ABSTRACT
PURPOSE:
To characterize cross-sectional images of idiopathic polypoidal choroidal vasculopathy (PCV).METHODS:
A cross-sectional and retrospective study was performed involving 28 eyes with PCV and 112 eyes with exudative age-related macular degeneration. The frequency and dimensions of the retinal pigment epithelial detachment (RPED) with attenuation of internal reflectivity on optical coherence tomographic (OCT) examination were compared in both diseases.RESULTS:
OCT showed the RPED with attenuation of internal reflectivity corresponding to the polypoidal structure in the indocyanine green angiogram in 75% of eyes with PCV, which was significantly more frequent than in eyes with exudative age-related macular degeneration (3.6%). In lesions suspicious of exudative age-related macular degeneration or PCV, the RPED with attenuation of internal reflectivity on OCT images strongly supported PCV diagnosis with a sensitivity of 84% and a specificity of 94%. The base diameter (p=0.010) and base diameter times height (p=0.028) of RPED were smaller in PCV than in exudative age-related macular degeneration.CONCLUSIONS:
An RPED with attenuation of internal reflectivity in OCT examination is a highly sensitive and specific finding which characterizes PCV. Recognition of this RPED appearance, as well as the evaluation of its size, aids in the diagnosis of PCV.Palabras clave
