BRVO: branch retinal vein occlusion; S-Hemi: superior hemifield; I-Hemi: inferior hemifield; S: superior quadrant; T: temporal quadrant; I: inferior quadrant; N: nasal quadrant; NS: nasal superior sector; NI: nasal inferior sector; IN: inferior nasal sector; IT: inferior temporal sector; TI: temporal inferior sector; TS: temporal superior sector; ST: superior temporal sector; SN: superior nasal sector. G11-G33: the  mm area was divided into 9 equal parts, the three cells in the first row are named G11, G12, and G13; the three cells in the second row are named G21, G22, and G23; the three cells in the third row are named G31, G32, and G33. All data are presented as , was considered statistically significant.
