From: Peripapillary vessel density correlates with visual field mean sensitivity in highly myopic eyes
The average level of pRNFL, pVD and VFMS in four groups and the comparisons between groups. The average level of the peripapillary retinal nerve fibre layer (pRNFL) thickness assessed by optical coherence tomography (OCT) showed no statistically difference between four groups (the left part of (A). The average level of visual filed mean sensitivity (VFMS) was significantly lower in group 4 than in group 1,2 and 3(the right part of A). Peripapillary vessel density (pVD) assessed by optical coherence tomography angiography (OCT-A) showed a deceasing trend from group 1 to 4(the left part of B). a, b, c: statistical differences between groups were marked by letters, with groups sharing at least one similar letter presenting no statistically significant difference (p ≥ 0.05) and groups with all different letters presenting a significant difference (p < 0.05)
