The Role of Spectral-Domain Optical Coherence Tomography in the Diagnosis of Retinal Angiomatous Proliferation

Abstract

We present the findings of spectral-domain optical coherence tomography (OCT) in 8 patients with retinal angiomatous proliferation. Eight patients with a known history of age-related macular degeneration presented with a recent decrease of visual acuity in one eye. On fundus examination, all patients showed an elevated macular lesion associated with intra- or subretinal hemorrhage and retinal hard exudates. Fluorescein and indocyanine-green (ICG) angiography, together with spectral-domain OCT (Optopol Copernicus SOCT), were performed. Fluorescein angiography showed early hyperfluorescence with late leakage in all cases. A serous pigment epithelium detachment was present in 6 cases. ICG angiography showed a hot spot in the macular area. The OCT showed a serous pigment epithelium detachment in 6 cases and intraretinal cysts in all cases. The line crossing the ICG visible hot spot showed a greatly hyperreflective intraretinal lesion located at various depths inside the retina. Spectral-domain OCT is a useful complementary tool to confirm the diagnosis of retinal angiomatous proliferation. Its high resolution and speed enables accurate localization of the angiomatous lesion.
