[Functional Results and Prognostic Factors in Open-globe Ocular Trauma with Presenting Visual Acuity of No-light Perception]

Purpose: 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.

Materials And Methods: 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.

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 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).

Conclusion: 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.
