Yup, I have this. I'm partially blind (visual field defects in both eyes, in other words my field of vision is like looking through a piece of swiss cheese) and have had a lot of problems utilizing the vision I do have remaining, including not using peripheral vision, eyes not working together, etc. O&M is a great idea--the more skills and ways to do things you have, the better. I would absolutely see the specialist, just in case, but don't hold your breath. I still don't have a diagnosis and I've had vision issues from birth. Specialists have documented my condition but have never helped me in any way, lol.
In addition to O&M, if possible, try to see a behavioral optometrist, neuro-optometrist, and/or an occupational therapist with experience with vision issues. Those are the people who can help you use the vision you have to the fullest extent. After my vision deteriorated further a few years back, I lost so much functionality, it was demoralizing and horrible. I worked with a behavioral optometrist and it was a game changer. She gave me an Rx for
$1, which really helped, and worked with me on balance, scanning for information, and other skills. Now I can use the computer, ride the bus, etc. with no issues!
