Paracentral Acute Middle Maculopathy in Giant Cell Arteritis

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: A 72-year-old woman with PAMM as the presenting ophthalmic manifestation of GCA was described with a review of the prior cases from the literature. It was found that there were 26 cases of PAMM in GCA. In 19 of 26 cases, PAMM was associated with no other fundus abnormalities and was only seen on multimodal imaging including optical coherence tomography. CONCLUSION: PAMM can cause acute paracentral visual loss, and GCA should be suspected in all cases of PAMM of the elderly patients, even when isolated and not associated with constitutional symptoms of GCA.
