The comparison of spectral domain optical coherence tomography and indocyanine green angiography in the diagnosis of polypoidal choroidal vasculopathy.

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.
