Question by SuzieQ92: I am hoping someone who has experienced this will answer. We have a 73 year old relative in another state?
who is experiencing double vision. She had a stroke in one eye many years ago, so she doesn’t see well out of that eye at all. She has been having double vision in her one good eye for over a month now. She has been to the eye doctor a couple of times, and he took her off of all medication that could cause double vision. The condition hasn’t improved.
The weird part is that she doesn’t see double in everything, but only words. When she tries to read street signs or books or words on television, she sees them double.
About 6 weeks ago, she had cataract surgery on her bad eye. Could cataract surgery adversely affected her good eye?
The doctor has ruled out any structural problems with the eye, so what could the other possibilities be that only words are seen double?
Thank you for any help you can give!
I tried to get in touch with RM, but he/she doesn’t allow e-mail. She has monocular double vision. The double vision is still there no matter which eye is covered.

Answer by RM
1. She almost certainly has binocular double vision, meaning if you cover one eye the double vision goes away. This is by far the most common type and is caused by misalignment of the eyes (for a lot of possible reasons). If for some reason she has monocular double vision then it is usually a problem in the eye itself.
2. My guess is that she has double vision for everything (meaning the misalignment of the eyes is always there) but she only notices it when reading due to the extra fidelity needed and some irritating overlap of letters.
There’s long list of possibilities to explain the misalignment. I’d start with her ophthalmologist because there’s a good chance its related to the cataract surgery (lens replacement not at the perfect angle?). If he doesn’t know then you should ideally go to a neuroophthalmologist to help sort it out.
Edit: Monocular double vision that is present in both eyes is extremely rare but not impossible (esp. since there is a possible stroke history). I have to say that its so rare that I have some doubt that its really present but if it is then it would be due to a problem in the occipital lobes of the brain. HOWEVER, if it really is monocular double vision then I suspect it is only in one of her eyes with the eye that had the cataract surgery being most likely (a problem in that lens). Get her eye doctor to check it. If she really has bilateral monocular double vision you should have her see a Neurologist also….or, better yet, a Neuroophthalmologist if there is one in your area.
