I suddenly have a shadow over part of my vision. Do I need an appointment?
Sudden loss of vision or a new shadow covering part of your visual field needs prompt medical attention, even without an appointment. During business hours, call the clinic to check whether an urgent examination is available. If immediate evaluation is not possible or the clinic is closed, go to a medical facility that provides emergency eye care.
