Multilayered Exudative Bacillary Layer Detachment in Active Choroidal Neovascularization: A New Optical Coherence Tomography Sign

Abstract

In this article, we present three cases diagnosed with active choroidal neovascularization (CNV): two cases diagnosed with neovascular age-related macular degeneration (nAMD), and one case with myopic CNV in an elderly eye that presented a characteristic and unique optical coherence tomography (OCT) sign consisting of well-defined, circular-shaped multiple concentric layers of alternating iso-hyperreflective material located between the external limiting membrane and outer photoreceptor layers, which seems to be a multilayered bacillary layer detachment (BALAD). Multilayered exudative BALAD in active CNV may be a new and characteristic OCT sign. [ Ophthalmic Surg Lasers Imaging Retina 2024;55:92–94.]
