简介:目的探讨翼状胬肉切除术后并发角巩膜病变的可能原因及相应治疗对策.方法对2009年12月至2013年5月期间于安徽省第二人民医院就诊的6例(6只眼)翼状胬肉切除术后并发角巩膜病变患者的病史、相关检查和治疗等资料进行回顾性分析.结果6例翼状胬肉患者术后并发角巩膜病变,其中2例发生角膜溃疡,分别为真菌性角膜炎和病毒性角膜炎所致;1例患者胬肉病灶切除位置烧灼引起巩膜变薄、溶解;1例患者术后发生巩膜病变,检查发现免疫指标升高;1例患者术后发生角膜脓肿,检查发现结膜囊G+杆菌阳性;1例患者有高血压,脑梗塞,术后发生角膜溃疡.结论单纯胬肉切除、术中烧灼过度、全身抵抗力下降、自身免疫功能异常,不规范用药、术后护理不当,是翼状胬肉并发角巩膜病变的主要原因.注重全身因素影响、加强术后眼部卫生护理,翼状胬肉切除联合角膜缘干细胞移植术后及时复查治疗可避免术后严重并发症.

简介:目的:探讨4~10岁不同近视程度儿童视神经纤维层(retinalnervefiberlayer,RNFL)厚度改变。方法:收集2012-01/2014-05于我院就诊的高度近视儿童12例(屈光度逸-6.00D),中度近视儿童14例(-3.00D≤屈光度〈-6.00D),轻度近视儿童14例(0D≤屈光度〈-3.00D),对所有患儿完善RNFL厚度测量,并进行组间对比。结果:高度近视组平均RNFL厚度为102.36±10.33μm,中度近视组平均RNFL厚度为106.52±9.46μm,轻度近视组平均RNFL厚度为112.66±9.79μm。高度近视组较轻度近视组儿童平均RNFL厚度变薄,差异具有统计学意义(P〈0.05);高度近视组与中度近视组、中度近视组与轻度近视组相比,RNFL差异无统计学意义(P〉0.05);在下方象限,高度近视组与轻度近视组,中度近视组与轻度近视组RNFL对比差异具有统计学意义(P〈0.05),其余三组各象限对比差异均无统计学意义。结论:在高度近视患者平均R较轻度近视组明显变薄,且在下方象限高度近视与中度近视组较轻度近视组均明显变薄。在对近视儿童的诊疗过程中,我们应当完善近视RNFL厚度检查辅助诊断,可为近视儿童的观察及随访提供客观指标。
简介:目的:分析总结2.5g/L马来酸噻吗洛尔眼液(timolol)对准分子激光原位角膜磨镶术(laserinsitukeratomileusis,LASIK)后屈光回退的治疗效果。方法:选取我院准分子中心2007—08/2008—08接受LASIK手术病例1400例2650眼,随访0.5a以上,发生屈光回退者有53例66眼,按手术时间随机分为两组,试验组使用2.5g/L马来酸噻吗洛尔眼液进行治疗,对照组使用1g/L玻璃酸钠眼液进行治疗,两组治疗时间均为2wk,治疗结束后将试验组与对照组进行分析比较(视力提高行数)。结果:试验组视力提高-1~4(平均1.45±1.09)行,对照组视力提高.2~2(平均0.61±0.86)行,行成组t检验显示,两组差异有统计学意义(t=3.500,P〈0.05)。结论:马来酸噻吗洛尔眼液2.5g/L对LASIK术后屈光回退具有显著疗效。
简介:目的:探讨穿透性角膜移植的主要病因、疗效及并发症。方法:回顾性分析2011-01/2013-06于我院行穿透性角膜移植术的患者150例150眼。结果:病因:角膜白斑99眼(66%),角膜变性18眼(12%),角膜溃疡15眼(10%),角膜内皮失代偿10眼(6.7%),圆锥角膜8眼(5.3%)。疗效:植片透明110例(73.3%)。视力≤0.05者42例(28%),0.05〈视力≤0.3者60例(40%),视力〉0.3者48例(32%)。并发症:主要并发症为免疫排斥反应28例(18.7%)。结论:穿透性角膜移植是治疗角膜疾病致盲的重要有效手段,但术后排斥反应仍是影响手术成功的主要因素。
