COVID-19 associated with a Purtscher-like retinopathy
Investigators at the Eye Clinic, Department of Medicine, Surgery and Health Sciences, University of Trieste, Trieste, Italy, found that the appearance of the retina and optic disc was associated with the SARS-CoV-2 virus.
A patient in Italy presented with acute painless vision loss in both eyes, his visual acuity reduced to counting fingers.
Marco Pastore, MD, from the Eye Clinic, Department of Medicine, Surgery and Health Sciences, University of Trieste, Trieste, Italy, worked with some colleagues to find the appearance of the retina and optic disc was associated with the SARS-CoV-2 virus.
The investigators described that the ophthalmoscopic examination showed “multiple polygonal areas of retinal whitening at the posterior pole and around the optic disc associated with mild optic disc edema, nerve fiber layer infarcts, and macular edema with pseudo-cherry red spot” in both eyes.
The results of optical coherence tomography (OCT) imaging showed “inner retinal hyperreflectivity, diffuse retinal thickening with intraretinal fluid, and a serous macular detachment.”
The investigators diagnosed an paracentral acute middle maculopathy that was associated with capillary nonperfusion of the intermediate and deep capillary plexuses.
The patient underwent testing for the SARS-CoV-2 virus, and polymerase chain reaction confirmed the infection.
Laboratory tests showed that both the C-reactive protein and D-dimer levels were increased. The patient was negative for any infectious diseases. Pastore and his colleagues diagnosed Purtscher-like retinopathy associated with COVID-19. Treatment included intravenous methylprednisone (1,000-mg dose) for 7 days followed by oral corticosteroids.
Two months after the initial presentation, the vision improved from counting fingers to 20/32 and 20/25 in the right and left eyes, respectively. In addition, the authors reported that the detachment resolved with focal subfoveal ellipsoid zone disruption and reduced hyperreflectivity in the inner nuclear layer and outer plexiform layer.
