You cannot treat anyone until a diagnosis is made, or at least symptom control or empirical treatment. Its quite possible to attend a clinic or hospital for investigations and not be treated. I understand that in this instance, there is an attendance at a clinic for an eye problem.
It is not unusual for someone to present with a physical set of symptoms which either consciously or unconsciously cause the person to go to a doctor.
Conscious or deliberate attendance? Perhaps the person wanted to speak to a doctor but his employment would put him in some kind of jeopardy if he reported mental difficulties. Best go to the doctor with en eye problem?
