Methods:.Case report. Results:.A 3-year-old girl presented with redness and mild photophobia in the left eye accompanied by corneal ulcer, hypopyon,.and corneal neovascularization..Corneal sensation was reduced bilaterally..She exhibited an absence of normal response to painful stimuli..She also had extensive ulceration of the lateral borders and tip of the tongue. The left corneal biopsy revealed negative cultures for bacteria and fungi. She was treated with human amniotic membrane transplantation in the left eye. The response to treatment was good. Conclusion:.This is the first case of CCA reported in China. CCA is often misdiagnosed as infectious keratitis..Amniotic membrane transplantation is effective in repairing the severe corneal ulcer which may be associated with CCA.展开更多
目的:研究儿童配戴RGP镜片后角膜敏感性的变化。方法:采用问卷的形式收集基本信息,应用Cochet and Bonnet aesthesiometer测量67例134眼角膜敏感性,按照不同分组进行比较分析。结果:儿童戴镜1～12mo组,戴镜1～5a组中央部和下方角膜敏感...目的:研究儿童配戴RGP镜片后角膜敏感性的变化。方法:采用问卷的形式收集基本信息,应用Cochet and Bonnet aesthesiometer测量67例134眼角膜敏感性,按照不同分组进行比较分析。结果:儿童戴镜1～12mo组,戴镜1～5a组中央部和下方角膜敏感性明显下降(中央P=0.000,下方P=0.002),而2组之间的差异无显著意义(中央P=0.997,下方P=0.056)。儿童戴镜1～5a组颞侧,鼻侧,上方角膜敏感性明显下降(颞侧P=0.000,鼻侧P=0.000,上方P=0.001),戴镜1～5a组与戴镜1～12mo组(颞侧P=0.133,鼻侧P=0.125,上方P=0.205),未戴镜组与戴镜1～12mo组(颞侧P=0.06,鼻侧P=0.200,上方P=0.207),差异均无显著意义。儿童与成年人分别配戴RGP镜片1～12mo和1～5a,中央角膜敏感性无显著差异(1～12moP=0.343,1～5aP=0.105)。结论:RGP镜片对于儿童和成人的中央角膜敏感性的影响是相似的。但由于儿童自身的特点,为儿童验配RGP仍应慎重。展开更多
目的:针对配戴不同类型接触镜后角膜敏感性变化的机制进行研究,以期对接触镜的临床验配和并发症的早期发现与处理提供帮助。方法:采用问卷的形式收集基本信息,应用Cochet and Bonnet aesthesiometer测量49例98眼角膜敏感性,按照不同分...目的:针对配戴不同类型接触镜后角膜敏感性变化的机制进行研究,以期对接触镜的临床验配和并发症的早期发现与处理提供帮助。方法:采用问卷的形式收集基本信息,应用Cochet and Bonnet aesthesiometer测量49例98眼角膜敏感性,按照不同分组进行比较分析。结果:分别配戴RGP和软镜,戴镜1～12mo组,1～5a组中央部角膜敏感性均较未戴镜组明显下降(P=0.000),而二组之间差异无显著意义(RGP镜片P=0.921,软镜P=0.685);配戴Dk为36和82的RGP镜片1～12mo,二者差异无显著意义(P=0.263);分别配戴RGP镜片和软镜1～12mo,1～5a,两组中央角膜敏感性差异无显著意义(1～12mo组P=0.263,1～5a组P=0.366)。结论:配戴接触镜导致的角膜敏感性下降是多种机制共同作用的结果,不同类型镜片的机制略有不同。展开更多
