摘要
目的分析玻璃体不全后脱离的光学相干断层扫描(optical coherence tomography,OCT)图像特征,探讨玻璃体不全后脱离与所引发的玻璃体视网膜病变的关系。方法对81例(86只眼)玻璃体不全后脱离患者进行眼科常规检查、B型超声检查和OCT检查,并对所获得的OCT图像进行分析,观察玻璃体视网膜界面的异常图像特征。结果27只眼显示特发性玻璃体黄斑牵引综合征;25只眼显示特发性黄斑前膜;25只眼显示后界膜牵拉导致特发性黄斑板层裂孔及全层黄斑裂孔形成;9只眼显示玻璃体后界膜与黄斑部及视盘周视网膜神经上皮层多处牵拉粘连。结论OCT能够直观的显示玻璃体不全后脱离与所引发的黄斑部视网膜病变的进展变化,并可进行定量、定性分析与鉴别诊断。
Objective To observe the characteristics of the images of optical coherence tomography（OCT） performed on the patients with uncompletely posterior vitreous detachment （PVD） Methods 81 patients （86eyes） with uncompletely PVD were underwent routine ophthalmic examination. B-scan ultrasonography and OCT examination. The Resuits of OCT images were analyzed. Results Idiopathic vitreomacular traction syndrome （IVTS） in 27 eyes, idiopathic macular epiretinal membranes （IMEM） in 25 eyes, laminar macular holes and macular holes in 25 eyes, The vitreous posterior membrane adhered traction with neurepithelial layer at macular and optic disc surrounding area in 9 eyes . Conclusions OCT can directly show the progress of the macula retinal disease with uncompletely PVD and be helpful in its diagnosis
