Quick eye check with handheld scanner

Busy periods do not have periodic eye examinations or intermittent eye examinations at clinics or hospitals can cause many people to experience eye problems when it is too late. That's why researchers at the Massachusetts Institute of Technology (MIT) have developed compact retina scanners that help people check their eyes anytime, anywhere.

Unlike bulky equipment used by ophthalmologists, the new product is about the size of a small camcorder. It takes advantage of the current technology called optical tomography (OTC) , which emits infrared light on the retina and evaluates the light reflecting signals to produce a 3D image of the retina.

The special feature is that the device can scan each part of the retina from different directions at the same time to avoid blurring of images during use. With a mixture of three-dimensional images created, the scanner takes just seconds to "read" and find the risk of glaucoma, macular degeneration, or diabetic retinopathy.

It is known that two versions of the scanner were tested in the laboratory with accurate results similar to the traditional OCT scanner. It is hoped that this device, after refinement and improvement to lower production costs, is not only suitable for use in ophthalmic clinics but can also be widely used in developing countries.
