I am a neuro-ophthalmologist. I treat a lot of double vision. Having PD predisposes to divergence insufficiency -- side by side doubling in the distance-- and to convergence insufficiency -- side by side doubling when you try to read. One or both of these would be far more likely than having PD and Myasthenia gravis.
