PURPOSE: Monochromatic blue-light fundus autofluorescence has proven to be particularly useful for the detection of optic disc drusen (ODD). The aim of this study was to investigate how accurately novel confocal scanners can detect ODD by means of color fundus and autofluorescence images.
METHODS: Images were taken in 20 consecutive patients' eyes with funduscopically visible ODD using the TrueColor Eidon AF (60 × 55°) and the spectral domain Spectralis HRA+OCT (30 × 30°). The features of ODD, including localization, extent, and intensity patterns of autofluorescence were compared and correlated with retinal nerve fiber layer (RNFL) thickness in OCT and perimetry findings.
RESULTS: Mean patient age was 46 ± 6 years (6 females, 4 males). The TrueColor Eidon AF enabled accurate localization and extent estimation of the drusen area. Drusen presented as a homogeneous signal. The predilection site of ODD, which was nasally pronounced in >80% of cases, was associated with thinning of the RNFL and corresponding visual field defects.
CONCLUSION: The TrueColor Eidon AF allows reliable detection of superficial ODD in nondilated eyes. Extended observational studies are needed to determine the value of this noninvasive, nonmydriatic procedure in terms of follow-up and progression analyses of ODD.
