A girl in her teens with a history of postconcussion syndrome was referred for retinal evaluation after failing her vision examination for her learner's permit for driving. She complained of progressively declining, blurred vision for 2 years. She denied floaters, flashes of light, headaches, and eye pain. The patient had a concussion 1 year prior after becoming dehydrated during marching band practice, fainting, and hitting her head on pavement. Her postconcussion symptoms included headaches, dizziness, and dysarthria. The headaches and dizziness resolved but the dysarthria remained. Brain magnetic resonance imaging (MRI) within the last year was normal. She denied acute vision changes after the concussion. Family history was unremarkable for vision loss, glaucoma, inherited retinal degeneration, and autoimmune disease.
