It stands to reason that there will be a relationship between muscular disease and eye focusing problems, since the eye is a muscle and can be affected as well.

One of the most common of the muscular diseases, which affect the eye, is muscular dystrophy. There are several different types of this disease, including one called oculopharyngeal muscular dystrophy, which is actually a weakening of the eye muscle itself.

Other neuromuscular diseases which show problems with the patient’s ability to focus properly; include myotonic muscular dystrophy (MMD), myasthenia gravis (MG), congenital myasthenic syndromes, and mitochondrial disorders.

All of these conditions are characterized by what is considered weak levators. The levator palpebrae superioris muscle is the one that lifts the upper eyelid. When the levators are weak, it results in a drooping of the eye, or the eyelid. This will in turn have an impact on the ability to focus properly.
