Abstract:
Objective To investigate the changes of the neurosensory retinal thickness in the macula in high myopia eyes by optical coherence tomography (OCT). Methods A total of 47 cases (47 eyes) of high myopia eyes and 42 cases (42 eyes) of normal eyes were divided into high myopia group and control group, respectively. The neurosensory retinal thickness in the center and at the edge of the fovea was measured by OCT. Meanwhile, the mean thickness of the neurosensory retina on OCT macular map was calculated automatically. The neurosensory retinal thickness in high myopia group was compared with that in the control group by t test. Results In high myopia group, the neurosensory retinal thickness in the center and at the edge of the fovea, parafovea, and perifovea was significantly thinner than that in the control group. However, no significant difference in the average thickness of neurosensory retina of the fovea was found between the two groups. Conclusion The thickness of the neurosensory retina in the macula in high myopia eyes is significantly thinner than that in normal eyes. When measurement of the neurosensory retinal thickness by OCT is performed, the thickness of a spot and the thickness of the area in which the spot is located should be considered.
