DEAR DR. GOTT: I have a question regarding the eye disorder, pigment dispersal syndrome (PDS). I have never seen this discussed in your column, which I read every day.

I’m a very active and healthy 66-year-old male with no other health issues at present. I was diagnosed with this by my ophthalmologist.
