绝对期青光眼视网膜神经纤维层活体影像学观察   总被引:2,自引:0,他引:2  
尽管青光眼是多因素疾病,但最终均为视网膜神经节细胞的凋亡、变性和视神经的损害。Quigiey等的研究表明,青光眼患者的视网膜神经节细胞(RGC)丢失40%左右将出现临床可检测的视野损害。然而,临床绝对期青光眼视功能完全丧失时RGC是否完全丧失?本研究应用光学相干断层扫描仪(optic coherence tomograph,OCT)对绝对期青光眼的视网膜神经纤维层(retinal nerve fiber layer,RNFL)进行了定量观察,以间接了解RGC在绝对期青光眼患者的丢失情况。  相似文献

Objective To compare difference of the cross-sectional pathological imaging and quantitative measurement of central serous chorioretinopathy (CSC) between time-and fourier-domain optical coherence tomography (OCT). Methods Consecutive 26 patients (26 eyes) with unilaterial CSC were subsumed. Bilateral eyes of all the patients underwent time-and fourier-domain OCT. Horizontal and vertical line scanning and radial six-line scanning protocols were used for time-domain OCT examination; horizontal and vertical high resolution five-line scanning and macular cube scanning protocols were used for fourier-domain OCT examination. The characteristics of OCT images, retinal segmentation and the quantitative measurement were compared between these two methods. Results Fourier-domain OCT could yield the three-dimensional images of surface of inner limiting membrane (ILM) and RPE. The band of external limiting membrane (ELM) of normal subjects and CSC patients, and the inner segment and outer segment (IS/OS) of normal subjects could be clearly shown by fourier-domain OCT. However, the band of IS/OS disappeared in 65.4 % of the CSC patients. The outer boundary of retina was defined in front of the retinal pigmental epithelia (RPE) by fourier-domain OCT. The foveal thickness of normal subjects and CSC patients was (180. 50 ±12.69) and (158. 41 ± 34.20) μm, respevtively. The height of detachment of neuralepithelial layer was (245.84± 154.61) μm measured by fourier-domain OCT. The band of IS/OS of normalsubjects could be clearly shown by time-domain OCT. However, the band of IS/OS disappeared in 73.4%of the CSC patients, which showed no difference with fourier-domain OCT (Z=-0. 108, P=0. 914). Theouter boundary of retina was defined in front of the IS/OS band by OCT. The foveal thickness of normal subjects was (141.16±12.75) μm, which was thinner than that measured by fourier-domain OCT (t= 20. 671,P= 0. 000). The foveal thickness and the height of detachment of neural epithelial layer was (146.40± 36.28) μm and (240. 32±156. 82) μm measured by time-domain OCT, respectively, which showed no significant difference with which measured by fourier-domain OCT (t value was from 0. 026 to 1. 517, P value was from 0. 144 to 0. 980). Conclusions Fourier-domain OCT yields better visualization of intraretinal layers and more accurate definition of outer boundary of retina than time-domain OCT. Thus the measurements by fourier-domain OCT were more accurate. Moreover, three-dimensional images of CSC shown by fourier-domain OCT enable the comprehensive observation of pathological morphology and location.  相似文献

Objective To observe the features of the images of optical coherence tomograpy (OCT) in patients with traumatic macular hole (TMH), and detect the clinical significance of OCT. Methods Consecutive 74 patients (74 eyes) diagnosed with TMH by examinations of visual acuity, slit lamp, and direct or indirect ophthalmoscopy underwent optical coherence tomography (OCT), The analysis software of OCT was used to make the quantitative measurements of TMH. And the TMH were classified according to the morphological characteristics of the images of OCT. 50°color fundus photography was performed on the patients after OCT. The relationship of TMH with the average visual acuity, disease duration, average neuroepithelial thickness on the margin of hole, and the base diameter and the apex diameter of macular hole were retrospectively analyzed. Results The characterisctics of the images of 74 cases (74 eyes) of TMH were classified into 5 types: macular holes with symmetric edema of the neurosensory retina at the margin in 27 eyes (36.5%), macular holes with asymmetric edema of the neurosensory retina at the margin in 12 eyes (16.2%), macular hole with full-thickness defect of neurosensory retina without edema or detachment at the margin in 14 eyes (18.9 %), macular hole with localized detachment of the neurosensory retina at the margin without edema in 17 eyes (23.0 %), and macular hole with thinning neurosensory retina in 4 eyes (5. 4 %).There was no significant difference of visual acuity among different types of TMH (F=1. 574, P=0. 191).The visual acuity was positively related with the marginal retinal thickness (r=0. 342, P=0. 003), but not related to age, diameter of macular hole or the disease duration(r value was from-0. 022 to-0. 134, P value was from 0. 863 to 0. 261). The disease duration of Type IV TMH was shorter than that of other TMH types. In the patients with the disease duration over 90 days, Type I TMH was predominant. The average retinal thicknesses at the margin of the hole showed significant differences among different TMH types (F= 13.921, P= 0.000). Conclusions TMH could be divided into 5 types according to the characteristics of images of OCT; the clinical characteristics of different types of TMH varies.  相似文献

目的:探讨影响重度闭合性肾损伤治疗决策的因素,最大限度保存肾功能并降低死亡风险。方法:回顾性分析76例重度闭合性肾损伤患者的临床资料,采用χ2检验、t检验及多因素Logistic回归分析方法分析各临床因素对治疗决策的影响。结果:76例重度闭合性肾损伤患者中,Ⅳ级53例,Ⅴ级23例。与非手术组比较,手术组收缩压(P=0.001)、舒张压(P=0.003)、血红蛋白水平(P=0.039)更低,心率更快(P=0.016),输血率更高(P0.001),Ⅴ级肾损伤所占比例更高(P0.001),肾周出血弥漫更明显(P=0.019)。在多因素Logistic回归分析中,肾损伤分级(OR=20.289,P=0.009)和心率(OR=1.08,P=0.027)是手术治疗的独立危险因素。非手术组中,微创治疗组患者血红蛋白更低(P0.001),输血率更高(P=0.001),肾周血肿(PRD)更大(P=0.026)。受试者工作特征曲线(ROC)显示需要微创治疗的肾周血肿的最佳临界距离为3.1cm。在多因素回归分析中,PRD≥3.1cm(OR=73.547,P=0.002)是微创干预的唯一预测因素。结论:非手术治疗可用于重度闭合性肾损伤患者,其中PRD是介入干预治疗的重要指标,而肾损伤分级和心率的变化是手术探查的独立危险因素。  相似文献
