Characteristics of Polypoidal Choroidal Vasculopathy in OCT Angiography in Latin American Patients.

BACKGROUND AND OBJECTIVES: To describe the imaging characteristics of polypoidal choroidal vasculopathy (PCV) in optical coherence tomography angiography (OCTA) and demonstrate its use as diagnostic method for this pathology in a Latin American population. PATIENTS AND METHODS: A case series. RESULTS: Fourteen eyes were evaluated. At baseline, the most frequent morphology was the "oval" type (76.9%), obtaining a reduction of 53.8% after treatment. The intrinsic finding of the polyps was hyporeflective content prior to treatment (80.8%), which reduced after treatment (7.7%) (P = .016). CONCLUSIONS: OCTA is a useful imaging tool for detecting findings that can guide the diagnosis of PCV without contrast medium. Likewise, it provides signs that can suggest the behavior of the lesion prior to and after treatment, enriching the understanding of the pathology and therefore aiming to an efficient therapy. To the best of the authors' knowledge, this is the first study in a Latin American population.
