Multicenter normative data for mesopic microperimetry

This record contains the analysis and underyling data presented in the manuscript Pfau et al. 'Multicenter normative data for mesopic microperimetry'. 

Contents:

• 2024-08-30_Multicenter-Normal-Data.csv: Newly published normal data for mesopic microperimetry
• 2024-08-30_Analysis.R: Analysis script
• 2024-08-30_Vignette-to-create-normal-data.R: Software example to create normative maps

The subfolders Figures and Tables show the analysis results.

The folder Intermediary_Results contains the results of the cross-validation folds to assess model perfromance.

To run the analysis code in 2024-08-30_Analysis.R, the following data is needed in addition:

The 2024-08-30_Multicenter-Normal-Data.csv file with the data contains the following columns:

• source: Describes the clinical site
• MachineID: ID of the MAIA device used for data collection
• ParticipantID: ID of the participant
• EID: ID of the eye
• eye: Laterality (either Right or Left)
• sex: Sex (f for female, m for male)
• age: Age in years
• ExamID: ID of the exam
• ExamBaselineID: ID of the corresponding baseline exam (-1 indicates that the exam itself is the baseline exam)
• GridUsed: Name of the grid
• falsepos: Rate of false positive responses to Heijl-Krakau stimulus presentations to the optic nerve head (blind spot)
• bcea63_area_deg2: Fixation stability in terms of the bivariate contour ellipse area covering 63% of the fixation points (in square degree)
• bcea95_area_deg2: Fixation stability in terms of the bivariate contour ellipse area covering 95% of the fixation points (in square degree)
• pointID: ID of the test point
• eccentricity: Eccentricity of the test point (in degree)
