Abstract :
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.
