Resolution of traumatic mydriasis and accommodative dysfunction eight years after sweetgum ball ocular injury.
Overview
abstract
PURPOSE: To present a case of traumatic mydriasis (MD) and accommodative dysfunction (AD) secondary to a sweetgum ball ocular injury that resolved 8 years after the inciting trauma. OBSERVATIONS: A 6-year-old female presented with left eye ocular trauma after being hit with a sweetgum ball. Sweetgum balls are the small, spiky fallen fruits of the American Sweetgum tree (Liquidambar styraciflua). Due to their size and shape, children often use them as projectiles during play. On presentation, the patient had a partial thickness corneal laceration, traumatic mydriasis (TM), and accommodative dysfunction (AD). Her corneal laceration was repaired. Her TM and AD persisted. She was treated with bifocal spectacles and patching. At her 7-year follow-up visit, her TM and AD showed minimal signs of improvement. Eight years post-injury, her TM and AD had both improved significantly. CONCLUSION AND IMPORTANCE: Sweetgum balls, when used as projectiles, pose a risk of serious ocular injury. Pupillary and accommodative function in TM may improve much later than previously appreciated. Young age may contribute to parasympathetic neuroregeneration. Patching may have prevented amblyopia in this case, allowing her left eye to achieve its full visual potential once her pupillary and accommodative function returned.
