Hello My father had 3 brain strokes which affected his balance ,memory and left side .. and unfortunately one of them hit his vision centre. It s been 9 months now and he still can t walk on his own and he s not even balanced enough. He got in a comma and when he woke up he only saw whitness .. now he sees some colors .. but nothing else .. he can t see any kind of details .. neither people nor objects. His sadness got him diabetes and i m afraid that will make him see blackness instead of some colors in the area. We re Egyptians By the way so medical care is not as evolved as is the US In fact they e idiots and couldn t tell what was wrong with him for years .. even when he had the stroke until he got in the comma. That s pretty much the summary . So can his vision centre be fixed? Here they re saying no but i don t trust them.
