A case-series study on coreoplasty in severe eye injuries

Objective To evaluate the application of coreoplasty in severe eye injuries. Investigate the role of coreoplasty in silicone oil eyes with iris defects in preventing the prolapse of silicon oil into the anterior chamber. Methods In this case-series study, severe eye injury cases with iris defects were selected from Eye Injury Vitrectomy Study (EIVS) database. The proportion of coreoplasty surgery was analyzed and the differences between the non-coreoplasty group and coreoplasty group in the incidence of silicon oil efflux into the anterior chamber were compared. Data were analyzed using χ2 test. Results Information of 1377 eyes in the EIVS database was explored, 245 cases (17.8%) showed traumatic iris defects and overall 76 eyes (31.0%) were undergone coreoplasty. In 128 silicon oil tamponated eyes with iris defects, the analysis revealed silicon oil efflux into the anterior chamber to be significantly more frequent in non-coreoplasty group (χ2=5.269, P=0.021). Conclusions In severe eye injuries with iris defects, the coreoplasty surgery should be more widely performed. In silicon oil eyes with iris defects, coreoplasty surgery could be advantage to minimize the risk of silicon oil efflux into the anterior chamber.
