Andrea P. Thau, OD, FAAO, FCOVD, of Dr. Andrea P. Thau and Associates in New York City, says that if new in practice, or even if you are established, vision therapy offers growth opportunities. It is a revenue-builder as a fee-for-service specialty. It also is a strong generator of referrals for a patient population (children and young families) that often has yet to choose an eye doctor. Remarkably, one successful case in vision therapy can provide up to 50 referrals.
