I recently was diagnosed with 4th nerve palsy as well showing the same symptoms as you, all the tests & blood work & doctors as well, It is very hard to read watch tv, ride my bike & especially drive, actually as of yesterday I have stopped driving it's too stressful.
The doctors said to wait 6 months & if it is not better surgery is iminant, Do you have any alternative ideas to share the thought of surgery doesn't thrill me .
I am 57 years old & in perfect health.
