To compare the efficacy of two preoperative steroid regimens for cataract surgery in patients with uveitis.
40 uveitis patients with cataract underwent phacoemulsification and intraocular lens (IOL) implantation. Preoperatively they were randomised into two groups: group 1 (20 patients) received a single dose of intravenous methylprednisolone (15 mg/kg) half an hour before surgery, and group 2 (20 patients) received a 2 week course of oral prednisolone (0.5 mg/kg) which was tapered postoperatively. Preoperatively patients had aqueous flare and cells measured with the Kowa laser flare meter. On days 1, 7, 28, and 90 aqueous flare and cells were measured, and on days 7 and 90 fluorescein angiography was performed to determine the incidence of cystoid macular oedema (CMO).
At all postoperative visits the mean increase in flare was greater for group 1 (intravenous steroid). Patients with posterior synechiae had greater blood-aqueous barrier damage (BAB) postoperatively. There were no statistically significant differences in logMAR visual acuity and incidences of CMO between the two groups at 7 and 90 days.
A 2 week course of oral prednisolone, tapered postoperatively, produced a better recovery of the BAB than a single dose of intravenous methylprednisolone and is thus the recommended preoperative regimen.
比较两种术前类固醇治疗方案对葡萄膜炎患者白内障手术的疗效。
40例患有白内障的葡萄膜炎患者接受了超声乳化白内障吸除术和人工晶状体(IOL)植入术。术前,他们被随机分为两组:第1组(20例患者)在手术前半小时接受单剂量静脉注射甲泼尼龙(15mg/kg),第2组(20例患者)接受为期2周的口服泼尼松龙(0.5mg/kg)治疗,并在术后逐渐减量。术前使用科瓦激光光斑分析仪测量患者的房水闪光和细胞。在第1、7、28和90天测量房水闪光和细胞,并在第7天和第90天进行荧光素血管造影以确定黄斑囊样水肿(CMO)的发生率。
在所有术后随访中,第1组(静脉注射类固醇)的闪光平均增加幅度更大。有虹膜后粘连的患者术后血-房水屏障损伤(BAB)更大。两组在第7天和第90天的logMAR视力和CMO发生率无统计学显著差异。
术后逐渐减量的为期2周的口服泼尼松龙治疗方案比单剂量静脉注射甲泼尼龙能使BAB更好地恢复,因此是推荐的术前治疗方案。
