“Bear track” CHRPE (Congenital Hypertrophy of the Retinal Pigment Epithelium) appears as multiple darkly pigmented lesions resembling bear tracks on fundus examination. Diagnosing CHRPE is important to differentiate it from other pigmented retinal lesions and to monitor for associations with familial adenomatous polyposis (FAP) in atypical cases. In imaging, CHRPE is not visible on the blue channel, appears minimally in the green channel, but is strongly highlighted in the red channel, enhancing lesion contrast.

Bear track CHRPE refers to multiple, grouped lesions of congenital hypertrophy of the retinal pigment epithelium, resembling bear paw prints. These benign lesions are typically harmless and found during eye exams, requiring no treatment. However, these lesions can be associated with familial adenomatous polyposis (FAP), a genetic condition that increases colon cancer risk, necessitating systemic evaluation for FAP.
