Analysis of progression of reticular pseudodrusen by spectral domain optical coherence tomography
Purpose: To analyze reticular pseudodrusen progression using SD-OCT. Methods: Thirty-three consecutive patients (48 eyes) underwent Spectralis SD-OCT using the eye-tracked follow-up protocol 24+/-2 months after baseline examination. Each pair of B-scans (only 1 per eye was evaluated among those showing pseudodrusen progression) was compared with respect to pseudodrusen appearance and retinal layers structure. Stage 1 pseudodrusen was defined as granular material between the RPE and the IS/OS, stage 2 as mounds of material sufficient to alter the contour of the IS/OS, stage 3 as thicker material adopting a conical appearance and breaking through the IS/OS, and ...
