Ocular trauma is associated with a high risk of proliferative vitreoretinopathy and poor postoperative visual outcomes, according to a study.

The study included 179 eyes with trauma and proliferative vitreoretinopathy (PVR). A control group comprised 221 eyes with trauma and no PVR.

Average follow-up was 11 months in the PVR group and 11.3 months in the control group, except for patients who had primary enucleation or evisceration. The average interval between injury and vitrectomy was 62.6 days in the PVR group and 16.8 days in the control group.

Interval of injury and vitrectomy longer than 28 days, severe vitreous hemorrhage and total retinal detachment were risk factors for PVR.

Presence of PVR, poor baseline visual acuity, relative afferent pupillary defect, total retinal detachment, and retinal tear or defect most strongly predicted poor anatomic and visual outcomes.

Forty-nine eyes (27.4%) in the PVR group and 115 eyes (52%) in the control group had anatomic restoration with ambulant visual acuity of 4/200 or greater.
