简介:目的:探讨外伤性巩膜层间囊肿的切除及其联合手术方法。方法:回顾性总结17例确诊为外伤性巩膜层间囊肿的诊治情况。17例均有角巩膜裂伤及手术史。其中14例伴有继发性青光眼。手术采用切除巩膜层间囊肿联合异体巩膜移植术,对伴有难治性青光眼者同时行抗青光眼手术治疗。结果:17例中14例囊肿1次治愈,1例术后有脉络膜脱离合并出血,最终眼球萎缩,1例术后1a囊肿复发,1例术后1mo眼压失控,植片隆起,再次手术,随诊期间未见复发。随诊时间:2~30(平均12.3)mo。结论:彻底切除囊肿联合异体巩膜移植术对巩膜层间囊肿的疗效显著,复发率低。对于继发性青光眼者,因其眼前段损伤及粘连严重,多为难治性青光眼,以睫状体光凝或冷冻治疗为宜。
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:观察结膜瓣遮盖联合虹膜嵌顿术治疗全层感染真菌性角膜炎的疗效。方法:分析2005-03/2011-04在邢台眼科医院行结膜瓣遮盖+虹膜嵌顿术的深部真菌性角膜炎患者26例26眼,全部的病灶的范围均〈(5×5)mm2,角膜刮片检查真菌菌丝全部为阳性;前房积脓(+),病灶均较致密,术前不能确定病灶累及深度;在术中,当病灶剖切至接近后弹力层深度时,根据临床特点,对于病灶累及角膜全层,但直径≤1mm的患者,人为在残余病灶的近周边处刺透角膜,造成角膜穿孔,自角膜穿孔或破溃处注吸前房积脓和抛光内皮斑后,将相邻近的虹膜嵌顿在角膜穿孔处,并用缝线固定1~2针,最后行结膜瓣遮盖术,尽量保持水密,术后继续给予抗真菌治疗并密切观察。结果:患者26例中有5例在病灶剖切中自行破溃,3例在病灶剖切中不慎切透,18例角膜基质床在剖切过程中完整;结膜上皮恢复时间为13.44±2.21d;24例感染得到控制,成功率为92%;2例因感染未控制而改为角膜移植术,最终控制感染。结论:结膜瓣遮盖联合虹膜嵌顿术是治疗小范围的全层真菌性角膜炎的有效方法,它可以控制感染,为以后的增视手术创造条件,适合在基层医院开展。
简介:目的:探讨原发性开角型青光眼(primaryopenangleglaucoma,POAG)早期上下半视盘周围视网膜神经纤维层(retinalnervefiberlayer,RNFL)的变化特征。方法:临床观察研究,研究对象为2012-05/2014-05在我院门诊确诊为原发性开角型青光眼早期患者30例39眼和健康成人20例40眼,使用Humphrey视野计和光学相干断层成像术(opticalcoherencetomography,OCT)检查,分别记录视野平均缺损(meandefect,MD)、青光眼半视野检测(glaucomahemifieldtest,GHT)、眼压、C/D比值及视盘周围FNFL厚度。使用SPSS18.0统计软件对测量值进行统计分析,计量资料组间比较采用t检验。结果:两组上半视盘各钟点位的RNFL厚度减去下半视盘相对应钟点位的RNFL厚度,两组间比较,仅上鼻-下鼻的差值具有统计学意义(t=2.526,P=0.014),其余上下半视盘相对应钟点位RNFL厚度的差值比较,两组间均无统计学意义(均为P〉0.05)。结论:原发性开角型青光眼早期上下半视盘周围RNFL存在不对称性变化,上鼻部位(右眼1颐00位,左眼11颐00位)的RNFL较下鼻部位(右眼5颐00位,左眼7颐00位)的RNFL更容易受损变薄。

简介:目的:利用频域三维相干光学断层扫描(threedimensionalfrequencydomaincoherentopticaltomography,3D-OCT)评估准分子激光原位角膜磨镶术(laserinsitukeratomileusis,LASIK)对视网膜神经纤维层厚度(retinalnervefibrelayerthickness,RNFLT)的影响。方法:对83例83右眼接受LASIK治疗的受试者分别于术前及术后1d;1wk;1,3mo行3D-OCT检查,测量视乳头上方、下方、鼻侧、颞侧及12个钟点位RNFLT,利用重复测量方差分析及配对t检验对术前及术后的数据统计学处理。结果:术前及术后各时间点行重复测量方差分析显示,视乳头下方、颞侧、5:00~11:00位RNFLT均值无显著差异(P〉0.05),而视乳头上方、鼻侧、1:00~4:00位、12:00位RNFLT有显著差异(P〈0.05);进一步对术前及术后各时间点视乳头上方、鼻侧、1:00~4:00位、12:00位RNFLT分别行配对t检验得出,术后1d时视乳头上方、鼻侧及1:00~4:00位、12:00位RNFLT较术前变薄,差异有统计学意义(P〈0.05),术后1wk;1,3mo时以上各方位RNFLT较术前比较均无统计学差异(P〉0.05)。同时表明RNFLT变薄与屈光度及激光时间成正相关。结论:LASIK术后早期上方及鼻侧RNFLT变薄,但术后1wk恢复至正常水平,LASIK手术对RNFLT无长远影响。
