Abstract
AIM: To explore the effects of sodium hyalurantae in complex trabeculectomy.
METHODS: Casecontrol studies. 56 eyes with primary glaucoma who need complex trabeculectomy were randomly divided into observation group and control group with 28 eyes in each group. Patients in the observation group were applied the sodium hyalurantae, and the control group were not applied during the operation. The changes in anterior chamber, bleb, IOP and corneal endothelial cells in two groups were observed.
RESULTS: The anterior chambers of 28 eyes in observation group formed early postoperatively. The shapes of filter blebs in observation group were better than control group at three months after operation. Functional filtering bleb appeared in 27 eyes(96%) in observation group and functional filtering bleb appeared in 26 eyes (93%) in control group. IOP of observation group is slightly higher than that of control group early postoperatively, and three months after operation, IOP of observation group was somewhat lower than that of control group. There was no statistical difference between the corneal endothelial cells of preoperation and postoperation in two groups.
CONCLUSION: It can make the anterior chamber form better by using sodium hyalurantae in complex trabeculectomy, and it can support filtration path to inhibit scar formation and increase the successful rate of complex trabeculectomy.

随着显微眼科手术的发展,黏弹剂在眼科的应用越来越广泛。我们在青光眼复合小梁切除术中使用黏弹剂,观察两组患者术后前房、滤过泡、眼压、角膜内皮的变化并作对比。资料报告如下。
1对象和方法
1.1对象
收取200909/200910在我院住院的原发性青光眼患者56眼,年龄42~78岁,男24眼,女32眼,其中原发性开角型青光眼18眼,慢性闭角型青光眼进展期及晚期16眼,急性闭角型青光眼22眼。56眼中有5眼因术前药物无法控制眼压而在高眼压状态下手术降眼压。以上病例均符合复合小梁切除术的适应证。56眼患者按随机数字法分为观察组和对照组,每组28眼,观察组术中均使用黏弹剂,对照组术中不使用黏弹剂。5眼术前药物无法控制眼压者有2眼在术中使用了黏弹剂归于观察组,3眼未在术中使用黏弹剂而归为对照组。观察两组患者术后前房、滤过泡、眼压、角膜内皮的变化并作对比。
1.2方法
所有56眼常规行复合小梁切除术,均由同一医师完成。术中根据具体情况在结膜瓣和巩膜瓣下放置不同浓度及时间的丝裂霉素棉片,其中有6眼术中未使用丝裂霉素。术中常规使用可调节缝线,并在透明角膜缘9∶00位作辅助切口,术中使用黏弹剂者分别于切小梁前及巩膜瓣缝合BSS恢复前房稳定后从辅助切口注入适量黏弹剂入前房,使手术完毕时眼压为指测T~T+1,对照组除术中未使用黏弹剂外,余步骤均相同。所有手术眼常规术前角膜内皮镜检查并于术后3mo复查。
2结果
2.1术后早期前房形成情况
术后前房形成情况按照Spaeth法分类,浅Ⅰ:周边虹膜与角膜部分接触,浅Ⅱ:周边虹膜与角膜接触,但瞳孔区角膜内皮与晶状体前囊之间仍有前房,浅Ⅲ:无前房。术后观察组28眼前房均形成良好,无浅前房的发生,对照组2眼术后第2d前房浅Ⅰ,常规扩瞳抗炎处理后术后第5d前房深度与对侧眼相当,此2眼均为高眼压状态下手术者。
2.2两组术后滤过泡情况对比
两组患者术后早期均获得弥散隆起的功能性滤过泡,术后3mo观察组的滤过泡更为弥散隆起,功能型滤过泡27眼(96%),对照组滤过泡相对扁平,功能型滤过泡26眼(93%)。观察组中有1眼术后1~3mo期间出现滤过泡包裹化,经处理转为功能型滤过泡;有1眼滤过泡扁平瘢痕化,需局部点药控制眼压;对照组术后1~3mo期间有2眼出现滤过泡包裹化,1眼经处理转为功能型滤过泡,另1眼仍然表现为瘢痕化;有1眼滤过泡扁平瘢痕化,需局部点药控制眼压。
2.3两组术后1wk内眼压的比较及术后3mo眼压的比较
两组术后1wk内眼压的比较及术后3mo眼压的比较见表1。术后早期观察组眼压稍高于对照组,随着前房内黏弹剂的排出,术后1wk左右两组的眼压值比较接近,术后3mo眼压的均值观察组更平稳一些。表1 两组术后1wk内及术后3mo眼压的比较表2 两组术前、后角膜内皮细胞情况对比
2.4两组术前术后角膜内皮细胞情况对比
两组术前、后角膜内皮细胞情况对比(表2)。观察组2眼,对照组3眼术前药物无法控制眼压而在高眼压状态下手术降眼压者,术前因角膜水肿未测量出角膜内皮细胞情况,此5眼结果未纳入本次观察。从表2的数据结果可得出结论:两组患者术前及术后的角膜内皮细胞数目及正常形态角膜内皮细胞的比例无统计学意义。
从上述结果可以得出结论,观察组术后早期能较好的形成前房;两组术前、术后角膜内皮细胞情况无统计学差异。术后3mo观察组的滤过泡更为弥散隆起,功能型滤过泡(96%),对照组滤过泡相对扁平,功能型滤过泡(93%);术后早期观察组眼压较对照组稍偏高,术后3mo观察组眼压较对照组更低一些;在复合小梁切除术中使用黏弹剂可使术后早期前房更稳定,并能支撑滤过道顺利度过早期的瘢痕化期,从而使术后的眼压能控制在相对更为安全的范围。
