I have a condition called best disease in my left eye, Now in my good eye I had all the test done for same condition and opthalmologists told me that I have a healthy retina. Now my problem is that when I look at a blank white space or for example at the sky I notice a shimmer in my peripheral vision. Different doctors could not find anyhing! What is this?
No way, from your brief description, and the fact that examining ophthalmologists have told you your eyes are normal that we can give you a diagnosis. If it persists I would suggest seeing a neuro-ophthalmologist and having a peripheral vision test.
