囊袋张力环在马凡综合征晶状体半脱位手术中的应用

目的探讨囊袋张力环在马凡综合征晶状体半脱位手术治疗中的应用效果。方法对32例(54眼)马凡综合征伴晶状体半脱位患者在晶状体摘出联合人工晶状体植入术中,将囊袋张力环植入晶状体囊袋后再植入后房型人工晶状体。术后定期随访,观察术后患者视力、疗效和并发症等。结果 32例54眼患者均手术成功,术后患者视力均有不同程度的提高;术后3个月最佳矫正视力>0.6者15眼,0.3～0.6者36眼,<0.3者3眼。随访期间未发现人工晶状体脱位、眼压升高及玻璃体脱出等并发症发生。结论囊袋张力环应用于马凡综合征晶状体半脱位摘出手术可以提高手术安全性,防止人工晶状体偏位,避免或减少玻璃体脱出,是马凡综合征伴晶状体半脱位患者行超声乳化白内障手术的有效辅助手段。

术后抗炎汤对白内障晶体植入术患者白细胞介素2及其受体的影响

[目的]探讨具有补益肝肾、益气活血、祛风清热作用的术后抗炎汤(主要由黄芪、当归、枸杞、生地、防风、白 术、桑叶、菊花、钧藤等中药组成)对白内障患者手术后血清与泪液白介素2(IL-2)和可溶性白介素2受体(SIL-2R)的 影响及其临床意义。[方法]将47例行超声乳化加人工晶体植入术的白内障患者随机分为对照组(26例)和中药组(21 例),对照组给予常规手术和滴眼液,中药组在对照组的药物治疗基础上加用术后抗炎汤。另选15例门诊体检的健康老年 人为正常组。检测白内障患者手术前后血清和泪液IL-2和SIL-2R水平的变化。[结果]对照组和中药组术后血清SIL-2R均 比术前升高(均P<0.01),而中药组术后泪液SIL-2R与术前相比差异无统计学意义(P>0.05),对照组术后血清和泪液 IL-2和SIL-2R水平高于中药组和正常组(P<0.05或P<0.01)。[结论]术后抗炎汤通过调节眼局部免疫功能,能有效减 轻白内障术后的炎症反应。     

环戊硫酮治疗干眼的临床疗效评价

Objective To investigate anethol trithione therapic efficiency on dry eye. Methods It was a prospective random double-blind controlled study. Eighty cases diagnosed dry eye in Ocular Surface Out-patient Clinic of Xiamen University Affiliated Xiamen Eye Center from 2006 to 2008 were divided into two groups: anethol trithione group and control group, 40 cases in each group. Every group was then divided into two subgroups: weak dry eye subgroup, middle and severe dry eye subgroup. All groups had been added with 0.05% refresh drops. All patients had been detected and evaluated by subjective symptoms of dry eye, visual acuity,corneal fluorescent staining(F1), break-up time(BUT) and Schirmer Ⅰ test (SⅠT) at pre-therapy and 3,7,28 d of post-therapy. All groups had been compared and analyzed by F test and sample mean difference (SMD) or median difference (MD) comparison between pre-therapy and post-therapy. Results Except of tear and red eye, the other subjective symptoms of dry eye, F1, BUT and SⅠT of weak dry eye subgroup of both groups had been improved at 7 d after therapy. Only those of middle and severe dry eye subgroup of anethol trithione group had been improved at 7 d after therapy compared with those of pre-therapy: SMD=0.96 (visual tiredness), 1.26 (dry and unsmooth sensation), 0.82 (foreign body sensation), 1.28 (burning sensation), 1.05 (photophobia), 1.48 ( pain ) ; MD=0.30 (visual acuity), 4.00 (F1) ,5.00 (BUT), 5.00 (SⅠT) [F=15.30 (visual tiredness), 15.68 (dry and unsmooth sensation ), 13.56 (foreign body sensation), 20. 91 ( burning sensation ), 18.90 (photophobia), 27.22 ( pain ), 10.54 (visual acuity), 188.21 (F1) ,261.76 (BUT) ,269.05 (SⅠT) ;P<0. 05]. Those of middle and severe dry eye subgroup of control group hadn't significantly been improved at 28 d after therapy: SMD=0.10 (visual tiredness) ,0.16 (dry and unsmooth sensation) ,0.09 (foreign body sensation) ,0.38 ( burning sensation ), 0.24(photophobia) ,0.36 (pain) ,0.23 (red eye) ; MD=0.10 (visual acuity) ,0.50(F1) ,0.50(BUT), 0.50(SⅠT) [F=1.76 (visual tiredness), 1.61 (dry and unsmooth sensation), 1.02 (foreign body sensation),2.39 (burning sensation), 2.42 (photophobia), 2.73 ( pain ), 2.55 ( red eye ), 1.46 ( visual acuity) ,2.35 (F1) ,2.90 (BUT) ,2.76 (SⅠT) ; P>0.05]. SⅠT of anethol trithione group had been improved more significantly after therapy (F=13.77, P<0.05). Conclusion Anethol trithione could significantly improve middle and severe dry eye patients' symptoms and signs whose lacrimal gland function survival and it has clinical application value.
