar-Ilan University in Ramat Gan, Israel, and his colleagues have developed a pressure sensor that can be inserted into the eye during surgery to provide an easy, routine monitoring of the home.
A few millimeters in length, the sensors can be implanted into a synthetic lens used to replace the natural lens with cataract. He also works as a miniature barometer, and increased fluid that contains a column with the eye pressure. The level can be read at any time by using the smartphone camera is equipped with a special optical adapter. Software then analyzes the image and calculate readings.
Some eye pressure probes have been developed since the early 1990s. This includes contact lenses made by Sensimed, based in Lausanne, Switzerland, which can estimate the eye pressure is based on how the cornea bends. Sensimed sensor is the only device wearable pressure available commercially, but are intended for short-term use only. Mandel said that the sensor can be mounted in the eyes of patients over the years.
Synthetic lens implant containing a sensor would require invasive surgery, something that is only suitable for patients who need new lenses as well as cataracts.
