Ultrasonic evaluation of eyes with blunt trauma

Purpose The aim was to present the common A-B scan ultrasonography (US) and ultrasound biomicroscopy (UBM) signs in Egyptian patients with blunt ocular trauma and compare them with the clinical findings. Materials and methods This prospective study included consecutive patients with blunt ocular injury attending the outpatient clinic of Mansoura Ophthalmic Center during the period from October 2013 to October 2014. All patients were subjected to thorough ophthalmic examination. All patients underwent US to assess the posterior segment of the globe and UBM for evaluation of the anterior segment. Results A total of 95 eyes of 95 patients were recruited in the study. Overall, 68% of them were males, and 73.7% were younger than 40 years. Stick and stone injuries were the causes of blunt ocular injury in 27.4 and 23.2%, respectively, and 42.1% of the patients had visual acuity between hand motion (HM) and perception of light (PL). Using UBM, traumatic hyphema was detected in 47.4% of patients whereas iridodialysis was seen in 26.3% of patients. The commonest findings in B-scan US were vitreous hemorrhage and retinal detachment (21.1% each). B-scan US and UBM detected structural changes that were missed or could not be detected by clinical examination especially with opaque media, which was statistically significant in cases of angle recession. Conclusion The findings of this study support the combined use of B-scan US and UBM in the evaluation of eye with blunt trauma
