Abstract:
In this article the authors discuss electronic and optogenetic approaches for degenerative (blind) retina prosthesis as the main strategies for the restoration of vision to blind people. Primary attention is devoted to the prospects of developing retinal prostheses for the blind using modern optogenetic methods, and rhodopsins, which are photosensitive retinal-binding proteins, are examined as potential tools for such prostheses. The authors consider the question of which particular cells of the degenerative retina for which rhodopsins can be prosthetic as well as ways of delivering the rhodopsin genes to these cells. In conclusion, the authors elucidate the main provisions and tasks related to optogenetic prosthetics for degenerative retina.

Abstract:
Artificial vision is restoring sight by electrical stimulation of the visual system at the level of retina, optic nerve, lateral geniculate body, or occipital cortex. The development of artificial vision began with occipital cortex prosthesis; however, retinal prosthesis has advanced faster in recent years. Currently, multiple efforts are focused on finding the optimal approach for restoring vision through an implantable retinal microelectrode array system. Retinal prostheses function by stimulating the inner retinal neurons that survive retinal degeneration. In these devices, the visual information, gathered by a light detector, is transformed into controlled patterns of electrical pulses, which are in turn delivered to the surviving retinal neurons by an electrode array. Retinal prostheses are classified based on where the stimulating array is implanted (ie, epiretinal, subretinal, suprachoroidal, or episcleral). Recent regulatory approval of 2 retinal prostheses has greatly escalated interest in the potential of these devices to treat blindness secondary to outer retinal degeneration. This review will focus on the technical and operational features and functional outcomes of clinically tested retinal prostheses. We will discuss the major barriers and some of the more promising solutions to improve the outcomes of restoring vision with electrical retinal stimulation.

Abstract:
Despite many advances in the development of retinal prostheses, clinical reports show that current retinal prosthesis subjects can only perceive prosthetic vision with poor visual acuity. A possible approach for improving visual acuity is to produce virtual electrodes (VEs) through electric field modulation. Generating controllable and localized VEs is a crucial factor in effectively improving the perceptive resolution of the retinal prostheses. In this paper, we aimed to design a microelectrode array (MEA) that can produce converged and controllable VEs by current steering stimulation strategies. Through computational modeling, we designed a three-dimensional concentric ring–disc MEA and evaluated its performance with different stimulation strategies. Our simulation results showed that electrode–retina distance (ERD) and inter-electrode distance (IED) can dramatically affect the distribution of electric field. Also the converged VEs could be produced when the parameters of the three-dimensional MEA were appropriately set. VE sites can be controlled by manipulating the proportion of current on each adjacent electrode in a current steering group (CSG). In addition, spatial localization of electrical stimulation can be greatly improved under quasi-monopolar (QMP) stimulation. This study may provide support for future application of VEs in epiretinal prosthesis for potentially increasing the visual acuity of prosthetic vision.

Abstract:
Age-related macular degeneration and retinitis pigmentosa are two of the most common diseases that cause degeneration in the outer retina, which can lead to several visual impairments up to blindness. Vision restoration is an important goal for which several different research approaches are currently being pursued. We are concerned with restoration via retinal prosthetic devices. Prostheses can be implemented intraocularly and extraocularly, which leads to different categories of devices. Cortical Prostheses and Optic Nerve Prostheses are examples of extraocular solutions while Epiretinal Prostheses and Subretinal Prostheses are examples of intraocular solutions. Some of the prostheses that are successfully implanted and tested in animals as well as humans can restore basic visual functions but still have limitations. This paper will give an overview of the current state of art of Retinal Prostheses and compare the advantages and limitations of each type. The purpose of this review is thus to summarize the current technologies and approaches used in developing Retinal Prostheses and therefore to lay a foundation for future designs and research directions.

Abstract:
This article reviews retinal prosthesis that is a seeing-eye chip with as many as 1000 tiny electrodes to be implanted in the eye. It has the potential to help people who have lost their sight regain enough vision to function independently in the sighted world. The Artificial Retina Project is a collaboration of five US National laboratories, three universities, and the private sector. The interface module and the antenna for future versions of the retinal prosthesis will all be implanted in the eye, instead of outside the eye. The retinal prosthesis will help patients who still have neutral wiring from the eye to the brain. One of the challenges in developing the device is creating a microelectrode array that conforms to the curved shape of the retina, without damaging the delicate retinal tissue. Oak Ridge National Laboratory in Oak Ridge, Tennessee, is the lead lab on the Artificial Retina Project. They're the folks responsible for fabricating and testing the electrodes, and making sure they're up to the challenge of being implanted long term in a human body.

Abstract:
This article describes how the field of vision prostheses is currently being developed around the world to restore useful vision for people suffering from retinal degenerative diseases. The vision prosthesis system (VPS) maps visual images to electrical pulses and stimulates the surviving healthy parts in the retina of the eye, i.e. ganglion cells, using electric pulses applied through an electrode array. The retinal neurons send visual information to the brain. This article presents the design of a prototype vision prosthesis system which converts images/video into biphasic electric stimulation pulses for the excitation of electrodes simulated by an LED array. The proposed prototype laboratory model has been developed for the design of flexible high-resolution 1024-electrode VPS, using an embedded computer-based efficient control algorithm for better visual prediction. The prototype design for the VPS is verified visually through a video display on an LCD/LED array. The experimental results of VPS are enumerated for the test objects, such as, palm, human face and large font characters. The results were found to be satisfactory.

Abstract:
The last few decades have witnessed an immense effort to develop working retinal implants for patients suffering from retinal degeneration diseases such as retinitis pigmentosa. However, it is becoming apparent that this approach is unable to restore levels of vision that will be sufficient to offer significant improvement in the quality of life of patients. Herein, a new type of retinal prosthesis that is based on genetic expression of microbial light sensitive ion channel, Chanelrhodopsin-2 (ChR2), and a remote light stimulation is examined. First, the dynamics of the ChR2 stimulation is characterized and it is shown that (1) the temporal resolution of ChR2-evoked spiking is limited by a continuous drop in its depolarization efficiency that is due to (a) frequency-independent desensitization process and (b) slow photocurrent shutting, which leads to a frequency-dependent post-spike depolarization and (2) the ChR2 response to light can be accurately reproduced by a four-state model consisting of two interconnected branches of open and close states. Then, a stimulation prototype is developed and its functionality is demonstrated in-vitro. The prototype uses a new micro-emissive matrix which enables generating of two-dimensional stimulation patterns with enhanced resolution compared to the conventional retinal implants. Finally, based on the micro-emitters matrix, a new technique for sub-cellular and network-level neuroscience experimentations is shown. The capacity to excite sub-cellular compartments is demonstrated and an example utility to fast map variability in dendrites conductance is shown. The outcomes of this thesis present an outline and a first proof-of-concept for a future photogenetic retinal prosthesis. In addition, they provide the emerging optogenetic technology with a detailed analysis of its temporal resolution and a tool to expand its spatial resolution, which can have immediate high impact applications in modulating the activity of sub-cellular compartments, mapping neuronal networks and studying synchrony and plasticity effects.

Abstract:
Retinal prostheses require the presence of viable population of cells in the inner retina. Evaluations of retina with Age-Related Macular Degeneration (AMD) and Retinitis Pigmentosa (RP) have shown a large number of cells remain in the inner retina compared with the outer retina. Therefore, vision loss caused by AMD and RP is potentially treatable with retinal prostheses. Photostimulation based retinal prostheses have shown many advantages compared with retinal implants. In contrary to electrode based stimulation, light does not require mechanical contact. Therefore, the system can be completely external and does not have the power and degradation problems of implanted devices. In addition, the stimulating point is flexible and does not require a prior decision on the stimulation location. Furthermore, a beam of light can be projected on tissue with both temporal and spatial precision. This thesis aims at finding a feasible solution to such a system. Firstly, a prototype of an optoelectronic stimulator was proposed and implemented by using the Xilinx Virtex-4 FPGA evaluation board. The platform was used to demonstrate the possibility of photostimulation of the photosensitized neurons. Meanwhile, with the aim of developing a portable retinal prosthesis, a system on chip (SoC) architecture was proposed and a wide tuning range sinusoidal voltage-controlled oscillator (VCO) which is the pivotal component of the system was designed. The VCO is based on a new designed Complementary Metal Oxide Semiconductor (CMOS) Operational Transconductance Amplifier (OTA) which achieves a good linearity over a wide tuning range. Both the OTA and the VCO were fabricated in the AMS0.35 μm CMOS process. Finally a 9X9 CMOS image sensor with spiking pixels was designed. Each pixel acts as an independent oscillator whose frequency is controlled by the incident light intensity. The sensor was fabricated in the AMS 0.35 μm CMOS Opto Process. Experimental validation and measured results are provided.

Long-term success of an implantable retinal prosthesis depends on the ability to hermetically seal sensitive electronics from a saline environment with an encapsulant material. Furthermore, the retinal implant project's proposed laser-driven prosthesis requires that the encapsulation material be transparent. The device itself has two components that must protrude out of the encapsulation material. The first is an electrode array on a polyimide strip. The second is a platinum return wire. Difficulty in finding encapsulation materials has arisen from saline leakage at the interface of the encapsulant and these two protruding components. This thesis addresses the pursuit of materials and bonding strategies suitable to protect the device in chronic submersion. An electrode array lying on a polyimide layer sits flat against the ganglion cells within the eye. Precise stimulation requires that current does not flow between the individual electrode contacts. The array must be tested under chronic saline submersion to ensure that each electrode remains electrically isolated by the polyimide. The electronics package will be supported in the eye by a modified intraocular platform, similar to a device typically used in human cataract surgery. The lens is created by photolithography, a rapid prototyping technique. This platform must conform to surgical needs and structural integrity required by the device. The primary goal of this thesis is to find a flexible transparent encapsulant material. This material must undergo long term leakage tests to ensure that it will be reliable in protecting the microelectronics mounted on the platform before being considered for use. The secondary goal of the thesis is testing of the polyimide electrode array itself to determine its ability to resist saline leaks.

This work was undertaken to contribute to the development of an epi-retinal prosthesis which may someday restore vision to patients blinded by outer retinal degenerations like retinitis pigmentosa. By stimulating surviving cells in tens or hundreds of distinct regions across the retinal surface, the prosthesis might convey the visual scene in the same way that images are represented on a computer screen. The anatomical and functional arrangement of retinal neurons, however, poses a potential obstacle to the success of this approach. Stimulation of ganglion cell axons-which lie in the optic nerve fiber layer between stimulating electrodes and their intended targets, and which originate from a relatively diffuse peripheral region-would probably convey the perception of a peripheral blur, detracting from the usefulness of the imagery. Inspired by related findings in brain and peripheral nerve stimulation, experiments were performed in the isolated rabbit retina to determine if excitation thresholds for ganglion cell axons could be raised by orienting the stimulating electric field perpendicularly to the axons' path. Using a custom-designed apparatus, axon (and possibly dendrite) thresholds were measured for stimulation through a micro-fabricated array of disk electrodes each having a diameter of ten microns. The electrodes were driven singly versus a distant return (monopolar stimulation) and in pairs (bipolar stimulation) oriented along fibers (longitudinal orientation) or across fibers (transverse orientation). Transverse thresholds were measured for a range of fiber displacements between the two poles of the bipolar electrode pair, and compared in each case with the monopolar threshold for the closer pole. Transverse/ monopolar threshold ratios were near unity when one of the poles was directly over the fiber, but rose rapidly with improved centering of the bipolar pair. Longitudinal/monopolar threshold ratios were near unity over the same range of displacements. As in previous work by others, thresholds were highest for perpendicular stimulating fields. Practical application of this result will require electrode designs which minimize longitudinal fringing fields.

Abstract:
Developing artificial visual systems to restore sight in blind patients has long been the dream of scientists, clinicians and the public at large. After decades of research, the greatest success in the field has been achieved with electronic retinal prostheses. To date, 3 retinal prosthetic systems have made the transition from laboratory / clinical research to entering the commercial market for clinical use, namely the Argus® II Retinal Prosthesis System (Second Sight), the alpha-IMS system (Retinal Implant AG), and the IRIS® II (Pixium Vision). The following body of work describes the Argus® II Retinal Prosthesis system, which obtained regulatory approval in the European Economic Area in 2011 (CE marking) and later on in the USA (FDA approval in February 2013), based on the results of an international multi-centre clinical feasibility trial (Clinical Trial identifier: NCT 00407602). This thesis aims to examine the long-term clinical and functional outcomes in an early cohort of subjects chronically implanted with the Argus® II system, from the original feasibility study. A further aim is to elucidate the characteristics of the artificial vision that is perceived and its long-term repeatability and reproducibility in individual subjects. These two broad aims will assist in understanding the nature of the visual performance provided by this device, as well as to add to the current data that is defining the feasibility of constructing predictable pixelated patterns to achieve useful artificial vision in the future. Finally, we explored the feasibility of real-time imaging of visual cortex activation in response to electrical retinal stimulation with the Argus® II system, using functional near infra-red spectroscopy (fNIRS). Development of this real-time imaging tool will enable future investigations into the differences in the cortical activities in response to different stimulations and in different subjects. This may in turn help us understand the variability in their visual performance, as well as to further explore the extent and effect of cross-modal plasticity at the cortical level, in this cohort of patients who have been deprived of visual inputs for decades. Visual function was assessed in terms of: a) form recognition and b) spatial localisation under both 2-dimensional (2D) screen-based laboratory settings and 3-dimensional (3D) paradigms simulating real-life settings. A prospective study of 11 Argus® II subjects showed that the subjects could identify distinct geometric shapes presented in high contrast better with the prosthetic system switched on (median % of correct identification = 20.0%, IQR = 18.8), versus off (median = 12.5%, IQR = 5.0). The accuracy of shapes identification could be further improved by enhancing the outlines of the geometric shape (median = 33.1%, IQR = 21.6). A further prospective study from a subset of 7 subjects showed that this 2D shape identification could be translated into improved identification of 3D objects. These subjects could identify 8 common daily-life objects presented in high contrast with the prosthetic system switched on (median = 31.3%, IQR = 20.3) versus off (median = 12.5%, IQR = 12.5). Scrambling of the transmission signals within the prosthetic system in order to separate light information from form information (i.e. “scrambled mode”) hindered the identification in some but not all subjects (median = 25.0%, IQR = 12.5). The accuracy of object identification could also be improved by enhancing the edges of objects (median = 43.8%, IQR = 15.6). Previously published data showed that Argus® II subjects were able to locate and point to white squares presented on touch screens against a black background more accurately with the prosthetic system switched on versus off. We demonstrated with a prospective study of 5 subjects that they could localise an object on the table, reach out and grasp the object (prehension) with great accuracy (66.7 – 100%) when the prosthetic system was switched on, versus no object prehension (0%) with the system switched off. A prospective study of 6 Argus® II subjects illustrated that while there was a wide variation in the shape and size of the phosphenes perceived by individual subjects, the elicited phosphenes were consistently reproducible in each subject using fixed stimulating parameters, with inter-stimuli intervals ranging from 20 minutes apart, down to 1 second. The perceived location of the phosphenes grossly matched retinotopic agreement, with 4 subjects drawing phosphenes in the same visual field quadrant as predicted by the relative stimulus-fovea position, and 2 subjects depicting phosphenes in the same hemi-field as the expected locations. A retrospective study of 3 Argus® II subjects who underwent MRI brain scan (for unrelated medical reasons) showed that MRI brain scans of up to 1.5 Tesla field strength appeared to have no detrimental effect on the subjects and their implant function. The Argus® II implant produced an artefact of around 50mm x 50mm in size which would prevent visualisation of structures within the orbit, but visualisation of surrounding tissues outside this areas are unaffected. The use of functional MRI as a tool of exploring visual cortex activation in Argus® II subjects was discounted, due to concerns of signal interference from the radiofrequency telemetry of Argus® II system with that of MRI. Subsequently, we have demonstrated in a prospective study that an alternative neuro-imaging technique, functional near infra-red spectroscopy (fNIRS), was capable of capturing real-time cortical activation in 5 out of 6 Argus® II subjects, and maybe a feasible tool for future investigation into cortical function and interactions. The work in this thesis has shown that the Argus® II retinal prosthesis system could improve visual function both in terms of form recognition, as well as object localisation in 3D in situations simulating real-life settings, in a cohort of patients with end-stage retinitis pigmentosa or other outer retinal diseases such as choroideremia. The wide variation in the visual performance level observed could in part be attributable to the diversity in the phosphene features perceived by these subjects. Nevertheless, the consistency and reproducibility with which these phosphenes could be elicited, with fixed stimulating parameters within each subject, provides an encouraging basis for the construction of more complicated pixelated images. Future work to determine the underlying factors influencing the perceived phosphene characteristics, may allow for better prediction of functional outcome, which could in turn be useful for patient selection and tailored preoperative counselling. For those subjects already implanted with the Argus® II system, future work into determining the suitable stimulating parameters for each electrode / quad stimulation may be required for individual subjects, to achieve the construction of optimised and useful, pixelated prosthetic vision.

Abstract:
Restoring vision to the blind has been an objective of several research teams for a number of years. It is known that spots of light -- phosphenes -- can be elicited by way of electrical stimulation of surviving retinal neurons. Beyond this, however, our understanding of prosthetic vision remains rudimentary. To advance the realisation of a clinically viable prosthesis for the blind, a versatile integrated circuit neurostimulator was designed, manufactured, and verified. The neurostimulator provides electrical stimuli to surviving neurons in the visual pathway, affording blind patients some form of patterned vision; besides other benefits (independence), this limited vision would let patients distinguish between day and night (resetting their circadian rhythm). This thesis presents the development of the neurostimulator, an interdisciplinary work bridging engineering and medicine. Features of the neurostimulator include: high-voltage CMOS transistors in key circuits, to prevent voltage compliance issues due to an unknown or changing combined tissue and electrode/tissue interface impedance; simultaneous stimulation using current sources and sinks, with return electrodes configured to provide maximum charge containment at each stimulation site; stimuli delivered to a two dimensional mosaic of hexagonally packed electrodes, multiplexing current sources and sinks to allow each electrode in the whole mosaic to become a stimulation site; electrode shorting to remove excess charge accumulated during each stimulation phase. Detailed electrical testing and characterisation verified that the neurostimulator performed as specified, and comparable to, or better than, other vision prostheses neurostimulators. In addition, results from several animal experiments verified that the neurostimulator can elicit electrically evoked visual responses. The features of the neurostimulator enable research into how simultaneous electrical stimulation affects the visual neural pathways; those research results could impact other neural prosthetics research and devices.
