During which type of appointment would an optometric technician typically perform a vision screening?

A vision screening is an essential component of both initial consultations and follow-up assessments, making the choice of both correct. During an initial consultation, a vision screening helps establish a baseline of the patient's vision and detect any immediate concerns that may need further evaluation. This is crucial for setting the course of the patient's care and determining the need for additional diagnostic tests.

In follow-up assessments, vision screenings are used to monitor the patient's progress and the effectiveness of treatments or interventions that may have been implemented during previous visits. This ongoing evaluation ensures that any changes in vision are promptly addressed, maintaining the health and performance of the visual system.

In contrast, initial consultations and follow-up assessments involve different aspects where vision screenings play a critical role, while emergency visits might focus more on acute issues rather than comprehensive screenings. Therefore, the correct answer acknowledges the importance of vision screenings in both types of appointments.
