  1. logMAR VA, logarithm of the minimum angle of resolution visual acuity; macula (−), not involving macular region; macula (+), involving macular region.
  2. Ring 1, 2 and 3 comprised of 12 measure points at 5-, 3- and 1-degree radius circle centered at fovea, respectively. S4 is a measure point at fovea.
  3. Avg., average, RS, retinal sensitivity.
  4. P val: P value.
  5. *: P value < 0.05.
