Optical Coherence Tomography Findings Following Orbital Fractures.

Introduction: A closed globe trauma is often associated with orbital wall fractures. In addition to diplopia, further eye disturbances can be observed. The aim of this preliminary prospective study was to investigate the optical coherence tomography (OCT) findings in patients that presented with orbital fractures in association with diplopia but without decreased visual acuity or further ocular symptoms.

Methods: Only patients who were admitted and surgically treated for orbital wall fractures and that presented diplopia were included in this study. Patients with post traumatic ocular symptoms were excluded. All the patients that were diagnosed with an orbital fracture underwent an ophthalmological assessment, including best-corrected visual acuity (BCVA), examination of fundus oculi, Hess Scheme, OCT, and OCT angiography.

Results: Five patients met the inclusion criteria and were enrolled. Hess Scheme examinations confirmed the presence of diplopia in all the included patients. The examination of fundus oculi did not reveal any pathology in 4 patients, whereas in a patient a commotio retinae (Berlin's Edema) was diagnosed in the infero-papillary field. Following OCT assessment, a pachycoroid was observed in 4 patients.

Conclusions: A thorough ophthalmological assessment in patients that have suffered from orbital fractures is fundamental. In particular, OCT examinations seem to provide more insight into the detection and monitoring of choroidal changes after ocular trauma without visible macular changes.
