Analysis of intravitreal injection of triamcinolone acetonide before vitrectomy for retinal detachment associated with choroidal detachment / 国际眼科杂志(Guoji Yanke Zazhi)

ABSTRACT

AIM: To observe the clinical effects of intravitreal injection of triamcinolone acetonide ( TA ) before vitrectomy for retinal detachment associated with choroidal detachment. · METHODS: Totally 23 cases ( 23 eyes ) of retinal detachment associated with choroidal detachment in our hospital were treated by intravitreal injection of TA 4-5d before 23-Gauge micro-invasive vitrectomy combined with silicone oil injection. All the cases were followed up between 6 to 9mo. The anatomic retinal reattachment, visual acuity, intraocular pressure and postoperative complications were observed and analyzed. ·RESULTS: After the surgery, the visual acuity of all patients were improved, with 9 eyes better than 0. 3 (39%), and 18 eyes better than 0. 05 (78%). The BCVA at 1wk, 1 and 3mo and last follow up were different compared with before operations (P<0. 05). The mean intraocular pressure was 4. 02±1. 47mmHg before injection, 13.69±4. 68mmHg before operation (P<0. 05), and17.72±5.87 mmHg after operation (P<0.05). The retina of all patients treated were reattached 2wk post-operatively. The retinal reattachment rate after the primary surgery and the secondary surgery was 87% and 100%, respectively. Post-operative complications included 7 eyes of transient high intraocular pressure, occurred during 12-14d after operations and returned to normal after less glucocorticoid eye drops and giving IOP lowering drugs. There were no intraocular hemorrhage, iatrogenic retinal breaks, infections, or lens injuries. · CONCLUSION: Intravitreal injection of TA before vitrectomy for retinal detachment associated with choroidal could improve the clinical effects, and decrease the difficulty of surgery while the injection itself is pretty safe.
