How might myotonic dystrophy type 1 associated vision problems be treated?

Treatment of eye and vision problems must be individually tailored. Refractive error and astigmatism can be corrected with eyeglasses, contact lenses, or surgery. Special glasses with eye "crutches" can be used to improve vision in people with ptosis. Surgery can be done to treat ptosis and cataracts, however ptosis often recurs and special precautions must be taken with anesthesia.[1] If severe, strabismus may also be treated with surgery.[1]

Does myotonic dystrophy cause fatigue?

Yes. Sleepiness and fatigue are common features of myotonic dystrophy type 1. Medications to reduce fatigue are available. We recommend that you dicuss your treatment options with a healthcare provider.[1]

In addition, heart block is a common and potentially dangerous complication of myotonic dystrophy type 1, that can cause light headedness, dizzy spells, near fainting, and fainting. These symptoms should be reported to your doctor right away.[1]
