PURPOSE:

To report surgical outcomes and both intraand postoperative complications in a large series of eyes undergoing 25-gauge pars plana vitrectomy (PPV).

METHODS:

A retrospective, single practice, interventional case series of 70 consecutive eyes that recently underwent 25-gauge PPV at Wills Eye Hospital using the latest Alcon Accurus system for a variety of indications including, but not limited to epiretinal membrane, vitreous hemorrhage, macular hole, and retinal detachment. Only primary, 3-port vitrectomies with a minimum postoperative follow-up of 12 weeks were included. Main outcome measures included Snellen visual acuity (VA), anatomical results, intraocular pressure (IOP), intraoperative complications, and postoperative complications.

RESULTS:

The mean follow-up was 22 weeks (range, 12 to 38 weeks). The overall visual acuity improved from 20/368 (range, 20/25 – hand motions) preoperatively to 20/105 (range, 20/20 – counting fingers) postoperatively (p<0.00005). All subgroups had statistically significant vision improvement. Intraoperative complications included retinal tears in 2 eyes (2.9%).
Postoperative complications included cataract progression in 17 eyes (42.5%), CME in 5 eyes (7.1%), and retinal detachment in 1 eye (1.4%). Postoperative day 1 IOP measurements were statistically lower than preoperative IOP measurements in fluid-filled eyes (p=0.031). There was no significant difference in preoperative and postoperative day 1 IOP measurements in eyes with intravitreal air (p=0.30) or gas (p=0.52). Sclerotomy sutures were required intraoperatively in five eyes (7.1%) and postoperative day 1 hypotony was noted in 4 eyes (5.7%). No postop interventions were required other than for the 1 eye with RRD.

CONCLUSION:

Surgical results were good and complications were rare in this series of 25-gauge PPV. Postoperative cataract progression and hypotony were the most common complications. Retinal tear or detachment was a rare complication in the intraoperative and postoperative setting. Fluid-filled eyes after 25-gauge PPV appear to have a higher risk of postop hypotony than air/gas-filled eyes.
