To investigate the prevalence of a newly defined drusen type, pachydrusen, soft drusen, and subretinal drusenoid deposits (SDDs) in eyes with polypoidal choroidal vasculopathy (PCV) and fellow eyes and the relationship between each drusen type and the choroidal thickness, vascular morphology, and hyperpermeability.
The 169 eyes of 90 patients with PCV were retrospectively reviewed. The prevalence of each drusen type was evaluated using color fundus photography and optical coherence tomography (OCT). The choroidal thickness and presence of pachyvessels on OCT and choroidal vascular hyperpermeability on indocyanine green angiography were compared among the drusen groups.
Pachydrusen, soft drusen and SDD were found in 49.3, 12.3 and 6.9% in PCV eyes. The mean subfoveal choroidal thickness of the pachydrusen, soft drusen, and SDD groups was 403.1, 184.4, and 176.4 µm. The pachydrusen group showed significantly thicker choroid than the others. The choroidal hyperpermeability was noticed at 41.7, 0, and 0% and the pachyvessel was observed at 80.6, 44.4, and 40% in pachydrusen, soft drusen, and SDD groups, respectively.
In PCV patients, pachydrusen was prevalent and associated with thicker choroid. PCV with pachydrusen was highly associated with choroidal vascular hyperpremeability and pachyvessel morphology than other types of drusens.
