The Result of Consecutive Vitrectomy in Penetrating Ocular Injury

ABSTRACT

We studied retrospectively the results of consecutive vitrectomy following traumatic ruptured globe repair in 31 patients, who had been followed six months or longer postoperatively. Twenty-seven patients (87%) were male and 21 (68%) were between the second and fourth decades. Functional success was achieved in 13 patients(42%) and anatomic success in 14 patients(45%). Nine patients vitrectomized within two weeks after primary repair had 100% success rate, and seven patients operated between two weeks and one month had 96% success rate, but 15 patients vitrectomized after one month had 80% success rate. Five among eight eyes which underwent other operations prior to vitrectomy showed success, in contrast to 96% (22 eyes) success among 23 eyes which underwent planned vitrectomy without any other intervening surgical procedure. Better previtrectomy conditions including simple vitreoretinal incarceration or proliferative vitreoretinopathy of Grade B or milder achieved success in 96%, but poor conditions including prephthisical status and proliferative vitreoretinopathy of Grade C or more severe in 67% In conclusion, the overall success rate of consecutive vitrectomy in repaired ruptured globe was 87%. Prephthisical condition and severe proliferative vitreoretinopathy showed poor prognosis. We emphasize the necessity of well-planned vitreous surgery and the importance of its adequate timing in the management of penetrating injury.
