摘要
目的:观察老年性白内障超声乳化术后黄斑病变的光学相干断层扫描(optical coherence tomogra-phy,OCT)图像特征。方法:对年龄在60岁以上的50例超声乳化白内障术后视力不良的患者进行OCT检查,观察其图像特征。结果:15眼表现为黄斑水肿,视网膜厚度增加;12眼表现为黄斑区视网膜神经上皮层变薄;9眼表现为黄斑区增生膜形成,其中8眼伴有神经上皮水肿增厚;9眼表现为黄斑区裂孔形成,其中6眼为全层裂孔,3眼为板层裂孔;5眼黄斑区神经上皮层未发现明显异常,其中2眼视网膜色素上皮局部连续性中断。结论:OCT技术提供了黄斑区视网膜解剖结构改变的重要信息,在老年性白内障超声乳化术后黄斑病变的早期确诊中发挥重要的作用。
· AIM: To observe the characteristics of optical coherence tomography (OCT) of the macular disease after phacoemulsification on senile cataract patients.· METHODS: A total of 50 senile cataract patients aged over 60 with poor visualacuity after phacoemulsification were examined by OCT.· RESULTS: In all the 50 cases, macular edema was found in 15 eyes, and the retinal neuroepithelium in macular area was thinner than the normal in 12 eyes. Secondary premacular membrane was found in 9 eyes in which 8 eyes had hydropic thickening of neuroepithelium. Macular hole could be seen in 9 eyes including full layers macular hole in 6 eyes, and lamellar macular hole in 3 eyes. The macularneuroepithelium was normal in 5 eyes, including the discontinued retinal pigmentepithelia in 2 eyes.· CONCLUSION: OCT can display the morphological characteristics and anatomicalchanges of retina in macular area directly and visually, and it is potentially useful as a new and noninvasive diagnostic technique for the examination of macular diseases after phacoemulsification in senile cataract patients.·
