title: [Optical coherence tomography imaging in commotio retinae: case report].
abstract: The purpose of this case report was to correlate optical coherence tomography findings and visual outcomes of patients with different degrees of commotio retinae. A 20-year-old male and a 23-year-old male that presented with decreased vision due to Berlin's edema after blunt ocular trauma were evaluated by optical coherence tomography and retinography. The visual acuity in the affected eye was 20/25 in the first patient and counting fingers in the second one. The ophthalmic examination showed traumatic uveitis and fundoscopy revealed mild retinal opacification in the first case and severe opacification in the latter. The optical coherence tomography confirmed the reduction of foveal depression on the first case and the disarrangement of all retinal layers on the second. There has been complete functional and anatomical resolution by optical coherence tomography in the first patient, while the second evolved to permanent visual loss. Optical coherence tomography is a useful method in the evaluation of retinal trauma, helping to understand its physiopathology and to predict its prognosis through the anatomical analysis of the affected region.
