摘要
目的分析强化散瞳对玻璃体视网膜手术后早期高眼压的作用效果。设计回顾性病例系列。研究对象因各种原因行玻璃体视网膜手术、并且术后第1天眼压≥30 mmHg的患者32例(34眼)。方法对上述患者使用复方托吡卡胺滴眼液连续点手术眼3次,每次间隔5分钟,用药2小时后复测眼压,并对眼压等参数行t检验,比较用药前后眼压的变化。主要指标用药前、后眼压。结果用药前患者平均眼压(37.26±6.07)mmHg,用药2小时后平均眼压(34.82±8.46)mmHg,平均眼压下降2.44mmHg,差异具有统计学意义(P=0.02)。其中20例(58.82%)眼压下降,平均眼压下降6.2 mmHg;4例(11.76%)眼压不变;10例(29.41%)眼压升高,平均眼压升高4.1 mmHg。结论玻璃体视网膜手术后眼压升高并不是停止使用散瞳剂的理由,合理使用可以使近60%的患者眼压下降。
Objective To analyze the effect of intensive pupillary dilation on intraocular pressure （IOP） in early stage after vitreoretinal surgery （VRS）. Design Retrospective case series. Participants 32 patients （34 eyes） with 30 mmHg or more of IOP at the first day after VRS were enrolled in this study. Methods Tropicamide-phenylephrine eyedrop （Mydrin-P ） was applied to the operated eye 3 times with interval of 5 minutes and IOP was measured again 2 hours later. IOPs were compared with t test. Main Outcome Measures IOP. Results The mean IOP was 37.26±6.07 mmHg before using tropicamide-phenylephrine eyedrop and 34.82±8.46 mmHg after using it two hours later （P=0.02）, and mean decline of IOP was 2.44 mmHg in general. IOP was decreased in 20/34 eyes （58.82%） with mean decline 6.2 mmHg. IOP was unchanged in 4/34 eyes （11.76%）. IOP was increased in 10/34 eyes （29.41%） with mean lOP up 4.1 mmHg. Conclusions The IOP increasing after vitreoretinal surgery is not the reason for stopping pupillary dilator. On the contrary, the IOP of about 60% patients can decrease with rational using pupillarv dilator.
