I was extremely concerned about a retina that may have started to detach. Dr Heyden did a very thorough examination. Upon completion he explained what I was experiencing was 'floaters', somewhat normal for a person of my age. Dr. Heyden explained that my retina is in good condition and that the floaters could possibly go away in time. I asked several additional questions -pertaining to my eyes- and Dr. Heyden explained them all very well to me. He spent all the time with me that was necessary to do a complete and through examination. I highly recommend the ESA to anyone needing vision care.
