:Paracentral acute middle maculopathy (PAMM) is a relatively new optical coherence tomography finding, defined by hyperreflectivity in the inner nuclear layer. In this article, we present a case of a 73-year-old woman who presented with transient vision loss followed by the sudden onset of complete vision loss to counting fingers at 1 foot for one day in the left eye. Dilated examination showed a right cotton wool spot, left pallid optic disc edema, and retinal edema in the distribution of the cilioretinal artery. OCT demonstrated hyperreflective band at the level of the inner nuclear layer, compatible with PAMM. Clinical and laboratory findings were consistent with GCA, for which she was prescribed high-dose oral prednisone, with confirmation of GCA on a subsequent temporal artery biopsy. PAMM may be seen in the context of GCA, and OCT of the macula serves as an important adjunct to define the retinal manifestations of this condition.
A 93-year-old woman presented with a 1-day history of sudden painless vision loss in her right eye with a background of new temporal headaches and jaw claudication. Dilated fundus examination of the right eye showed mild retinal whitening and edema throughout the right fundus with selective sparing in the distribution of the cilioretinal artery. A diagnosis of giant-cell arteritis (GCA) was made and confirmed with temporal artery biopsy. Oral prednisone was initiated and her vision improved to 20/200 in the right eye at 3-month follow-up. GCA-related cilioretinal artery sparing central retinal artery occlusion is rare and may have mild improvement with promt treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
