Dr. Kardon shared the story of a patient with a unilateral temporal visual field defect. OCT imaging revealed retinal thinning in the outer retina corresponding to the location of the visual field defect who had degeneration of the photoreceptors due to acute zonal occult outer retinopathy.

    “With the temporal visual field loss, we would normally send this patient out for a scan,” Dr. Kardon said. “But with the results of her OCT, we were able keep this patient in the office, avoid having to obtain a brain MRI, and make the correct diagnosis. This shows how the technology can work both ways.”
