Structural Characteristics of Parapapillary Choroidal Microvasculature Dropout in Primary Open-Angle Glaucoma: Comparison Between Width and Area.

In the multivariable model, an increased circumferential width of the CMvD was significantly associated with a worse VF mean deviation ( P =0.046), thinner global RNFL thickness ( P =0.049), and larger β-PPA area ( P =0.013, Figure 3a–c ). In contrast, a larger CMvD area was significantly associated only with a larger area of β-PPA and γ-PPA ( P =0.001 and P <0.001, respectively), whereas other functional and structural glaucomatous parameters did not reach statistical significance.
