Sung MS, et al. - Authors assessed the clinical characteristics of β-PPA in myopic eyes and ascertained whether or not the microstructure of β-PPA was related to parapapillary microvasculature by using optical coherence tomography (OCT) angiography. In the microvasculature, they observed significant differences according to the microstructure of β-PPA. A close correlation of PPA_+BM (Bruch’s membrane) width with superficial and deep parapapillary vessel density was noted. More inferiorly rotated optic disc, larger β-PPA, and lower superficial and deep parapapillary vessel density was seen in the PPA_+BM only group compared with those of the PPA-BM only group.
