To evaluate the effects of treatment of severe ocular injury with NLP by 23-gauge vitreoretinal surgery, and to analyze the relevant factors.


Twenty-one eyes of 21 patients with severe ocular injuries were involved in this study. All injured eyes with large ruptures with lens dislocation and vitreous loss together with choroidal and retinal detachment, vitreous hemorrhage, suprachoroidal hemorrhage and blood-stained cornea received the combined vitrectomy. The surgical procedures mainly included membrane peeling, retinotomy or retinectomy at the incarceration sites, subretinal surgery, intraoperative use of perfluorocarbon liquids, laser treatment, and silicone oil filling.


Patients with no light perception received vision of better than light perception postoperatively was 30%, and the visual acuity ranged from LP to 0.3 postoperatively. The retina attachment was achieved in 80% of all injured eyes. The mainly postoperative complication was fibrosis exudates in the anterior chamber in all eyes, and retinal redetachment ocurred in 4 eyes.


Combined 23-gauge vitrectomy is a safe and effective method in treating severe ocular injury with NLP. However, the visual prognosis is limited because of primary and secondary tissue destruction. In cases of severe ocular injury, ocular salvage, not only vision, may be the most realistic goal. The reasons for NLP before the surgery should be correctly analyzed. A permanent silicone oil tamponade should be carefully considered in patients in whom the operated eye is the only functional eye.
