My retina surgeon says it does not...mg cause macular degeneration, but do take supportive vitamins if you know or believe you have it. My right eye has it so bad that I go every 90 days for a shot to the right eyeball to keep the macular degeneration at bay. Have had at least 12 shots to the right eyeball and not one hurt and getting the shot does not have any impact on mg.

Does myasthenia gravis (MG) cause macular degeneration or other eye problems? The good news is that MG does not cause macular degeneration. MG doesn't damage the retina or optic nerve, so it won't lead to permanent vision loss or blindness.

Does myasthenia gravis (MG) cause macular degeneration or other eye problems? The good news is that MG does not cause macular degeneration. MG doesn't damage the retina or optic nerve, so it won't lead to permanent vision loss or blindness.
However, MG can cause several eye-related issues, particularly in its ocular form. Here are the most common ones:
- Ptosis – drooping of one or both eyelids, which can partially or fully block vision
- Diplopia – double vision caused by weakened eye muscles becoming misaligned
- Blurred vision – difficulty focusing due to fatigued eye muscles
- The curtain effect – drooping worsens in one eye when the other is lifted
- Peripheral vision loss – a droopy eyelid can limit side vision
These symptoms often fluctuate throughout the day, typically worsening later in the day or after prolonged eye use, like long-distance driving or reading. In severe cases, ptosis can cause what's called functional blindness — where eyelids droop so much they cover the pupils entirely. This isn't permanent damage, but it can seriously impact daily life.
If eye symptoms are interfering with work or daily activities, it's worth speaking with a doctor about treatment options, which may include medications like pyridostigmine (Mestinon) or corticosteroids to help manage muscle weakness.
