Summary

AIM: To study the relationship between optical coherence tomography angiography(OCTA)and eye axis in adolescents. 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.
