Triamcinolone after pars plana vitrectomy for diabetic hemorrhage reduces rebleeding, reoperation
Retina. 2008;28(9):1241-1246.
Intravitreal injection of triamcinolone acetonide at the end of pars plana vitrectomy for diabetic vitreous hemorrhage may help prevent early rebleeding and reoperation.
After surgery, 38 patients receiving a 4-mg injection of triamcinolone had significantly greater visual acuity at 6 months (0.63 ± 0.23 logMAR) when compared with 34 postoperative patients who did not receive the injection (0.87 ± 0.24 logMAR; P < .001).
At day 1 and week 1 after surgery, mean IOP was higher in the triamcinolone group compared with control eyes, but IOP did not differ at 1, 3 or 6 months postoperatively. There was cataract progression in both groups, but there was no difference in the rate of progression when patients who were not dosed at the end of surgery were compared with patients who were dosed.
However, the researchers noted, patients who received triamcinolone during surgery had a higher risk of posterior capsular progression compared with patients who did not receive an injection (P = .011).
