Intravitreal Injection of Triamcinolone Acetonide in Vitrectomy with Silicone Oil Placement

Purpose: To evaluate safety and efficacy of intravitreal triamcinolone acetonide (TA) injection at the end of pars plana vitrectomy with silicone oil tamponade. Methods: Eyes which underwent pars plana vitrectomy with silicone oil placement were enrolled. They were followed up for at least 6 months. GroupⅠ (twenty-three consecutive eyes) received an intravitreal injection of 4 mg TA at the end of the surgery, whereas GroupⅡ (twenty-six eyes) did not. Results: Postoperative vision improved by 2 lines or more in 9 eyes (39.1%) of GroupⅠ and 9 eyes (34.6%) of GroupⅡ. The posterior pole was attached in all of GroupⅠ(100.0%) and twenty-four eyes (92.3%) of GroupⅡ (P=0.17). The postoperative BCVA was 5/200 or better in fifteen eyes (65.2%) of GroupⅠand fourteen eyes (53.8%) of GroupⅡ (P=0.51). Eight eyes (34.8%) in GroupⅠ and six eyes (23.1%) in GroupⅡ had an intraocular pressure higher than 21 mmHg (P=0.36). All of them were controlled with medications. Two eyes in GroupⅡ required an additional operation due to recurrence of tractional retinal detachment from the fibrous membrane. Visually significant ocular complications related with TA injections were not noted. Conclusions: The intravitreal injection of TA into silicone-filled vitrectomized eyes seems safe and efficient. But, a prospective study is necessary to demonstrate the long-term safety and efficacy.
