Functional outcomes and prognostic factors for eyes with no light perception after open globe ocular trauma.

Abstract

Purpose : To analyze the clinical ocular characteristics and determine prognostic factors for functional success in eyes presenting with no light perception after open globe ocular trauma.

Methods : In this retrospective study were included all the patients with no light perception after an open globe trauma who presented to Amiens University Hospital between October 2014 and June 2018.

Results : Fifteen eyes of 15 patients were included in this study. The main mechanism of the trauma was globe rupture (80% n=12). The most common location was zone III (66% n=10). The wound’s size was greater than 10 mm for 9 patients (60%). The ocular lesions were the expulsion of the crystalline lens or of the posterior chamber intraocular lens, hyphema, retinal detachment, vitreous hemorrhage, and ciliochoroidal lesions. Damage of the ciliary body was a negative prognostic factor for the functional recovery. Nine patients remained with no light perception whereas 6 patients improved their visual acuity (2.3 logMAR for 3 patients, 0.7 logMAR for 1 patient, 0.4log MAR for 1 patient and 0.2 logMAR for the last one). Those 6 patients had undergone a posterior vitrectomy, following vitreoretinal damages (p<0.001).

Conclusions : In case of open globe trauma with initial no light perception, a functional recovery is possible if there is no irreversible anatomical damages.
