简介：目的：分析《标准对数视力表》与《低视力视力表》对远用视力检查的临床意义及临床价值。方法：随机抽取本院验光部验光患者59例（118眼）,每位患者分别进行两种视力表的远用视力检查,然后记录裸眼视力以及矫正视力检查结果,再进行配对设计资料检验。结果：裸眼视力检查t=2.9944,矫正视力检查t=3.5564,P〈0.05,两种视力表无论是裸眼视力还是矫正视力在统计学上均有显著性差异。结论：两种视力表的视力检查结果有所差异,裸眼视力相差19.953′视角,矫正视力相差15.849′视角,且低视力专用视力表的均值均小于标准对数视力表。

简介：目的制备左氧氟沙星热敏型耳用凝胶，并对其体外释放性能进行检测。方法制备以泊洛沙姆407为基质的左氧氟沙星热敏性耳用凝胶，根据中耳温度筛选泊洛沙姆407的最佳处方浓度，采用立式Franz扩散池模型对该制剂的体外释放性能进行研究。结果左氧氟沙星检测浓度的线性范围为3．0～10．5mg／L，在此浓度范围内吸光度（A）和浓度（c）呈良好的线性关系，即C（mg／L）=12．582A＋0．2976（r=0．9986，n=6）；平均回收率为100．09％，相对标准偏差（RSD）=0．61％（n=6）；泊洛沙姆407在处方中的最佳浓度为17％；药物释放具有一定的控释性，释放符合零级动力学特征。结论该耳用热敏型凝胶具有较好的控释性能，且制备方法简单，用药剂量易于控制。

简介：目的：探讨儿童瞬目症BUT情况，为临床治疗提供依据。方法：215例患者均排除全身疾患，检查角膜、结膜、屈光不正等，着重检查BUT，详细了解患者病史，不良生活习惯等，治疗上停用含有防腐剂及激素类滴眼液，避免及纠正不良卫生及生活习惯，心理治疗，合理用眼，矫正屈光不正，给予不含防腐剂的滴眼液点眼，如3g／L艾丽滴眼液3次／d点眼，需用抗生素的给予可乐必妥滴眼液3～4次／d点眼，酌情给予抗病毒及维生素类药物。结果：215例患者BUT小于10s者197例（91．6％）326眼，其中5S以下123例224眼。本组215例病例中经过7～28d治疗，173例（80．5％）治愈，37例（17．2％）好转，5例（2．3％）无效，均未患眼部疾病，且不配合治疗，仍每天看电视或玩电脑游戏2h以上。经治疗BUT正常者192例（89．3％），好转19例（8．8％）无效者4例（1．9％）。随访1～6mo，复发31例，均为长期看电视、玩电脑、习惯揉眼者，BUT检查再次异常者，重复治疗后治愈或好转。结论：泪膜的保持并发挥其生理功能与瞬目动作休息相关，我们认为泪膜稳定性差是瞬目症的另一重要因素，BUT检查在诊治儿童瞬目症中起着关键的作用，它可以正确指导医生合理用药，使患者早日康复，而且简单易行，无痛苦，儿童易接受。我们建议BUT可作为儿童瞬目症的常规检查。
