The correlation of atrophy, traction and neovascularization in myopic choroidal neovascularization according to a novel myopic maculopathy classification system (atrophy (A), traction (T), neovascularization (N): ATN).

ATN classification is a practical and comprehensive system to grade myopic CNV. Atrophy is an independent predictor for myopic CNV scar and patchy chorioretinal atrophy requires a more careful examination and close follow-up for the risk of CNV development.
