Fundus photographs showing veins are convoluted and slightly dilated, but arteries have straight courses.

However, the course and shape of the veins were normally straight in the peripheral retina (Figure 1).
The cilioretinal artery course inferotemporally from behind the disc margin (arrow).

Additionally, funduscopy showed vessels that appeared from behind the disc margin and coursed inferotemporally toward the fovea in the posterior retina, which were considered to be cilioretinal arteries (Figure 2).
The cilioretinal artery begins to fluoresce at early phase angiogram (13.7 seconds).

Fluorescein angiography of the right eye demonstrated that the arteries begin to fluoresce at 13.7 seconds as the choroid fluoresces (Figure 3), rather than as the retina fluoresces.

Furthermore, the fluorescein angiogram of the arteriovenous phase showed obviously tortuous and dilated retinal veins without any leakage or dye (Figure 4).
