Editor, T he spectrum of myopia can be divided into moderate myopia and high myopia. The clinical importance of the differentiation between both types of myopia is based on findings that high myopia in contrast to moderate myopia is associated with a higher glaucoma susceptibility, a lower number, smaller size and less advanced type of macular drusen corresponding with a lower risk of early and late age-related macular degeneration, a higher risk for exudative myopic maculopathy, a larger optic nerve head, a decreased best corrected visual acuity and a higher frequency of visual field defects (Xu et al. 2007a).
