Abstract
Intravitreal silicone oil injection is useful to manage the complicated retinal detachment. However, many comlications including secondary glaucoma can occur followin gsilicone oil injection. We performed this study to investigate the incidence and risk factors of silicone oil induced secondary glaucoma. The medica records of 213 eyes of 210 consecutive patients who underwent pars plana vitrectomy and silicone oil injection between January 1990 and June 1997, were reviewed retrospectivel. Fifty five of 213 eyes(25.8%) developed secondary glaucoma. The mean follow-up period was 33.4 months. The mean amount of injected silicone oil was 5.0+/-1.0ml, and 33.4 the mean numbers of operation prior to the silicone oil injection was 2.3. 65.5% of secondary glaucoma was developed within 1 year of silicone oil injection. High preoperative intraocular pressure(IOP) (p=0.004), high myopia(p=0.015) and presence of silicone oil in anterior chamber(p=0.004) increased the incidence of secondary glaucoma significantly. In conclusion, patients who have high preoperative IOP, high myopia and silicone oil in anterior chamber must be carefully followed after silicone oil injection due to high incidence of secondary glaucoma, especially during the first 1 year.
