PARACENTRAL ACUTE MIDDLE MACULOPATHY AS A PRESENTING SIGN OF CENTRAL RETINAL ARTERY OCCLUSION IN SICKLE CELL DISEASE TREATED WITH TISSUE PLASMINOGEN ACTIVATOR.

Abstract

We report the case of a 27-year-old monocular woman with a history of sickle cell disease who received intra-arterial tissue plasminogen activator (tPA) after presenting with acute painless vision loss secondary to incomplete central retinal artery occlusion presenting as paracentral acute middle maculopathy in her left eye. Ultrawidefield fundus photography, ultrawidefield fluorescein angiography, en face optical coherence tomography (OCT), and optical coherence tomography angiography (OCTA) were obtained and reviewed, followed by cerebral angiography and infusion of intra-arterial tissue plasminogen activator. A patient with a history of sickle cell disease presented with a new onset of a dense central scotoma, and the visual acuity diminished to 20 of 200 from baseline 20 of 20 in her left eye. Fluorescein angiogram was nondiagnostic. Optical coherence tomography revealed perifoveal hyper-reflective bands in the inner nuclear layer in a pattern characteristic of paracentral acute middle maculopathy. The patient received intra-arterial tissue plasminogen activator through her left ophthalmic artery shortly after presentation, resulting in a gradual restoration of the visual acuity to 20 of 20 in the three months after the procedure. This is the first report describing the use of intra-arterial tissue plasminogen activator to treat incomplete central retinal artery occlusion presenting as a paracentral acute middle maculopathy lesion in a patient with sickle cell disease.
