Structural en face optical coherence tomography in neovascular and nonneovascularage-related macular degeneration: Use and utility in clinical practice

Age-related macular degeneration (AMD) is a leading cause of blindness and visual impairment worldwide. Structural en face optical coherence tomography (OCT) is an innovative imaging technology that has recently attracted interest because of its potential for assessing AMD features. We conducted a comprehensive review of its application in AMD. In neovascular AMD, structural en face OCT can detect exudative activity, monitor the neovascularization area, study the choroid in polypoidal choroidal vasculopathy, and visualize neovascular membranes in pigment epithelial detachments. Moreover, in nonneovascular AMD, this study provides details on geographic atrophy and drusen, the identification of intraretinal retinal pigment epithelium migration, and the detection of different patterns of outer retinal tubulations. Our study revealed that structural en face OCT can provide relevant information on patients with AMD.
