Anraku Ayako, Enomoto Nobuko, Tomita Goji, Iwase Aiko, Sato Takashi, Shoji Nobuyuki et al.
This study found that optic nerve head blood flow measurements by LSFG are significantly influenced by systemic factors (blood pressure, age) and ocular factors (axial length, disc/cup/ฮฒ-PPA area), requiring adjustment for accurate interindividual comparisons.
