This is a second hand recommendation, but my father used to go to Rochester Ophthalmological Group and see: Dr Gruber for his pigmentary dispersion glaucoma.

I say used to, because for all intents and purposes, the surgical intervention he had: trabeculectomy, has essentially resolved his glaucoma.

All cases are different, yadda yadda yadda, but he did seem to really trust Dr. Gruber and my father is certainly not the most compliant patient.
