Vitreoretinal surgery for shotgun eye injuries: outcomes and complications

PURPOSE

To analyse the postoperative anatomic and functional outcomes in addition to complications after vitreoretinal surgery for patients with shotgun eye injuries related to hunting accidents.

MATERIALS

Retrospective review of the clinical records of all cases of shotgun eye injuries presented between January 2000 and January 2011 and with a minimum follow-up of 1 year. Collection of demographics, type of injury, choice of management, complications and final surgical success with final visual acuity is reported.

RESULTS

Twenty eyes of 19 patients (all male) with a mean age of 36.1 years (range 16-60 years) were included in the study. Mean postoperative follow-up was 47.5 months (range 15-118 months). Best corrected visual acuity (BCVA) at presentation ranged from perception of light to 20/200. Ten eyes had a penetrating injury and 10 others had a perforating injury. All the eyes underwent an initial vitrectomy and the intraocular pellet was removed in all the 10 penetrating injuries. Concurrent cataract surgery was performed in 12 cases, internal tamponade was used in 15 cases and a supplemental encircling scleral buckle was inserted in 12 cases. One additional vitreoretinal surgery was required in seven cases (35%) and two additional surgeries required in two other cases (10%). At last follow-up BCVA ranged from NPL to 20/20 and was 20/100 or better in 10 eyes (50%). All patients had a flat retina except for two cases (10%) that developed severe proliferative vitreoretinopathy.

CONCLUSION

These results suggest that vitreoretinal surgery can offer good visual rehabilitation in patients with shotgun eye injuries.
