tes a single dot of light at every stimulation point. As a result, multiple electrodes give visual patterns of single dots forming given images (Humayun et al., 2570).
             In the first test, the gentleman could tell the difference between a horizontal line and vertical line, which were both initiated for the patient to see. These given images were shown as lines and not dots, which is what they were in fact composed of. Secondly, a "U" shape was projected, but read as an "H" to the patient. Another patient was subjected to identifying a box of 3 x 3 of electrodes, but the patient had originally explained the image as bigger than given. She identified the box shape correctly. All in all, tests proved to be successful with minor complications (Humayun et al., 2572-73). This device conclusively forms partial visual images and patterns, but without the accessibility of being able to test the process in daily real life situations, than it is inconclusive whether or not one can function with this device beneficially everyday of their lives. But, the results that have been gathered are a positive outlook on the future developments and improvements of these types of devices (Humayun et al., 2575).
             Although using electrical devices was a good concept, using live animals intrigues scientists to be more useful using gene therapy. The first known experiment to find ways to restore vision using live animals and gene therapy would be mice. At this point it was apparent that intraocular injection reduced the loss of photoreceptors, it wasn't quite sure whether it would have long-term benefits. RP as mentioned before is a retinal disease that causes the extermination of photoreceptors, which cause people to become blind and have bad vision. The immense number of RP in people have led to the detection of RP causing genes in animal models. These animal models would in turn create the option of testing different theori...
