摘要:

目的 分析鞍结节脑膜瘤患者的视盘参数特征及视盘周围视网膜神经纤维层(pRNFL)厚度的变化。设计 回顾性病例系列。 研究对象 2010年7月至2011年12月北京天坛医院鞍结节脑膜瘤患者40例(80眼)、正常对照40例(80眼)和青光眼患者40例(80眼)。方法 采用眼底照相和相干光断层扫描(OCT)测量视盘及不同象限pRNFL厚度,比较鞍结节脑膜瘤患者与正常对照组和青光眼组的视盘参数及pRNFL厚度,分析视盘参数改变与肿瘤大小的相关性。主要指标 视盘形态、视盘面积、杯盘面积比、水平杯盘比、垂直杯盘比、盘沿面积、视杯面积,视杯体积和不同象限pRNFL厚度。结果 鞍结节脑膜瘤组的杯盘面积比、水平杯盘比、垂直杯盘比、视杯面积和视杯体积与正常对照组相比均明显增大,而盘沿面积明显减小(P均=0.000);且杯盘面积比、水平杯盘比、盘沿面积和盘沿体积与青光眼组相比均较大,而垂直杯盘比、视杯面积和视杯体积较青光眼组明显减小(P均=0.000)。肿瘤组视盘周围不同象限pRNFL厚度分别为上方颞侧(124.022±26.100)μm,上方鼻侧(105.856±23.410)μm,鼻侧上方(75.784±19.260)μm,鼻侧下方(65.983±15.708)μm,下方鼻侧(105.915±25.526)μm,下方颞侧(133.591±24.429)μm,颞侧下方(76.592±19.679)μm,颞侧上方(77.352±26.100)μm,与正常对照组相比差异均具有统计学意义(P均<0.05);与青光眼组相比上方鼻侧象限不具有统计学意义(P=1.114),其余象限均具有统计学意义(P均<0.05)。鞍结节脑膜瘤盘沿体积与肿瘤大小相关(r=0.492,P=0.011)。结论 鞍结节脑膜瘤视盘形态表现为颞侧变窄、颜色变淡,pRNFL厚度与正常人群比较下方鼻侧变薄最明显,与青光眼组相比除上方鼻侧外其他各象限均变薄,下方颞侧最明显。

Abstract:

Objective To observe the characteristics of optic disc parameters and the change of peripapillary retinal nerve fiber layer (pRNFL) thickness in the patients with tuberculum sellae meningiomas. Design Retrospective case series. Participants The clinical data were collected in Tiantan Hospital from July 2010 to December 2011, which involved 40 patients (80 eyes) with tuberculum sellae meningiomas, 40 normal controls(80 eyes) and 40 glaucoma patients (80 eyes). Methods A total of 40 cases with tuberculum sellae meningiomas received the examination of fundus photography, pRNFL and optic disc parameters measurement by OCT, compared with the control group and glaucoma group. The relationship of optic disc parameters and tumor size were analysised. Describe the morphological characteristics of nuroretinal rim of optic discs (superior, S; nasal, N; inferior, I; temporal, T). Main Outcome Measures Rim volume, cup/disc(C/D) area ratio, horizontal C/D ration, vertical C/D ratio, rim area, cup area, cup volume and pRNFL. Results Optic disc parameters such as cup volume, optic disk area, C/D area ratio, horizontal C/D ratio, vertical C/D ratio, rim area, cup area in tumor group were bigger than in the normal group, rim volume were smaller than in the normal group (all P=0.000); C/D area ratio, horizontal C/D ratio, rim area, rim volume in the tumor group were bigger than in the glaucoma group, vertical C/D ratio, cup area, cup volume were smaller than in the glaucoma group (all P=0.000); The thickness of pRNFL in tumor group was 124.022±26.100 μm in ST, 105.856±23.410 μm in SN, 75.784±19.260 μm in NU, 65.983±15.708 μm in NL, 105.915±25.526 μm in IN, 133.591±24.429 μm in IT, 76.592±19.679 μm in TL, 77.352±26.100 μm in TU respectively, which were all significantly decreased compared with the thicknesses of pRNFL in normal group (all P<0.05). There was no significant differrence in SN (P=1.114) but significantly decreased in the other quadrants compared with the thicknesses of pRNFL in normal group (all P<0.05). The rim volume in tuberculum sellae meningioma evidently showed correlations with tumor size (r=0.492, P=0.000). Conclusion The features of optic disc parameters in the tuberculum sellae meningiomas shown as the temporal neuroretinal rim become narrow and pale;  compared with the normal control, the pRNFL thickness showed significant thiner in IN section; compared with glaucoma group, the except for SN region, other regions were significantly thiner, especially in IT section.
