(A) CS function values for study eyes (ie, eyes with macula-off rhegmatogenous retinal detachment ) with best-corrected visual acuity (BCVA) of 20/50 or better and the corresponding fellow eyes for specific spatial frequency values. (B) Difference function between retinal detachment eyes and fellow eyes. Error bars indicate SE. Specific values are also provided in Table 4. (B) Difference between CS values in study eyes with BCVA of 20/50 or better and corresponding fellow eyes. Difference in values at 1.5, 3, 6, 12, and 18 cycles per degree were 0.11, 0.11, 0.19, 0.26, 0.19, respectively.
