Purpose : To analyze the peripheral retinal vascular pattern in children who visited outpatient department with amblyopia using widefield fluorescein angiography.
Methods : We retrospectively reviewed the widefield fluorescein angiography images of children who visited clinic with amblyopia between January 2017 and December 2018. We analyzed the peripheral vascular patterns and divided them into two groups—loop pattern and branching pattern. We also investigated whether there is any difference in the peripheral retinal vascular patterns between normal adults and children.
Results : Thirty children were included. The mean age was 9.27±3.41 years old and there were 14 men (47.67%). Of these, fifteen children were in the loop pattern group and fifteen children were in the branching pattern group. The number of weeks at birth of the loop and the branching group was 32.92±5.62, 36.67±5.63 weeks, respectively(p=0.04). The birth weight of the loop and the branching group was 2.00±1.03 and 2.72±0.93 kg, respectively(p=0.03). Gender, age, delivery type, initial and final visual acuity were not different between the two groups. Retinal vascular leakage was more likely to be observed in the loop group than in the branching group (p=0.1). Of the 37 normal adults, 15 were in the loop group and 22 were in the branching group. The ratio of the two groups in adults did not differ from that of the two groups in children(p=0.47). The incidence of retinal microaneurysm and vascular leakage were lower in children than in adults (p=0.04, 0.001, respectively).
Conclusion : Lower birth weight and lower number of weeks at birth were observed when the peripheral retinal vascular morphologies of children were in loop patterns than in branching patterns. The difference in peripheral retinal vascular pattern according to birth weight and number of weeks at birth in children is thought to be due to the difference in the development of immature retinal vessels at birth.
