Risk factors analysis of recurrence retinal detachment with silicone oil (SO) tamponade

Abstract

Objective To find out risk factors of recurrence retinal detachment (RD) with silicone oil (SO) tamponade by analyze their clinical feature.Methods A retrospective study of 578 patients (578 eyes) who underwent vitrectomy and SO tamponade for complex retinal detachment between January 2008 and December 2013.Their clinical feature was analyzed in stratification,odds ratio was calculated and risk factors were found.Results PVRD,high myopia,inferior retina holes and macular holes combined high myopia were the main risk factor for recurrence RD with SO tamponade.Their OR and 95％CI were 4.126(2.481,6.862),1.841(1.125,3.011),11.141(5.094,24.359),7.181(2.794,18.454) respectively.The size and quantity of breaks,moderate myopia and different surgeon had no effect on recurrence of RD (P ＞0.05).Recurrent patients,who with unclosed breaks or new breaks was 82.67％ of total recurrence (75 patients),who with more than PVRC and unclosed breaks was 42.67％,and who with only PVR without breaks was 17.33％.Conclusions Recurrent ratio of patients who underwent vitrectomy and SO tamponade in the first time will increase if one of the following factors is involved,including PVRD,high myopia,inferior retina holes and macular hole combined high myopia.Unclose breaks or new breaks may play a key role in the recurrence of RD.
