Choroidal arterial watershed zone topography and its relationship with maculopathy in highly myopic eyes.

Variations in CWZ topography are associated with myopic maculopathy, particularly in eyes with myopic choroidal neovascularization (mCNV) and macular atrophy, and CWZ is a risk factor for mCNV. This suggests that eyes with macular CWZs are vulnerable to developing myopic maculopathy and are predisposed to mCNV because of ischaemic hypoxia.
