Optical coherence tomography findings in commotio retina. 
A 16-year-old boy presented with diminished visual acuity of 6/60 following blunt trauma to his right eye with a cricket ball.  Fundus examination showed commotio retinae.  Optical coherence tomography (OCT) demonstrated increased reflectivity with small optically clear spaces in the area corresponding to the photoreceptor outer segment.  At 2-month follow up the visual acuity improved to 6/6.  A small area of retinal opacification persisted nasally, and OCT of the corresponding area continued to show increased reflectivity in the area of photoreceptor outer segment.  Increased reflectivity on OCT in eyes with commotio retinae probably denotes photoreceptor outer segment disruption and seems to be reversible to a variable extent.
