I posted on you other thread and then saw this one. It is possible that the sinus infection caused some visual disturbances that you are experiencing. I've had my share of sinus infections and quite often I have experienced trouble with my vision (mostly blurry vision). My DD21 gets visual disturbances when she has a sinus infection (nystagmus). It is possible that the infection extended in to your optic nerve. I'm glad you are getting other tests done and will be seeing a neuro-ophthalmologist soon.
