Effect of the electrode array-retina gap distance on visual function in patients with the Argus II retinal prosthesis

Table 3 Results of Square Localization (SL) and Direction of Motion (DOM) Testing at month 3 (M3), month 6 (M6), and year 1 (Y1) measured as a change in pixels (SL) or degrees (DOM) between testing with the device OFF and ON (Δ^OFF-ON). A positive number indicates an improvement with the device ON
