Today evening, I suddenly developed blurry vision in my left eye. It was concentrated in the lower part of my vision only. Difficult to describe, but it seems like my vision was overlapping and flickering. I got anxious and started getting panic attack. after one hour, the symptoms subsided and my vision became normal. I want to know why did it happen and what should I do? This had happened to me previously, but it was almost 2 years ago. That time complete checkup was done and consultation with neurologist was also taken and everything was okay.
