Q. What could be the reason for reduced vision in my left eye following a head injury?
Hi doctor,
I am a 33-year-old male and have used prescription glasses for myopia with astigmatism with a power of -4 and -3.75. A few days back, I hit o my head on my car trunk and hit my head at the top right back side somewhere between the apex and parietal region of the right side of the head.
There was no concussion, bleeding, bruise, swelling, dizziness, or other symptoms. After the incident, I had no headache but slight tenderness, which lasted for a few hours. The only symptom I noticed after two days is my left eye vision is not as clear as my right. Everything is clear when I read things close to my eyes, but my left eye gets a little blur reading small texts far away. There is no other symptom. I am very worried and panicking about whether I have any internal bleeding in the brain in that area. Can this be due to any internal bleeding, or can it be due to a change in my eye power? Kindly help.
Hi,
Welcome to icliniq.com.
I read your query and understand your concern.
As per your description, there was no headache, loss of consciousness, vomiting, or any symptoms apart from vision, and your head was hit on the right side. Now your observation about the vision problem is on the left eye, which is only in far vision. With such history, it seems unlikely to be due to head bumping.
Moreover, with history, we cannot tell the exact cause of this far vision impairment and cannot rule out any internal injury. There have been cases that develop internal bleeding after trivial injury too. To rule out your concern, I would suggest MRI (magnetic resonance imaging) brain, including orbits, and in-person consultation with ophthalmologists. Kindly revert for more queries.
Thank you.
Thank you for your reply doctor.
I also want to add that I have another pair of glasses that has a slightly different power, and I am finding that when I wear those, my far vision of my left eye gets 50 percent clearer than my current glasses, but it is not same as the right eye in terms of clarity. So can we now say that this is a refractive issue of the eye and that a change in prescription can fix the far vision of the left eye? Can I now believe that internal injury will be unlikely, given I have no headache or other symptoms? Kindly help.
Hi,
Welcome back to icliniq.com.
As per your description that by changing the spectacle, you are able to see better with the left eye. This point is more in favor of left eye symptoms due to refractive error. But to rule out internal bleeding after a head bump, consult an ophthalmologist.
Thank you.
