摘　　要：目的应用频域OCT(光学相干断层扫描成像,Optical coherence tomography)技术分析研究病理性近视眼黄斑区视网膜神经上皮层厚度的变化特点。方法选取2012年2—12月在该院眼科行黄斑区频域OCT检查的病理性近视眼患者63例(63眼)作为观察组和正常眼患者54例(54眼)作为对照组,对其黄斑区视网膜进行测量,记录黄斑区9个分区的视网膜神经上皮层的平均厚度。结果 A1、A5区察组(病理性近视眼组)和对照组(正常眼组)之间的差异均无统计学意义(均为P>0.05);A2、A3区观察组(病理性近视眼组)均低于对照组(正常眼组),P<0.05,两组间的差异均有统计学意义;A4、A6、A7、A8、A9区,观察组(病理性近视眼组)均低于对照组(正常眼组),P<0.01,两组间的差异均有显著的统计学意义。结论病理性近视对视网膜特别是黄斑部的影响是确实存在的,频域OCT能够精确量化该厚度的变化。Objective Application of frequency domain OCT （Optical coherence tomography） technology analysis of pathologic myopia macular neurosensory retinal thickness changes. Methods Collected 63 subjects （63 eyes） of pathologic myopia eyes and 54 subjects （48 eyes）of normal eyes from February 2012 to December 2012, divided them into pathologic myopia group and normal eye group.We measured the thickness of neurosensory retina of macular. Results A1, A5 between the observation group （pathologic myopia group）and control group （normal group）were no statistically significant differences （P 〉 0.05） ; A2, A3 in the observation group （pathologic myopia group） were lower than the control group （normal group）, P 〈 0.05, the difference between the groups had statistical significance; A4, A6, A7, A8, A9, the observation group （pathologic myopia group） were lower than the control group （normal group）, P 〈 0.01, statistically significant differences between the two groups. Conclusion The influence about pathologic myopia on retinal especially macular really exists, OCT can exactly measure these changes of the thickness.
