Live Better With Double Vision from Myasthenia Gravis
Double vision is a common symptom of myasthenia gravis, a chronic condition that causes muscles to grow tired easily. Having double vision can be deeply frustrating and get in the way of daily activities and favorite pastimes. But if you or someone you care for has periods of double vision caused by myasthenia gravis, there are a number of things you can do to help.
What Causes Double Vision in Myasthenia Gravis?
Myasthenia gravis causes your body to mistakenly attack the links between nerves and muscles. This affects the tiny muscles that work in sync to keep your eyes properly aligned. As the muscles weaken, your eyes tend to get out of alignment. This leads to double vision or seeing two images when you look at an object. Myasthenia gravis may also cause your eyelids to droop, which can block your vision. You might also be bothered by bright light.
If you have double vision and other visual symptoms caused by myasthenia gravis, you may notice that they get better or worse from day to day. You might be more likely to see double images later in the evening or after you’ve been reading or using your eyes intensely for a long period.
Double vision and other sight problems are the first symptoms for about half of people who get myasthenia gravis. Roughly 85% of them will also have muscle weakness in other body parts. This is known as generalized myasthenia gravis. The rest will only have visual symptoms, a condition called ocular myasthenia gravis. Men appear to be more likely than women to develop ocular myasthenia gravis.
