视网膜脱离手术前后黄斑区光学相干断层成像图形特征观察

目的 :观察孔源性视网膜脱离手术前后黄斑区光学相干断层成像 (OCT)的形态特征及临床应用价值。方法 :对 2 8例 2 8眼孔源性视网膜脱离PVRB级以下的患者手术前后黄斑区中心凹进行OCT检查 ,对其图像及与手术前后视力进行分析。结果 :根据 2 8例患者术前临床观察及OCT扫描图像可分为两组四型 ;术后OCT检查显示有 11例 (3 9 2 9% )患者视网膜下仍有微量积液 ;两组四型黄斑中心凹平均RNFL比较无显著性差异 (P >0 0 5 )。结论 :OCT作为一种高分辨率的在眼内获得活体组织横断面的检查仪器 ,能直观、清晰地显示视网膜脱离手术前后黄斑区视网膜横断面的形态特征 ,发现一些临床不易观察的眼底细微改变 ,如黄斑区视网膜神经上皮下微量的积液、视网膜的水肿、囊腔样改变等

The characteristics of the retinal detachment under optical coherence tomography

To investigate the clinical application of the optical coherence tomography (OCT) and the characteristics of retinal detachment in macular area before and after surgery under OCT. Methods:Comparative analysis was run on 28 eyes of 28 case s of retinal detachment (under the level of PVRB),based on the OCT images of the macular fovea centralis,and the visual acuities before and after operations.28 cases were divided into four types of two groups according to the clinical observation before operations and the images of OCT. Results:The OCT images showed that 11 cases (39.29%) had a little subretinal fluid after operations.It had no significant difference in the average RNFL of the macular fovea centralis among the four types of two groups (P>0.05). Conclusions:The outcomes confirmed that OCT is a valuable instrument for the clinical management of some retinal disorders.
