retinal drusen reticular pseudodrusen https://github.com/monarch-initiative/mondo/issues/9849 SDD subretinal drusenoid deposit MONDO:1060213 RPD Reticular pseudodrusen are a strong independent risk factor for late age-related macular degeneration and are particularly associated with geographic atrophy and type 3 neovascularization. SCTID:762533006 A retinal drusen characterized by subretinal deposits located internal to the retinal pigment epithelium, composed of material aggregations in the subretinal space between photoreceptors and the retinal pigment epithelium. These deposits have a bluish-white appearance by biomicroscopy and appear as hyperreflective lesions above the retinal pigment epithelium on optical coherence tomography.
