My right pupil is slightly larger than the left. The right eye also has a bit of trouble focusing when I cover the left, however it's ability to distinguish #'s, lertters, words,etc. Seems to be fine. In your opinion, is this a case of a "lazy eye"? If this is a lazy eye, is surgery an available option for treatment? If so what is the success rate? I am 24 yrs. Old. Also is treatment covered by most medical insurances?
