Analysis of Progression of Reticular Pseudodrusen by Spectral Domain–Optical Coherence Tomography
Purpose. To analyze reticular pseudodrusen progression using spectral domain–optical coherence tomography (SD-OCT). Methods. Thirty-three consecutive patients (48 eyes) underwent SD-OCT using the eye-tracked follow-up protocol 24 ± 2 months after baseline examination. Each pair of B-scans (only one per eye was evaluated among those showing pseudodrusen progression) was compared with respect to pseudodrusen appearance and retinal layer structure. Stage 1 pseudodrusen was defined as granular material between the RPE and the inner segment/outer segment (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 ...
