摘  要:目的研究多发性硬化(Ms)患者视网膜神经纤维层(RNFL)厚度与视功能、疾病病程及系统功能障碍之间的联系,评估RNFL厚度作为衡量MS病程中轴突缺失的生物学指标的意义。方法横断面研究。MS患者17例(32眼),平均年龄(45.0±15.9)岁,及年龄、性别相匹配的健康对照者17例(17眼).平均年龄(43.3±14.9)岁。对所有患者和对照者均行全面的眼科检查,包括最佳矫正视力、光学相干断层扫描(OCT)测量RNFL厚度、图形视觉诱发电位(PVEP)及视网膜电图(ERG)检查。患者还进行了神经系统评估(以EDSS评分表示)。根据有无视神经炎(ON)发作史将MS患者分为MS-ON组(16眼)和MS-NON组(16眼)。采用单因素方差分析对MS-ON组、MS-NON组和对照组的RNFL厚度、PVEP及ERG结果的差异进行分析.采用Spearman相关分析RNFL厚度与EDSS评分、病程及电生理结果之间的相关性。结果MS-ON组的平均、上方、下方、颞侧、鼻侧RNFL厚度分别为(72.4±16.6)、(80.5±26.3)、(84.2±29.5)、(65.8±14.0)、(54.2±16.4)μm,与对照组[(105.6±10.8)、(119.7±18.2)、(123.5±17.9)、(91.1±21.2)、(88.2±13.0)wm]相比均较薄(P均=0.000)。MS-ON组与MS-NON组[(98-3±12.0)、(115.5±18.2)、(117.7±21.5)、(72.0±15.0)、(68.1±16.1)μm1相比,平均、上方、下方及颞侧的RNFL厚度差异有统计学意义俨均〈0.05),而鼻侧的RNFL厚度差异则无统计学意义。MS-NON组与对照组相比,颞侧和鼻侧的RNFL厚度较薄(P均〈0.05),而平均、上方、下方的厚度相比差异均无统计学意义。MS-ON组患者的平均RNFL厚度与MS病程[(8.8±9.8)年]、EDSS评分(2.9±2.2)均呈负相关(r=-0.659、-0.741,P均〈0.05)。而MS.NON患者的平均RNFL厚度与MS病程、EDSS评分的相关性Objective To study the relationship between retinal nerve fiber layer (RNFL) thickness measured by optical coherence tomography (OCT) and visual function, disease course and system dysfunction in patients with multiple sclerosis (MS); to evaluate the significance of RNFL thickness as a biological marker for axonal loss in the course of MS disease. Methods This was a cross-sectional study. Seventeen MS patients (32 eyes) and 17 healthy people (17 eyes) were matched by age and sex. All participants received a neurological evaluation and a complete ophthalmological examination, including visual acuity, OCT measurement of RNFL thickness, pattern visual evoked potentials (PVEP) and electroretinography (ERG) examinations. Patients were divided into three groups: MS patients with a history of optic neuritis (MS-ON group), MS patients without a history of optic neuritis (MS-NON group) and the control group. The results of OCT measurement of RNFL thickness, and PVEP and ERG examinations of the three groups were compared by ANOVA. The relationshipbetween RNFL thickness and the score on the expanded disability status scale (EDSS), and disease course, and electrophysiology results were analyzed by Spearman correlation analysis. Results The MS-ON eyes showed RNFL thinning in the average, superior, inferior, nasal, and temporal quadrants [(72.4±16.6), (80.5±26.3), (84.2±29.5), (65.8±14.0), (54.2±16.4)μm] compared to the control eyes [(105.6±10.8), (119.7±18.2), (123.5±17.9), (91.1±21.2), (88.2±13.0)μm] (P=0.000 each). The differences in RNFL thickness in the average, superior, inferior, and temporal quadrants between MS-ON eyes and MS-NON eyes [(98.3±12.0), (115.5±18.2), (117.7±21.5), (72.0±15.0), (68.1±16.1)μm] were significant (P〈0.05 each), while the nasal quadrant did not show significant differences. Compared to control eyes, RNFL in the nasal and temporal quadrants in MS-NON eyes showed a sign
