Thank for replying.
If the pupils are of unequal size ( called anisocoria
) , one pupil appearing more dilated than the other , of recent onset , should raise the suspicion of a problem in the visual pathway ( along the optic nerve ) . Such a optic nerve lesion ( usually an inflammation in the optic nerve called optic neuritis
) presents with sudden onset of reduced vision
, dilated pupil with ill-sustained pupil reflex ( not necessarily fixed and maybe RAPD) , visual field defects along with impaired color vision.
If your vision is blurry but pupil is now not dilated and reacting to light , then there may not be any optic nerve problem , no glaucoma
( associated with dilated pupil with severe eye pain , nausea , blurred vision ).
I suggest you have a look at the pupils again and if you still find that there is difference in the size and reaction of the two pupils , then it is better to get your eyes examined at the earliest to look at the back of the eye ( by fundus exam ) by an ophthalmologist
Thanks and best wishes
