Abstract
Introduction: Traumatic eye injuries (TEI) involved about 3% of cases referred to the emergency departments of developing countries. Lens dislocation is one of the critical cases of ophthalmic emergencies. The present study was aimed to evaluate the diagnostic accuracy of ultrasonography in detection of traumatic lens dislocation. Methods: In this cross-sectional study the findings of ultrasonography and orbital computed tomography (OCT) of head and face trauma patients, referred to Imam Reza hospital, Tabriz, Iran, from July 2013 to June 2014, have been compared. The sensitivity, specificity, positive and negative likelihood ratio, positive and negative predictive value, and accuracy of ultrasonography were calculated. Cohen's kappa coefficient was presented to assess the agreement of ultrasonography with OCT findings. Results: One hundred thirty patients with the mean age of 35.4±18.0 were evaluated (75.4% male). Sensitivity and specificity of ultrasonography were 84.6% (95% Cl: 53.7-97.3) and 98.3% (95% Cl: 93.3- 99.7), respectively. Also, positive and negative likelihood ratio were calculated 49.5 (95% Cl: 12.3-199.4) and 0.15 (95% Cl: 0.04- 0.56), respectively. Cohen's kappa coefficient of 0.83 (95% Cl: 0.66-1.0; p<0.0001) was representative of excellent agreement of these two tests. Conclusion: The finding of this project was representative of 84.6% sensitivity, 98.3% specificity, and 96.9% accuracy of ultrasonography in detection of traumatic lens dislocation. It seems that in cases which OCT is not possible, ultrasonography could be an acceptable option to assess traumatic eye injuries.- Ultrasonography
