    Acute macular neuroretinopathy (AMN) is a rare condition characterized by acute photopsia, paracentral scotoma, and reduced visual acuity.

  • 2

    Paracentral acute middle maculopathy (PAMM) is distinguished from AMN by hyperreflectivity of the inner nuclear layer on OCT imaging.

  • 3

    Recent studies suggest that choroidal hypoperfusion may be the primary mechanism underlying AMN, challenging previous beliefs about deep capillary plexus involvement.

  • 4

    The study aimed to quantify choroidal thickness and vascularity index in AMN and compare findings with PAMM to refine the distinction between these conditions.

  • 5

    A retrospective, multicentric study included patients diagnosed with AMN and PAMM, adhering to ethical guidelines and obtaining informed consent.
