Means and SDs with CIs (95%) were calculated for binocular UDVA, UIVA, and UNVA for each group. Likewise, percentages corresponding to each answer of questions about patient satisfaction, spectacle independence, and photic phenomena were determined for each group. SPSS statistics software package version 15.0 for Windows (SPSS Inc., Chicago, IL, USA) was used for these analyses.

Data was calculated as mean ± SD (range). One eye from each subject was randomly selected for the analyses. The SPSS statistics software package version 15.0 for Windows (SPSS, Chicago, IL) was used for statistical analysis. Normality of all data samples was checked by means of the Kolmogorov-Smirnov test. When parametric analysis was possible, the Student t test for paired data was performed in all parameter comparisons between patients with PD and age-matched healthy controls. When parametric analysis was not possible, the Wilcoxon rank-sum test was used. In addition, correlation coefficients (Pearson or Spearman depending on whether normality condition could be assumed) were calculated to assess the correlation between SD-OCT measurements and PD severity and duration. Intraclass correlation coefficient (ICC) also was performed for interobserver and intraobserver reliabilities. A P value less than 0.05 was considered statistically significant.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
