目的 :探讨消除白内障囊外摘除加人工晶体植入术后患者术眼、额部胀痛等不适的方法。方法 :将施行白内障囊外摘除加人工晶体植入术 82例、90眼随机分为治疗组 4 6眼、空白对照组 4 4眼 ,治疗组术后4h静脉输入 2 0 %甘露醇 2 5 0ml,2组均在术后 2 4h测眼内压。结果 :术后 2 4h甘露醇治疗组眼内压平均升高4 .2± 2 .1mmHg ,空白对照组平均升高 12 .9± 2 .7mmHg ,差异有显著性 (P <0 .0 5 )。术后 2 4h平均眼内压甘露醇治疗组为 19.4± 2 .2mmHg ,均未高于 2 5mmHg ,空白对照组为 2 8.1± 2 .9mmHg ,2 4眼 (5 5 % )眼内压高于30mmHg。结论 :在可能出现术后高眼压之前 ,静脉输入甘露醇 ,可避免因残留透明质酸钠致高眼压的发生
OBJECTIVE: To explore the method to eliminate the discomfort of eyes and forehead in patients after extracapsular cataract extraction and intraocular lens implantation. Methods: 82 cases of extracapsular cataract extraction combined with intraocular lens implantation were performed. 90 eyes were randomly divided into treatment group (46 eyes) and control group (44 eyes). In the treatment group, 20% mannitol , 2 groups were measured intraocular pressure 24 h after surgery. Results: The intraocular pressure of mannitol group increased by 4.2 ± 2.1mmHg on average 24 h after operation, while the average value of blank control group increased by 12.9 ± 2.7mmHg (P <0.05) . The mean intraocular pressure of mannitol group at 24 hours after operation was 19.4 ± 2.2mmHg, both of which were not higher than 2 5mmHg, the control group was 2 8.1 ± 2.9mmHg, the intraocular pressure of 24 eyes (55%) was higher than 30mmHg. Conclusions: Mannitol intravenously before ophthalmoplegia may occur, which can prevent the occurrence of intraocular hypertension caused by residual sodium hyaluronate
