近视眼黄斑区视网膜厚度与眼轴的相关性研究

目的 探讨近视眼黄斑区视网膜厚度(R T)与眼轴长度的相关性。 方法 应用Zeiss Humphrey光相干断层成像仪( OCT) 测量近视眼67例(106只眼)的黄斑中心凹中心，中心凹和旁中心凹上方、下方、鼻侧、 颞侧RT。应用IOL Master测量仪测量被检眼的眼轴长度，并对眼轴长度与近视眼视网膜的厚度进行相关分析。 结果 近视眼中心凹最小RT(150.90 ±22.10) μm。颞侧旁中心凹区视网膜最薄。近视眼黄斑旁中心凹各区域平均厚度与眼轴长度呈负相关，中心凹最小RT、中心凹平均RT与眼轴长度无相关。 结论 随着眼轴长度的增加,旁中心凹视网膜变薄,中心凹的最小RT及中心凹区的平均RT没有变化。 (中华眼底病杂志, 2006, 22: 397-399)

Relationship between retinal thickness at the macular area and axial length in myopia

Objective To evaluate the correlation between retinal thickness (RT) at the macular area and the axial length (AL) in myopia. Mehtods Optical coherence tomography (OCT) was used to detect the RT at the macular fovea, and at the superior, nasal, inferior, and temporal side of the fovea and parafovea area. The AL of the examined eye was measured by IOL master measuring machine, and the correlation between RT at the macular area and the Al was evaluated. Results The minimum RT in the macular area in the eyes with myopia was (150.90±22.10)μm.The retina at the temporal side of parafovea was the thinnest. The average RT in the areas around the fovea was negatively correlated with the AL, and there was no correlation among the minimum RT, the mean RT at the fovea, and the AL of eye. Conclusions As the AL of eye increases, the RT at the parafovea decreases, while the minimum and the average RT at the fovea remain unchanged.  (Chin J Ocul Fundus Dis, 2006, 22: 397-399)
