surgical outcomes after vitrectomy in severely traumatized eyes with no light perception and flat erg

Purpose: To report visual outcomes of pars plana vitrectomy in severely traumatized eyes with no light perception (NLP) and flat electroretinography (ERG) Methods: We performed a prospective interventional study on 22 severely traumatized eyes with NLP, 4+ relative afferent pupillary defect (RAPD) and flat ERG. Results: One year after pars plana virectomy, 15 patients (68.18%) had NLP, six patients (27.27%) had light perception and one patient (4.54%) could count fingers at 70 cm. There was a significant improvement in final visual acuity (VA) (p=0.02). There was no significant association between mechanism of trauma, type or site of laceration, age, sex, ocular comorbidities, type of the surgery or mean number of vitrectomies and final VA. Conclusion: If the anatomical status of the eye permits (such as lack of optic nerve avulsion), and also in the presence of specific situations (as in one eyed patients), vitreoretinal surgery could be thought for the preserving at least some vision and also to conserve the appearance of the globe and to help the psychological state of the patient.
