目的:研究后囊膜混浊(posterior capsular opacity,PCO)及其治疗对使用谱域光学相干断层扫描(spectral domain optical coherence tomography,SD-OCT)测量视网膜神经纤维层(retinal nerve fiber layer,RNFL)厚度的影响。方法:使用SD-OC... 目的:研究后囊膜混浊(posterior capsular opacity,PCO)及其治疗对使用谱域光学相干断层扫描(spectral domain optical coherence tomography,SD-OCT)测量视网膜神经纤维层(retinal nerve fiber layer,RNFL)厚度的影响。方法:使用SD-OCT测量50例接受Nd:YAG激光后囊膜切开术患者术前和术后RNFL厚度。通过信噪比(signal to noise ratio,SNR)等级,将患者分为组1(SNR 3和4)、组2(SNR 5和6)及组3(SNR 7和8)。对侧眼作为对照组。结果:接受了Nd:YAG激光后囊膜切开术的眼BCVA、SNR和RNFL均值显著增加。组1和组2激光治疗前后BCVA、SNR和RNFL均值显著不同。尽管组3中患者治疗前后BCVA和SNR均值显著不同,RNFL厚度在治疗前后没有显著差异。结论:PCO对OCT图像质量有影响。所有接受后囊膜切开术的患者,术后SNR较术前有所改善。治疗前SNR7在以下的患者中,RNFL厚度在患者接受Nd:YAG激光后囊膜切开术后显著提高。 展开更多

AIM:To measure the central choroidal thickness(ChT)in children and adolescents with anxiety disorders.METHODS:Totally 41 anxiety patients(8-16 y)and 35 healthy controls(age-matched)were evaluated.Complete ophthalmic examination was performed.Inclusion criteria were best corrected visual acuity≥20/20,normal intraocular pressure(IOP;10-21 mm Hg),and no systemic or ocular diseases according to history.The diagnosis of psychiatric disorders was determined using Schedule for Affective Disorders and Schizophrenia for School Aged Children Present-Lifetime Version(K-SADS-PL).Enhanced depth imaging optical coherence tomography(EDI-OCT)was used to measure the central ChT.RESULTS:The mean age was 12.18±3.24 y in the patient group and 12.86±3.15 y in the control group.Age and gender distribution of the two groups was similar.Central ChT mean value was 353.26±31.9μm in anxiety patients while 318.75±60.9μm in the control group.Mean central ChT was statistically significantly higher in the children and adolescents with anxiety disorders than healthy controls(P=0.002).CONCLUSION:The children and adolescents with anxiety disorders have significantly thicker central ChT than controls.In the larger sample,longitudinal studies will contribute to the use of choroidal differences as a clinical marker for monitoring anxiety disorders. 展开更多
