A behavioral optometrist is quite different from a vision therapist. The one behavioral optometrist I have encountered did a good job of ferreting out whether a reading issue was a serious developmental vision problem or something else. (No dyslexia here, so I can't tell you whether he would have been helpful there.)
However, once an actual vision problem was ruled out, he couldn't go to the next step and look for other kinds of LDs and cognitive problems; he definitely couldn't have isolated dysgraphia based on the tests he did. You can get a positive ID on physical eye problems from someone with these qualifications, but possibly not the whole story.
I'd say, go ahead and see the behavioral optometrist; but be prepared to take further steps afterward if you don't get useful answers.
