摘  要:目的观察水通道蛋白-4抗体阳性视神经炎[AQP4-Ab(+)ON]患者盘周视网膜神经纤维层(pRNFL)厚度及黄斑区内层视网膜结构改变特点。方法临床检查确诊的视神经炎(ON)患者60例84只眼(0N组)以及与患者无血缘关系的同期正常对照者40名80只眼(HC组)纳入研究。其中,ON组患者根据血清AOP4-Ab检查结果,分为AQP4-Ab(+)ON组、AQP4-Ab阴性ON组[AQP4Ab(-)ON组]。两组患者各30例42只眼。均行最佳矫正视力(BCVA)、眼前节、眼底及光相干断层扫描(OCT)检查。BCVA记录时换算为最小分辨角对数(10gMAR)视力。3组受检者间性别(x^2=0.568)、年龄(x^2=1.472)比较,差异无统计学意义(P=0.753、0.497)。AQP4-Ab(-)ON组、AQP4-Ab(+)ON组间不同病程眼数(x^2=0.000)、平均logMARBCVA(Z=-1.492)比较,差异无统计学意义(P=1.000、0.136)。采用Spectralis—OCT仪行视盘及黄斑区扫描。应用标准视神经扫描模式的pRNFL程序,对盘周及其鼻侧、鼻下、颞下、颞侧、颞上、鼻上象限和盘斑束(PMB)厚度及鼻侧、颞侧pRNFL平均厚度比(N/T))进行分析。将黄斑部划分为以黄斑中心凹为中心,分别为直径1mm的中心区,1mm〈直径≤3mm的内环区,3mm〈直径≤6mm的外环区等3个同心圆区域。应用黄斑程序对中心区外的内外环其他8个分区的黄斑容积及黄斑部RNFL(mRNFL)、神经节细胞层(mRGCL)、内丛状层(mIPL)、内核层(mlNL)容积进行分析。结果与HC组比较,ON组患眼pRNFL平均厚度及视盘各象限、PMB平均RNFL厚度均明显降低,差异有统计学意义(P=0.000);黄斑容积及mRNFL、mRGCL、mIPI,容积明显减小,差异有统计学意义(P=0.000);mINL容积无明显变化,差异无统计学意义(P=0.700)。AQP4-Ab(+)ON组pRNFL平均厚度,视盘各象限、PMB平均RNFL厚度均较AQP4-Ab(-)ON组降低,其中Objective To observe the thickness of per-papillary retinal fiber layer (pRNFL) and structural changes of inner macular segmented layers in optic neuritis (ON) patients with positive aquaporin- 4 antibody rAQP4-Ab(+)].. Methods 60 ON patients (84 eyes) including 30 of AQP4-Ab(+) ON patients (42 eyes) and AQP4-Ah(- ) ON patients (42 eyes), and 40 age-gender matched health controls(80 eyes) were recruited in present study. There was no statistical significance in gender (x^2 =0. 568) and age (x^2 = 1. 472) between the three groups (P)0.05). There was no statistical significance in the percentage of different course (x^2 =0. 000) and logMAR best corrected visual acuity (Z= - 1. 492) between AQP4-Ab (+)ON and AQP4-Ab( - )ON group (P=1. 000, 0. 136). All subjects were examined by Spectralis-OCT. The thickness of per-papillary, nasal, nasal lower, temporal lower, temporal, temporal upper, nasal upper and papillomacular bundle (PMB) were analyzed as well as nasal pRNFL/temporal pRNFL (N/T). The macular area was divided into three concentric circles which including central region with 1 mm diameter, inner area with 〉1 mm but ≤3 mm diameter, and outer ring area with 〉3 mm but ≤6 mm diameter. The macular volume in each partition and volume in macular RNFL (mRNFL), macular ganglion cell layer (gnRGCL), macular inner plexiform layer (mlPL) and macular inner nuclear layer (mINL) were analyzed. Results Compared to HC group, the thickness of pRNFL, every quadrants and PMB were decreased significantly in ON group (P= 0. 000) ; the macular volume and the volume of mRNFL, mRGCL, mIPL were also decreased significantly in ON group (P=0. 000); but there was no statistical difference in mINL volume between two groups (P = 0. 700). Compared to AQP4-Ab(-) ON group, the thickness of nasal and nasal lower were decreased significantly in AQP4-Ab( +)ON group (P=0. 010, 0. 000); the macular and mIPL volume w
