Especially when the follow-up, vision helps physicians understand the effect of treatment, disease progress, and decide the next step in treatment.

Patients with recent cardiovascular accidents (heart attack, cerebral infarction, heart failure, pulmonary edema, pulmonary embolism and other poor systemic conditions) should inform the physician in advance.
