I do not have the eye issues you report, but I do have eye issues.
The muscles that control the movement of my eyes were affected pretty early (for both eyes), which is apparently unusual.
I was referred to an neuro ophthalmologist, who diagnosed extraocular ophthalmoplegia. This is apparently a progressive condition that leads to paralysis of the muscles that control the movement of the eye.
I have never had any noticeable eye twitching or any other symptoms, except for difficulty moving my eyeballs around.
