Also on the page where I was reading about this, ophthalmologist was misspelled. So I searched through the documents until I found a contact link--almost everything was phone numbers, even though I was using the web--until I finally found something, so I wrote:
- You have misspelled ophthalmologist at a page on glaucoma screening
https://www.cms.gov/GlaucomaScreening/
The phth only appears in a few words in English, but on a government web site, it should be spelled correctly.
