目的 探讨玻璃体黄斑牵引综合征的三维频域相干光断层扫描(OCT)图像特征.方法 回顾性系列病例研究.收集18例经三维频域OCT检查确诊的玻璃体黄斑牵引综合征患者的临床资料进行回顾性分析,着重观察其三维频域OCT检测图像特征.根据频域OCT定量检测的玻璃体与黄斑区视网膜附着粘连的范围,将玻璃体黄斑牵引综合征分为局灶型和宽大型两类.运用线性回归法分析所有患者的最小分辨角对数视力(logMAR视力)与黄斑中心凹部视网膜厚度的关系.结果 玻璃体黄斑牵引综合征患者的频域OCT检测图像清晰,其病变特征明显.18例患者中,病变呈局灶型14例,宽大型4例;合并黄斑前膜8例,合并黄斑全层裂孔2例,合并黄斑板层裂孔2例.18只眼的logMAR视力为0.15～1.22,其黄斑中心凹视网膜厚度为275～899 μm,经线性回归分析,显示所有患者的logMAR视力与黄斑中心凹的视网膜厚度呈中度线性正相关(r=0.616,P=0.007).结论 三维频域OCT检测可以直观地显示眼底病变三维结构,对玻璃体黄斑牵引综合征患者的诊断和随访具有重要作用.     

闭合性眼外伤致黄斑裂孔的光相干断层扫描图像分析

目的 观察外伤性黄斑裂孔的光相干断层扫描（OCT）形态特征及其临床意义。方法 对采用国际标准视力表、裂隙灯显微镜、直接或间接检眼镜、三面镜检查确诊的74例闭合性眼外伤致黄斑裂孔患者74只眼进行光相干断层扫描（OCT）检查。利用OCT分析软件对外伤性黄斑裂孔进行定量测量,并根据OCT图像特征对外伤性黄斑裂孔进行分型。OCT检查完毕用Topcon眼底照相机进行眼底50°彩色照相。回顾分析患者黄斑裂孔与平均视力、病程、孔缘神经上皮层厚度、裂孔底径、孔径之间的相互关系。结果 74只眼的OCT图像特征可分为5种类型。其中,黄斑裂孔伴神经上皮层对称性水肿27只眼,占36.5%;黄斑裂孔伴神经上皮层不对称性水肿12只眼,占16.2%;单纯性黄斑裂孔14只眼占18.9%;黄斑裂孔伴神经上皮层局限性脱离17只眼,占23.0%;黄斑裂孔伴神经上皮层变薄4只眼,占5.4%。不同类型的黄斑裂孔之间视力比较,差异无统计学意义（F=1.574, P=0.191）;其视力与孔缘平均神经上皮层厚度呈正相关 （r＝0.342,P＝0.003）,与致伤时间、年龄、裂孔直径无明显相关关系（r＝-0.022～-0.134,P＝0.863～0.261）。黄 斑裂孔伴神经上皮层局限脱离者,病程较其它各型黄斑裂孔者病程短;病程90 d及以上的患者中,黄斑裂孔伴神经上皮层对称性水肿最多。各型黄斑裂孔的孔缘神经上皮层厚度之间比较,差异有统计学意义（F=13.921, P=0.000）。结论 外伤性黄斑裂孔可根据OCT形态特征分为5种类型,不同类型的外伤性黄斑裂孔临床特征存在差异。     

特发性黄斑裂孔的超声检查与光相干断层扫描结果对比分析

特发性黄斑裂孔(IMH)为黄斑中心凹前切线方向玻璃体皮质的收缩造成Mtiller细胞锥的破裂,进而导致中心凹全层的缺损和裂孔前混浊物的形成.病理学显示其周围有神经上皮层的脱离或层间水肿,或伴有视网膜前膜,部分可观察到玻璃体皮质牵拉孔边,而裂孔盖膜常翘起于孔的一边或漂浮在邻近视网膜的玻璃体腔中[1,2].     

闭合性眼外伤致黄斑裂孔的光相干断层扫描图像分析

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.
