I was quite fortunate, it could have been far more serious.
I hope you make a full recovery. So far I've just had 'normal' eyesight problems: mainly myopia and age-related presbyopia, both of which can be solved by the appropriate glasses.
As you rightly say, any sudden vision changes should be examined professionally as soon as possible. Sometimes a delay can lead to permanent problems that could have been avoided with earlier treatment.
