PARACENTRAL ACUTE MIDDLE MACULOPATHY (PAMM) IN GIANT CELL ARTERITIS.

ABSTRACT

PURPOSE: To describe a representative case and review the literature on paracentral acute middle maculopathy (PAMM) and giant cell arteritis (GCA). METHODS: A review of the English language ophthalmic literature was performed using the search terms of PAMM, giant cell arteritis, and temporal arteritis. RESULTS: We describe a 72-year-old woman with PAMM as the presenting ophthalmic manifestation of GCA with a review the prior cases from the literature. We found a total of 26 cases of PAMM in GCA. In 19 out of 26 cases PAMM was associated with no other fundus abnormalities and was only seen on multimodal imaging including OCT. CONCLUSION: PAMM can cause acute paracentral visual loss and GCA should be suspected in all cases of PAMM of the elderly, even when isolated and not associated with constitutional symptoms of GCA.
