Focal Choroidal Elevations: Localized Pigment Epithelial Contour Alterations due to Isolated Choroidal Vessels

Figure 3

Imaging features of a small focal choroidal elevation in a patient with early atrophic age-related macular degeneration. (a) Color fundus photograph demonstrating drusen and the position of a subtle pigment epithelial elevation (arrowhead) observed on ophthalmoscopy. (b) Fundus autofluorescence reveals no specific abnormality in the region. (c) Scanning laser ophthalmoscopic image; green arrow corresponding to SD-OCT raster in (d). There is a subfoveal drusenoid pigment epithelial detachment and a focal choroidal elevation (FCE) corresponding to the region observed in (a); mean macular choroidal thickness = 105 μm; FCE lumen diameter = 126 μm.
