How Often Are Visual Fields Necessary?
Participant: How often should a patient ask for a visual field test to help allay fears of rapidly losing vision? Dr. Rick Wilson: If field loss is mild to moderate and the IOPs seem controlled, then yearly. If the IOP is above normal and the glaucoma is mild, then every 9 to 12 months. If the loss is moderate to severe, then every 6 months. I rarely get visual field tests more than every 6 months, unless the patient develops new symptoms that may be related to visual field loss.
