Abstract

PURPOSE:

To determine the frequency of peripheral iatrogenic retinal breaks in eyes undergoing small-gauge pars plana vitrectomy.

DESIGN:

Prospective, single-center, noncomparative interventional case series.

METHODS:

A consecutive series of patients that underwent 23- or 25-gauge vitrectomy between July 2010 and the end of October 2010 were included in the study. We excluded patients with retinal detachment, dislocated crystalline lens from complicated cataract surgery, endophthalmitis, and previous history of eye trauma or vitrectomy. We recorded prospectively the frequency of all retinal breaks noted during surgery of patients undergoing 23- or 25-gauge vitrectomy. The indications for vitreoretinal surgery were recorded, as were the location of retinal breaks, the presence or absence of an intact posterior hyaloid, status of lens, method of retinopexy, and use of a tamponade, together with the onset of a rhegmatogenous retinal detachment during the 3-month follow-up interval. Main outcome was rate of entry site breaks in small-gauge vitrectomy.

RESULTS:

We included 184 patients in this study. The mean age was 65.6 years (SD 13.2) and 46% were male. Retinal breaks occurred in 29 patients (15.7%) but breaks in only 6 (3.2%) were deemed to be related to the sclerotomies. Entry site breaks were not linked to the gauge of the instruments, but retinal breaks were more common in 23-gauge surgeries, although this was not statistically significant. One rhegmatogenous retinal detachment occurred in the postoperative period.

CONCLUSIONS:

Entry site retinal breaks are not common in small-gauge vitrectomy.
