Researchers from Moorfields Eye Hospital Detail New Studies and Findings in the Area of Ophthalmology (The Argus II prosthesis facilitates reaching and grasping tasks: a case series)

By a News Reporter-Staff News Editor at Health & Medicine Week -- Fresh data on Health and Medicine are presented in a new report. According to news originating from London, United Kingdom, by NewsRx correspondents, research stated, "To evaluate the reach-to-grasp performance of patients fitted with an epiretinal artifical retina device. This was a hospital-based case series consisting of six patients fitted with the Argus II (Second Sight Medical Products Inc, California, USA) retinal prosthesis."

Our news journalists obtained a quote from the research from Moorfields Eye Hospital, "Participants were asked to reach out and pick up a high-contrast cuboid object with the prosthesis in the 'On', 'Off' or 'Scrambled' setting presented in a randomised order. The 'Scrambled' setting consisted of a random, scattered signal presented to the prosthesis. The session was repeated after a 4-6 week period. Hand movements were measured using motion detection cameras. The number of successful object grasps was calculated. The number of successful grasps was greater with the prosthesis in the 'On' setting (visit 1: median [interquartile range] percentage success: 'Off' = 0 [0 to 50]%, 'On' = 69 [67 to 95]%, 'Scrambled' = 59 [42 to 95]%; Friedman Chi-squared test statistic 6.5, p = 0.04; visit 2 median [IQR] percentage success: 'Off' = 0 [0 to 25]%, 'On' = 69 [53 to 100]%, 'Scrambled' = 28 [13 to 63]%; Friedman Chi-squared test statistic 8.4, p = 0.02). The use of an electronic retinal prosthesis facilitates reach-and-grasp performance."

According to the news editors, the research concluded: "Further work should explore how performance can be improved with targeted rehabilitation."
