摘　　要：目的应用频域OCT(Hd-OCT)测量正常青少年黄斑部视网膜厚度范围。方法选择2018年1月~2019年1月我院眼科门诊查体的青少年345例(528眼),均行光学相干断层成像仪(Zeiss Hd-OCT)进行测量,比较不同性别和眼别黄斑区分区视网膜厚度(A1~A9)。结果Hd-OCT扫描检查的345例青少年黄斑区的OCT扫描形态呈两边高,中间低的特点。不同性别相同区域视网膜厚度比较,差异无统计学意义(P>0.05)。不同眼别相同区域视网膜厚度比较,差异无统计学差异(P>0.05)。黄斑中心区域内(直径1 mm)最薄,黄斑的内环区域(直径1~3 mm)最厚,外环区域(直径3~6 mm)较内环区域(直径1~3 mm)薄。在直径为1~3 mm的内环区,黄斑区视网膜厚度值依次为A5>A4>A2>A3。在直径为3~6 mm的外环区,黄斑区视网膜厚度值依次是A9>A6>A8>A7。结论Hd-OCT测量青少年黄斑区视网膜厚度有一定临床意义,可以建立青少年黄斑视网膜厚度的正常值数据库,为青少年黄斑发育的评估、黄斑疾病的定量检查、治疗后随访提供参考依据。Objective To measure the extent of macular retinal thickness in normal adolescents by frequency domain OCT(Hd-OCT).Methods From January 2018 to January 2019,345 adolescents(528 eyes)were enrolled in the ophthalmology clinic of our hospital.All of them were measured by optical coherence tomography(Zeiss Hd-OCT)to compare the sexes and eye spots.Area partition retinal thickness(A1~A9).Results The OCT scan pattern of 345 adolescent macular areas examined by Hd-OCT scan was high in both sides and low in the middle.There was no significant difference in retinal thickness between the same sex regions(P>0.05).There was no significant difference in retinal thickness between the same eyes in different eyes(P>0.05).The innermost area of the macula(diameter 1 mm)is the thinnest,the inner ring area of the macula(diameter 1~3 mm)is the thickest,and the outer ring area(diameter 3~6 mm)is thinner than the inner ring area(diameter 1~3 mm).In the inner ring region with a diameter of 1~3 mm,the retinal thickness values in the macular area are A5>A4>A2>A3.In the outer ring area with a diameter of 3~6 mm,the retinal thickness values in the macular area are A9>A6>A8>A7.Conclusion Hd-OCT has a certain clinical significance in measuring the retinal thickness of adolescent macular area.It can establish a normal value database of adolescent macular retinal thickness,and provide reference for the evaluation of adolescent macular development,quantitative examination of macular disease and follow-up after treatment.
