简介:目的:探讨玻璃棒法按摩睑板腺与常规疗法联合治疗睑板腺功能障碍(MGD)的临床疗效。方法:回顾性分析2016-08/2017-06我院收治的MGD患者130例220眼,根据治疗方式不同进行分组,其中给予常规治疗即1g/L氟米龙滴眼液联合自行热敷的患者设为对照组(65例112眼),给予圆头玻璃棒按摩睑板腺联合常规疗法的患者设为联合组(65例108眼)。比较两组患者治疗前后眼表疾病指数量表(OSDI)评分、泪膜破裂时间(BUT)、基础泪液分泌试验(S|t)、角膜荧光素染色(CFS)评分、睑缘评分、睑板腺分泌物性状评分和眼压情况及临床治疗有效率。结果:治疗前,两组患者OSDI评分、BUT、S|t、CFS评分、睑缘评分、睑板腺分泌物性状评分、眼压情况差异均无统计学意义(P>0.05)。治疗2wk后,联合组患者OSDI、CFS、睑缘及睑板腺分泌物性状评分均低于对照组,BUT和S|t均大于对照组,差异均有统计学意义(P<0.01);两组患者眼压均有所升高,但均≤21mmHg,两组间差异无统计学意义(P>0.05)。治疗2wk后,联合组总有效率为92.6%(100/108),对照组总有效率为78.6%(88/112),差异具有统计学意义(P<0.05)结论:玻璃棒法按摩睑板腺与常规疗法联合治疗MGD能够有效改善眼表症状和睑板腺分泌功能,促进泪液分泌,提高临床治疗有效率。
简介:目的:分析不同年龄段干眼症患者睑板腺情况。方法:选取2015-11/2016-04就诊于我院的干眼症患者301例598眼,按年龄分为8组,分别为A~H组。应用眼表综合分析仪检查各组干眼症患者睑板腺腺体缺失情况、腺体形态变化、睑板腺开口阻塞及睑酯情况,分析比较各组之间的睑板腺变化规律。结果:所有患者均有不同程度睑板腺腺体缺失,各组之间腺体缺失面积比较,差异有统计学意义(χ~2=336,P〈0.05)。A组腺体数目无减少,B~H各组之间腺体数目减少比较,差异有统计学意义(F=36.4357,P〈0.05)。腺体形态从40岁开始逐渐变细,其与年龄呈反相关。睑板腺开口阻塞情况及睑酯的性状,各组之间无明显差异。结论:眼表综合分析仪能客观精准地检查出干眼症患者的睑板腺情况,提供不同年龄段干眼症患者睑板腺变化规律的量化结果,为干眼症的病因诊断提供判断依据,指导临床治疗。
简介:目的:对比全身麻醉与局部麻醉下进行儿童霰粒肿切除术的综合疗效。方法:回顾性病例对照研究。将2015-01/2016-12在我院接受霰粒肿切除手术的双眼霰粒肿患儿(4~10周岁),根据采用的麻醉方法分为两组:全身麻醉组(全麻组,67例134眼)和局部麻醉组(局麻组,72例144眼)。分析两组患者的疼痛及术后心理创伤,以及术后1mo眼表健康状况、术后1a内复发率和并发症等四个方面的差异。结果:全麻组和局麻组患儿均未出现麻醉相关并发症和意外。全麻组患儿术中不存在疼痛,术后3h的面部表情疼痛量表(FPS-R)值为4.94±1.23分,低于局麻组(7.00±1.14分),差异有统计学意义(P<0.001)。全麻组患儿有12例出现再次就医回避,局麻组为35例,差异有统计学意义(P<0.01)。全麻组的泪膜破裂时间、泪膜脂质层厚度和泪河高度均高于局麻组,差异有统计学意义(P<0.001);其睑脂性状评分也低于局麻组,差异有统计学意义(P<0.01)。全麻组患儿囊肿复发率为6.0%,低于局麻组的20.8%,差异有统计学意义(P<0.05)。全麻组患儿出现并发症发生率为4.5%,局麻组为15.3%,差异有统计学意义(P<0.05)。结论:全身麻醉下进行儿童霰粒肿手术具有术后疼痛轻、患儿依从性好的基本优点。与局部麻醉下手术相比,全身麻醉术中能够进行精细操作,术后眼表健康情况更好,并发症更少。
