Purpose:

To evaluate the effectiveness of pars plana vitrectomy in eyes with endophthalmitis from surgery and perforating eye trauma.

Materials Methods:

This study included 14 eyes of 14 patients (4 female, 10 male) with postoperative endophthalmitis (n=9) and traumatic endophthalmitis (n=5) that underwent pars plana vitrectomy, and intravitreal injection of vankomicine (1mg/0.1ml), ceftazidim (2.25mg/0.5ml), deksamethasone (0.1ml). Silicon oil in 11 eyes and balanced salt solution in 3 eyes were used as an internal tamponade at the end of pars plana vitrectomy. Vitreous samples were obtained and cultured from all eyes.

Results:

Mean follow-up was 9.8 ± 4.2 months. At baseline, visual acuity range of the patients was positive light perception (n=4) to hand movements (n=10). At final examination, visual acuity improved in 9 eyes and stayed same in 5 eyes. Vitreous culture was positive in 7 eyes. No intraoperative complication was seen during pars plana vitrectomy. Pars plana lensectomy in 3 eyes and phacoemulsification were conducted in an eye with postraumatic endophthalmitis. Retina was found attached in all eyes with silicon oil tamponade. Retinal detachment occurred in 2 of 3 eyes in which no silicon oil injected after pars plana vitrectomy. These 2 eyes underwent reoperation with silicon oil to reattach the retina.

Conclusion:

Retinal detachment was the commonest complication in eyes that underwent vitrectomy without silicone oil use. Earlier pars plana vitrectomy and silicone oil use favorably improved anatomic and functional success in eyes with endophthalmitis.
