OBJECTIVES: To evaluate the diagnostic capability of spectral domain optical coherence tomography (SD-OCT) in patients with potential diagnostic findings for polypoidal choroidal vasculopathy (PCV).
MATERIALS AND METHODS: Ninety-three eyes with potential diagnostic findings for PCV were prospectively evaluated. Patients with multiple retinal pigment epithelial detachment (RPED), sharp RPED peak, RPED notch, hyporeflective lumen representing polyps, double-layer sign and the presence of hyperreflective intraretinal hard exudate were considered as PCV in SD-OCT. The sensitivity and specificity of SD-OCT in the diagnosis of PCV were determined by comparing SD-OCT-based diagnosis with indocyanine green angiography (ICGA).
RESULTS: Sixty-nine (74.2%) of 93 eyes included in the study were confirmed with ICGA and diagnosed as PCV. The sensitivity and specificity of SD-OCT for the diagnosis of PCV were 75.3% and 75%, respectively.
CONCLUSION: The SD-OCT-based method helps clinicians to develop appropriate diagnostic and treatment strategies for patients in whom ICGA cannot be used.
