Paracentral Acute Middle Maculopathy As the Presenting Sign of Ischemic Cardiomyopathy

Paracentral acute middle maculopathy (PAMM) is a type of ischemic maculopathy affecting intermediate and deep retinal capillary plexuses. A typical presentation is acute onset scotoma with or without vision loss. It is characterized by greyish-white parafoveal lesions. Sometimes very subtle lesions can be missed on clinical examination. The main diagnostic modality is spectral domain optical coherence tomography (SD-OCT) wherein focal or multifocal lesions are seen as bands of hyperreflectivity in the inner nuclear and outer plexiform layers. This entity can be associated with systemic microvascular diseases. Here, we report an interesting case of PAMM as the only presenting sign in a patient with ischemic cardiomyopathy, highlighting the necessity for a thorough systemic examination in such patients.
