2+ years post-injury, suddenly developed binocular double vision after visual overload. Has anyone else experienced this?
Hi everyone,
I’m hoping to hear from people who’ve experienced something similar.
I sustained two motor vehicle accident-related concussions (March and July 2024) and have been dealing with persistent post-concussion syndrome for a little over two years.
My ongoing symptoms have included headaches/migraines, neck pain, cognitive fatigue, light and noise sensitivity, dizziness, and visual fatigue.
Earlier assessments also documented convergence insufficiency, impaired saccades, and even nystagmus during testing. I was referred for a neuro-optometric assessment and possible vision therapy months ago, but that never ended up happening because the auto insurance company denied the assessment.
My current ongoing physio regularly includes vestibular and vision exercises.
Until this week, I had never experienced persistent double vision.
This past Saturday I had some mild nausea and a sensation of being “on a boat,” but it mostly settled, I was fine on Sunday and Monday morning.
Then on Monday afternoon , I spent about an hour actively trading stocks using multiple monitors and multiple charts. It involved constant scanning, rapid eye movements, and sustained concentration.
I felt completely normal before I started.
After about an hour, my left eye began feeling like it was “lagging.” Shortly afterward I developed binocular double vision (it disappears completely if I cover either eye), severe dizziness, nausea, and eventually vomiting.
The double vision persisted into the next day, so I went to the ER.
The ER physician observed abnormal eye movements and nystagmus during the examination.
I told them this was already documented by multiple professionals including physio and OT and IE assessments. It wasn’t an entirely new phenomenon.
They performed bloodwork, ECG, and a CT angiogram of my head and neck to rule out stroke and other emergencies. Fortunately the imaging was negative for stroke, but they couldn’t determine the exact cause and referred me to both ophthalmology and neurology.
Right now the double vision is still present whenever both eyes are open. Covering either eye eliminates it.
I’m not looking for anyone to diagnose me over Reddit. I’m simply wondering:
Has anyone else developed new binocular double vision years after their concussion, rather than immediately after the injury?
Did anyone have symptoms that were triggered by visually demanding tasks like multiple monitors, gaming, coding, or trading?
If you had something similar, what was the eventual diagnosis? (decompensated convergence insufficiency, cranial nerve palsy, vestibular issue, something else?)
Did it improve over time?
If vision therapy, prism lenses, or neuro-optometry helped, what kind of timeline did you experience?
I’m honestly pretty discouraged because this feels like a major setback after two years of rehabilitation, but I’m hoping to hear from people who’ve been through something similar.
Thanks in advance.
