[Functional results and prognostic factors in open-globe ocular trauma with presenting visual acuity of no-light...

To analyse the clinical ocular characteristics and determine prognostic factors for functional recovery in eyes presenting with no light perception (NLP) after open globe ocular trauma.

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

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 size was greater than 10mm in 9 patients (60 %). The ocular lesions included expulsion of the crystalline lens or posterior chamber intraocular lens, hyphema, retinal detachment, vitreous hemorrhage and ciliochoroidal lesions. Damage to the ciliary body was a negative prognostic factor for functional recovery (P=0.04). Nine patients remained with no light perception, whereas 6 patients experienced an improvement in visual acuity (2.3 logMAR in 3 patients, 0.7 logMAR in 1 patient, 0.4 logMAR in 1 patient and 0.2 logMAR in 1 patient). These 6 patients had undergone posterior vitrectomy due to vitreoretinal involvement (P<0.001).

In the case of open globe trauma with no light perception on presentation, a functional recovery is possible if there is no irreversible anatomical damage.
