Abstract
Objective: To describe the imaging characteristics of polypoidal choroidal vasculopathy (PCV). Subject and method: A cross-sectional study on 43 eyes (41 patients) who were diagnosed with PCV on ICG at Vitreo-retinal Department, Vietnam National Eye Hospital from October 2013 to February 2020. Result: Mean age was 60.49 ± 9.21 years old. There were 21 male patients, 20 female patients. The characteristic features of PCV on OCT were dome shaped PED (62.8%), finger liked (16.3%) and doubled layers (25.6%). FA was of low value in PCV diagnosis. The definitive diagnosis was confirmed on ICG with solitary form (76.7%) and grape form (23.3%). The locations were foveolar (69.8%), peri-papillary (25.6%) and outside temporal arcade (4.7%). PCV with branching vascular networks was seen in 76.7%. Conclusion: The imaging features of PCV were copious. If OCT findings were important but nonconclusive, ICG diagnosis was specific and precise.
