Registered average of confocal retinal vessel images of (a) N1 at ${6.6}^{\circ }$ T $2^{\circ }$ SR, (b) N2 at ${4.25}^{\circ }$ T ${1.7}^{\circ }$ IR, (c) N3 at $5^{\circ }$ T ${0.15}^{\circ }$ SR obtained with vertical line illumination. (d)-(f) The corresponding phase contrast images acquired simultaneously. The orange lines indicate the orientation of the line illumination. The scale bar is 20 $\mu$ m.
