Can clonazepam suddenly cause binocular double vision when reading in a person who has been on the drug for 4 years. 1mg qhs for ptsd.

Not that i know of: If you have developed sudden double vision, you need to either see your primary care physician for a referral, or see an eye specialist. You can start with an optometrist who can do an initial evaluation and potentially refer to an ophthamologist if needed. Double vision usually occurs because of muscle weakness in the muscles which control eye movements, which may be neurological/muscle disease.

No: This is not caused by the drug. Double vision is a serious sign that needs evaluation. An ophthalmologist is the type of doctor you should see.
