[Optical coherence tomography biomarkers for neovascular age-related macular degeneration : Relevance for the diagnosis, treatment and prognosis].

Abstract

Comprehensive multimodal imaging is essential for the precise clinical diagnostics of neovascular age-related macular degeneration (nAMD). Noninvasive optical coherence tomography (OCT) is of prime importance regarding the baseline examination, follow-up and monitoring during treatment. The OCT imaging in nAMD eyes enables a high-resolution assessment of the retinal micromorphology, which can be considerably disturbed in different layers. A large number of pathological OCT alterations represent distinct micromorphological OCT biomarkers. These should be taken into account in the assessment of OCT images. This article covers the following important biomarkers: intraretinal, subretinal and subpigment epithelial fluid, outer retinal tubulations, ellipsoid zone integrity, hyperreflective foci, subretinal drusenoid deposits, onion sign, hyporeflective prechoroidal cleft, double layer sign, subretinal hyperreflective material and bacillary layer detachment.
