Abstract:
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 IOP 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 pupillary dilator.
