Dry eye revenue for optometrists

[littlemermaid]

Dry eye ODs, figures on revenue, reimbursement, co-pay: 'In addition to the revenue you generate through dry eye testing, follow-up visits and treatment, the patient’s satisfaction may earn you more referrals. Financial rewards come when you change the lives of your patients. When we put the patient first, the rest falls into place.' http://www.revoptom.com/content/d/dry_eye/c/40351/

Are optometrists diagnosing dystrophies and systemic disorders successfully? Are they referring for prescriptions when inflammation is still not managed?
