Figure 1. The fundus photography of each category of META-PM classification. (A) Category 0: no myopic retinal degenerative lesion. (B) Category 1: tessellated fundus. Thinning of the retina results in increasing visibility of the deep choroidal vessels. (C) Category 2: diffuse chorioretinal atrophy. An ill-defined yellowish-white lesion can be seen in the posterior pole. (D) Category 3: patchy chorioretinal atrophy. Multiple grayish-white, well-defined atrophy can be seen. The fovea is spared. (E) Category 4: macular atrophy. Atrophy involves the fovea. (F) Lacquer cracks (indicated by white arrow) in the background of patchy chorioretinal atrophy. (G) Active myopic CNV with bleeding (indicated by white arrow) in the background of patchy chorioretinal atrophy. (H) Fuchs’ spot (indicated by white arrow) in the background of macular chorioretinal atrophy. META-PM: meta-analysis for pathologic myopia; CNV: choroidal neovascularization.
