Visual Field Defect

A patient came into the office complaining of blurred vision. He had a history of diabetes and multiple sclerosis. The patient, with glasses, saw pretty clearly. There weren't any signs of disease when I looked at the back of his eye. When I performed visual fields on the patient, the lower right quadrant of his field of vision was gone. this condition existed in both eyes. This could be diagnosed as a right field quadrantopsia.

When a field defect appears in the same area for both eyes, it's generally not a problem with the eyes but a problem with the brain. A stroke or a tumor could cause such a problem. I referred the patient back to his neurologist to make him aware of the situation. I could not diagnose what exactly caused the defect in the fields.
