Abstract

Purpose : To characterize the appearance of peripheral fundus of normal eyes via ultra-widefield fluorescein angiography (UWFA).

Methods : A total of 123 eyes of 78 subjects with best corrected visual acuity > 1.0, without any visible pathologic changes in the retina underwent Heidelberg UWFA and Heidelberg 55-degree FA. According to peripheral angiographic findings, eyes were allocated into three groups: group 1 without mottled fluorescent band and retinal vascular leakage; group 2 with mottled fluorescent band and without retinal vascular leakage; group 3 with vascular leakage, regardless of the existence of mottled fluorescent band. Ciliary body thickness (CBT) was measured by ultrasound biomicroscopy and compared in three groups.

Results : In the ora serrata region, a mottled fluorescent band was detected in 54 eyes (43.9%). In retinal periphery just posterior to the ora serrata, a granular band of background fluorescence appeared in all eyes (100%) and vascular leakage was observed in 40 eyes (32.5%). No sex and age differences existed between three groups. CBT values of group 1 (CBT1: 0.240+0.019mm, CBT2: 0.375+0.051mm) and group 2 (CBT1: 0.251+0.030mm, CBT2: 0.410+0.050mm) showed no statistical difference (p = 0.531 for CBT1, p = 0.150 for CBT2); while CBT values of group 3 (CBT1: 0.337+0.046mm, CBT2: 0.623+0.107mm) were significantly different from those of the other two groups (p = 0.000 for both CBT1 and CBT2), indicating potential inflammation in eyes of vascular leakage.

Conclusions : Standard peripheral fundus has a granular band of background fluorescence, without any mottled fluorescent band or vascular leakage. The mottled fluorescent band may be a kind of developmental variation, while the vascular leakage may be an early sign of uveitis.
