10 Carbon Monoxide Poisoning Symptoms
Symptom #9: Blurred vision
The eyes have a large oxygen demand compared with other body parts (except the brain). Thus, when they are exposed to acute or chronic carbon monoxide poisoning, serious effects on vision can be reported. Furthermore, if left untreated, some effects can become permanent.
Blurred vision, extreme light sensitivity, and double vision (diplopia) are some of the visual disturbances that can occur in carbon monoxide poisoning. Symptoms can either have a late-onset or they can present suddenly upon exposure to the gas. In some people with this condition, the physician, upon performing an eye exam, might notice a visual field loss or a loss in the entire area that can be seen by a person when their eye is fixed straight at a specific point. This and other signs of carbon monoxide poisoning on an ophthalmologic exam are rare.
