PURPOSE To illustrate a potentially concerning artifact on Optos wide-angle imaging.
METHODS Case report.
RESULTS A healthy 11-year-old girl, with no medical history, was found to have a lightly pigmented superotemporal choroidal tumor, suspicious for melanoma, which was detected on Optos wide-angle imaging by her optometrist. On referral to the retinal specialist, the mass was not visible on funduscopy. B-scan ultrasonography depicted flat retina and no visible mass. Review of the Optos image revealed that the pseudomelanoma represented the patient’s nose.
CONCLUSION Optos wide-angle imaging provides broad retinal imaging; however, artifacts from patient positioning can lead to the nose artifact.
