摘要：This preliminary study analyzed the peripheral retinal vascular pattern in children, using ultra-widefield fluorescein angiography, and its association with perinatal conditions. Retrospective review was conducted examining the fluorescein angiographic findings of children with amblyopia (January 2017 to December 2018). We categorized the peripheral vascular patterns into two groups: loop and branching patterns. We investigated differences in these patterns, according to the perinatal condition. Thirty children (9.27 ± 3.41 years old; 47.67% male) were included. An equal number of children had the loop or branching pattern (15:15). The gestational age (GA) in the loop group was significantly shorter than the branching group (32.92 ± 5.62 vs. 36.67 ± 5.63 weeks, p = 0.04). The birth weight of the loop group was significantly lower than the branching group (2.00 ± 1.03 vs. 2.72 ± 0.93 kg, p = 0.03). Gender, age, delivery-type, and visual acuity, were not different between the groups. Lower birth weight and shorter GA were observed in children with the loop pattern. The difference in peripheral retinal vascular patterns, according to birth weight and GA, might be due to the development of immature retinal vessels at birth.
