At the ASRS 31st Annual Meeting, Mark S. Humayun, MD, PhD, presented updated safety and performance results of the Argus® II Retinal Prosthesis System clinical trial and gave an overview of the commercial experience in Europe.. As of December 1, 2012, 30 subjects have been implanted at centers in the main study. This is the largest study of a visual prosthesis to date, with more than 125 cumulative patient-years of follow-up.. Results show the Argus II prosthesis provides visual function to patients with end-stage retinitis pigmentosa. Research has demonstrated visual acuity as high as 1.0 logMAR (20/200) and color perception. A total of 54 clinical trial subjects and commercial patients worldwide have received the Argus II implant.. The Argus II Retinal Prosthesis System has been commercially available in Europe since 2011 and received US Food and Drug Administration (FDA) approval in February 2013. As of October 1, 2013, the Argus II system has been approved for Medicare coverage. Software ...

Argus® II Retinal Prosthesis System is the first approved bionic eye in the US with life-changing potential for the treatment of blindness due to retinitis pigmentosa. SYLMAR, CA, 14 February 2013 After more than 20 years of research and development, Second Sight Medical Products, Inc., the leading developer of retinal prostheses for the blind, is pleased to announce that its Argus® II Retinal Prosthesis System (Argus II) has received U.S. market approval from the Food and Drug Administration (FDA) to treat individuals with late stage retinitis pigmentosa (RP). This announcement follows receipt of the European approval in 2011, and a unanimous recommendation by the FDAs Ophthalmic Devices Advisory Panel in September 2012 that this revolutionary product be made available to treat this patient population in the U.S.. We are thrilled to be able to offer the only FDA-approved long-term therapy for people suffering from advanced RP, said Robert Greenberg, MD, PhD, President and CEO of Second ...
Out of the five senses that you have, which is the one that you would deem to be most important? It would be an extremely difficult question for me to answer, as I treasure my sight, smell, touch, taste and hearing equally - and lacking in one is more than enough to make life difficult. Having said that, I salute the indomitable human spirit and those who have achieved so much more than normal able-bodied folks even when missing one (or more) of the five senses. Having said that, there is some hope for the blind thanks to the efforts of Second Sight who came up with the Argus II Retinal Prosthesis. This rather unique piece of technology will basically allow a blind user to see objects, as well as colors and movement within their environment. Just how is this achieved? Normally, it is done thanks to the assistance of a video-camera-equipped pair of glasses that is worn by the user. However, a recent experiment saw researchers do away with the camera, and they instead transmitted visual Braille ...
The attorney, Dean Lloyd, was one of six users of the Argus II retinal prosthesis who testified in front of a Food and Drug Administration (FDA) ophthalmic devices panel on September 28. They all urged its members to recommend marketing approval in the U.S. for the device.. I am happy to report that the panel did, in fact, vote to recommend marketing approval, and I think the heartfelt testimonies of those who used the Argus II in clinical trials helped move the panel toward that decision. The panels recommendation bodes well for final FDA approval, which will hopefully arrive in the not-too-distant future.. While Dean testified pragmatically - no surprise, he is a lawyer, after all - others who spoke about their experiences with the Argus II were quite emotional. For example, Cathy Blake, also blind from RP, became tearful as she explained how one of the most important benefits of using the Argus II is the ability to see movement.. What I really love most about the device is I can tell if ...

Purpose : To investigate the feasibility of implanting a newly developed wide-field dual-array suprachoroidal-transretinal stimulation (STS) prosthesis in healthy dogs and cats. Methods : Three healthy dogs and three healthy cats were used in this study. The STS dual array consisted of two arrays with 25 electrodes. The arrays were implanted into a scleral pocket of each of three healthy beagle dogs and three healthy cats under general anesthesia. Color fundus photography and Optical coherence tomography (OCT) were performed postoperatively. The animals were euthanatized after the experimental period and the retinas were evaluated histologically. Results : All the prostheses were successfully implanted without complications, and no serious complications occurred during the experimental period. The fixation of the implant was stable throughout the experimental period. Fundus photographs and OCT revealed no serious damage in the retina and choroid around the arrays ...

The research team have investigated the Argus II system both in terms of spatial resolution, using letter identification, and long-term stable function. In Test I on average, across all the subjects, letters could be clearly identified correctly between 51.7% (Group C) and 72.3% (Group A) of the time with the system on while performing at chance level with the device off. The median values for correct letters, system on, in figure 2 of 50% or greater for groups A, B and C indicate that at least half the group was functioning at this level (figure 2).. It is possible that a component of letter identification involves head scanning with light detection and inference of the letter. This may partially account for the greater number correct for Group A letters when the Test I letters were stratified into three groups of increasing typographic complexity. However, experimenters observed that many high-performing subjects did not scan across the letter but followed the form of the letter as if tracing ...

Based on the measured retinal locations, we calculated the angular distances between the centroid of the tested groups. The distance between the centroids of the groups in Figure 5 compared with the angular distance based on the physical separation between the electrodes are given in Table 2. The calculated angular distance assumed a linear model in which every 0.293 mm of arc length on the retina equates to 1° in the field of view.19 It can be seen that the subjects amplified the separation between the stimulation locations. This observation is in agreement with open-loop pointing with sighted subjects that shows that peripheral retinal displacement is exaggerated.20-22 Furthermore, we expect to see a deformation of the relative position and orientation between the electrodes because each electrode activates axon fiber tracts in addition to cell bodies. The activation of the fiber tracts might create an elongated percept along the axon.23 Thus, the percept can be moved along the direction of ...

PUNDI, BHARATRAM SATYANARAYANAN. Class-E Power Amplifier Design and Back-Telemetry Communication for Retinal Prosthesis. (Under the direction of Wentai Liu.) This thesis discusses the power link in the retinal prosthesis project that aims to provide vision to the profoundly blind. Clinical experiments have confirmed that electrical stimulation can be used to duplicate the action of photoreceptors in the retina to provide vision to blind patients suffering from RP/AMD. The retinal prosthesis system consists of an intraocular unit implanted inside the eye and a separate extraocular unit. The microstimulator involved in retinal prosthesis consists of multiple electrodes arranged in twodimensional array and is a part of the intraocular unit. The micro-stimulator needs data and power to be transferred wirelessly from the extraocular unit. The power link consists of a highly efficient Class-E driver that transfers power inductively to the intraocular unit. A Class-E power driver is developed to suit ...

Diseases like Retinitis Pigmentosa and Age-related Macular Degeneration result in a gradual and progressive loss of photoreceptors leading to blindness. A retinal prosthesis device imparts partial and artificial vision to patients in the central 15-20 degrees of the visual field by electrically activating the remaining healthy cells of the retina using electrical currents and an electrode array. Many visual aids available commercially aid blind patients with their day to day activities and navigation tasks. Most of these technologies have equipment or infrastructure overhead and are designed for indoor or outdoor use. The retinal prosthesis system design consists of an image processing module that can be utilized to process camera images in indoor and outdoor environments using algorithms to provide information about the surroundings and aid patients in their daily activities. This thesis presents work towards developing, validating and testing image processing algorithms for a retinal ...

The Intelligent Retinal Implant System (IRISTM) has been developed with the aim of providing modest visual perception to blind patients suffering from retinal degeneration e.g. retinitis pigmentosa. This epi-retinal prosthesis consists of an implantable part and two external parts. The implantable part is called the Retina Stimulator and is provided with energy wirelessly. The external components are the Visual Interface (VI) and the Pocket Processor (PP). The VI resembles a pair of sunglasses. A tiny camera is integrated within the Visual Interface to capture images from the patients surrounding and convert the image information into electronic signals. These signals are sent via a thin cable to the walkman sized Pocket Processor.. The PP processes the data and converts them into stimulation commands using very adaptable algorithms. The processed signals are then sent back via cable to the Visual Interface, where the signals are sent wirelessly to the implanted retina stimulator. The Retina ...

Retinal prosthesis devices have shown great value in restoring some sight for individuals with profoundly impaired vision, but the visual acuity and visual field provided by prostheses greatly limit recipients visual experience. In this paper, we employ computer vision approaches to seek to expand the perceptible visual field in patients implanted potentially with a high-density retinal prosthesis while maintaining visual acuity as much as possible. Approach. We propose an optimized content-aware image retargeting method, by introducing salient object detection based on color and intensity-difference contrast, aiming to remap important information of a scene into a small visual field and preserve their original scale as much as possible ...
Several studies have shown that rehabilitation can augment the brains inherent plasticity (Eickhoff et al., 2008; Kao et al., 2011; Martinez et al., 2009; Merabet & Pascual-Leone, 2010; Schlaug et al., 2009; Schneeberger et al., 2006, 2007). We are only beginning to understand how this finding applies to the use of AVDs in the field of artificial vision. New vision technology and efforts at ocular regeneration offer the eventual promise of meaningful improvement in the lives of people who are blind. However, this burgeoning field risks failure unless appropriate rehabilitative components are developed and multidisciplinary involvement occurs. Our results show that without instruction, the blind participants performed no better than chance when using the BrainPort vision device. However, after even a short amount of directed training in core skill acquisition, performance on the majority of outcomes significantly improved. Moreover, the scores for object and word recognition continued to improve ...

In the Soviet Occupied Zone that later became East Germany (see History of Germany since 1945), the development of law was not uniform. The Provincial High Court in Halle (Oberlandesgericht Halle, or OLG Halle) decided for Saxony-Anhalt in 1948 that Paragraphs 175 and 175a were to be seen as injustice perpetrated by the Nazis, because a progressive juridical development had been broken off and even been reversed. Homosexual acts were to be tried only according to the laws of the Weimar Republic.[27]. In 1950, one year after being reconstituted as the German Democratic Republic, the Berlin Appeal Court (Kammergericht Berlin) decided for all of East Germany to reinstate the validity of the old, pre-1935 form of Paragraph 175.[27] However, in contrast to the earlier action of the OLG Halle, the new Paragraph 175a remained unchanged, because it was said to protect society against socially harmful homosexual acts of qualified character.

With material in which several paragraphs are being quoted and omissions of full paragraphs occur, a period and ellipses at the end of the paragraph preceding the omitted material are sufficient to indicate this omission.Indeed, it is no more than the just desert of Dr Theodore Schott and his late brother to attribute to them the credit of having introduced and elaborated a method capable of restoring most cases of heart disease to a state of complete compensation, after the failure of other means, such as digitalis.… If the initial word(s) or the first sentence of the paragraph being quoted
The images are not merely identified, pointed out and listed.; there is active interpretation and analysis of what they actually mean. In other words the writer is actively engaging with Greenes story.. What of the second paragraph? Firstly one might ask why a second paragraph is needed, given that the theme is still that of religion. True, but the first paragraph is becoming quite long, it is reaching the natural length of a paragraph. There are no hard or fast rules and regulations here - no writing committee has decreed that a paragraph should contain an ideal number of words or sentences or run a certain length over a page. Extended writing practice will give you a feel and an instinct for realising that a paragraph is complete and it is time to start a new one. More importantly here there is a very strong sense that the first paragraph in the model is full. The writer has identified a link between the house and the ideological vacuum in which the gang exist and has tried to interpret ...
Objective measures that demonstrate activation of the retina, primary visual cortex, and possibly higher cortical association areas are necessary to illustrate the functionality of retinal prosthesis in sight-impaired subjects who have been implanted with such a device. Neural remodeling that occurs in outer retinal degenerative diseases can have an impact on the usefulness of retinal prostheses.; In this project we use quantitative positron emission tomography (PET) method coupled with metabolic radiotracer 18F-fluorodeoxyglucose (FDG) to evaluate brain activation under light stimulation and transcorneal electrical stimulation (TcES) conditions in normal sighted controls and subjects with retinal degeneration (RD). Both light stimulation and TcES resulted in activation of primary (BA 17) and secondary visual cortex (BA 18 and 19) in RD subjects. Transcorneal electrical stimulation using ERG-Jet corneal electrode resulted in similar subjective phosphene sensation in the right peripheral visual ...

Restoring vision to the blind is one of the epic promises of technology, sort of like flying cars, ray guns, and a lovable robot side kick. Yet artificial sight isnt a far off dream, its getting much closer to reality with the Argus project. Funded by the US Department of Energy and lead by Lawrence Livermore National Labs, Argus seeks to create an epiretinal prosthesis, a device that will take the image from a camera and send it to your brain via your optic nerve. The first two phases of Argus (which we call Argus I and Argus II) have had extraordinary success with implants in more than 30 patients. Now, LLNL is getting ready to launch Argus III - the third phase that will expand the number of patients, the quality of vision provided, and ease in which the device is implanted. The Argus project has already restored sight to a few blind people, but given enough time, it could change the lives of millions.. There are other epiretinal prosthesis in development. The one at MIT is particularly ...
In each of these questions you will be given a paragraph which contains all the information necessary to infer the correct answer. Use only the information provided in the paragraph. Do not speculate or make assumptions that go beyond this information. Also, assume that all information given in the paragraph is true, even if it conflicts with some fact known to you. Only one correct answer can be validly inferred from the information contained in the paragraph.. Pay special attention to quantifiers such as all, none, and some. Also, pay special attention to negative prefixes and negated verbs. For example, from a paragraph in which it is affirmed that it is not the case that all contracts are legal, one can validly infer that some contracts are not legal or that some contracts are illegal, or that some illegal things are contracts, but one cannot validly infer that no contracts are legal, or that some contracts are legal. Similarly, from a paragraph that states all contracts ...

After years of research, we are… able to offer a viable long-term solution for people suffering from advanced retinal degenerative diseases such as retinitis pigmentosa [RP], said Robert Greenberg, managing director, president and chief executive officer of Second Sight. The CE Mark approval… represents a huge step forward for the field and for these patients who have, until now, had no proven treatment alternatives.. Argus II is Second Sights second-generation implantable device intended to treat profoundly blind people suffering from degenerative diseases such as RP.. Second Sight said in a statement that the system converts video images captured from a camera - housed in the patients glasses - into a series of small electrical pulses that are transmitted wirelessly to an array of electrodes on the retina.. These pulses then stimulate the retinas remaining cells, resulting in the corresponding perception of patterns of light in the brain. Patients learn to interpret these visual ...
Second Sight Medical Products Inc. will conduct a clinical study in Germany to evaluate Argus II, its retinal prosthetic system, the company has announced.
A few years back, ophthalmologists diagnosed Niki Bayats father with glaucoma, a degenerative eye disease and leading cause of preventable blindness worldwide.. Bayat, a PhD student in chemical engineering at the USC Viterbi School of Engineering, watched helplessly as her father failed to take his drops three times daily as prescribed. Sometimes he forgot. Sometimes he had difficulty getting them into his eyes. Sometimes he only administered them once or twice a day because of the discomfort they caused.. Bayat, whose research includes developing biomaterials to treat eye trauma, thought there had to be another way. So she decided to develop one.. Bayat co-founded AesculaTech, a biomedical device company spun out of the research labs of Mark Thompson - her doctoral adviser, an expert in new materials for optoelectronics and co-inventer of the phosphorescent OLEDs now found in displays in mobile devices and televisions worldwide - and Mark Humayun - the developer of the Argus II, an artificial ...
SILVA, G. M. L. L. da et al. The use of an axisymmetric formulation of the Finite Volume Method for the thermal analysis of the retina and ocular tissues following implantation of retinal prosthesis. J. Braz. Soc. Mech. Sci. & Eng. [online]. 2012, vol.34, n.3, pp.308-313. ISSN 1678-5878. http://dx.doi.org/10.1590/S1678-58782012000300011.. This study analyzes the heat transfer in human eyes following implantation of retinal prostheses using an axisymmetric formulation of the Finite Volume Method. The model used consisted of a vertex centered unstructured grid finite volume method in an edge-based data structure and an explicit time integration. The results of the finite volume thermal analysis in ocular tissues were determined in the presence of two types of retinal implants: subretinal and epiretinal. For the subretinal device, the maximum temperature reached in the retina was 36.78°C (309.78 K) and the irreversible thermal damage occurred at 200 days. In the case of the epiretinal implant, the ...

Introduction. Heart of Darkness Commentary Mitchell Watson Period 23 November 15, 2012 Paragraph 28, Part Three of Heart of Darkness, written by Joseph Conrad, is part of the climax of the novella. The aforementioned section exists to show the reader that Marlow, the protagonist, is developing a relationship with the antagonist, Kurtz, in terms of intimacy and betrayal. Another function of this section is to show Marlow as both physically and metaphorically standing between Kurtz and a final plunge into madness and depravity. Conrad also utilizes Marlow and Kurtz as characters to set up a dichotomy of the primitive and civilized. Kurtz is described with a negative connotation in this section, as in ?-this wandering and tormented thing,? ?-utterly lost,? and ??unsteady, long, pale, indistinct like a vapour exhaled by the earth?? The simile ??indistinct like a vapour exhaled by the earth?? allows the reader to see Kurtz as only part of man. ...read more. Middle. The primitive and the civilized ...

paragraphs on conceptual photography. In conceptual photography the idea or concept is the most important aspect of the work. when a photographer uses a conceptual form of taking pictures, it means that all of the planning and decisions are made beforehand and the execution is a perfunctory affair. the idea becomes a machine that makes the picture. this kind of photography is not theoretical or illustrative of theories; it is intuitive, it is involved with all types of mental processes and it is purposeless. it is usually free from the dependence on the skill of the photographer as a craftsman. it is the objective of the photographer who is concerned with conceptual photography to make his work mentally interesting to the spectator, and therefore usually he would want it to become emotionally dry. there is no reason to suppose, however, that the conceptual photographer is out to bore the viewer. it is only the expectation of an emotional kick, to which one conditioned to abstract photography is ...

Indong Oh came to the United States from Corea in 1970 with his wife Kyungja. He completed his post-graduate surgical internship training at Harvard Medical School where he eventually became a professor in orthopedic surgery. He was also a resident at Massachusets General Hospital in Boston. Diligent and intensive practice with dogs during his residency led him to invent several major improvements in the existing art of joint-replacement devices. He has obtained 11 patents and designed 3 major total hip replacement prosthesis systems and attendant surgical instruments. The royalties from these devices assure him a seven-figure income even if he were to stop performing operations. But he has no interest in leading a life of leisure.. He keeps up a hectic private practice in which he specializes in hip and knee replacement surgery for patients suffering from disabling arthritis.

Losing focus within the passage. If you find yourself daydreaming or barely comprehending often, get in the habit of making the end of every paragraph a check point, where you pause to summarize the main idea of the paragraph you just read. Aside from forming a solid ongoing basis for your understanding of the passage, it also prevents you from continuing onward and compounding your lack of comprehension.. Passage is too boring. Note-taking is the most useful here; by forcing yourself to pay attention to something, your mind focuses more in general (this is also a fantastic technique for staying sharp in lectures and staff meetings, by the way!). You can also challenge yourself to take very concise, effective notes, which has the effect of forcing you to synthesize ideas and entire paragraphs into very small, meaningful phrases.. Passage is too interesting. This is a challenge, and is in some ways a little unfair: why should we have to stomp out a brief moment of fun in a four-hour stretch of ...

This is probably the fourth time I bring to your notice the following. Please, if you are not going to create original content for the articles you contribute to, try to improve the quality with which you add said information. The Afghanistan page is an example of that. The different paragraphs taken from different articles have no form of cohesive narrative or connectors. The focus of the article should be Afghanistan, not the people that visited or lived on it. There are even portions of this copy-pasted information that have nothing to do with Afghanistan, after mentioning that Dust was born in there, the information in the paragraph moves to India, and continues talking about Dusts life experiences even though they are completely irrelevant for the article. The paragraph about Wolverine tracking down Mystique mentions Afghanistan at the beginning. Then theres a mention of a flashback which takes place in Muir Island that has nothing to do with Afghanistan at all, and the action moves to ...
Your introduction is quite expansive and the first paragraph gives an excellent overview of what the somatosensory system actually is. At the end of the first paragraph you do refer to a picture; however, there is no picture. Please add this to show the somatosensory organisation within the body. In the second paragraph you mention some key timepoints related to the somatosensory development, which is good. After this (Development of the system entails…lemniscal system.) the text is probably too specific for the introduction. This can be used as an introduction for your development subheading. Please make sure that you edit the in-text references to proper references which we can access via your reference list. Also make sure you start adding terms to the glossary, eg. dorsal column-medial lemniscal system (I do not know what this means!) You have started on your history section, but it would be more interesting and easier to read if you put this in a table. For instance: date - description ...
