  • 简介:目的探讨单纯泪道探通与泪道探通联合洛美沙星凝胶治疗婴幼儿泪道阻塞的不同效果.方法将100例泪道阻塞患儿按来院顺序随机分成A组与B组各50例,A组行泪道探通联合洛美沙星凝胶治疗,B组行单纯泪道探通.比较2组疗效.结果2组患儿实施治疗后差异显著(p<0.05),泪道探通联合洛美沙星凝胶治疗优于单纯泪道探通.结论泪道探通联合洛美沙星凝胶填充治疗婴幼儿泪道阻塞能保持泪道正常生理结构,更好的巩固探通后的效果,防止细菌再生,降低二次阻塞的发生,值得推广.

  • 简介:目的探讨玻璃体腔注射雷珠单抗辅助23G玻璃切割治疗增殖期糖尿病视网膜病变的优质护理。方法通过对28例28眼采用玻璃体腔注射雷珠单抗辅助玻璃切割治疗糖尿病患者并发视网膜增殖期病变存在的主要护理问题,针对患者治疗各阶段,责任护士提供全程、连续、系统的优质护理服务,加强护患沟通,提高护理质量,缩短手术时间,减少并发症的发生。结果24眼一次性手术复位成功(85.7%)术后三个月取出硅油,其中有4例伴有晶状混浊的同时行晶状超声乳化联合人工晶体植入;4例硅油填充下仍然存在下方局限性视网膜增殖,术后三个月取出硅油再次切割增殖膜然后注入C3F8气体填充,随访至气体完全吸收,视网膜复位。结论对玻璃体腔注射雷珠单抗辅助23G玻璃切割治疗增殖期糖尿病视网膜病变的患者提供优质护理,可缩短手术时间,减少并发症的发生,提高病人及家属的满意度,提升患者的康复效果,是手术取得成功的关键因素。

  • 简介:目的观察泪道探通后氟尿嘧啶应用联合鼻泪管中逆行植入球头硅胶管治疗慢性泪囊炎的临床疗效。方法从门诊就诊的泪道阻塞患者中,选取泪点泪小管均通畅的慢性泪囊炎患者42例(56只眼),随机分为实验组与对照组,治疗组采用先泪道探通扩张,并将氟尿嘧啶溶液浸入阻塞创面,后鼻腔逆行植入球头硅胶管治疗,对手术疗效进行分析。对照组则不采用氟尿嘧啶干预措施,其余治疗与对照组相同。两组患者均于术后3个月拔管。结果拔管后随访3~12个月,治疗组21例(29只眼)中有效25只眼,泪道冲洗通畅无分泌物,2只眼冲洗欠通畅无分泌物,2眼泪道冲洗仍阻塞,治愈率86.2%。对照组21例(27只眼)中有效17只眼,泪道冲洗通畅无分泌物,4只眼冲洗欠通畅无分泌物,6眼泪道冲洗仍阻2塞,治愈率63.0%。χ检验治疗组治愈率高于对照组(P〈0.05)。结论泪道探通联合球头硅胶管逆行植入治疗慢性泪囊炎具有操作简便、不切皮肤、不损伤组织结构等优点,临床疗效肯定。氟尿嘧啶对于预防泪道阻塞部位创面再次粘连,提高远期疗效有确切作用。

  • 简介:目的研究距角膜缘不同距离切口对非超声乳化小切口白内障人工晶体植入术后角膜散光及角膜内皮细胞变化的影响。方法对150例(150只眼)白内障患者按切口距角膜缘距离分为A、B和C三组。在角膜上方部位行直线形切口的非超声乳化小切口白内障人工晶体植入。分别于术前及术后1周、1个月、3个月用角膜地形图仪测量平均角膜散光度,用角膜内皮显微镜测量角膜内皮细胞计数。比较三组的平均角膜散光度和角膜内皮细胞平均密度及细胞平均丢失率。结果A、B、C组的平均角膜散光度在术后一周时分别是(2.29±0.84)、(1.90±0.77)、(1.79±0.85)D,其中A组与B组差异有统计学意义(P=0.008),B组与C组差异无统计学意义(P=0.0573),术后1月、术后3月各组差异无统计学意义(P〉0.05)。三组的角膜内皮细胞密度及角膜内皮细胞丢失率在术后差异无统计学意义(P〉0.05)。结论切口所处的位置距角膜屈光中心的距离越远,术后早期平均角膜散光度越小。白内障手术切口与术后角膜内皮细胞丢失无直接关系。非超声乳化小切口白内障人工晶体植入的最佳切口位置是角膜缘后2.0mm。
