Background and objective: Spectral domain optical coherence tomography (SD-OCT) should be used to examine lesions containing retinal angiomatous proliferation (RAP) to achieve a better understanding of the origin of this pathology.
Patients and methods: In this prospective, observational case series, patients with RAP underwent retinal thickness imaging with Stratus OCT and cube 200 X 200 imaging with Cirrus OCT.
Results: A total of 12 eyes from 11 patients were included in the study. Of these, eight eyes had stage III RAP and four eyes had stage II RAP. Cirrus OCT detected the hyperreflective area corresponding to the neovascularization in all 12 eyes and Stratus OCT detected this pathology in 10 of the 12 eyes. All stage III lesions contained a retinal pigment epithelial break, which was more visible in the 200 x 200 scans obtained from Cirrus OCT compared with six radial scan lines obtained from Stratus OCT.
Conclusion: Cirrus OCT had considerable advantages compared with Stratus OCT, particularly in investigation of juxtafoveal pathology.
