Cross-classification of study eyes according to spatial distribution patterns of MPOD: comparison of baseline and follow-up examinations. Ring_BL = ring-like MPOD distribution at baseline. Intermediate_BL = intermediate MPOD distribution pattern at baseline. No Ring_BL = monotonously decreasing MPOD distribution at baseline. Ring_FU = ring-like MPOD distribution at 3.96 years follow-up. Intermediate_FU = intermediate MPOD distribution pattern at 3.96 years follow-up. No Ring_FU = monotonously decreasing MPOD distribution at 3.96 years follow-up
