Due to technical advances, there has been an enormous improvement of electronic vision aids in recent years. New developments are especially small portable devices which can be easily carried. The majority of electronic vision aids serve as a reading aid. Electronic magnifiers are a portable alternative to conventional screen readers. In addition, there are mobile reading devices and special computer tools. Color recognition devices and barcode scanners are helpful in everyday life. Ultrasonic orientation systems enable the recognition of obstacles also at head height. Mechanisms incorporated in shoes even comprise a navigation system. A brand new development is OrCam (OrCam Technologies Ltd., Israel), a small, inconspicuous camera system which is attached to the spectacles. It transmits vision information as a text. Smart phones and tablet personal computers have meanwhile been developed to such an extent that they replace more expensive special vision aids. Due to the immense technical progress, electronic vision aids provide visually impaired people with many elegant functions and new possibilities for ophthalmological rehabilitation. Besides the technical, mobile and financial aspects, the social acceptance of the devices, which should be as unobtrusive as possible, plays an essential role.

By a combination of averaged images of the vitreoretinal interface with the help of conventional SD-OCT scans with EDI OCT scans the FDI mode exhibits a simultaneous contrast image of the posterior vitreous, the retina and the choroid. Whereas the application of OCT was focused to evaluate the retina-retinal pigment epithel complex, the routine reinforcement of FDI scans could additionally show potential vitreous and choroidal pathologies. As the FDI mode is not an automated application yet it may be too complex to use for routine diagnostics at the moment.

With respect to the increasing number of patients and the risk and burden for patients caused by injections, a reduction in the number and frequency of injections with vascular endothelial growth factor (VEGF) inhibitors in exudative age-related macular degeneration (ARMD) is desirable. Stereotactic low-voltage x-ray irradiation seems to be a promising approach. For this purpose the Oraya system is available and has shown positive results in initial studies. Pending presentation of phase II and III study data this adjuvant irradiation should only be used in clinical trials.
