简介:目的探讨一种规范化的的高度近视白内障超声乳化方式,总结手术注意点。方法选取高度近视白内障患者91例(91眼)均予以超声乳化联合人工晶体植入术治疗并总结。结果所有病例的术后裸眼视力均优于术前裸眼视力。术后第1天裸眼视力≥0.2共72眼(79.12%),≥0.5共37只眼(40.66%);术后3月裸眼视力≥0.2共85只眼(93.41%),≥0.5共42只眼(46.15%)。最佳矫正视力≥0.2共89只眼(97.80%),最佳矫正视力≥0.5共72只眼(79.12%)。术前散光度平均1.10D±0.78D,术后3月散光度平均1.25D±0.72D。术后散光度与术前散光度比较,差异无显著性(t=1.166,P=0.261)。无瞳孔严重变形、视网膜脱离、囊样黄斑水肿、瞳孔夹持、青光眼以及顽固性葡萄膜炎等并发症。结论低能量,高负压,低灌注,连续环形撕囊,双手劈核技术对于高度近视白内障患者更加安全有效。
简介:目的对改良翼状胬肉手术方法进行安全性评估的研究。方法188例翼状胬肉患者随机分为实验组和对照组。实验组接受改良方法进行翼状胬肉手术。对照组按照《眼科手术图谱》传统翼状胬肉切除术方法进行手术。记录所有患者手术时间、术后角膜上皮修复时间。术后每周随访,记录术后1周、2周、3周、4周时结膜充血情况及结膜充血完全消退时间。随访3个月,记录发生角巩膜溃疡、结膜肉芽以及翼状胬肉复发的病例数。结果实验组有96人完成随访,对照组有92人完成随访。实验组患者角膜上皮修复时间为2.42±0.68天,对照组为4.27±1.05天,P〈0.05,差别有统计学意义;实验组结膜充血评分术后1周、2周、3周、4周时分别为3.31±0.47、2.76±0.74、1.89±0.860.94±0.70,对照组分别为3.84±0.37、3.58±0.67、2.93±0.71、1.85±0.78,两两比较P〈0.05,差别有统计学意义。结膜充血消退时间实验组为5.15±0.92周,对照组为7.20±1.08P〈0.05,差别有统计学意义。实验组未发生结膜肉芽,对照组为14例,P〈0.05,差别有统计学意义。实验组发生角巩膜溃疡4例、复发4例,对照组为7例、5例,P〉0.05,差别无统计学意义。结论改良的翼状胬肉手术方法在术后角膜上皮修复时间、术后结膜充血程度、结膜充血消退时间、结膜肉芽发生率上忧于传统手术方法,差别有统计学意义。在角膜溃疡发生率、翼状胬肉复发率上改良手术方法与传统手术差别无统计学意义。
简介:目的观察翼状胬肉切除联合自体结膜移植术中术眼结膜瓣不同取瓣位置对疗效的影响。方法将80例(80眼)单侧原发性翼状胬肉患者分为A、B2组,分别行翼状胬肉切除+自体结膜移植术,其中A组于术眼上方球结膜处取结膜瓣,B组于术眼下方球结膜处取结膜瓣。比较2组患者术后1周、2周、1个月、3个月术眼刺激症状、角膜结膜愈合情况,结膜瓣存活情况及术后3个月胬肉复发情况。结果两组患者术后1周、2周、1个月、3个月术眼刺激症状、角膜结膜愈合情况,结膜瓣存活情况及术后3月胬肉复发情况未见统计学差异(P>0.05)。结论翼状胬肉切除联合自体结膜移植术中术眼球结膜下方取结膜瓣与上方取瓣疗效相同。且下方取瓣可避免上方球结膜区瘢痕化,为今后可能的内眼手术留有余地。
简介:目的探讨改良式小梁切除术联合丝裂霉素C治疗青光眼的临床疗效。方法应用改良式小梁切除术治疗42例(64眼)各型青光眼,术中一次性使用0.4mg/ml丝裂霉素C,术后随访6~12月,观察其临床疗效及其并发症。结果术后1月检查,58眼(90.6%)术后视力有不同程度的提高;术后1周测眼压,所有病例眼压均有不同程度的下降,有48眼(75.0%)眼压低于21mmHg,术后6月测眼压,54眼(84.6%)低于21mmHg;末次随访时,56眼(87.5%)形成弥散扁平的功能性滤过泡,8眼(12.5%)为非功能性滤过泡;总手术成功58眼(90.6%),其中完全成功54眼(84.4%),条件成功4眼(63%),失败6眼(9.4%)。术后主要并发症为:角膜水肿5眼,前房渗出4眼。讨论改良式小梁切除术联合丝裂霉素C治疗青光眼,可有效地减少青光眼术后滤过道瘢痕的形成,充分降低眼压。该方法不需要特殊设备,手术时间短、损伤小,并发症少,手术效果好,是一种安全、有效的治疗青光眼方法。
简介:目的研究非接触式角膜内皮镜中参与分析的细胞数(NC)对测量结果重复性的影响。方法收集2011年3月至2016年3月到我院诊治并在同一时间行2次以上(含2次)非接触式角膜内皮镜测量的患者,其测量结果包括中央角膜厚度(CCT)、内皮细胞密度(ECD)、平均细胞面积(ACS)、细胞面积变异系数(CV)和六边形细胞百分比(HEX%),排除NC=0的结果,〉2次测量的患者,选择NC最大的2组结果,以每位患者所得的2组结果中NC较小者(NCmin)为分组依据,10个细胞为一个等级,获得(NCmin〈10、10~20……90~100、≥100)11个组段,采用组内相关系数(ICC)及其95%置信区间(95%CI)对各组段内2组数据的重复性进行评估,并对ICC进行F检验,检验水准α=0.05。结果各组段CCT的ICC均〉0.9,且95%CI下限在0.75以上;ECD和ACS的ICC,当NC≥100时,均〉0.9,且95%CI下限在0.75以上,当NC≥50时,均〉0.75;CV的ICC,当NC≥90时,〉0.75,其余组段均〈0.75;HEX%的ICC,当NC≥100时,〉0.75,其余组段均〈0.75。结论CCT测量结果的重复性不受NC限制;分析ECD和ACS时,NC应在50以上,当NC≥100时,测量结果的重复性最佳;分析CV和HEX%时,NC应分别在90和100以上。
