摘要:

目的 探讨黄斑区视网膜神经节细胞复合体(GCC)厚度检测对于诊断视野前青光眼(PPG)患者的意义。设计 自身对照研究和病例对照研究。研究对象 POAG患者20例40眼(无视野缺损眼为PPG组20眼,视野缺损眼为POAG组20眼)和正常对照者30例30眼。方法 采用RTvue SD-OCT进行黄斑区GCC厚度和视盘周围视网膜神经纤维层(RNFL)厚度检测,应用受试者工作特征曲线下面积(AUC)评价各参数区分PPG与正常眼的能力。主要指标 GCC与RNFL的厚度以及二者AUC值。 结果 PPG组平均GCC厚度(Avg GCC)、上方GCC厚度(Sup GCC)、下方GCC厚度(Inf GCC)、平均RNFL厚度(Avg RNFL)、上方RNFL厚度(SupRNFL)、下方RNFL厚度(Inf RNFL)与正常对照组相比均变薄,差异有统计学意义(t=5.508,5.402,5.576,6.517,5.849,5.392,P均<0.001),但均厚于POAG组,差异有统计学意义(t=4.778,3.698,4.593,5.209,3.757,5.450,P均 ≤0.002)。PPG组GCC整体丢失体积(GCC-GLV)和局部丢失体积(GCC-FLV)均较正常对照组增大,差异有统计学意义(t=6.539,2.515,P<0.001,P=0.021),但较POAG组小,差异有统计学意义(t=6.013,7.669,P均<0.001)。Avg GCC、Sup GCC、Inf GCC、GCC-GLV、GCC-FLV、Avg RNFL、SupRNFL和Inf RNFL厚度诊断PPG的AUC值分别为0.910、0.898、0.908、0.983、0.724、0.930、0.918、0.863,其中GCC参数中诊断效能最高的GCC-GLV与RNFL参数中的Avg RNFL的AUC值采用z检验无统计学差异(P>0.05)。结论 GCC厚度可作为筛选PPG的有效指标。(眼科, 2017, 26: 10-14)

Abstract:

Objective To evaluate the diagnostic capabilities of ganglion cell complex (GCC) thickness in preperimetric glaucoma (PPG) with spectral domain optical coherence tomography (SD-OCT). Design Self control study and case control study. Participants Primary open-angle glaucoma (POAG) patients were 20 cases(40 eyes), of which 20 eyes without visual field defects as PPG, and healthy controls were 30 cases(30 eyes). Methods All subjects were underwent macular scanning and peripapillary retinal nerve fiber layer (RNFL) scanning using the RTvue SD-OCT. The area under the receiver operating characteristic curve (AUC) was used to assess the ability to discriminate PPG from normal control. Main Outcome Measures The thickness of GCC and RNFL, and their AUCs. Results Compared with normal eyes, the thickness of average GCC, superior GCC, inferior GCC, average RNFL, superior RNFL, and inferior RNFL in PPG eyes decreased (P<0.001). However, these parameters were thicker than POAG eyes (P≤0.002). The values of GCC-GLV and GCC-FLV increased compared with normal eyes (P<0.001, P=0.021), but decreased compared with POAG eyes (P<0.001). GCC-GLV had highest AUC for detecting PPG (0.983) from normal eyes, followed by average RNFL (0.930). However, the difference between the two parameters was not statistically significant (P>0.05). Conclusions In addition to RNFL, the GCC could be a structural parameter for detecting PPG. (Ophthalmol CHN, 2017, 26: 10-14)
