From: In-vivo high resolution imaging of optic nerve head drusen using spectral-domain Optical Coherence Tomography

Figure 1

Color fundus photograph, FAF imaging, B-scan ultrasound and Spectralis OCT of subject 1. Color fundus photograph revealed yellow white surface calcareous deposits on the optic nerve head (A). FAF imaging of the same subject demonstrated autofluorescence of the surface drusen (B). B-Scan ultrasound showed echodense lesion overlapping the optic nerve shadow. The reflectivity persisted at 30 decibels (C). Cross-sectional Spectralis OCT image of drusen revealed the 'cap' sign (arrow), an empty space lined by high reflectivity signal (D). NFL: Nerve fibre layer, RPE: Retinal pigment epithelium.
