目的:报告深度前角膜成形术(DALK)后眼压升高的发病率和危险因素。设计:回顾性病例研究。方法:一项回顾性研究,调查了三级中心2004至2008年间5年DALK后IOP升高的病例。少于6个月随访的患者被排除在外。眼压升高定义为IOP21 mmHg。结果:眼压升高发生率36.1%(44/122例),11.4%(n=5)发生在一周之内。眼压升高平均持续48.9天(SD65.5)。导致瞳孔与空气隔离,肿胀移植和皮质类固醇反应。有3例需要外科干预降低眼压(6.8%)。在多变量分析中,DALK前使用0.1%奥洛他定或者环孢菌素滴眼液(OR=14.41,95%CI=1.43-147.23)和DALK后使用1%外用泼尼松龙醋酸盐或者1%地塞米松,DALK后IOP升高发生率更高(OR=4.79,95%CI=0.73-31.52)。DALK后5年时,71例患者里有3人(4.48%)发展成新生青光眼缺陷,1名以前就有青光眼的患者青光眼缺陷发生了进展。结论:我们的研究认为DALK与术后一过性眼压升高显著相关,而与5年新生青光眼关联不显著。 DALK后IOP升高的风险因素包括使用1%外用泼尼松龙醋酸盐或者0.1%地塞米松,以及DALK前使用0.1%奥洛他定或者任何浓度的环孢菌素滴眼液。

Purpose:To report the incidence and risk factors of elevated IOP following deep anterior lamellar keratoplasty (DALK).

Design:A retrospective case series.

Methods:A retrospective study investigating the 5-year incidence of raised IOP following DALK cases performed from 2004 to 2008 in a tertiary center. Patients with less than 6months of follow-up were excluded. Elevated IOP was defined as IOP >21mm Hg.

Results:An episode of elevated IOP occurred in 36.1% of cases (44/122 cases), 11.4% (n= 5) occurring within the first week. The average duration of raised IOP was 48.9 (SD: 65.5) days. Causes included pupil block from air, swollen grafts, and corticosteroid response. Surgical intervention to lower IOP was required in 3 cases (6.8%). In multivariate analyses, the use of Olopatadine 0.1% or cyclosporine eye drops before DALK (OR=14.51, 95% CI= 1.43–147.23) and use of topical prednisolone acetate 1% compared with dexamethasone 0.1% post DALK (OR= 4.79, 95% CI=0.73–31.52) were associated with higher rates of elevated IOP post DALK. At 5 years post DALK, 3 of 71 cases (4.48%) developed de novo glaucomatous field defects, and 1 case with pre-existing glaucoma had progression of glaucomatous field defect.

Conclusions:DALK was associated with a significant incidence of transiently elevated IOP postoperatively, but had a low incidence of de novo glaucoma at 5 years in our study. Risk factors for raised IOP post DALK included the use of topical prednisolone acetate 1% compared with dexamethasone 0.1%, and the use of Olopatadine 0.1% or any concentration of cyclosporine eye drops prior to DALK.
