Anybody here with “dry eyes syndrome of bilateral lacrimal glands”? Can somebody clairfy what the percentage is for it?

I didn’t know it was claimable and I had it diagnosed in service and was given eye drops for it since I had a pretty bad case and still do. What’s the percentage for it when claimed?

Mine says dry eye syndrome of bilateral lacrimal glands HO4.123. So to get 10 or 20 percent does it depend on symptoms ? How does it work?
