目的：研究光学相干断层扫描血管成像(OCTA)检查在青少年受检者中的检查情况及其与眼轴之间的关系。

方法：前瞻性非随机临床研究。收集青少年受检者33例66眼的临床资料进行分析。所有受检者行裸眼视力、屈光度、矫正视力检查后，行眼轴测量及OCTA检查。采用SPSS19.0软件分析OCTA各检测结果及其与眼轴之间的关系。

结果：受检者眼轴长度平均为24.46±1.50mm，黄斑区平均血管密度为(47.88±2.56)%，黄斑区平均神经纤维层厚度为278.61±15.08μm，视盘周围平均血管密度为(57.79±2.99)%； 视盘周围平均毛细血管密度为(53.08±3.49)%； 其中眼轴长度与黄斑区神经纤维层厚度呈负相关(P=0.006)，眼轴与其他检测结果均不相关。

结论：青少年眼底OCTA的检测指标中，黄斑区神经纤维层厚度与眼轴之间呈负相关，血管密度方面的检测指标与眼轴均无相关性。

METHODS: Prospective non-randomized clinical study. The clinical data of 33 cases(66 eyes)were collected and analyzed. All the subjects underwent naked vision, diopter, corrected visual acuity, axial measurement and OCT examination. SPSS 19.0 software was used to analyze the relationship between the results of OCTA and the eye axis.

RESULTS: The mean axial length was(24.46±1.50)mm, the mean vascular density in macular area was(47.88±2.56)%, and the mean thickness of nerve fiber layer in macular area was(278.61±15.08)μm. The mean perioptic vessel density was(57.79±2.99)%, and the mean capillary density was(53.08±3.49)%. There was a negative correlation between the length of the eye axis and the thickness of the nerve fiber layer in the macular area(P=0.006), but there was no correlation between the axial length and the other results.

CONCLUSION: There was a negative correlation between the thickness of nerve fiber layer in macular area and the eye axis, but there was no correlation between the blood vessel density and the eye axis in the detection of fundus OCTA in adolescents.
