  • Title: Pigmented lesions of the retinal pigment epithelium and familial adenomatous polyposis.
    Author: Polkinghorne PJ, Ritchie S, Neale K, Schoeppner G, Thomson JP, Jay BS.
    Journal: Eye (Lond); 1990; 4 ( Pt 1)():216-21. PubMed ID: 2157613.
    Abstract:
    Bilateral pigmented fundus lesions were found in 65 out of 72 patients with familial adenomatous polyposis, an additional five patients having unilateral lesions. With a family history of familial adenomatous polyposis, the occurrence of multiple bilateral fundus lesions indicates the presence of the abnormal gene, as does the occurrence of oval pigmented lesions with surrounding pale haloes. The absence of pigmented fundus lesions does not exclude the abnormal genotype, while the presence of occasional pigmented spots can be found in an appreciable percentage of the population. Ocular examination would, however, appear to be valuable in screening those at risk, with a positive yield in most carriers of the gene for familial adenomatous polyposis.
