Multimodal Imaging in a Long-standing Case of Pattern Dystrophy

Abstract

Purpose: The aim of this study is to report the case of a patient diagnosed with butterfly pattern dystrophy (BPD), which during yearly follow-up visits developed a concomitant pachychoroidal neovasculopathy (PNV). Methods: Case report focusing on the role multimodal imaging in patients with pattern dystrophies (PDs) Case report: We describe a case of a 52-year-old woman,which was initially diagnosed with BPD by fundus examination, fundus autofluorescence and optical coherence tomofraphy findings. Interestingly, during yearly follow-up visits, the presence of a thickened choroid bilaterally associated with the onset of concomitant choroidal neovascularizations (CNVs) in the right eye was made possibile by adopting multimodal imaging, in particular optical coherence tomography angiography. Fluorescein angiography and indocyanine green angiography findings helped us to make the diagnosis of PNV. Conclusion: We described for the first time a case of PD, which after several years progressed to PNV. Hence, we deem that multimodal imaging and in particular optical coherence tomography angiography represent an important diagnostic tool in the management of PDs.
