目的 :探讨光学相干断层扫描图像在分析白内障术后低视力中的应用。方法 :对术后矫正视力低于 0 5的 48例 (4 8眼 )病人行OCT检查 ,分析其结果。结果 :48眼中黄斑水肿 2 1眼 ,老年性黄斑变性 8眼 ,糖尿病眼底病变 5眼 ,视网膜中央静脉栓塞 2眼 ,视神经萎缩 2眼 ,视网膜脱离 1眼 ,黄斑板层裂孔 2眼 ,7眼未发现异常。结论 :OCT是一种新的、非接触的诊断技术 ,在白内障术后低视力原因分中 ,它能快速准确地检查出低视力的原因 ,并能客观的检测临床治疗效果。
Objective: To investigate the application of optical coherence tomography in the analysis of low vision after cataract surgery. Methods: OCT examination was performed on 48 patients (48 eyes) with postoperative corrected visual acuity of less than 0 5, and the results were analyzed. Results: There were 21 macular edema in 48 eyes, 8 eyes with age-related macular degeneration, 5 eyes with diabetic retinopathy, 2 eyes with central retinal vein embolization, 2 optic atrophy, 1 retinal detachment, 2 macular hole and 7 eyes without retinal detachment Found abnormal. Conclusion: OCT is a new non-contact diagnostic technique. It can quickly and accurately detect the cause of low vision and objectively measure the clinical effect of low vision after cataract surgery.
