Traumatic optic neuropathy in orbital wall fractures- diagnostic parameters and treatment outcomes: A prospective observational study

Abstract

IntroductionThe aim of the study was to evaluate the associated patterns of orbital wall fractures, diagnostic parameters of Traumatic optic neuropathy and its progress with Mega dose steroid therapy. Materials and Methods25 patients with unilateral orbital wall fractures of traumatic aetiology were evaluated with ophthalmologic and radiographic parameters. All patients were prescribed Mega Dose Intravenous steroids irrespective of the timing of presentation. Ophthalmic assessment was repeated for same parameters every alternate day upto 2 weeks. ResultsLateral orbital wall was found to be most commonly involved. Visual acuity, Pupillary Reactivity, Visual Field and Visual Evoked Potential showed statistically significant improvement post steroid therapy in early as well as late presenters. DiscussionHighest incidence of Traumatic optic neuropathy was noted in multiple linear orbital wall fractures with highest incidence with lateral orbital wall involvement. Literature regarding Choice and timing of initiation of steroids based on timing of presentation is inadequate to justify skipping steroids to observe or undertake surgical intervention. In the present study marked improvement was noted post steroid therapy regardless of timing of presentation. The authors conclude that Visual evoked potential should be objectively tested and Mega dose steroid therapy should be initiated for all patients with Traumatic optic neuropathy for maximum benefit to the patient.
