    摘要： An artificial retina device and a method for stimulating and modulating its function is disclosed. The artificial retina device is comprised of plural multi-phasic microphotodiode subunits. In persons suffering from blindness due to outer retinal layer damage, a plurality of such devices, when surgically implanted into the subretinal space, may allow useful formed artificial vision to develop. One device, called a MMRI-4, transduces light into electric currents to stimulate the retina. The four microphotodiode subunits of the MMRI-4 are oriented so that each flattened sides of the MMRI-4 has two subunits in a PiN configuration and two subunits in a NiP configuration. By projecting real or computer controlled visible light images, and computer controlled infrared light images or illumination, simultaneously or in rapid alternation onto the MMRI-4s, the nature of induced retinal images may be modulated and improved. An Adaptive Imaging Retinal Stimulation System (AIRES), with a Projection and Tracking Optical System (PTOS), which may be worn as a headset is used for this purpose, and is also disclosed. Color images may even be induced by programming the stimulating pulse durations and frequencies of the AIRES system.

    摘要： Mechanically activated objects or devices for use in treating degenerative retinal diseases are provided. Such devices apply mechanical forces to tissues of an eye to effectuate treatment and are configured for chronic implantation (thereby applying chronic stimulation/irritation) in or on the eye. The devices may be configured for contact with a retina of the eye, preferably positioned in a subretinal space. Various embodiments comprise a moving member configured for chronic contact with at least a portion of the eye, which moving member is activated by an actuator. In some embodiments, the actuator may be distally located relative to the moving member. Alternatively, the moving member may be supported by a body member that, optionally, also supports the actuator.

    摘要： Microscopic photoelectric devices with semitransparent surface electrodes are combined with a liquid or other suitable vehicle. Together they are injected into the subretinal space of the eye. The microscopic photoelectric devices transduce incident light into electric current that will stimulate the overlying cellular layers of the retina. In persons suffering from visual disfunction due to outer retinal layer damage, such devices may allow useful formed artificial vision. The preferred independent surface electrode microphotodiodes (ISEMCP's) may be in the shape of microspheres, microdiscs or other microshapes. The ISEMCP's are formed of either PiN or NiP type semiconductors, or a combination of both, in a single unit. These devices will form a dipole when exposed to light due to the electric current generated. A magnetic field applied in the vicinity of the eye may help align the ISEMCP's within the retina so that their photo-active surfaces face the incident light. Alternatively, the ISEMCP's may be embedded and prealigned in a transparent flexible sheet, permeable to nutrients and oxygen, before implantation into the subretinal space. Such sheet will allow passage of biological nutrients and oxygen around the ISEMCP's. This sheet may also dissolve leaving behind ISEMCP units lying separately, or in an arranged pattern produced by a surrounding mesh.
