  • Foveoschisis secondary to high myopia

    Mar 13 2015 by Niloofar Piri, MD

    Infrared and HD-OCT of the right eye in a 55-year-old African American female with high myopia (more than -6.00 D), BCVA: 20/25 OU Cartwheel appearance of the fovea in the infrared imaging is visible. HD- OCT demonstartes schisis in different layers of the retina (both NFL and OPL; notice stretching of the Muller cells); VMT is also present . Outer retinal layers are preserved which explains the good vision . She had the same findings in OS.

  • AMN (Acute Macular Neuroretinitis) #2

    Apr 28 2019 by Niloofar Piri, MD

    HD-OCT image of 53-year-old man who presented with a superior small paracentral scotoma for 1 month. He had very small hypopigmented area inferior to the fovea and hyporeflectivity on NIR image ( #1). OCT demonstrated a vertical hyper-reflective band extending from OPL to RPE. This form is type 2 AMN which is due to occlusion of deep capillary plexus.

  • Plaquenil Toxicity: "Flying Saucer"

    Feb 25 2021 by Niloofar Piri, MD

    SD- OCT of the same patient with hydroxychloroquine (Plaquenil) toxicity, demonstrating classic "Flying Saucer" pattern secondary to parafoveal RPE atrophy, and outer retinal layer disruption including EZ loss, and outer nuclear layer loss.
