The value of normal clinical data.

As optometric practitioners, we all gather and then analyze large quantities of clinical data every day. We understand that some of these data will be normal (or negative), and some will be abnormal (or positive); some will even be questionable (unreliable or suspicious). However, all clinical data used to prevent, diagnose, treat, and/or rehabilitate our patients are important; therefore, patients--as well as third-party payors--should be reminded of this fact.
