        This visit was for a consult/second opinion. Dr. Cowley identified an issue with a retina that was completely missed by the first physician I saw at Washington Retina Center. She is truly an expert in her field. I am a graduate of the JHU and remain impressed with the consistent outstanding quality of the physicians at JHM.
