Can you give me some additional information?
1. Her age?
2. Do she suffer from any medical conditions?
3. Is she taking medication?
4. Aside from blurry vision, any eye pain or redness of the eyes?
5. Has she seen a rhematologist or eye doctor for symptoms?
This will help me evaluate the case better...
The undiagnosed nerve and muscle condition that your daughter is suffering from could have an autoimmune link. If this is the case, vision is frequently affected in the form of blurry vision. Sometimes the eyes can become light sensitive and become red. I'm not exactly sure about the condition you read about in the past.
Conditions such as Lupus, Rheumatoid arthritis or Multiple sclerosis should be considered as possible etiologies. The best recommendation I can make is a visit to a rheumatologist and an ophthalmologist as there is no substitute for a complete exam with appropiate studies to reach the appropiate diagnosis and treatment.
I hope this offers some guidance and good luck as you look for some relief to her condition...
