Bilateral myopia following blunt trauma to one eye.

PURPOSE To evaluate bilateral myopia following blunt trauma to one eye. CASE REPORT Traumatic myopia is a rare transient situation which may be seen in the injured eye or both eyes after blunt ocular trauma. We examined one case with transient myopia in the left eye which had been exposed to a blunt ocular injury. Myopia was also observed in the right eye 12 hours after the trauma. The right eye and left eye had reverted to emmetropia respectively two and six weeks after trauma. DISCUSSION The myopia may have been due to ciliary spasm arising from stimulation of the efferent autonomic system in the right eye and ciliary body edema in the left eye. CONCLUSIONS To our knowledge, this is the first reported case developing bilateral transient myopia after the blunt trauma to only one eye.
