Classification Maps: A New Mathematical Tool Supporting the Diagnosis of Age-Related Macular Degeneration

Objective: A new diagnostic graphical tool—classification maps—supporting the detection of Age-Related Macular Degeneration (AMD) has been constructed. Methods: The classification maps are constructed using ordinal regression model. In model, variable (the dependent variable) is degree advancement AMD. other variables, such as CRT (Central Retinal Thickness), GCC (Ganglion Cell Complex), MPOD (Macular Pigment Optical Density), ETDRS (Early Treatment Diabetic Retinopathy Study), Snellen and Age have also used in analysis represented on axes maps. Results: Here, 132 eyes were examined classified to AMD level according four-point Eye Disease Scale (AREDS): AREDS 1, 2, 3 4. These data for creation two-dimensional each four stages Conclusions: allow us perform patient’s particular pairs variables can be treated identifiers necessary
